JP3 Engine Oil Volume

[steve.sharratt]

Hi All,

 

I have both the Lister parts book and Instruction manual but be b*ggered if I can find any reference to how much oil a JP3 takes. I want to order to oil but don’t know how much I need.  Does anyone know?

If it's dry sumped then that will depend on the size of the tank.

But as long as you have enough, it doesn't really matter.

If it’s dry sump with the lister copper/brass tank I’d day around 42 litres. My JP2M is 38 litres ish. And you need to allow for a bigger sump length…it might be dry sumped but there’s a gallon or more of oil still in it.

Apologies for the slow response.  I have a wet sump.  I have ordered 20 litres and will see how I go.

I have a wet sump JP2. I put about 12 litres in.Make sure you don't put too much in so that the crank touches the oil.

Cheers.  I just got my oil delivery so good timing!  I ordered 20 litres so should be good.

I converted mine from dry to wet sump, as I didn't have an oil tank. I just poured the oil through the opening created when I took the side door off until it was at an appropriate level. I had already made a dipstick, so I marked it at 1, 2 and 3 gallon levels for checking purposes. Initially I put in 3 gallons, but as I put a squirt of oil on the valve gear every day, I now fill to 2/12 gallons and the daily squirt from the oil can gradually tops up the sump.

What oil are you using?  I used to use Morris's, but I now have a paper oil filter in the sump so that I can use cheap ( well, not really, perhaps cheap-er) Halfords 20-50.

It’s Morris SAE20.  I do plan to take off the side door.  Does it have a gasket or just use cement?  I have been have some oil issues through the exhaust and I suspect overfilling so I will be watching that closely.

[monkeyhanger]

It should have a gasket.---if you can get one! Be VERY careful removing the side door and you may not damage it.  I bought a roll of gasket paper and make all my own.
