Hi folks im doing a 3.2 Omega engine conversion on my Vectra at the moment. I bought a GM timing belt kit for it and took on the challenge of doing it myself.
Anyway heres my problem, in the picture
Roller guide G1 that i removed from the engine had an eccentric hole which could be adjusted for tensioning purposes.
The new roller that was supplied in the kit has a central hole so there can be no adjustment made on it.
Has there been changes to the timing belt setup from vauxhall or have i the wrong part?
Also my instructions for fitting the kit relate to the adjustment of this rolller so if vxl have changed things has anyone got the updated fitting guide for this..
Also my belt doesnt have timing marks on it for initial setup either which i find strange.
thanks in advance

Oh dear. Seems a lot of the vauxhall belts have no markings. I have just done my 2.5 and the kit cam with the eccentric hole for adjustment.
I know from watching the DVD that there are 2 different types of kit.
Are you using a v6 locking kit?
I am sure someone with more knowledge will help shortly.
-
yeah im using the sykes pickavant v6 locking kit.
Seems like vxl are cutting corners, u dont wanna be doing that on such a critical part of the engine.
-
A little while ago someone on here had the same problem - not sure what the outcome was.
;)

See here :- http://www.omegaowners.com/forum/YaBB.pl?num=1186345510/6#6I also had a potential issue but fortunately my 2.6 was the earlier version which has the adjustable idler. They changed over at about engine number 8570000 or somewhere very close to the non adjustable one. Did you get your kit from VX or a factors - cause you'll get the non marked belt also. See Nickbats post - is very good reading and very educational - especially Kevin Woods input

yeah cheers for that folks, find it strange how the new kit from vxl doesnt have the adjustable g1 pulley with it because thats whats on the car at the moment.
How can i retard it 10 degrees from TDC, when the crankshaft locking tool is in place as well as the cam locking tools. Im not really wanting to remove all that while there is no belt etc in place. You be as well throwing the locking kit in the bucket than attempting VXL's cowboy idea of a belt change.
Maybe im being silly, i dunno....lol
Is it really that bad a job to do now!!!!, is there any document that i could print off so i have it beside me when attempting this suicide mission...lol
cheers for the comments
-
what dvd is there?? also whats your thoughts on my above post..
cheers
-
There is a DVD available showing the Omega cam belt change for £3.00
It show some of the experianced member doing the change.
Look for member Robin Hood.
Dont expect it has the new belt.
While its a stripped down worth considering changing the water pump as TC only £30.00ish
If that goes it will need to be stripped down again?
-
yeah i have the water pump, just need proper fitting guide. Im looking up vxl headoffice so i can have a moan at them over it....lol
-
You have a 3.2
The roller G1 is NON ADJUSTABLE on this model, which means that someone has fitted the wrong one in the past! (Probably VX main agent)
This is the most annoying one to change of all, so sit back and get ready to curse and swear a lot!!!
10 degrees is when the crank locking tool left hand edge is vertical.
-
Ronald cheers for the pm's,
Ok then
TIS2000, Autodata 2005 pc version and the Autodata manual and the sealey engine timing locking kit instructions show the 3.2 omega (y32se) engine to have an Eccentric Tensioner on pulley G1 and the fitting guide relates to this as part of the installation.
But the Vectra C 3.2 (z32se) shows a normal non adjustable pulley and relate to turning back the crankshaft 10 degrees etc etc for the setting up procedure.
I have the Y32se engine and my engine code matches the timing belt kit part number 93172354<<<<<< This is the same part number for the Vectra C 3.2v6 engine. ( the one without the eccentric tensioner)
So am i right in saying i should follow the fitting guide for the Vectra instead??
-
any feedback on the above post folks, im at a standstill until i get the correct info.
thanks
-
Sorry, well outside my experience range...... Hopefully someone will advise soon. ;)
-
Job done!! ;D
Anyway i followed the fitting instructions for doing a Vectra C 3.2 v6 as it was the same kit part number for that as it was for the Y32se.
Everything lined up perfect first time considering there was no marks on the belt, had a little adjustment on the tensioner after a good few turns so im pretty pleased considering ive never seen inside a timing belt case before....lol
-
Well done. I think you're ahead of the crowd doing a 3.2 cambelt - most people on here have 2.0/2.5/3.0's.
-
Great -- Any pics - What about a HOW 2 - :y :y :y :y
-
Sincere congrats on a good job, well done..... :y Plus, you have the added advantage of knowing that the timing is spot on and the job done to your personal satisfaction.
Small thing though.... When you find 5 minutes, could you possibly fill in the details of your car and location in the personal profile so that it shows with each post you make? No probs with wanting to stay as Mr Annon E. Mouse from wherever, it justs is seen to make this place more of the community that it already is.
Don't be shy to boast of how you managed to achieve your success either. If you fancy doing so, how about a howtoo? Have a look at some of the ones here already and have a bash at composing one for your particular 3.2 seeing as it has problems of its own that you overcome. Could be a point of reference for others to come. ;)
-
Well done, that man! :y :y
As you know, I had huge problems getting my 2.6 belt done during the summer. I think that, oddly, you're relative inexperience was an advantage. By that, I mean that, having done a 2.5 in the past, I was trying to adapt the old method to the new setup and that was one of the reasons I had so many problems. Incidentally, how did you get the non-adjustable roller on? Did you put it on last and did you use the 10 degree BTDC to get the tension on the right-hand bank?

once the belt was round all the pulleys the G1 roller should just slip into place..ie there should be no tension on it at all until you start tensioning up. I printed off the instructions but ill post up here with the pics but it wont be for a while as im back offshore tomorrow morning. Oh and yeah i did have to retard 10degrees btdc.
