I have an AgPro (Jinma) 354 which has lost all oil pressure. Bought it used, I'm guessing it was made in about 2006. It has the Y485T engine with what appears to be an old-style oil sump. It has 205 hours.
The engine often seemed to have low oil pressure when hot, but it finally lost pressure altogether. It was running fine; when I noticed the pressure problem I shut it off and haven't started it since. It cranks fine, though.
I removed the oil pressure sensor and the filter housing. No oil flows out either opening while cranking.
I'm assuming the problem is the pump and that I need to drop the oil sump to get to it. Thing is, I can't figure out how to remove the sump. Circle G carries the sump I have. Here's a link to the item: Y485T-2-01701. This sump has 8 bolts along each side and 4 in the front. In addition, the engine mount, hydro divider and front steering hydro lines all bolt to the side of the sump. I've removed all 20 retaining bolts along with the 6 bolts on each side. But the thing won't budge.
Any ideas how I drop this darned thing? And while we're at it, the drive shaft runs right underneath this thing. Does that have to be removed to drop the sump? If so, what's the best way to do that?
Thanks!
