Hi, I think that after having my machine apart for over 2 years, I have misplaced the proper connection of the steering hoses. I have one hydraulic pump. The steering box has two ports facing out the right side and two ports facing left. The left ones go to the steering cylinder. The two...

These are the protrusion measurements. I didnt bolt them down - just tapped them down to make sure seated fully. Used a dial indicator and measured each place several times. My dial is 100 thou range so not ideal - .5 thou is best I can read off it. Nothing alarming here though. I would...

In the photos, I am measuring directly the old one and taking scaled measures off a photo for the new one. The old one has the smaller diameter edge that amounts to 0.718cc. That is what had me thinking the compression might be higher with the new one. With a stroke of 90mm, the 85mm new...

Heres what it looks like. You can see the start of water pitting in the #3 & #4 cylinders. It looks worse in the photo than it is. The injector inserts are very hard steel. Much harder than the head. These are dry liners and brand new. They did measure identical to the old ones. I...

I have a 2007 Yangdong Y485. Head gasket will not seal. I have compression in the water. I measure the liner protrusion to be 36 thou above the deck. All liners are in plane with each other. The deck is flat. The head surface is flat. I cannot find a spec for this engine ( Cat and Perkins...

It has been 2 years since this machine broke as discussed in a previous thread : Jinma 354 white smoke no power won't rev past 800rpm Recap: Cam thrust plate bolt came out and went through the timing gears, busting case and hydraulic driver. Repaired but did not change cam bearings. Decided...

So I am moving forward slowly. I quit overthinking this and towed it to a flat spot, dropped the loader and split it. I blocked the back half stationary and only moved the front with two scaffold planks and a 3 ton floor jack. Clutch, flywheel and flywheel cover were bolted on correctly...

Update: I have pulled the head. I didn't find an obvious head gasket problem but there was a surprise. I found a piece of wire jambed in a water passage between #2 and #3. It appears to have been stuck between the cylinder insert and the gasket. One end rusty and the other carboned black...

Update : Received new cam and bearings. Removed head. I did not find an obvious blown head gasket. There was a surprise though, a chunk of wire bent at 90 degrees stuck in a water passage between cylinder 2 and 3. i was careful to lift head straight up so I dont think i bent this but the...

Having just gone through several attempts to repair my hydraulic pump by cannibalizing several pumps, I found this video helpful. HYDRAULIC GEAR PUMPS EXPLAINED! - YouTube

Jinma 354. 4 cylinder. 350 hours. Ran for about an hour and all was smooth and normal. Running 1400rpm at normal temperature. I was working the hoe so had back to engine when noticed sudden lack of hydraulic power as engine sound changed. Turned around to see white smoke and revs dropped to...

I'm losing confidence in the hydraulic shop that treats me like an idiot when I ask them questions and try to spend my money there. I had taken it to my local hydraulic shop and placed the piston and body on the counter and it was their 'expert' that sold me O rings. After two hours of...

Jinma 354 with one hydraulic pump system. After several go-arounds with replacing the hydraulic pump and installing a pressure relief bypass into the system, I have no power steering. Observations with front wheels off the ground: It takes 4 full turns of the steering wheel to move wheels...

About 2 years ago I put in a new E320 pump in my 2006 354. Worked great - big difference. Last fall, I put my backhoe on for the first time in a couple of years. Tried pushing a 2'X2'X1' concrete block away from the tractor with the dipper motion. Instant shower of oil all over everything as...

Quicksandfarmer, Thanks so much for taking the time to respond. Your comments confirmed the line of thought I was on and I think I have solved the problem. I read your comments and agree with you that I have not damaged the cylinder. That also confirms my earlier thought that the cylinder...

I am experiencing a problem with 3pth not lifting. This is the second time it has happened and want to focus on what I believe is the common cause. Last summer I drove over a pile of top soil to rip the sod layer off it with a box blade. As I drove down the steep slope, the box blade hung up...

Hi all, I've spent far too much time pulling wrenches lately and I'm not sure I'm getting any closer. After changing timing gear case and pump driver I decided to do the recommended head retorque and valve lash adjustment. Never done it and machine has maybe 300 hours on it (guessing as the...

After much procrastination, I finally tackled the repair of the broken timing gear case. Thanks to those who responded with helpful advice. One must tear a lot of things apart to do this repair! I was afraid of getting the timing out of whack so took lots of photos as I tore things apart. I...

A few weeks ago I posted about problems with my Jinma 354 with 485 engine. I had partially disassembled it and ordered parts. Got parts and tried to remove the old timing case. I have removed radiator, hydraulic pump, injection pump, and many other assorted parts to get room to work. It...

I was pushing dirt with the bucket when I thought I heard a metallic click and the motor pitch changed slightly. I idled down and tried to determine if the motor was in fact knocking slightly. Then I noticed oil pouring out the front right side. Shut it down and saw that the timing gear case...

My Jinma 354 has survived 6 Alberta winters outside with infrequent use. I have never charged the battery and although it is a bear to start in -25C it has always cranked long enough to fire. The charge light was intermittant for the first few years. I tensioned the belt and checked all...

I have searched the web for some parts but have not found all of them. For a '06 Jinma 354, I need : Rubber boot for steering cylinder Sway link limiter (turn buckle and chain thingey on the lower arms of 3pth) Headlight bulbs (all of them) Rubber air hose Glow plugs New Seat For the Koyker...

I have a 6 year old Jinma 354 with Koyker 160 FEL. Outfit has maybe 200 hours on it (cant tell as the hour clock has never turned a second since brand new). I have only used it maybe 4 hours in the last 9 months. Fired it up last week and found two hoses on FEL sun cracked and leaking...

Hi, I have had my Jinma 354 for 6 years and only used it maybe 300 hours. I am wondering if the 3pt hitch is normal. My observations: It is up or down, I can't stop it at a desired height (this would really help smoothing dirt with the box blade) If it is down, it floats. This sucks when...
