Rebuilt V1902

[reed2022]

I need some advice! I just purchased a V1902 that was rebuilt about 12 years ago and never run just sit in heated shop. My question, how should I go about breaking in, what oil should I use or should get some kind of breaking oil and any pre-cautions? Thanks BR

Since it has been sitting for so long, it would be a good idea to assume everything is dry. Remove the glow plugs and put a little bit of clean engine oil(ATF works too) down the cylinders and rotate the engine BY HAND for 3-4 revolutions then put the glow plugs back in. If the crankcase is full of oil, drain it and put in new oil. You will need to pre lube this engine since it has been sitting for so long, as it probably doesnt have any oil on the bearings any more. You should be able to borrow one from the auto parts store. If you have never used one, it is basicly a tank that is filled with engine oil and the tank is pressurized with air to around 50psi. A hose is hooked up to the engine (oil pressure sender port) and you force oil into the engine oil galley. They can be easily made as well. Just use the same oil you would normally use. I run new engines under a moderate to heavy load for a few hours and change the oil and filter again. After that, use the machine as normal.

Thanks Hotrod 1830 for information I will check with the local auto parts see if they have a pre Lube tank if not I will make one. Thanks br

I would PRELUDE the engine first. Run the engine until nice & warm; 30 t0 60 minutes at varying rpm often. I'd change the oil after running it. Drain the filter & cut it open so you can check for metal parts.

Thanks mmslic I do that and see if there is any metal. I'm having a hard time finding pre-lube canister with out paying $250 for one. I think I'm going to make one. Thanks br

Sitting for that long, it is possible the inujectors have stuck too, see how it runs, if it wont' start, the injectors may be stuck, hopefully not though.

Thanks Tazza, I hope not.. Would I be better off take the injectors out of my v1702 and put in the V1902. The 1702 run good before re moving to install the 1902.

You can use a fluid evacuator that has a pump out feature / selector valve. I have used to those to refill transmissions on FORD trucks & suv's that do not have a conventional dip-stick tube. Just keep it clean & rinse it out afterwards. It should help you achieve around 15 to 20 psi. That will be more than enough for an initial lubing. I'd pump in around a quart or two that way. They are made by "mity-vac" cost around $120.

I wouldn't be swapping injectors over juet yet, they may be just fine and i can't be 100% sure that the injectors between the two models are the same.
IF an injectors is indeed stuck, you can generally free them up by pulling them apart one at a time, lubing with WD40 and putting back together.

Thanks mmslic, I have evacuated pump that I used on my boat. I can clean it real good, it's 12 volt and I think it max is 50 lbs pressure.
