3/1 CS Restoration

[PeteDV]

Hi all. Brand new member here who is finally getting around to restoring the Lister 3/1 I picked up back in early 2019. The poor old thing had been sitting out in the weather with hundreds of other bits of machinery at a property in Bookham, NSW, Australia.

So far I have pulled the motor down completely, and there is some good, and a fair bit of bad. There was no piston, but it'll need a rebore anyway so that doesn't matter. The crank needs to go 20 thou under, main journals are fine. The head, cylinder, and block are all good and crack free. Curiously though, the valve seats are apparently done for yet the valves look ace. So I need to source some new seats.

I have just ordered a ton of new parts from our QLD purveyor of Lister goodies (Old Timer Engines) and they should be here in a few days.

BTW, I am not sure of the build date for this motor. I tried to understand the logic behind the serial number, but I failed. I *think* it might be about 1935 but I'm not sure.

Cheers,
Pete

Hi Pete,

No, you didn't fail - that is indeed a 1935 motor - quite an early one too! The first S/N built in 1935 was 13902 - and the last was 18344 (i.e. 4,442 engines in total). Yours would be the 77th built that year, which would likely mean it was built towards the end of the 1st week of January of that year!

Yes, Old Timer Engines is A1 plus. I just wish his business was not in Au. Between exchange rates and shipping parts get quite expensive, not his fault of course!

Thanks for verifying that, much appreciated.

Yes, she's an early 3-1 alright. I can see the design of the head is different in details such as the shape of the port into the pre-chamber, the injector being exposed to jacket water, and the 2.25" rod journal.

BTW, do you have a Dutch surname? I suspect it is the same as mine.

Shipping out of Aus is stupidly expensive and I have no idea why. There is also a seller in the UK, but that may not be much better.

Nope! Mine's about as British as they come - Vickers (originating from being servants to the Vicar; more recently known for tanks, guns and aircraft...)

Ah, well, nowhere close to de Vries then! 

I got a big box of goodies today. Piston, bearings, pipes, injector, pump, and about 20 other odds and sods.

I decided I'd give electro rust removal a go, and I have to say, it works like a champ!

[PeteDV]

A pic of the old and the new. The injector exposed to water does not have a wonderful life. I am guessing that, being a 1935 motor, the injector being hot in the water jacket was seen as an advantage for vege oil or WMO? Good diesel fuel was hard to come by? A hot injector meant a better atomisation?

The new injector needs a collar made for it, so I'm told. It appears to me that this is to give the Oring something to sit on. 25mm ID, 35mm OD, and 5mm thick is what I came up with.

Q - There is an adjustment bolt that appears to press against the side of the fuel pump tappet. I can't find any instruction on this and fail to see any logic behind it. Thoughts?

[PeteDV]

Collar done.

Yes those wet injectors take a beating for sure. The water wasn't to heat them, it was to cool them, later found to be unnecessary as the injector is cooled via contact with the sealing washer.

Ah, yes that makes sense. The nozzle is exposed to the combustion and would get very hot.

Who can tell me about the function of this device?

Looks like maybe a water pump cover? Although it's hard to tell from the closeup - doesn't look like anything I've seen on a single. Where did it come from, on the engine?

It is screwed into the side of the injection pump timing cover. It would appear to impinge upon the fuel pump tappet, if screwed in far enough.

It keeps the fuel pump tappet from rotating so that the roller stays properly aligned on the cam lobe.

Ah, of course it is! I should have known.

Thanks!
