Thanks for your reply. I've got a Jinma 284 which I think is basically the same tractor. Mine is 17 yrs. old but less than 100 hrs. I only use it to clear my lanes so it sets in the shed most of the time. Just now checking the hydraulic oil filter in the sump and, like you, found holes in the filter. At $60.00 a whack I thought I'd look for a mod or even purchasing a piece of 100 micron screen and repair the old one. The member I'm trying to contact posted a mod using an aftermarket filter that costs less than $10.00 plus shipping. I'm all about saving $30.00 or more but I need to talk with him about how he modified the old filter unit.
Thanks for the reply. According to Ron's post he was using a different strainer from the same supplier. The reason I'm trying to reach him is he stated he cut the OEM strainer off the tube and welded a 90 degree elbow, then a threaded fitting to accept the new strainer and had it laying horizontal in the bottom of the sump. The problem I'm seeing is the aftermarket strainer is 8 in. in length and I don't see it fitting horizontally in the sump. Does that sound right to you? Just checked "surplus center" and they no longer have the strainer that Ron used so now I'm looking at your setup. Did you use this in a Jinma 284 pre 2006 tractor? I don't recall you having a Jinma.
I don't have a Jinma, I have a Yuchai bulldozer. The same nylon suction strainer was used in both applications. My installation was more straightforward because the strainer goes directly into the side of the reservoir at the bottom.
That helps me make a decision. I now understand why Ron had to go horizontal with the 8 in. long filter he used since the sump on the tractor is only about 5 in. deep. I'll find an aftermarket filter that will work. You never said anything about Ron. Do you know if he's still around? He was a great source of info on this site. Thanks for all your help. You too are a great source of info here.
Never met Ron, although we were "friends" in this forum I didn't know much about him. He was always very cordial, and very knowledgeable about Jinmas and their individual components. I think he may have been a retired engineer. He lives about 40 miles from me in Port Angeles, WA. Don't know of anyone in the forum that has met him personally. Hope he is ok.
Truer words were never spoken.
I haven't finished replacing the hydraulic filter on my 2005 Jinma 284 yet BUT I did discover something that should reduce the cost. On my assembly I was able to remove the filter element only and purchase just that part. It looked like some kind of glue was used to attache the top cap to the tube. Just break that seal, remove the bolt on the lower cap and remove the old element. I haven't purchased an aftermarket element yet but don't think I'll have a problem finding one that will fit. The specs. for the element are: 100 mesh, height - 3 in. (it could go to 3 1/4 in.), diameter - 2 7/16" (this allows you to use the OEM top and bottom caps). After reassembly the unit should measure between 5 3/4 in. - 6 in. from the botton of the mounting flange to the bottom of the unit. Once I find an element to fit I'll edit this post.
