Original Lister Cs Engines / Re: Bigger engine to replace st3 engine
« on: February 11, 2024, 07:48:10 AM »
You could replace your ST3 with either an TS3  or TR3. They will be of similar physical size to the ST. The rotation is anti clockwise when looking at the flywheel and they are both air cooled. Don't know what speed you operate at but at 2500 rpm the TS will give around an extra 10hp, and the TR around another 14 - 15hp

It should say LPWS4.
LPW = water cooled, direct injection.
LPWS = water cooled, indirect injection.
LPWT = water cooled, direct injection, turbocharged.

Lister Based Generators / Re: Lister LPWS starts once but not again!

Sounds as if the rack, or one or more of the fuel pumps is sticking. You could remove the end cover and see if anything feels tight.

Lister Based Generators / Re: How big of a gen head can a LT1 manage?
« on: September 12, 2023, 12:35:34 PM »
You have an anti clockwise LT1 engine. It was manufactured in 1980 and is a build 22. The output of the engine is speed related, so the slower you run it the Lees power it will give.

Engines / Re: What is this in the photo?

It is basically an oil operated switch. Your engine appears to be an AC2W marine engine. This switch was used to energise the charge alternator whenever the engine was started.

Engines / Re: TS2 cylinder head and top plate separation

To separate the two parts of the head you will need to remove both valve guides. Not to difficult if you have access to a press.

Engines / Re: Lister HR3 injector oddity (rubber seal)
« on: July 27, 2023, 04:11:46 AM »
It was quite common for Lister to use this type of injector at the time. As you say over a period of time they tend to shrink and harden. Back in the day they were offered as a spares item by Lister. So maybe some of the old Lister dealers may still have in stock. Or maybe an injector specialist will carry stock.

Maybe a stupid comment. But I assume you've taken both the m6 securing bolts out from behind the camshaft gear

Engines / Re: LPWS3 crankcase breather
« on: June 23, 2023, 10:27:09 AM »
This engine uses an internal breather system. If you remove the rocker covers you will see the breather tubes protruding from the cylinder head. One tube per cylinder. These tubes run through to the inlet manifold. Normally you wouldn't get any problems with them. But if you want to check there clear just poke a piece of stiff wire through them.(

Petteroids / Re: Petter ph2 fault
« on: June 19, 2023, 02:31:40 AM »
If its had a top end overhaul you need to check and ensure no one has fitted copper washers under the injectors. PH injectors fit directly onto the sleeve in the head and do not use washers under the injector. I have found this a number of times and it will cause poor starting when hand starting the engine.

Engines / Re: Lister SR1 flywheel removal
« on: June 08, 2023, 09:45:40 AM »
The SR engines were the same. As well as the tower ring the housing that holds the felt seal had course spiral machined into its internal diameter. The idea was that as the engine was spinning any oil excess would be forced into the engine. So the majority of oil should end up back in the engine before reaching the felt seal. Obviously as these engines were available in either rotation the correct seal carrier for the rotation needs to be fitted.*

Lister used to supply a special spanner which we used to call a flogging spanner. It was basically a cranked spanner which was a good fit on the flywheel nut. It was designed to be hit hard with a lump hammer. This was enough to shock the bolt and loosen it. To refit was just a reverse operation.k

Engines / Re: Engine Identification
« on: May 06, 2023, 01:18:29 AM »
At a guess I would say it's a 1964 LD1 engine.  The only thing that is a little odd is the letter Y in the number.

Original Lister Cs Engines / Re: SR2 air outlet duct
« on: April 25, 2023, 12:13:44 AM »
There was ner an original supplied by Lister. All Lister would put on the engine was the very short duct with an oblong flange to allow for the fitting of a canvas duct. The canvas duct was never supplied by Lister as every installation is different.

Original Lister Cs Engines / Re: Fuel consumption of air cooled L-P engines
« on: March 23, 2023, 04:06:32 AM »
Lister have produced many air cooled engines over the years.Most of them would be able to run at 1800 rpm with the correct governors fitted.As you say the Alpha range uses an SAE 5 housing. Also I think that the LT/LV range was also SAE 5. The T range of engines used an SAE 4 housing. The older air cooled engines such as the SR/ST May not be an SAE size as back in the day Lister worked to there own specifications and not British Standards. But not totally sure of that.
