Gratuitous Clean Case Shot
 
Not really re-build related well kind of.... just spent last 4 hours cleaning up internals of the cases it is so satisfying to see something thats 28 years old looking so good...

Looking very nice Davy. I never get tired of seeing how nicely these clean up.

Regards,

Great job Davy!

Ready to assemble so it seems.
The case was repairable then?

Thanks guys especially Geronimo sorry about before. Yes the case came back looking great all within spec and they made a great job re-sleeving #2.

Nice job Davy, you can eat off that thing!
My case was just like your's a few months ago, not as clean, but pretty close.
Here's were I'm at now, minus the fuel injection, recently installed.

Leakproof.

Looking good Leakproof. I will be a while before I get to that stage. Saving for parts and shipping time means I will be off the road until about September. I am however going to keep a blog of progress

Wow:eek::eek: That turned out nicely!! Glad to see the case could be saved.

What did you use to get the inside this clean?? Just brake cleaner and a cloth??
Somehow I just don't see me getting my case as spotless as yours.

(no need to apologize, I overreacted too. I guess we both needed a deep breath and a 10 second time out before hitting the keyboard. ;))

Thanks Geronimo yes the machine shop made a great job on that. As far as cleaning goes after soaking with a water based engine cleaner I hit it with the steam cleaner set as high as it would go. I then hit the bearing webs with some super fine polish and the dremel with some cotton cleaning wheels. 1800 grit paper on the case seal areas. After that about 4 hours with the carb cleaner and lint free cloths. All in all about 6-8 hours cleaning the internals, took a cleaning kit for a 12 gauge and hit all the internal oil lines where the case through bolts are located. Blew through every oil passage I could find and the piston squirters.
I may be a bit anal about cleaning but after years of running and maintaining hydraulic downhole valves in the oil and gas industry I got to know that cleaning and prep work are more than half the battle. Never had a valve fail on me even at 18,000ft and 6,000 psi at 230 deg F. ;)
