timing chain too slack or not

(1/2) > >>

disco-v8:
ok about 9 months ago i changed my cam on my rover V8 3.9 which also included changing the timing gears and timing chain....

ive just looked at it 2day and there is abit of slack in it already but dont no if its too much????

how much play should there be between the cranck and the cam (in degrees)?????

another words my cranck can move slightly without moving the cam, is this ok???

lurch_917:
?? when you changed the chain did you check the tensioner spring and slipper as i had this on a jap motor and had to change the tensioner slipper and spring

chris9119:
When you installed the new one, what procedure did you follow...... :?:  :?:

I would follow that one again and if its out of spec, adjust it...... :idea:

I didn't think the 3.9 had a tensioner? it looks like the chain is so short it wouldn't be needed, also there is no mention of it in the official LR v8 manual.

Guardian.:
to be honest i dont know, but, i would not have thought you should be able to move the crank and not the cam for any degrees, that sounds very slack to me.
plus if it doesnt have a tensioner, how do you tension the chain?
