The importance of measuring bell housing runout.

Nice post from Dan
Its made me think about it a lot more

so that motor where you had to get a shorter timing chain
the one where the rear main seal always leaks, where you had to go back to rope and it didn't quite work out

bet that's also the motor that cracks flex plates or is hard to shift

if its been line bored to any great extent aftermarket main caps or any reason the crank is potentially a few thou closer to the head than it was and that'll mess totally with the alignement of the bellhousing register in relation to the crank

this shouldn't be a revelation to me, its bloody obvious But you know what..... i'm a bit slow....

it also means aftermarket block where the hell is that centred......
i'm sure they all align with each other and that crank will turn like its in butter but.....

if you only do a limited run of 100 or 1000 you are gonna make damn sure they all go out the door for retail sale regardless

Couple that with aftermarket housing well could be half a mile out....

broken starter anyone....

i'm on a roill ... probably time to stop :) 17:30 friday afternoon is time for beer
