I should have read the gaskets-to-go post first! ::)

Think i'll pull my head in...

These are to fit a Lister as opposed to a roid, ie 7 studs and dowels around two of the 3/4 " ones.Having said that, they should fit, they just have more and bigger holes.I'll be fitting some to my Dursley 10/2 when I get around to it, and they'd better not leak  >:(. the originals dont.
The ones on my Powerline don't leak either, so it's not areally good comparison. Come to think of it, I've never seen a Lister/oid leak water.You sure you guys aren't making it up? ;D ;D
 
I'll be happy to post some if anyone wants to try it on your side of the pond (Pacific this time)

STOP THE PRESS!!! :o :o
I just made a phone call to one of my customers and they have the tooling for 3/1 and 5(6)/1 head gaskets. Depending on who owns the tooling,we might even be able to get some custom made (choose your lining material) at less than AU 38.00 each. Anyone care to discuss this?
I'll keep you posted.

Cheers,

Brian.

3/1 head gaskets are available from Russell & Sons, Toowoomba (O7 4688 9222) @ about $38 each + tax.They also have valves, guides etc for most of the CS motors. Seems easier than making one!

Listeroid Engines / Re: Head Gaskets Weeping
« on: July 29, 2006, 06:56:13 AM »
Hi all,
I've finally started stripping my original 10/2. First observations are that the head gaskets look pretty close to the indian versions. Ok, there are 7 bolts vs 5, and 2 of the 3/4" ones are dowelled. I dont remember any dowels in the powerline. Wouldn't take too much to retrofit if you had the machinery and the interest.
The head gasket is crimped around the cylinder (obviously) but not around the waterways.The "asbestos" part has the appearance of the card used in cornflake packets. I seem to remember that the Powerline had a woven texture to it,more like glass cloth.It's easy to separate either variety at edges and waterways. This motor doesn't seem to have been weeping externally but there is a fair bit of rust on the top faces of the cylinders.
Being a Listard (non liner) bore there is no liner protrusion. Plenty of honing marks left in the bore,but I wouldn't have a clue how many hours are on it.
Does anyone know if the numbers on the castings are actually dates? If so, I have a 1939 crankcase with one 1944 cylinder. haven't seen a date on the other one yet.
 This may be a slow process. Next job is the dreaded broken gib key holding a Vee belt pulley to the crank.Original key came out of other side OK.

Cheers,

Brian

Engines / Re: Pour a concrete base as per Lister instructions.

Thanks, guys.
     I've never seen soil like that! Maybe I'll get my eyes tested after all! I've lived on three continents and never had to deal with frozen ground, but I understand it's a major issue for some of you.My biggest problem is BONE dry clay (hard as rock) and trying to keep the concrete moist enough to cure.
    I suppose we all have our crosse to bear..... :D

Listeroid Engines / Re: Roller rockers
« on: July 28, 2006, 10:58:24 AM »
Question from someone who hasn't got a clue... :D
   I was looking at a Lister A today ( that's a small version of a listerL, sidevalve petrol motor) and immediately noticed that the valves are deliberately offset from the lifters.On the L they're pretty much concentric (well, within 20 thou at a glance). What's the aim of the offset? Does it make the valves rotate? I presume there must be some advantage, because I can see the disadvantage of increased lifter wear and it must be worth the trade.Would the randomly offset rockers on my listeroid have the same effect?
   Come on guys (and Guy!) I need to be educated :)

Cheers,

Brian

I'm not a concrete expert, but what's the advantage of using form ply as shown in the photo?(or do I need glasses?) I thought the idea was to fill the hole with concrete and steel and have it "key" into the dirt.This is a genuine question cos' i've got to pour the block for another motor (1936 and better than a lister ;D ;D

cheers ,

Not trying to throw a spanner in anyones's works but there seem to be other forces at work in valve setups.
I've got a Lister L with the same( OK, similar) valve train as a CS as far as the lifters. After that, it's a side valve petrol motor. There are no rockers to generate side forces, and no lubrication at all for the iron valve guides.Ok, I know the motor is 82 years old, and you would expect the guides to be knackered,  but both inlet and exhaust had worn almost exclusively on the cylinder side.The only thing that I can see that could generate side thrust is the spring being a bit wobbly. what are the chances of both being fitted to generate the same wear ?
Do other side valvers do the same?

Dunno what happened there!Think I pressed enter for a new line and off she went!???. Anyway...

Hotater,
          Thanks for the reply.I had intended to take a load of photo's anyway, so I'll post some when I learn how. ;)
          Struck me after writing that last post that Rumsfeld's Law (as in the world's favourite diplomat ;D) may apply here. You know, the one about unknowns which we don't know etc. I suppose the list of questions will grow rapidly once we have  some basic questions. If we hadn't counted the head bolts,imagine how many surprises we could be in for from the (less visible) internals!

Cheers,

Brian

One of the problems encountered on this forum is the lack of BOTH engines to compare.  Those with originals are hesitant to strip it down to the iron to take pictures and those of us with 'Roids  *have* to strip them down to clean them.   *We look at our 'roids and wonder what's different and ya'll look at your Listers and wonder why there's a problem.   Wink

I did offer with my 12/2 powerline and 10/2 lister(See 12/2 comparison thread.)No one seemed interested.What's going on ? ??? I'll probably start on the 10/2 next week.What would you like to compare?

Cheers

God knows how many old engines are still going around on gaskets I've cut out of cornflake packet or cigarette carton or pirelli calendar, if the faces are good that;s all it needs, if the faces aren't good then dress the bloody things up until they are.

never worried about the faces on a pirelli calendar before.Does lipstick make 'em seal better? ;D ;D

cheers,

The South Africans are pretty well up on "oil from coal" technology.When I lived there in the mid 80's all of Johannesburg's petrol came from the SASOL plant. The firm still exists, but I'm not sure whether they retained the capability after sanctions ended.Wasn't the best quality fuel at the time but adequate for most vehicles.

Listeroid Engines / Re: 12/2 comparisons
« on: July 17, 2006, 01:09:56 AM »
     Whats up Guy,frightened I might find something we don't like? ;D ;D. Don't worry, if the crank's knackered, I won't hold it against the factory. If the flywheels are completely different weights (or porous!) I'll let you know!
     This  is an ex Government unit that was used to fill water tankers for road building in western Queensland, presumably from the nearest waterhole. I'm guessing that it only had intermittent use and probably spent much of it's life running below a decent temperature.On the other hand it probably did receive a bit of maintenance and genuine parts.
     It appears to have copper base gaskets fitted . Was that standard? I'll certainly have more questions once I get round to pulling it apart.

Cheers,

Brian

Listeroid Engines / 12/2 comparisons
« on: July 16, 2006, 10:31:48 AM »
     I bought a Powerline 12/2 a while ago, and in general I'm pretty happy with it. I didn't pull the (plain) mains or pistons on the initial cleanup but everything appears fine so far.You know what it's like though, that voice that haunts you saying "should've done the proper job...", well now I may have the chance to right the wrong.I now have a backup for the listeroid in the form of a genuine 10/2 Lister of around 1940 vintage. As the Dursley product is going to get a thorough going over before taking over from the indian version, strikes me that I have an opportunity for a pretty detailed comparison.
     Stop me if this has been done before, but I'm sure some of you guys will have some questions that I may be able to answer. One thing that springs to mind is the balance factor.A friend of mine has been itching to get the crank and flywheels onto his dynamic balancer since he first saw the listeroid.As well as the odd pro stock crank that passes over his machine, he has done a number of vintage jobs such as model T's and a straight 8 Hudson (from memory). The owners report a much better feel to the motors and even possibly a power increase which they attribute to the motor not "fighting itself" due to crank flexing etc. I'm not qualified to judge this, but I would imagine their bearings will last longer if everything is balanced. Even if we don't improve things we can at least accurately measure  the balance factor and compare rod weights etc.
    I'm certainly up to measuring the actual compression ratios, and have access to some pretty good measuring gear. I know that the motor is around 65 years old, but I'm sure we can draw some conclusions about how good Mr Lister was.Metallurgy is a bit beyond me, but I know where there is a hardness tester and someone who knows how to use it.What else would you guys like to know?
     I'm not out to dethrone anyones deities here, and feel free to question my measurements, but I (we) have to give it a try, dont we? BTW,they don't call me snail for nuthin', this may take some time!

Cheers,

Brian
