Sorry. Got wrong picture on the last post I made. Here are a couple of the welded spool. It seems to work so far. No leaks yet.

Good deal, and keep those joints lubed.

Thank you everybody for the info and help.

Jimmy;
I read your post on this forum, while searching for a supplier for replacement spools for a Dinoil Hydraulic valve body. I own a Machine shop here in Anderson, IN. A customer brought in to my shop the exact same Dinoil valve body, that you show in your posting. After learning there was no one offering replacement spools, I decided to devise a way to repair their spool without welding. I have drawings, and instructions on how to repair the spools, but don't know how to post them. It seams as though this is a constant problem, but can be easly fixed if you have access to a local machine shop. I will share them with anyone who has this problem. Jim Watters, Watters Custom Machine & Engineering, 878 N. 200 E., Anderson, IN. 46012. 765-278-4060. email watterscme@gmail.com. Thank you. Jim Watters

If you can scan them, you can post them.

I am curious how one can fix a worn spool and bore in a valve.

I would be interested in how you do this.

J. J., here is the drawing depicting the method I used to repair a Dinoil spool valve. It didn't take very long, and works very well. A lot less expensive than a new valve-body, which is all the dealer offered me.

J. J.,I had to go to the advanced page to find the attachment symbol. I'm trying it again.

Jim... If you can email me the files to me I can go ahead and attach them for you. My email address is jimmypowell@raker.com.

Thanks,

BTW the welded spool is still holding up pretty good.

I repaired a worn spool/housing back in the late 60's by having the spool built up with hard chrome and then grinding the spool lands to a slight oversize. (cylindrical grinder) Then honed the valve body for a slip fit on the spool. Probably wouldn't be cost effective given today's economy, however.
