:rocker :die I have done a number of these but is there an easy way to stretch the timing belt on? The idler pulley alwaysseems to be too tight if it is in the slot and even if it is loose. :smackface Thanks!

I take the long stud bolt off so the thin adjuster guide so it can be pulled farther back than the adjustment off the slot. I also pushed the adjuster past the water pump casting line it hits bending it out slightly.
Even then its still been real tight to get on new belts. The tightest I belive I walked on the cam gear from the adjuster side and turning the gear clockwise while pushing the belt on.

One of the tricks in forcing the belt on sprockets is to keep as small edge as possible on both sprockets until all contacting upper teeth of cam sprocket are engaged progressively from right to left. Only after complete engagement the belt is pushed onto the sprockets little by little at different sprocket points.

This calls for some special engineering. Maybe re-engineer the cam lever? I just got done making an engine roll around stand and a brace for my engine stand. After all I have two more of these to do! Thanks all. I think I used the "get the wife for a third hand" and had her turn the engine while I rolled it on. I think I tapped it gently with a rubber hammer.

I don't know...I have done several timing belts on the 1.0s, I just loosen the tensioner pulley, maybe even took the tensioning spring off, then I line my marks and then with the belt fully on the crank pulley I just slip an edge of the belt over just the edge of the cam pulley then just kind of work it on with a little pressure.

I did one on the side of the road one time, easy peaze nice and easy.

If it's that tight it's going to wear out the #1 cam bearing.

Just my .02¢... :type
Remove the Tensioner pulley, but leave the lever attached with the sliding 10mm head bolt/stud (snug the bolt, do not tighten it)...
line up the timing marks...
install the belt keeping the tension of the belt towards the exhaust side of the engine...
Then mount the tensioner making sure the levers notch lines up with the hole into the back of tensioner...
loosen lever, let the spring do it's job and tighten everything down...

I have come across a few belts that are too small to work, and they are too tight in the loosest position. Indeed, these will do damage if used.

+1. I always push the tensioner to the loosest position, and then hand tighten the long bolt like you have described to hold the tensioner in the loosest position. It's a pain reassembling the tensioner against the belt if it has been removed.
