    06D REMAN

    Just wanted to post about this service call I went on for a new account and the carnage I found. Oil was all over the roof. This job was repaired and completed last July 2010. GWS bearing head assembly.

    It was my first time ever seeing one do that also. When I say repaired, another 06D was installed after a new bearing head assembly was tried. Immediately upon start up the 06D pulled LRA. I recommended replacing the 06D instead of messing with the bearing head but that didn't happen. As my mentor used to say, "Some people pinch pennies, while the dollar walks right out the door."

    I`ve seen that happen on a 06E one time.

    It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.

    I think I know. Well, Not exactly why without inspecting the compressor but in general...

    It's pretty obvious by looking at the bearing head that it failed due to excessive axial loading. The only way that was possible is for it to "bottom" out against the crankshaft before it seated against the case during assembly. As the bolts around the bearing head were tightened they attempted to bend the outer ring of the bearing head to meet the compressor case. Cast iron doesn't bend very well so this is the result.

    As for why that happened, incorrect thrust washer or improperly machined crankshaft would be my guesses.

    I was thinking along the same lines.
