Hi all,
I have just changed the cambelt, tensioner on my Puma, This is the 2nd Puma I have done in past 6 months using the guide on here and the gates bulletin 036 for setting the tensioner. I have access to a workshop with powered lift which makes the job a lot easier.
The first Puma that was done went fine, in particular after setting up the camshaft timing using the setting tool, and rotating the engine 2 revolutions, everything stayed in line (i.e. setting bar went back in).
However, with this car, after the engine is rotated the input camshaft is always lagging considerably as per photos - about 10 Deg out. The belt and tensioner are definitely correctly fitted and have followed the guide to the letter. After setting the cams with the setting bar and tightening to torque, when the engine is rotated by hand the exhaust cam rotates correctly but the input cam does not initially turn. It is something to do with the VCT unit. With everything torqued up and using a spanner on the camshaft I can move the cam about 20 degrees which I assume is the range of the VCT adjustment. I have tried taking out the 'play' before setting the cam but it always ends up out of position by roughly the same amount.
Interestingly, I checked the cam timing before starting and the input shaft was lagging then, although I would say by about 5 degrees rather than the 10 I have now.
Any ideas?
