jinma

Greetings. My Jinma 254 overheated from a failed water pump and warped the head. My mechanic sourced new exhaust valves, seats and seals and new nozzles for the fuel injectors and shaved the head flat. What they need is the opening pressure required to ensure the new nozzles are set correctly...

I just bought an 06 Jinma 454. I have a basic knowledge of hydraulics not sure of all the parts. The question I have is that the loader is moving very slow, what are possible issues? The tractor was sitting for a while with loader off, I changed 2 of the quick connects due to rust, filled the...

2003 Jinma 184, has anyone added an exteral hydraulic filter setup. I was told that since my only had an approimately 1" rubber return line there is not path to add one. The filter inside the tank is just an empty cage, no brass filter screens. Thanks

Hi, my tractor is a Siromer 304 which I am pretty convinced is exactly the same as a Jinma 254. Hence any advice relating to either would be appreciated. The control for the rear diff lock consists of a cranked lever threaded into a "knuckle" on the actual operating shaft. It's cranked because...

I'm planning to buy a Jinma 504 4x4 tractor. Any opinions on the brand or the tractor? I have seen that there are many threads where they talk about them

Pictured below is the rod from my left side lift cylinder. On top of that, this is the third time I've done this, and I am not aware it happens until I try to lift the FEL. I was extending pretty high to dump a load of branches and tree debris on to a high pile. As all hydraulic actions on...

Received my parts order and thought a comparison between what was in my 354 and what I received would be instructive. As you can see from the photo the new one is much finer. The old filter looks like maybe 1/10” spacing. The new one is at least 3x finer. Outer dimension are similar. Maybe...

I purchased a new bed blade (anvil) for my model 6 Jinma chipper and the new blade has one beveled edge, the original has 2 flat edges. Contacted the seller and he stated to install beveled edge towards the chipper blades. Has anyone run into this before?

I thought I had read somewhere that loose wheel nuts cause a creaking noise but I can't locate that thread anymore. This has been happening for a while. Not sure when it started. I have the wheels bolted on at the widest possible setting. I tried tightening the wheel nuts but the noise...

I thought I needed a QD1332C. The nose of the starter does not fit into the bell housing of tractor. It has a lip (pic below), where the original does not. Can anyone tell me the correct part number? Thanks

While waiting for my brake parts to arrive I thought I should replace my front driveshaft boot which was quite rotted. I’ve removed the rear 13mm and front 10mm bolts which hold the driveshaft covers on but that doesn’t seem to give you any access to removing the two covers. So what are the next...

Ok, second post for the other brake unit. I thought this would go slick as I now knew what to look for. Removed the cover plate expecting the same condition as the other side but no it was a disaster. The inside looked completely filled up with crud. This was oily with maybe dirt and rust bits...

My 2005 354 brakes were always sketchy. You really had to step on them to get any response even after adjustment. Given the hilly nature where I live I decided they needed attention. The first issue was access to the side covers. This required removing the fenders and rops. No issues here just...

My rear differential does not lock. Is there an adjustment and procedure to make the adjustment. Thanks, Dave

I recently purchased a 2006 Jinma 284. Among other items I found that needed correction the wires for the clutch safety switch were hanging loose. I purchased a new switch but can't find the original switch or mounting location. If someone could provide the location where the switch should be...

I recently purchased a 2006 Jinma 284 with the old rectangular instrument cluster. The tach does not work and other gauges work intermittently. I am interested in purchasing and installing a new instrument cluster and wondered if anyone had done this and if they would share the wiring...

Circle G no longer carries the v belts for the Model 6 chipper. 😟 I have seen past forum posts about a NAPA upgrade belt, part number 25-22425. I'm guessing this is a viable option, but if you decide to match all five belts when replacing a broken one, it's a pricey proposition. NAPA online...

Hello all, I am reaching out through the forum seeking help. So here goes; I own a 2002 JINMA 224 no FEL though it does have the hydraulic line QC for one. I bought it new, may have had 2 hours showing on it. Over the years I had a few mechanical issues. Fuel line – minor problem, 3 yrs ago...

I haven't used my backhoe since last summer, connected it up and it's not moving. I've got flow into the auxiliary pump but when the RPMs are up it comes out fast but sputtering like air is getting in. I've checked the tank filter the gasket seems good, I see no cracks or obvious signs that the...

Looking at my valve to hydraulic line face seal Jinma o rings I measure these as 2x8(id) sealing o rinos. I believe a 90 Shore durometer hardness o ring is required for sealing… but maybe not. Not sure on this. So, I’m wondering if I get the 90a or is a 70a o ring ok? I assume Viton or bunta...

Anyone got a bolt on or weld on mechanical thumb (non hydraulic) on their jinma JW-03 backhoe? I would like to know if there is one ready made to suit or wether you made one and your experiences/advice.

Can you find parts for Jinma tractors?? Are they too big of a risk? Thanks

Good morning, I am new to this forum, I own a Jinma 284, we rebuilt the motor. Now the shifter became disengaged, (shifter flops around) it appears the attachment pin has broken. Can anyone give me some guidance on removing the bearbox cover so I can replace/insert a new pin? Thank you in...

It is a 304B by nortrac with T395E engine. I recently refilled my lift hydraulics and it seems to have leaked hydraulic fluid into the oil enough to blow the dipstick out under pressure with the engine running away and blowing oil and smoke. Hydraulic fluid was almost completely gone after...

In measuring my Jinma Chinese LW 8 backhoe hydraulic parts in order to find replacement seals I’m wondering where I place the slop of the measurements. For example, gland nut o rings. I get 64.5 mm ID on the part and 70.15mm for the cylinder wall id. So would a 64mm I’d x 4mm t work? Similar...

I’ve been trying to remove the gland nut off my 2005 Jinma 354 backhoe which is a LW8. Haven’t had much success yet so I’m hoping someone can point me in the right direction. I did buy a gland nut wrench but the inserts are for a pin type and I wasn’t able to find a Jinma style one. I did modify...

So this may be something someone might be able to point me to the right folks on finding parts on the BH 7600 Korean backhoe. I am leaking fluid from one of the Hydraulic level control plungers. Need to find a repair kit for a new upper o-ring and upper white flat plastic washer. I am pretty...

I have a couple of issues going on with my Jinma and starting. 1. It's been really difficult to start. I noticed I had a leak at the valve of my sediment bulb, so I replaced that and no more leak. In getting it going again, had my wife constantly hit the primary bulb and it eventually got...

Need replacement front turf tires for Jinma 284 tractor. 26 x 7.5 -12. Anyone know where I can find 2 replacements. They have dry rotted badly and one

Hi folks, I am changing fluids at 50hrs. Front axle no problem 80/90w Engine 10w40 Rear axle expeled like 21lts of what I think is gear oil.(is this right?) Rear axle, transmission and transfer are all together?? and do they use 80-90W gear oil. Can´t find drain plug for tractor hydraulics at...

Dear Forum, My Jinma is basically dead. I get nothing. No lights, no start. The battery tests at 12.6 volts. I get the same voltage reading at the main fuse supply side. The battery is five months old I just replaced the iginition switch because I had panel light issues before and that...

Dear Forum, My Jinma has basically no electrical power. The battery tests at 12.64 volts. The same voltage reading to the 30 amp main fuse. I had trouble with dash lights before so I replaced the ignition switch (being careful to replace one terminal at a time onto the new switch). Didn't...

Hi all, I have a Jinma 284 chinese tractor and am having an issue with the relief valve. I was working on the hydraulics and removed the 4 bolts that hold the needle valve in on the bottom side of the loader valve assembly. Everything in Yellow in the photo fell out, and when I put it back in...

Hello everyone, first post here. So if I'm in the wrong spot forgive me. Alright full on back story. I inherited a tractor from my grandfather. The body says Aggracat 254. The engine, model and sticker on roll cage says Jinma. I've done history research to find all the different brands for the...
