Engines / ST1 cylinder head gasket
« on: August 27, 2020, 11:12:37 AM »
Hi Guys, some of you will have seen that I purchased a small dumper truck. It has a Lister ST1 diesel engine, it is an absolute prick of a thing to hand start (no electric start).

My first thoughts on this was that the injector was dirty. Stripped it and cleaned it, I get a good spray pattern from it. Still a prick to start.

My second thought was lack of compression, so I took the head off it, followed by the cylinder and piston. The cylinder bore is OK, it has a couple of water marks in it where it has been sat idle for a time. The piston and rings look to be almost new, they are original Lister parts but have the numbers 040 stamped into the bottom of the piston. I believe that this indicates a +.040" oversize piston indicating that this unit has had a re-bore. There are also a lot of other indications that someone has been into this engine before me, silicon sealer rather than proper gaskets and etc.

Cylinder head looks to be OK, slight pitting in the valve/seats, I will lap them in the morning.

The cylinder and piston are now cleaned and reinstalled.

My question is a simple one: tomorrow I would like to fit the cylinder head and set the bump clearance. The problem I have is that these generally have a set of shims and a gasket between the cylinder and cylinder head. I have only one steel shim and no gasket. I am happy to make my own shims but I do not remember what the gasket should be made from. Is it paper, or some other material? How thick should it be? could I use a gasket sealer as an alternative? I could order a set of gaskets from the UK but delivery from the UK could take weeks.

Help/advice please,

Bob

Original Lister Cs Engines / Lister CS 6/1 running to slow
« on: August 22, 2020, 09:57:14 AM »
Hi Guys, a couple of very cold windy days have allowed me to have a bit of a play with my CS. It had a few problems with oil and fuel leaks. These issues have now all been resolved and she runs very well. The heat exchanger also works very well cooling the engine and heating the domestic hot water supply.

Having done all that I fitted the belts that connect it to the Chinese ST5 generator head. Not too surprisingly there was no output from the head, it has been standing idle for years. A quick flash of the windings and hey presto we have an output.

I did the calculations for the driven pulley wheel size based on the diameter of the CS flywheel rotating at around 650 RPM. The problem I have is that regardless of how tight I tension the governor spring the CS does not want to rev past about 400 RPM. It will rev higher if I manually apply additional pressure to the governor linkage. I have taken it up to 650 RPM using this method and the generator will put out 50 Hz, however the force required to overcome the governor weights is considerable and far higher than I would expect the governor spring to be able to overcome.

Thoughts please.

General Discussion / Absence from the forum
« on: October 22, 2019, 12:22:19 PM »
Hi Guys, sorry to have been away. My Father in Law passed away while my Wife was in New Zealand. Had to go to Sydney to make funeral arrangements and deal with the lawyers and etc until she got back. Funeral was on Friday and we got home yesterday.

Engines are a bit of a low priority this week, I will try to get back with the program and forum next week.

Engines / Replacing expensive old imperial bearings
« on: September 11, 2019, 09:49:39 AM »
Hi Guys, a while back I posted about an issue I was having with finding vintage Timken tapper bearings for an early 1950`s Cooper petrol engine. The bearings were available if I was prepared to cough up $350 each plus delivery and taxes. Rather than dump this nice vintage engine I decided to modify the crank shaft and housings to accept modern metric size tapper bearings. A lot of searching on bearing manufacturers web sites and a lot of phone calls to my local bearing supplier and I found NTN 32210 bearings would be an adequate replacement.

The outer diameter of these bearings is about 1.5 mm larger than the original, while the internal diameter is about 10 mm larger than the crankshaft, the width of the bearing is about 2 mm less than the original, a big issue with adjusting the end float! The load rating and life expectancy of the 32210 is a little lower than the originals but since one of the originals was still serviceable after 60 plus years I will have to live another fifty years to wear them out, not very likely but I live in hope!

The two housings have been in the lathe and bored out to take the 90 mm cup,  I have turned up two bushes to to enlarge the crank shaft from 1 9/16" to 50 mm, these have a 2 mm flange to allow for the difference in bearing width. This allowed me to cut gaskets to bring the end float back within tolerance.

I have posted some pictures, hope this will help someone in the same situation.

Everything else / Upcoming deceased estate sale
« on: September 10, 2019, 01:03:47 PM »
Hi Guys, found this deceased estate sale while searching for information on my Cooper XD lighting plant: https://petermilling.com.au/clearing-sale-2/24/

Hope there are a couple of cashed up Australian engine collectors who might be interested.

Everything else / Macksville rusty iron festival
« on: September 01, 2019, 09:23:00 AM »
Hi Guys, sorry for not posting much recently, been busy. I have been at the Macksville rusty engine rally. The call went out, last year, to beat the world record for the number of old stationary engines running simultaneously. The previous record was held by South Africa with 207 running for 10 minutes. Today Australia managed 333 old stationary engines running at the same time for 10 minutes! We could probably have got close to 400 but we had a few non starters. I will probably be coughing up the fumes and smoke for weeks to come.  :laugh:

So I guess that throws out the challenge to those of you in the rest of world, can you do better?

Bob.

Everything else / Antique generator control unit
« on: August 24, 2019, 10:34:29 AM »
Any one know what this is? (see photos) It appears to be some sort of a generator control unit, It has start and stop buttons and a large variable rheostat to adjust field winding voltage and thus output voltage. Found it in a pile of scrap in an old guys shed, gave him $30 for it. Any info much appreciated.

General Discussion / Brexit

As a Brit living in Australia I have watched the total paralysis of the UK government with a mixture of shock, horror, despair and disbelief. I am damned glad I live where I do, I would hate to be ruled by these idiots. I think the attached photo of the UK Prime Minister sums it up.

Things I want to Buy / Cooper engine circa 1925
« on: March 18, 2019, 10:44:32 AM »
Hi Guys, I had a very interesting outing with a mate of mine who took me to a shed in the middle of nowhere. The owner of this shed collects antique diesel tractors, he has dozens, all of which he has painstakingly restored to as new condition!

He also has a few old stationary engines which I would be interested in buying, so does anyone have any idea what a Cooper/Stover petrol engine made in the 1920`s is worth? See photos.

Other Slow Speed Diesels / Armstrong Siddeley 10 HP diesel engine
« on: February 24, 2019, 06:40:04 AM »
Hi Guys, I had a mate turn up today with an engine I have never seen before. It is a single cylinder Armstrong Siddeley 10 HP air cooled diesel. It is in remarkably good condition for it`s age, it turns over but has low compression (probably valve seats judging by the air hiss). I have been invited to help with the restoration of this beauty so if anyone has any information please get in touch. In return I will post pictures showing the internals of this beast, on the forum. I have posted a couple of pics to get your attention.

Other Slow Speed Diesels / Southern Cross ETB diesel engine
« on: February 13, 2019, 12:28:10 AM »
Hi Guys, I am awaiting the delivery of a Southern Cross ETB 2.5 HP diesel engine. Manufactured in Australia circa 1950, they were also manufactured briefly in South Africa. This engine has sat in a mate`s shed for the last 20 years. I have finally persuaded him to part with it for free!  :) 

Sadly it is incomplete, missing the fuel injector, pump and fuel lines. The originals would have been made by an Australian company called Pyrox, who manufactured injectors and pumps under license from Bosch.

I have been unable to find much out about the missing items but believe they are very similar to the units used on a Lister CS 3/1. I suspect that I might have to change the injector nozzles and fiddle with the pop pressures a bit to get them to work properly. Any thoughts please?

I have attached a photo of a complete ETB I found on the internet, probably a breach of someone`s copyright, for which I apologize in advance. I will post photos of my unit once it arrives.

Don`t see one of these every day. Never been run since manufacture. $5000 is way too rich for me but as a collectors piece it is probably priceless: https://www.gumtree.com.au/s-ad/warwick/collectables/vintage-lister-diesel-engine/1207228263

Hope someone can find it a good home.

General Discussion / Solution to lack of age care places in Australia
« on: January 15, 2019, 06:50:51 AM »
Hi Guys, my wife just received a text message outlining how to get around the shortage of age care places for the old and infirm:

Say you are an older senior citizen and can no longer take care of yourself and the government says there is no Nursing Home care available for you. So, what do you do? You opt for Medicare Plan G.
The plan gives anyone 75 or older a gun (Plan G) and one bullet. You are allowed to shoot one worthless politician. This means you will be sent to prison for the rest of your life where you will receive three meals a day, a roof over your head, central heating and air conditioning, cable TV, a library, and all the Health Care you need. Need new teeth? No problem. Need glasses? That's great. Need a hearing aid, new hip, knees, kidney, lungs, sex change, or heart? They are all covered!

As an added bonus, your kids can come and visit you at least as often as they do now! And, who will be paying for all of this? The same government that just told you they can't afford for you to go into a nursing home. And you will get rid of a useless politician while you are at it. And now, because you are a prisoner, you don't have to pay any more income taxes!

Is this a great country or what? Now that I've solved your senior financial plan, enjoy the rest of your week!
