Lenar owner here with a question

[Greygoose]

Hi everyone-
Great site by the looks of things-thanks for having me! Anyway,just wondering if anyone knows if I have a seperate oil supply for my injection pump.It has a fill opening,the manual says nothing about changing the oil in it though-only the engine oil.Machine is 2005 Lenar 254II.Thanks very much,
Mike

I do not believe your Lenar has a self-oiling fuel delivery system. The fact that you mention a fill hole reinforces that thought. Look for possible drain plugs (a) on the bottom, (b) on the side, (c) both. Once we know your pump, we can go from there.

Thanks Greg-no dipstick,just a fill hole.

If it has a oil fill on the pump it has its own oil reservoir. There should be a drain plug on it.

I have a Mahindra 2525 which is based on the Lenar 254 with a lot of changes. I think you got the NJ385 engine which is now the mother for the Mahindra engine called IL316IDAH.
Dont know if they have made some changes on the inj pump. (in my manual it says to contact Bosch or Mahindra for calibration).On my 2525 I got a oil fill, dip stick and drain plug. But took some time to find the drain plug. Its a small 10mm hex located straight above the oil filter under the pump. Very close to the engine block.
So you need hands size of a infant or patients like a rock when unscrewing it.

Here is the only picture I got of my inj.pump.

Looks like the same engine-I do have the NJ385B.I also have that same orange cap on the top of the pump.You cannot see any oil in it when you remove the cap-how much is supposed to be in there?And what type?Thanks again,

Maybe it has a side drain plug somewhere on the pump housing. A side drain could be used to set the internal oil level. Ie: remove side drain and add oil thru filler till oil comes out the side drain...

If you have more than two hoses going to the fuel injection pump body (not counting the lift pump), you have an engine-oiled pump. One of the hoses will go to the oil gallery on the side of the engine block. You may, or may not, still have a vent, drain plug, and dipstick.

I think it must be engine-oil lubed.I took the fill cap off on the top of the engine (the one on the valve cover) and blew some compressed air into it.The air came out the orange fill cap down on the front of the pump,so the passage is direct into the crankcase.Agree?

The orange cap you see in the picture is the fill point for the engine oil. The fill point on my inj pump is on the top of the pump.

See picture with call outs.

Maybe this will help > http://www.mahindrafrance.com/mahindra254.pdf

Look at page 31

I use the same type of oil as in the engine as stated in the books. Texaco Ursa Super TD 15W-40.
