oil pan removal

[Texan4Life]

hmm thats so odd. sounds like a plug or re stricter isn't in place. or like bob mentioned maybe something wrong with the gauge or something blocking the flow to the gauge. cuz if you have good flow out of the port it should have enough volume to build pressure. sounds like the oil is going somewhere it shouldnt maybe

 

[Bob Rooks]

Yes got a good flow. I am going to see if I can make a short video showing the oil flow coming out of the port and post it.

That would be great. I hope it shows it shooting out. Did you try blocking the flow with your thumb? Never mind.

That's what I was thinking originally with the pump's pressure relief stuck partially open, but apparently this pump doesn't have one.

Max, why don't you remove the spring and valve poppet from the filter head to make sure it isn't stuck, or if the spring isn't broken.

Ok I will give that a try. I took a video of the engine running with the mechanical gauge installed then removed the gauge to show the oil flow out the sending unit connection but can’t seem to get uploaded to my reply but will keep trying. Thanks

 

[Duramax88]

Ok took out the spring and poppet and still no change

If your getting oil out of the block where the mech gauge is connected you would have to have some movement out of the gauge ? Something

and if your getting oil to the top of the engine you have pressure ?

I assume Thomas showed you the video I sent him. I may be getting 1 pound of pressure on the mechanical gauge but that is it. I drove it around the yard for a little bit with the valve cover removed and I had some oil (not a lot but some) spitting up on me and the tractor. I am at a loss as to what to do next. The motor runs smooth, doesn't smoke much and I let it run for an hour with no problems. I have a gentleman who wants to by the tractor but I wouldn't want to sell it to him and it not be running right. Is it safe to sell it the way it is? Any suggestions would be greatly appreciated

IF, the pump is GOOD (shaft keyway and internal wear), the oil MUST go somewhere.
The pressure come from restriction of the little clearance between crankshaft, camshaft and rocker arm, bearings and bushing.
You can check your mechanical gauge by connecting to an air compressor. Both gauges should show "almost" the same.

I would NEED to get that oil pump in my hands before driving it around with 1lb of pressure. Also, I would have a hard time sleeping not knowing what the main and rod journals look like.

Ok I needed to hear that. Now I need to find a service dealer as close to me as I can. This work is starting to get well above my knowledge. I live in Northeast Ohio if anyone knows of a reputable dealer please let me know. Thanks

 

[Duramax88]

Ok I have been off for awhile so I will update you folks on What I am going to do. No luck with anything I've tried so I am throwing in the towel before I invest any more time. I am going to find a service center that deals in Jinma tractors to get them to fix the tractor before any more harm is done to the engine. I will keep you posted on what is found out to be the trouble.

Looked at the engine and found the JD stamp behind the injection pump. Under the manifold I found numbers stamped into the block but no tag (engine has been rebuilt with new block installed). Numbers look to read - 20111008.

A-HA! Who rebuilt the engine?

If you know who it is you should ask him about it. Methinks there's the rub.

 

[Duramax88]

What do you mean there's a rub? My mechanical terminology and knowledge is limited. Thanks

i think he just means that could be the issue. Maybe the rebuilder missed something.

Yep. A quote from Hamlet. Literal translation - "That's where the problem could lie". Really has nothing to do with mechanics or engineering. Didn't mean to confuse.

 

[quicksandfarmer]

Forgive me if this has been brought up already, but has the engine had oil pressure at any time since the rebuild?

Based on your description, it sounds like the oil pump itself is fine, but that an oil passage is open somewhere which is keeping any oil pressure from building. That's not good because it means oil isn't getting everywhere in the engine.

Hello everyone, back again. Thought I would give an update about my tractor. Last week I took my tractor from where I live in Northeast Ohio down to Chesapeake , Va and dropped it off at Ranch Hand Supply for Ronald to find out why I am not getting oil pressure. Talked with Ronald for about a hour and a half explaining what had been done to the tractor to date. I am waiting for him to get back to me after he investigates the issue. When I get an answer I will give another update. Thanks to everyone who has tried to help me with this issue. I am pretty anxious to find out what is wrong.

Me too. Glad you're following up, seems that only the good ones do. :thumbsup: :thumbsup:
