Title: timing a 2.5td
Post by: davidlandy on November 17, 2004, 21:05:17

A friend has a 2,5td which has thrown its cam belt.

who can advise on how to time it up again? (Guy?)

tried lining up the dots and arrows like the haynes lies book says but when you turn it over it locks up - feels like a piston hitting a valve. hmmm

help  - thanks

You need to make sure you start from TDC with everything.  Not difficult to get the camshaft in the wrong place (with the dots lined up)

Dave,

Was that why Jason was trying to ring me tonight? I had no luck with this and got the same thing. And that was after setting TDC. Gave up in the end and took it to garage. Never did get all the dots to line up :cry:  :cry: .

Yes Guy  it was  - the thinking being that you had been there so may know what to do! :oops:

Tim,

Getting the dots lined is a nightmare - would it being one notch out cause the whole thing to lock ?

also the cam pulley dot is lined up with the arrow on the casing but when we peer through at the valves on no1 they are open not both closed - is that right

 :?:  :?:  :?  :?

Being one notch out could well cause a valve and piston to meet, yes.

I can't remember the exact procedure, as it's been about 18 months since I did a TD, but you need to get the piston at TDC on (I think) the compression stroke, which would mean both valves closed.

I'll see if I can dig out the manual and confirm that.

Surely on a 4-cylinder it's the valves that decide whether TDC is compression or exhaust/inlet overlap.

I told him when it happened to check the push rods and rockers :roll:  :roll: .

I got mine from Craddocks. They were pretty cheap as I remember.
