Well, I've just recently gotten over my crankwalked engine. Here are some pictures of the thrust bearings removed from the engine.
The same 7bolt motor is in. The gaskets on the block have been replaced along with the rod bearings and main bearings. A Concept Racing Crank alignment kit has been installed along with ARP main studs.
Here is an excerpt from the instructions that came with the Concept Racing kit that I thought was quite funny, and true. I thought maybe I should send it to Mitsu headquarters / a couple of service departments, but I did not want to make anybody mad.
From the Concept Racing Instructions:
"The holes that Mitsubishi drilled in the main cap will all be slightly different in size. Mitsubishi's intent was to cut a hole that was 11mm in diamter. In manufacturing, acceptable tolerance for a drilled hole is .000" to .005" because of drill bit run out and wobble."
First impressions upon startup are that the engine feels a whole lot more solid than it did before.. It feels complete and solid. I can't really describe it other than that.
Also, a sidenote. I was having problems shifting gears and such with the transmission, and I immediately blamed it on crankwalk.. However, upon installing the new thrust bearings, the shifting problem is still there. Well, I have fixed numerous problems with the transmission /clutch, and it now shifts as smoothly as can be.. What I am getting at is that, I believe my case of crankwalk was caused by the extreme forces of me shifting/forcing between gears when the transmission / clutch was not disengaging properly, so it was pushing against the crank with an unecessary amount of force.. Just thought I would post my experience / thoughts on this subject now that I have experience..
I will post again in 500 miles when I drop the oil pan and check crank endplay again.
