timing chain tensioner z24 - Pirate4x4.Com : 4x4 and Off-Road Forum

newgene · 10-23-2004, 07:12 PM

Am in the process of changing out heads on a '86 Nissan 4x2 (z24 engine). I cannot seem to get enough slack in the chain now to reinstall the cam sprocket and chain. I did use the block of wood to keep tension on the chain, however it seems that nothing will give. I found some older articles about the tensioner coming out of it bore, but was wanting to talk to someone before I pulled the front cover to see exactly what the problem is or might be. Thanks for any help.

Did you get this figured out? I've run into the same issue. Anyone have a suggestion?

The tensioner on the z-series motor is held in by a spring...

as soon as the chain has tension taken off when the gear is removed, the spring pops the tensioner out of it's bore. Gotta pull the timing cover off and reset the chain in the guides and the tensioner into the bore. Pretty easy.
