Title: V6 Cambelt advice needed ....
Post by: I_want_an_Omega on 13 May 2010, 08:36:51
Hi,

I need some advice re V6 cambelt change as am stuck ......

I've got it all stripped down and am having problems at the stage before getting the old belt off.

I've got the crank locking tool on ok and am able to slip the red 1/2 lock in place with no problem at all as the alignment gauge fitted perfectly onto 1/2.

The problem I have is with 3/4. I can't get the alignment gauge to fit so have tried fiddling with the adjusters to no avail. I haven't touched the tensioner at all. I've been fiddling with the adjusters with 1/2 unlocked and can adjust 1/2 happily - but it seems to have little impact on 3/4.

I've been looking at the DVD - but this shows adjustment of 1/2 as 3/4 was ok - which is the opposite situation to what I have.

Thanks ........... Rob

Tried both the adjusters, but haven't touched the tensioner at all.

Might pop down the garage @ lunchtime for a fresh look/start.

Have been mulling it over and if can't get a "lightbulb" revelation from on here will try and adjust the old belt up in-situ as if it had just been fitted - if you can see my logic. ...........

Oh er ....

This is where you need to have done a few when you come across little problems like this.
Give me a ring  :y

Thanks to Daz for his excellent advice and morale support  - belt is now off and activity paused for a while now. Luckily I can just walk away from this and come back to it when I have another hour or so to play with.

An interesting note is that the garage who fitted the kit last time only decided to use 2 of the 3 backplate bolts :'(

So far I've chalked up a dead water pump, an aux belt and its  tensioner that was well past it and a missing bolt - I'm sure there is more to come with this little project ...........

No problem Rob speak to you when you next have tools in your hand ;D

You would be suprised to see some of the messes that some "Mechanics" leave these Omegas in >:(
More white pen marks over everything is a favourite :-? I was so confused the other week myself there was that many :D ;D

I took a weekend to change mine 4 yrs ago, I just couldn't summonse the enthusiasm  ::)
I cleared out my breathers last week when I did my cam belt, but removing the belt cover just highlighted to me that my cam covers were leaking more than I thought  :'( So cam covers is next ...... soon.

Sorry to get in on the act here, BUT - I am in the process of repairing my 2.5V6 (slipped belt) and tried a belt in the first instance seemed to get it fitted ok using the timing marks around the casings as I dont have the fitting kit yet.  I have read threads about the use of the eccentrics to get the belt exactly right, obviously there was no compression so new heads job!  I am about to put it all together this weekend as all the bits have arrived.  I intend to time it all up using the timing marks again - do you have any tips for me?

Yep, the timing marks on the back cover are just a very rough guide. Use a proper timing kit ;)
