Re: Have I got the right cam locks?
Just to update you on my progress so far. I ran out of time yesterday, so I didn’t manage to get it all back together, but I did manage to get the belts sorted.
I discovered that the problem with the cam locks was that the bolt holes were offset the wrong way. The bolt holes in the head are offset, so that the caps cannot be replaced the wrong way around. I elongated the bolt holes in the cam locks to negate the offset and was able to bolt them on and lock up the cams.
I have to say that I agree that it would be very difficult indeed to do this job without cam locks. The new belt had very little play in it and I would not have been able to get it on without loosening the vernier bolts on the inlet pulley. Without the cam lock I would have lost the timing.
Overall, this is not a particularly difficult cam belt to replace. There is a lot more room than on some cars I have done in the past. However on a couple of occasions I wondered if I was out of my depth and the main reason for this was the lack of a decent Haynes type workshop manual. That workshop CD is worse than useless. l had printed out the guides on this forum and I think without them and you guys, well.. who knows.
One thing I did discover, although when I opened it up, there were no horrors to report, the old cam belt was clearly stretched and therefore the tensioner was ‘unloaded’, so to speak.
I wonder if the reason these belts and tensioners are failing is more because the belts become loose and suffer backlash!?.
