(T) Fitting a Punto 75 camshaft in a 55

I've bought a 75 cam complete with followers and shims, just want to check a few things before fitting...

(1) I assume that the clearances need to be set as for a Punto 75, not a 55 - is this right?

(2) Are the followers off the 75 any different to the 55 ones, or can I just use the original 55 followers?

(3) To shim it, is there any better technique than trial-and-error? i.e. just putting random shims in when fitting the cam for the first time, measuring the clearances and changing as appropriate) And can you change the shims without actually removing the camshaft?

(4) When fitting the pulley, is it possible to fit it the wrong way (i.e. so that the timing is out even if the marks on the pulleys are properly aligned)?

Cheers

Use feeler guages then add the gap to the size of the existing shim and thats the new shim size you need.

Cheers matey! So just go with random shims at first then measure the gaps and change as appropriate

yep, also not all shims have size on so you use a micrometer to find some the right size,

Short but sweet!

Cheers fellas I'll let you know how it goes - if I ever get a rain free day to fit it!

Are the clearances for Punto 75:

0.25mm to 0.35mm for inlet valves?
0.35mm to 0.45mm for exhaust valves?

(if so, than they're the same as for the 55 model)

nonono, on the 55/60/cinq:
inlet 0.35-0.45mm
zorst 0.45-0.55mm

on the 75:
inlet 0.35-0.45mm
zorst 0.40-0.50
