My 6.1 retrofit thread
One small frustration was finding something suitable to press the balancer back on with -
Even if I wanted to, I couldn't use the crank bolt to press the balancer on because the interference fit was too snug to engage the bolt.
The other hassle was that the crank bolt is M14 - 1.5 Fine pitch thread...so getting a long full thread bolt from the hardware wasn't an option.
Eventually I settled on some M14 threaded rod, two washers, a gudgeon pin as a spacer and a hardened steel plate.
It worked a treat!
Finally finished re-assembling the engine today - all set for a trial install tomorrow - this will be when I find out how the TTI adapter mounts will set the motor up, and if I need to clearance the inner guard for the alternator.
