I have two 3-point piston seal kits that I purchased from China. Both have more o-rings in the kit then I see installed on my tractor. Both have different sized o-rings that what is listed in the parts list for a Jinma 284 as well. My china supplier tells me the first kit is what he had in stock and the second kit is what Jinma sent him when he ordered the kit directly from them.
Assuming the kit from Jinma was the correct one I compared it with pictures of kits that domestic suppliers have up on their WEB sites, and each one looks different than the Jinma kit and different from each other! All the kits, domestic and Chinese have more parts than what then what is listed in the factory parts book too!
I have to imagine that the size of these o-rings is important so they should match the sizes listed in the parts book, and even though it can be hard to measure o-rings it痴 obvious that what I have (especially for the piston) is way off. The white washers for the piston are not cut so how do I get them on. On the domestic suppliers WEB site they are slit in 50% of the pictures. My supplier in China says 笛ust cut them? Are domestic suppliers cutting them for their customers or do I have the wrong part??
Moreover I have to believe that given the cost conscience nature of everyone these days I cannot see anyone, Chinese or domestic, supplying me with extra parts just for the heck of it.
So what gives? Is there a secret decoder ring somewhere? What are the sizes of these o-rings supposed to be? How many should be in the kit? Do people cut the white spacers or do they arrive cut in most cases? I realize there were several different designs for the lift over the years but my kit does not match any of the styles as described in the parts book so that can't explain all of this confusion!
