What to do when I do the belts 156
« on: March 29, 2018, 07:30:05 AM »
Hi I have the daughters 156 jts 2.0 that needs a Cam and balance shaft belt. I was going to do the water pump at the same time but what else should I do?

Can I just put the spring kit in the Variator or should I replace it. And in doing the spring do I need to do the variator bearing as well?

Itís done 200,000 km

Happy for ideas.

Cheers Matt

Doing something with the variator is a good idea, the refurb kit is appreciably cheaper than a whole unit. A new seal is good practice.

Youíll still need the variator socket, the TDC tool set, all the usual kit plus I recommend a counterhold tool for the exhaust cam sprocket.

Out of four TS motors Iíve been intimate with, one had slight weeping from the balance shaft oil seals. All had weeping from the balance shaft end caps at the opposite side but only one is accessible with the gearbox still attached.

I have just finished a head gasket change on a JTS, water pumps are not expensive and simple to replace once the belts are removed so it might be a good time to replace it. As CB said TDC tool and cam locks are a good investment and with the belt tensioning tools it make the job a lot faster and easier to do. The spring and seal kit for the variator can be hit and miss depending on how much the variator is worn. Check the variator bearing when you remove the camshaft and decide then on replacing it or not the bearing in my car was in perfect condition but the variator was knackered, use red thread lock on the variator to camshaft threads

ALWAYS replace the Water Pump when doing belt change, 1/2 of belt failures is due to water pump bearing failure. You must remember the water pump is also a pulley.

This shows why very clearly -

What is the deal with the TDC tool why canít Alfa just put in timings marks like every other car?

Itís far more accurate.

There are some indexing marks but theyíre not to be considered reliable.

With any older Euro car, purchase price is just the entry ticket.

A new variator kit is not always successful maybe it's because the ring no longer seals in the bore. it might be worth having a look at the condition of the bore, Then order what you think you might need either a rebuild kit if the bore looks good or a new variator if the bore is buggered. I have not seen a rebuild kit with a ring included

May I suggest just buying a new Variator, the last thing you want is to find out that a rebuild didn't work and having to the whole lot over again.

Good point, best bit is the entry was only $500
