Title: Timing chain
Post by: MP on June 04, 2019, 10:18:32

Can someone tell me what I do with the timing chain prior to taking off the head so that I don't affect the timing when replacing the head.

Thanks
Maurice

Set the engine a TDC "0" with the distributor rotor pointing to #1 spark plug wire. Do not rotate engine until head is in place and chain correctly installed again.

Thanks for that but what I need to know is what I do if anything with the chain before I take the head off

I taped it or tied it together with sprocket with the tritit bands (do not know the proper English word). But that was for camshaft removal, not sure if it works with head removal.

You do not even need to break the chain. Remove the tensioner, unbolt the camshaft front sprocket and slide the sprocket off with the chain. Remove the sprocket. (note that the sprocket has a front side and rear side because the off-set is different) The unbroken chain can now be attached to a wire and lowered into the gallery so the head can be removed.

Thank you both for the information.

Maurice,
The sprocket is kept in position on the cam shaft by a woodruff key (a small halfmoon key that slides in the slot) Cover the engine cavity with a cloth or towel to ensure the key does not fall into the chain gallery abyss. Also take note of how the key is inserted into the cam, because there is a slight possibility that it might be an offset woodruff key. If you intend marking the position of the chain on the sprocket, a white Typex pen works just great.
Regards
Chris
