Hi all, rarely post but read here often.
So, I just side stepped turning my 1Z engine into scrap yesterday: after replacing the serp belt tensioner (bush had gone) I noticed there was a lot of pulley wobble (harmonic balancer) at the crank. Also recently starting has been difficult, and after reading about crank nose issues I found a post about the lower gear slipping, causing timing to shift and a light bulb appeared above my head. Id thought the hard starting was air in fuel or similar.
Anyway, I got the pulley off and it was the gear running out, the crank bolt came off with no effort at all, and the D shape inside the timing gear was no longer D shaped : (
The crank nose seems to be fine tho, just the timing gear appears chewed. so I plan on fitting the timing gear and harmonic balancer/pulley from an AHU I have spare. I understand as long as they fit properly (crank nose not chewed) and I properly torque the NEW bolt up, all should be well.
1st question, is there an issue with that? I assume theyre compatible (AHU bits > 1Z crank)
2nd question, somebody I know suggested using a crank bolt for a 2.5tdi, and also using a diamond washer. Anybody here ever done this? How would the washer affect the torque procedure? I like the idea of the kick ass washer, but also like the concept that standard is good enough, especially if it could mean I unwittingly over torque or under torque the new crank bolt due to the extra friction...
Cheers all, monkey
