Technical Timing Belt help

[ycming]

oko, in thge middle of fitting the timing belt.

I have made marking on both top pulley and bottom pulley before i took it off

Now i have got the new belt on, but everytime i try to put tension on the belt, the bottom pulley moves as well ...

Is there some sort of trick to keep the bottom pulley steady ??

Thanks

If when you tighten the cam guide bearing the marks are off, move the crank pulley to the next tooth and then see. I just pull down on the font of the belt and line it up to the crank one.

oko ... now i struggle on putting the belt on .. really tight !!!

Any tips !!??

Breath in???
Remove crank pully (3 bolts), slacken guide bearing or remove, Belt should now slide on. Check teeth are engaged in water pump drive.

Hmm

the crack pulley is off.

Guide bearing = tensioners?

If i take that off, slide the belt on , and now trying to the guide bearing on, is really tough !!

I'll just keep trying !!

Pull down on the belt under the waterpump, get a spanner on the crank bolt, turn the thing anti clockwise a little to locate belt tooth in it and then rotate clockwise to tension belt. Tensioner should go on. Aply some tension to tensioner and tighten up and check timing. If out then repeat earlier procedure by first setting cam then use crank to take up slack. You have to estimate where the crank mark will end up after you move it to tension the belt. I use a camshaft locking tool to take up the slack.

The alternative is to lock the flywheel. It's in the Haynes. You not got one?

 

[ycming]

I'll got 2 ... i go out and try again !

Will update shortly

Just a thought???
Is it the right pitch belt that's been supplied? That might be the reason for tightness..?

 

[fingers99]

Could be. That one came up on the other place!

 

[ycming]

anopther silly question and easy question.

Should the arrow of the belt points towards the exhaust or inlet manifold ??

This is the first time i am doing things to the fire engine

Thanks

i got it from fluffy .. and not really sure how to tell if it is the correct pitch one.

Ming

 

[ycming]

comparing to the old one, it seems the groove (or indent) is wider than the original one that came out.

around 50% bigger.

It's unlikely that Fluffy will have made a mistake (but possible): but he can only go on what you tell him.

To check, you hold it against the pulley of your choice and see if it fits properly. The grooves on the belt must engage with the grooves on the pulley, the belt must lie flat on the pulley, etc.

Surely the arrow is direction of engine rotation: in that case, the engine turns clockwise as seen from the timing side.

Here is a picture comparing the 2 belts, then i go lay the belt against the pully and let you see




Even the goove on the new water pump and old water pump is different ???

IT seems, the pitch on the new belt fits the new water pump, but it does not fit the top and bottom pulley.

I'll go get a picture now!

Totally different!

 

[ycming]

What about the new water pump i got ? the new belt seems to fit that fine ???


I am soso confused!!!

Ming

 

[fingers99]

Yes. You need a new belt and waterpump (unless you can swap the pulleys over for those on a 1108 that match the belt).

 

[ycming]

Here is picture of the new and old pump (new one has been fitted to the car)

old and new belts again the pulley.

 

[ycming]

I have came to the conclusion that wrong belt and wrong pump ..

anyone agree and disagree ?
