Do you have to be at top dead center to remove the cam chain tensioner ?

My clymers doesn't mention it, but I read on here- and I assumed you needed it to be - so that there's no valve pressure on the chain.

Can anyone clarify?

I've got a leaky rear CTT gasket on the rear cylnider & was hoping to just unbolt it and slap a new one on...??

I don't think so. As long as the cams are still bolted in the only pressure the chain's under is from the tensioner itself. I believe TDC only matters when you're checking valve clearance and changing shims.
Not true. If the cams are not exactly centered on the followers and you undo the tensioner the spring pressure will move the cams. The cams are on different centers so it is nearly impossible the get no pressure on the cams without rotating to tdc. It is soooo easy to get tdc why take a chance by not doing it?

Hey, thanks guys. I find it strange that the clymers doesn't mention it...but I'll stick it at TDC.

update: the clymers does explain to put it at TDC, but it is a few pages earlier. I had to remove the valve cover to verify the compression stroke & that the valves were not under pressure.
