Timing chain

Does anyone have a picture of how the tensioner on the chain fits, i meant the bar with the teeth in it. I presume it has to latch into the little bit on the sprocket end of the tensioner but i cannot make it do it. I just want to check if i'm doing it wrong or if its broken.

thanks

The tensioner is oil fed , and when the chain stretches thru wear , the oil pressure forces it out and then the ratchet teeth hold it at that extension untill sufficient wear allows the oil pressure to force it along to next serration . Have you got correct chain as it should be held by ratchet mechanism to start . HTSH

i think there was a mod to slipper type that used a shorter chain

It should be the right chain, i took it off the landy a couple of days ago!

you just hold it whilst compressed ,have you timed cam properly unless its exat its pointless rebuilding

Followed workshop manual guide and set the timing, took me a few goes to do it though!

Do you mean hold the ratchet bit on while compressed? Because i've got it all fitted back on, its just the ratchet does not seem to bite onto the bit so it wouldnt ratchet if it needed to.

rachet stops it compressing just hold it out of mesh whilst fitting

I see what you are saying james but i have a query.

I've got it fitted like that, but if you push the end of mechanism with the sprocket on, then then it compresses and the ratchet does not stop it. From what everyone has said its meant to stop it compressing, or am i just reading it wrong?

has it got its spring fitted correctly or are teeth worn

The spring goes on its bolt and the on top of the ratchet and on top of the housing for it on the right ( if that makes sense ).

Basically its the same as when i took it off. Teeth look nice and big and sharp

does idler sprocket move along its slide ok ,is it just stuk between teeth

Yeah it moves along fine.

I think it might be stuck between teeth, i've tried pushing the chain tighter to let it bite in but it wont go. Should i just leave it like that?

yes if pawl is sprung down onto tooth and everything moves ok

No piccies, but there's a good exploded diagram in the parts catalogue that shows where all the springs and bits go.

Don't shove it in to engage it - friend of mine did that on a IIA and the thing whirred like a fiend (too tight) when reassembled. If it is floating between teetha that is fine - the oil pressure will take it up to the proper tension when the engine fires up.

Working on it again tonight. Got it all fitted and was turning the engine over using crank and i noticed that the timing chain was slipping and missing a tooth or two causing the timing to go up crapper.

Any ideas why it'd do this? Everything is fitted as it was.

which way were you turning it clockwise or anti as looking at the front

clockwise

something out of line ,tensioner in slot fully,pics ?

Tensioner is fully in the slot.

looks allright crank pulley right way round ?
