1" cambelt kit.

[Steve Webb]

I seem to remember reading about this 1" wide cambelt conversion a while ago. Just wondering if anyone has it fitted?

[Juan AR155Q4]

It was a conversion using parts from a Fiat Ducato I think. I remember that countershaft belt should be removed.

I bought one, the offset on the crank pulley is wrong which means the belt overhangs the camshaft pulleys, this means that whilst you have traded up to a bigger belt it's not much use if some of the extra width isn't being used and hanging over the edge.....

I had to re-engineer it all to make it work. If you are running standard or only mildly uprated cams then stick with OE, if you are running some wild profile cams on a serious engine then then the re-engineered kit is worth the money IMO.

I have one set on my car.

Pictures:











The belt goes out about 1-2 mm. I don`t do anything about that. Engine is still in working condition.
Engine support has some mild modification, otherwice your belt will hit on that support.

This is what it looked like when I did a dry build:



I turned the engine over a fair few times till it settled in, then I compared the new btm pulley with the old one and noted a 3mm difference which explained why it was doing this.

Does the original cambelt cover still fit over the pulleys?

[T M Oren]

Did you remove the belt for the counterchafts?

[Evodelta]

Did you remove the belt for the counterchafts?

Yes you have to, it won't fit with them.


As to whether the belt cover fits on a Q4 or not I don't know, you would hope so because without it you are skating on thin ice....

[155-tbo]

Belt cover will fit. No problem.

Evodelta: I have the same problem with that belt line. It goes out about 1-2 mm. But it`s still better than old thin belt.
What was the difference between new and old btm pulley? 3mm, but where? has the new one 3 mm extra wide or what? How you re-engineer that parts? Do you have pictures after they were re-engineered?
