I have been trying to complete the install of a new timing belt kit and waterpump. The problem i have is that the new belt appears to be too short to fit. I have measured the new belt and it is the same length as the old one and have checked the diameter of the new waterpumps sprocket and that is the same as the old one. The new tensioner is the same type as the old one as are the idler rollers. I eventually found a post on the waterpump position and have used that and compared it to the marks i made from the old pump and they all match. The new belt looks so far off fitting that i can't imagine being able to force it on. I have tried adjusting the pump position tonight but though the first adjustment seemed to improve things, when i moved it even further it seemed to get worse again. Is it just a case of being brutal with the belt and trying to force it on or is there something i am missing here? I have done a few cambelts before on MR2's and they were nothing like as tight as this one appears to be.

Does it look like this?

Hi hairy, thanks for replying. Yes it does look like that; that was the thread i used to find out about the water pump positioning. I also printed off the thread about fitting the VXt cambelt. The routing of the belt is correct but it just seems far too tight to position on the inlet cam sprocket. Should i be expecting to have to use a lot of brute force to get it on rather than it just being a bit awkward and fiddly? It still looks almost impossible to get on to me and i am loathe to try any harder until someone can confirm that it is normal for this job to be a complete pig. I have looked at various videos on Youtube of folk doing these engines and nobody seems to have had to fight with it excessively to get it on. My next step is going to be to put the old water pump, tensioner and cam belt back on to see if it is as difficult as the new one. If it goes on alright i will then try putting on the new belt with the old tensioner and pump in situ to try and eliminate the belt as the problem. If it does go on OK i will then introduce the new tensioner first and if that works add the new water pump to find out if either of those are different or faulty though i can't see anything obvious. As far as i can tell the tensioner is supplied in the full off position so there is no room to be gained from that though i am happy to be corrected if that is wrong. It might be that i am suffering from too much mechanical sympathy but i really want to be sure before proceeding.
