CAMSHAFT INSTALLATION

[CMF_GTRHOLIC]

hi all, i just bought some cams and was wondering if they were difficult to install. has anyone installed cams themselves? any advice? do i need anything special? any help would be appreciated.
thanks in advance

Yer iv done some my self. You have to get the new came to sit in the same place and angle as the old. I suggest you mark every thing you take off. So you can put it all back in the same place. I always do that. Hope that helps

hmm... what about oiling etc? can you give me more of a step by step?

Consulted your haynes chris?

Are the cams new? If they are they need to be run in. Jump onto the crow cams web site they have info on bedding in cams. Other than that use plenty of cam lube & make sure the timing is right.

micra valve clearances are set by shims which sit between the valves and the cams (on top of the cam buckets which sit on top of the valves). these clearances must be correct for the engine to operate properly. the required shims should be available through nissan or a good head shop. it is a fairly time consuming and involved process that must be right. if this is not done right you could be up for very expensive repairs. if you are not confident to do this then leave it to a professional.

hmm.... do hydraulic lifters have to be shimmed too? aren't micra lifters hydraulic? shims are very expensive aren't they? what are they worth each?

 

[CMF_micrat]

micras don't have hydraulic lifters, they have solid (shimmed) lifters

out of curiousity which cams did you buy, what are their specs
