cam chain tensioner

[nathan]

hi im just wondering should the tensioner have any play in i have it out at the mo and i can push it in about 4mm is this normal or is it nakerd

Isn't it spring loaded so that it puts tension on the chain (hence the name)? - Or have I misunderstood what you're asking?

i was once told that there hydrolic. not sure if thay are though.

im sure it is hydraulic so once the car is up and running should take up any play like a hydraulic tappet , you usually lose the oil out of them when you have to compress the piston back in to put on the little retaining clip, before fitting .

 

[vss irvine]

they are controlled by oil pressure, as the chain slackens over time, the tensioner gradually moves out to take up the slack.

as it does, it comes out on a ratchet system so that i stays out even when the engine is off.

Hiya,

Any pics of the tensioner in situ? Am I correct in thinking that the tensioner has to be fully removed before removing the cams or just loosened?

Thanks,

Lee
