rebuilding the ranger block

[pongorulz]

first off, let me say this is awesome jess, good idea coming up with a website geared only towards turboing rangers. smashing. now it makes things a lot easier for help since everyone on here is doin the same thing.

anyways....

im rebuilding the ranger block and in the process of buying my new bearings (rod and mains) now my question is, should i have the crank turned and the oil holes chamfered?

when i was working on the tc block i was told to have it turned and chamfered, but is it really all that necessary??

Thanx

It all depends on how the crank looks. If it has no wear, no scores in it. if the bearings that came off the crank look good I would not touch the crank.

I never had any of the cranks I used turned. The 2.3L & 2.5L motors seem to hold up pretty well in the bottom end.

Unless you are racing or staying in the upper rpm band,chamfering is not nessasary.If you do it, you may have oil pressure problems at low rpm.A higher pressure pump will help with the pressure problem.I did it on a 2.8 because it was recommended.Then I took it to someone and they told me the bearings were bad.I told them the crank was turned,chamfered,and new bearings installed.They sold me a melling high pressure pump cured it instantly.I believe you can get a few hundred thousand miles out of a well maintained crankshaft.
