Thank you! My question is where can I purchase the metric quick connects so I can mount the pump and hoses before attaching the backhoe?
Four wheel drive on my Jinma 354 has stopped working. Cannot move the 2WD/4WD lever all the way into the 4WD position, just almost. Took it apart but found no obvious problem. Then I slid the cover to take a look at the drive train near the front axle. Does not look “right” to me especially when compared to the photo on this thread. Any advice?
Took a look at the front axle connection for my Jinma 354 front wheel drive. Does not look right to me, but do not know how it is supposed to look. Advice? Here are a couple of views:
I have yet to get beyond the front drive fork release assembly. Looks like the steel ball and locking spring are missing. Because they are missing I do not know what holds them in. Do you have the parts (ball bearing GB T308-1989, and spring 160.37.148)? The parts are listed in my parts listing that came with the tractor. See photos.
Okay. I pulled the plate with the release fork assembly. See photos below. Although I do not see anything obviously wrong, the fork will not slide back and forth laterally, seems to be jammed. I removed the lever and the shaft release fork head to free up the fork, but it does not move.
The diagram that came with the tractor is not exactly the same in that it has two pins to position the plate rather than a clip. The lever has a roll pin.
Will look more closely to see why the fork seems to be jammed.
Thanks. I will take a look at the front driveline. Will the driveline rotate even if the 4wd lever will not engage?
Thank you. I will take a look at that as soon as I can. Got the tractor back into the barn after a couple of days of slipping and sliding in 2wd, backing up 90′ into the barn. Started to remove the cover plate in the field, but discovered that the floor of the tractor is also attached. Did not see the bolt that secures the metal grid, because of the snow and ice. The tractor will be out of use until I can get 4wd working. Right now, we are dealing with the aftermath of a 38″ snowfall. Keeping me busy digging out and taking care of our farm animals without a tractor.
Got the head back from the machine shop; they milled off one ten-thousandth of an inch. It has been cleaned and pressure tested.
The order of head bolt tightening is to start with the two center bolts and then tighten those on each side of the middle ones moving in opposite diagonal directions until they are all tightened.
Torque specs are to tighten 137-157 Nm, that is 101-116 ft-lbs according to my Jinma Operation Manual.
Thank you. I made a decimal error; I meant 0.012. The machine shop told me 12 thousandths. Sorry about that!
Thank you, Bob, for the useful advice and photo.
We used the fuel injector port to attach the compression tester. Got the following results: Cyl 1 (nearest radiator) 459 psi
Cyl 4 (nearest bulk head) 378, 330, 319 psi
Cyl 4 was filling with water from the radiator; drained the radiator before testing. Aborted testing after finding the water.
Ordering a head gasket, head bolts, injector washers, etc. Plan to pull the head, and have it tested and milled at a machine shop.
