D6 Steering Clutch

[SHORTORDER]

My D6 steering clutch is leaking oil and I would like to replace the oil seals. In a manual they call for using a oil seal retainer tool to remove the oil seal retainer. The manual states to use (oil retained removal tool) part number (8B2893). The picture of the tool in the manual is not very good. Is this a tool that a person can make and if so, how would you go about it. Would you also use the same tool to replace the oil seal. If you can not tell, I really have no ideal where I'm heading with this project. I can use any help that can be provided. Sometime these manuals, assume a person has a lot more knowledge then they do, thanks for your time.

By tracking down that tool number you are referring to the hydraulic booster for the steering clutches. That is probably one of the poorest described tasks in the Cat manuals. What they don't tell you is that the seal holders are pinned in place and these pins have to be drilled out before the puller can do it's task.

You can make your own puller....the threads you are connecting to are 7/8 - 14tpi.

Clean the paint off and look for the pins, one on each side just ahead of the threaded plug......not the rear pins that retain the seat that you don't have to mess with. The pins only go part way in to the seal holders. You can see the pin hole locations in the picture of the home made puller.

Here's a couple of pictures to help out.

Old Magnet, thanks for the come back. I was searching this site last night and found a post from last year by King of Obsolete on how too remove the steering boost seals. If I read, right you agreed with how it was done. My next question was how do you remove the retainer pins but it is covered in the post by King of Obsolete. Thanks again for your help and feel free to add any additional information that might help.

Try searching the BB for posts by "yellercat" as well. I believe that is where the pictures I posted came from. Those seal retainers are aluminum so go easy on the drilling and thread engagement.

As I recall when I did this, the 'pins' that you have to drill out are not very long - with a sharp drill, you won't have to drill very long until you are through them. Once the type of metal changes, it would be best to stop, or there'll be an extra hole in the retainers....

The retainers themselves were a real bear to get out. They fought me every step of the way - it took lots of penetrating oil and sweat to get them out. You need the threaded rod, like in the pic, and you also need a nut, as the retainer has MALE threads. I had to grind the 'corners' off of the nut to make it fit down the hole, and the nut has to be welded fast to the rod to keep it from spinning......

So, all you need - the treaded rod, a few nuts, and a couple flat washers. And that's the tool....
