730D Lower engine cover

Hello,

What is the cover located near the oil filter cover and the oil drain plug?

The governor on my 730D failed and spit ball bearings, cotter pin chunks and weight chunks all into the engine case. I drained the oil and got one bearing but I need to locate more of the pieces before I can comfortably put it back together. I want to take that cover off to see if I can find more pieces, but I can't find anything in the manuals that indicate what it actually is.

Thanks!

The oil pump cover.

I should have read farther. You won't access anything but the oil pump gears there. There is a screen inside the crankcase that keeps parts and junk out of the gears.

Thanks Mark, that's super helpful. How can I access that screen? One of the crankcase covers?

Working with a parts manual and an I&T manual but the illustrations don't always make sense to me.

Guess I should read the dang manual. I see the screen listed clearly there, so I'll get the pump pulled and hope I find my missing chunks. Thanks again.

You should be able to look(feel) down in the crankcase through the top covers and find your pieces. I wouldn't try to remove your pump. Won't help to find the pieces.

Remember there are oil lines running to the pump!!! You don't just drop the pump like you maybe thinking!! Like some have mentioned take the top cover off and see what you are up against first. I just cleaned out a 70 gas crankcase, drain the oil and slosh a quart or two of diesel drain and repeat. Then just try a magnet. The 70 was tight to work with and the diesels are worse(I have been told) and getting to the oil lines of the pump will be worse.

An I&T manual lacks the information and photo's that are included in the Deere service manual.
