Never got a response to my questions, this forum is dead is seems, wish I could get a refund now that I know this. Live and learn.
I think the clutch adjustments are the same for the 300 series tractors.
Tractor: 2007 Jinma 254XL with FEL
Engine: Y385
Transmision: HI/LO 6 speed with shuttle shiftI am looking to adjust my clutch also, specifically the pto portion but wanted to understand the entire process. It seems the procedure is flawed for the primary clutch. The gap between the release bearing and finger is meaningless as the bearing travels along the primary shaft. A specific tolerance at the jam nut area seems to be more proper. Any thoughts?
Also, is the pto adjustment made with the clutch depressed?

Transmision: HI/LO 6 speed with shuttle shiftI received my parts, gasket kits and bearing set, but have a question regarding the torque spec for the connecting rod bolts. It seems that the Y85 service manual states it to be 88ft-lbs but the bolt size indicates it should be around 47ft-lbs.
Any thoughts?

I pulled the pan and checked the rod bearings. Did you look at the pictures of them from two posts ago? They have some damage to them and now I am concerned with the mains. The oil pressure has always been @ 0.4Mpa or 60psi everytime I have run the tractor.

I like to fix and take care of my things. Probably break it apart this weekend and check out the rest. It will also be good to check everything out like the clutch and other fasteners that aren’t accessible.

Transmision: HI/LO 6 speed with shuttle shiftWell I pulled it apart last night. Some interesting results that I believe are due to poor assembly or crap in the oil. It was a pain in the ass to get pictures in there and they dont really show what I think they look like. I have seen worse and those engines have run a very long time without service but I think I will do a bearing replacement. It looks like I will split the tractor so I can also do the mains as I cannot get to them to inspect them at this point.
What are your thought after looking at the pictures?

Transmision: HI/LO 6 speed with shuttle shiftThanks, I like this idea for the engine heater. Is that pump convection or circulation?

Transmision: HI/LO 6 speed with shuttle shiftFunny that you mention this, I was just looking at these last night. I plan to pick one up.

Just to be sure my understanding is correct this is how I believe these systems are setup. Not a hydraulic guy and my last experience was in a college class 25 years ago. I cannot seem to find a schematic of the hydraulics system. The pump on these tractors is driven by the engine. The pump is supplied from a tank reservoir in the rear casing of the tractor and returned to that same reservoir. After the pump the system piped into a valve and from this valve the components are fed. The hoses from the valve need to “recirculate” the fluid or it may be bad juju to the pump as the pressure would build and have no place to go. Hence if a hose failed it would be bad.
A relief valve on output hose would at least save the pump?
Am I far off on this one?
