Lister Based Generators / Re: Lister HRW Injector Sleeve Install Tools
« on: October 21, 2016, 03:56:11 PM »
So I have since learnt from my black book of usual suspects that the belling tool has a piece of 1/4" thick or so rubber on the end that physically expands as you hammer the tool to expand the copper at the end.  I reckon now that I understand it I can fashion something off note.  Regarding pictures, would you be providing pictures from the manual or something better because i already have a a good clear copy of a manual picture of the tools which I now understand better now that I get the rubber piece on the end.

Lister Based Generators / Lister HRW Injector Sleeve Install Tools
« on: October 21, 2016, 12:21:48 PM »
Hi,
I need to replace some Injector copper sleeves on Lister HRW cylinder heads. I have the sleeves but no install tools.

Thinking either borrow or get pictures and dimensional drawings so that I can make them on a lathe.

Cheers

Excellent Doug, I was hoping somebody from the motor shop trade would fill in the gaps on my somewhat generic description.

Enough good advice with regards to getting the pulley off etc so I will not add to that however some thoughts in regards to cleaning:

The danger here is that you'll encourage shorts deep in the windings that you will not be able to get out.  Motor shops do indeed steam clean with water and appropriate solvents however they then bake them to drive the moisture out.  This baking is either external in an oven or internal by passing current through the coils in a controlled manner to help dry things out. They then dip in the appropriate class insulation coating and bake again.  Also note the steam cleaning is low pressure IIRC 25 PSI or so, you do not want to drive the dirt inside the windings as this will itself contribute to the shorts and or hold the moisture in.  The caveat here also is that the older the unit the higher the risk of creating or not being able to get rid of moisture causing shorts in this process.  When having old DC equipment rebuilt I have had the odd unit not come back and one unit spent along time in the oven trying to get the moisture out.  Its a double edged sword with an old unit on the one hand you want to get rid of the dirt because in itself it encourages shorts but on the other you may very well want to clean light enough that you do not make it worse.

Engines / Re: Infered temp tester
« on: June 23, 2009, 12:42:18 PM »
Granted its a HR so no coolant, however still exhaust temp should be used for balancing cylinders, taken as close to the head as possible.  For coolant engines accuracy is based upon the balance of the coolant flow etc and only really tells you somewhat as to how hard the cylinder in question is working.

How hard have you tried looking for this part?

Have you contacted Marine Engine Services, http://www.marineengine.co.uk tell Peter or Chris that Nobby sent you.
or
Peter Forbes AKA Listerdiesel, http://www.oldengine.org/members/diesel/index.htm

good places to start and very good knowledgeable people to deal with.  I good give you more contacts but it is small network and they all will somewhat just call each other anyways.  No point creating crossed wires so to speak

Red Stone Engines / Re: Redstone engines
« on: April 03, 2009, 04:39:14 AM »
John all the best with the Mk 2 resto, as far as I know still ranked one of the most popular getaway cars, so much so that the Police started using them.  Only wish I could get to putting my Austin A40 pickup on the road or my DS come to that.

Bob interesting concept, never viewed myself as an import and I am not sure if I will ever quite live up to the Redneck description, I love a good peaty Scotch to much to start drinking Bourbon, although I do own a 4x4 (diesel suburban though not pickup) and once the kids get a wee bit older I am sure that a gun will reappear in my life.  As to the car this is a somewhat before my time however I am thinking Shelby Cobra which incidently would of been an English AC Chassis/body shipped to CA for Shelby to power and then would of been shipped back to race.  If this indeed is the car you are referring to then I suspect that part of the Brit admiration for it was based on it being partly British also.  GT40 also sprang to mind but they came later didn't they, however how could you not love the lines on that car.

Now on topic, seems to me that hype is being built on both sides about the Redstone, I am seeing phrases along the lines of 100,000 hour and be and end all etc from the sceptical side and to be quite honest I do not believe that the sellers of the units are touting that at all nor is Bob come to that.  What I am seeing is a move away by the sellers from the Blister and a new avenue of finding an engine that is built with better QC and design that will be of little if any issue out of the box and give a good lifespan.  This based somewhat on a frustration with the poor QC of Blisters and in all reality the tough times they had getting the Indian producers to improve things, seems to me it left them as suppliers with an inability to truly stand behind the product.  I would certainly feel that way.  I can speak from personal experience how frustrating it can be when as a supplier you find issues with a product and cannot get the manufacturer to realise this and step up and make a remedy to the situation.  Also the thought of as a supplier having to strip a unit down and clean/rebuild before you sell it just seems plain bum about face to me.

This is a small niche market and seems to me that as a seller there would need to be a wee bit of initial secrecy as they set themselves up and invest in a product that will have fairly minimal sales and cannot stand too much competition.  I myself am working on a product idea and am currently telling no one about it as there really is only room for one or two sellers of this product within the US, one needs to be somewhat secure and setup when finally going public in a situation like this.  I do not see any real secrecy now though specs are published by John and George is posting pictures, so what that they have their own owners forum big deal.  I will say this though it is off putting that all we have stateside is Joels email address and no real website/source of info of his own, we do have Georges website giving info.  However as a potential customer and a businessman I strongly suggest that he puts something info wise out there himself no info from the horses mouth does help to fuel this skepticism and suspicion.

Bottom line is the proof of the pudding......... looks like we have a couple of step up to the plate offers and so i am sure we will all be watching this space for results.

Red Stone Engines / Re: Redstone engines
« on: April 02, 2009, 07:30:26 PM »
Well I am kinda of busy and was wanting to stay out of things right now, but you had to go bring Jaguar into this.  To be honest I am growing tired of all the Brit car bashing that I now experience living here in the States Lucas or not.  If Jaguar was such a pile of crap then how come it is ranked 4th in the most wins at Le Mans , one of the best tests of Vehicle Mechanics/Design longevity etc.  Lets put that observation into further perspective, Porsche is top however all of its impressive 15 wins are from 1970 onwards and really at a time when Jaguar was no longer really racing although there was a minor come back from Jag during this period.  Audi is number 3 and once again all its 8 wins are from 2000 and on so of no matter.  Which leaves us Ferrari ranked number 2 with 9 wins against Jaguars 7.  Now if I play real devils advocate here and ignore 2 of Jaguars wins because they are post 1970 that still leaves us 5 to Ferrari's 9.  That to me is impressive stuff especially considering the differences between the Jaguar and Ferrari companies etc back then.  Lets not forget that the E-type  IIRC won the SCCA twice within the classes that it raced in and as I understand it the secound time it was not one of the better funded teams.
The thing about Jaguar was that William Lyons goal was to create a poorer man sports/luxury car and IMHO he achieved that goal very well.

Now this went OT slightly however I am seeing an analogy here started by Doug in mentioning Jaguar perhaps the Redstone will become the poorer mans genset engine with a durability to match that of Jaguar exhibited at Le Mans.

China has more than one build quality, they can as far as I am concerned build quality stuff when they want as opposed to the usual junk that everyone is used to seeing.

Bob has reported good results from his own personal up close visual experiences on this engine and I for one based on all his input that I have seen here trust those reports.  Even if he does view me as a 'Non-Thinking Baboon' based on my political leanings!  ;)

Bottom line for me is that there is one reason why I would never buy a Listeroid, the simple fact that it arrives with a crankcase full off abrasive crud.  That right there speaks volumes about an engines quality of build and leads me to think no further on the subject.  The Redstone arrives clean that's a big tick in my book and gives some foresight into the build quality.

In all actuality this level of dissection is not applied generally to the purchase of engines, in our everyday lives do we really tear a new on the scene engine apart and minutely inspect it in every detail before purchasing it or the unit that it comes in?

Lastly this community consists of outside the box people trying to save a few bucks and have fun in the process.  Lets face it if we all wanted an easy safe solution we would all pony up the extra few thousand dollars and buy a ready made sound proof box genset or if we are trying to be frugal pick up a good used secoundhand one.  That do not come with eternal discussions on tons of crete, how to cool it, exhaust set ups etc etc etc.  So what if it has a couple of design teething issues, right now it's looking as though it does not have anywhere near the build flaws of a Blister and as far as a Changfa goes well Bob is already trying to figure out how to Justify buying one!  ;D

Bob b
I guess clarification is required, in your opinion spring mounts, cork mounts etc are not included in the term Resilient Mount within this discussion?

Sorry, not true.  Sure, natural rubber was available back then…but that doesn't mean it was possible to successfully design a resilient mount engine stand.  You will also note that I said "resilient mount technology" did not exist back then...and it absolutely did not.  The technology to analyze and understand complicated frequency and phase shifted dynamics (e.g., resilient mount engine) wasn't available before the 1950's.  This technology was not first used until the dawn of the missile and space age, and it wasn't readily used by engineers until computers allowed math modeling complicated dynamic systems using Laplace transforms.

I find your reasoning intriguing you are in effect saying that the science needs to be understood for design to be successful? The human race would not of got very far if that were the case.  Stone age man and his simple lever would be pretty much SOL building his henges then.

Lastly keep it online I am enjoying reading the physics of this discussion.

He He He, So I did the Math using estimates for a single using the formula presented in the text (Recommended by Leading Engineers) that I posted and according to that Lister was wrong it should be 1 1/2 ton or so.  ;D

900lbs, 625 rpm, constant of 0.16, -   900 x 0.16 x 25 = 3600lbs

Bob you have summed it up very well me thinks, some thoughts from me:

Resilient mounts were available back then so the argument that lister did not mention them because they did not exist is mute.  However looking at this in the context of their market etc,  strikes me that they more than likely did not want to muddy the waters/drive up install cost etc for the user to further go on and discuss resilient mounts/cork sandwiches etc.  Lets face it bolting directly to a ton of crete worked and in all reality just how much were people concerned about sound transmission back then in regards to lower budget intermittent usage engines.

Now in regards to the permanant install ton of crete method as the text I posted and others observe and my own opinion is that off sure go ahead and use resilient mounts on the crete, in fact IIRC that GF did observe himself in a previous thread that it was OK to Resilient mount on the crete block.

Now the portable is more interesting, to be honest I have no personal data to work with and all engines that I have worked on have had secure foundation either concrete or the frame/base of a ship and of course vehicle frames.  I have searched all my texts and have found no discussion pertaining to this.  The wide base stance that Bob discusses makes sense here, if I were to do this myself I think I would duly note the concerns as to crankshaft fatigue expressed by others and accept that as a possible issue and suck it and see.

Sorry but since when has an alleged lack of evidence of somebody dying on a wire been a satisfactory argument for just arbitarily plugging into the grid or in fact plugging in and staying plugged in without following proper procedure?  That's just foolish logic in my book.

Therein lies the point its not a case of whether you can back feed the grid or not, but that you need to follow the procedures/applications laid out by the utility company which do indeed vary from state to state, do it legitamately.  Which in the initial posts were not done he just supposedly plugged in!!!

Secondly and as equally important as already stated is SYCHRONISATION.  Now if he did indeed plug in and not fry the genset then he must of hit lucky and plugged in during the window when the genset was close to synch.  As I understand it from paralleling ships gensets with a synch meter there is a small window around the synch point where you can flip the breaker and the major power source (in this case the grid) will safely force the generator into synch.  Miss it and in the case of a true paralleling setup the breaker will not switch, in this case miss it and a short is created and sparks should fly.


Re the original question seems as though initially good input has been given, my only comment being that IIRC certain utilities etc do not allow grid tie with battery systems and can only be off-grid only.  This may of changed though as I learnt this on a PV net metering course several years ago.

I have gone back and read the prior ton of crete discussions and as Shipchief is pointing out the potential issue with resilient mounting etc for the CS style engine as I understand it is over the long term damage to the engine itself.  Ton of crete appears to be tried and tested as far as the years of CS engines operation will testify, but what to we have data wise for resilient mount 20,000 hours so far if I recall correctly from another thread.  Perhaps we have a trade off here quieter install with the risk of greater damage and fatigue in the long run.  To be honest as far as roids go and the relative cheapness of parts perhaps this really is a non issue in the bigger scheme of things.

One thing to bear in mind though in regard to the crete method is that the old school would float their crete within the building concrete foundation upon a vibration absorbing material the favorite and best being cork.  Other materials that could be used were soft rubber, mastics, asphalt or wood.  Very often on older ships you'll find the gensets mounted on wood and then the steel base of the engine room.  I would like to see vibration results of a crete mount, using a cork base must of given substantial positive results the old guys took great pains in installing this way.

I seem to recall GF being called out to provide documentation/formulas that discuss the ton of crete method well I have such a text material and will scan and post it, makes very interesting reading and also discusses resilient mount methods and is an 'old guy puplication (1940's)'.
