Help advice needed for fitting timing belt kit

hi firstly i just want to say what a great site this is and its comforting to have such expert advice close at hand as everything for my lovely 156 seems to cost a fortune, i have decided to fit my own belt kit and have just purchased cam locking blocks , but that is all i have , is there a particular kit i need as i dont want to leave anything out while im at it , also what special tools will i need besides the blocks and where do you get these tools? , has anybody got a step by step guide?? , that would be a lifesaver , any help very much appreciated

Re: advice needed for fitting timing belt kit

1st question, not a patronising one, have you done a belt before on any other car???

Re: advice needed for fitting timing belt kit

you need something to lock the crank, a screwdriver on the flywheel teeth does that job nicely. cowboys will say stick it in 5th to lock the crank, but that leaves more than enough movement to cause serious problems so dont be tempted.

you will also need something to determine the position of the piston in cylinder1, a long screwdriver inserted in the plug hole can do that, howver if you lock the crank and both cams before you touch the belt then you wont need to do this unless you want to inspect and correct the timing, but if it aint broke dont fix it.

you also need tensioner adjusters for both the cam and balance belts (balance belt only on 2.0, you dont say which you have). you can easily make your own tools for this (see the haynes for fiat bravo, the 1.8 section) or just use common sense when tensioning. the correct tension is critical but getting it right really is common sense.

Re: advice needed for fitting timing belt kit

???
I haven't had the 'joy' of replacing the belt on mine (yet), but there should surely be timing marks on the different pulleys to mark the correct position.

Also, are there not auto tensioners on an idler on the belt?

I don't have access to my manual at the moment, but that would have been my past experience.

Re: advice needed for fitting timing belt kit

There are no timing marks on the TS engines hence the need for cam locking blocks.

Re: advice needed for fitting timing belt kit

The greatest challenge is removing the flywheel pulley. These are very tight and a standard impact gun will not shift it. I did a belt and water pump change on a v6 last year, with engine in car. It's a big job especially without camlock tools. Improvisation, as JUG says, is a perfectly good alternative provided you are not in a rush.

Jamie's brilliant coverage on the Alfaworkshop site is the correct route map to follow, guess that's the link referred to?:

The TS is easier though, as the pulley held on by 4 ribe bolts. Torx T40 will do just nicely though.

Re: advice needed for fitting timing belt kit

The Thema turbo was straight forward enough. In fact it was an enjoyable exercise, just needed to lock the flywheel, to undo the left handed crankshaft pulley bolt, at about 130 foot lbs? The rest was pretty uncomplicated:

Re: advice needed for fitting timing belt kit

I haven't locked the flywheel when changing the belts on TS cars, I usually lock the cams, undo the pulleys so they are loose, put the belt over, turn the engine slightly until piston 1 is at TDC then tighten the pulleys. After that set the tensioner tension This I believe is correct, it has worked for me 3 times now.

If the belt is a tooth out you won't be able to get everything to line up, and its important not to let the engine turn backwards whilst doing this.

Re: advice needed for fitting timing belt kit

I really think that Thema 16V was a much better dohc set up than that deployed on the Alfas? Ok, it was also a far more expensive unit to manufacture, but I loved it.:
