I have this compressor rebuild kit. JPO 500010. I believe my compressor has a leak and the desiccant needs a oven drying. My question is or can someone send me a link of the how to to use this kit for the lr3

 

You can not oven dry the desiccant and expect that to do any good. Sure, its dry. But if its factory its already broken down and needs replacement. Also these kits are more robust and include not only new dryer material but also a new end-cap because the factory ones like to crack:

This kit it specific to the Hitachi compressor:

^ The above kit is missing the connecting rod bearing and no kit that I know of includes one. Its also missing several o-rings which was really annoying... see my thread:

As for instructions, Google search is your best bet. Plenty of info out there and videos. Its really not a hard job at all, just takes time and good basic mechanical skills.
