? about timing belt install.

[danyz250f]

My motor is in my basement now, and I am putting my timing belt on. I dont have the special mitsu tool so I just wedged a wrench in between the pulley and the tensioner arm. I can get the belt really tight but when I turn over the motor it will start to bike chain off the tensioner pulley and off the crank pulley. Not all the way off but like a quater of an inch.

Is there a washer or spacer that goes behind the pulley tensioner bracket or do I just have the belt to tight.

You don't want the belt really tight. Too tight is just as bad as too loose. There is service specs of what the belt tenion and specs are in the book.

looks like I get to buy the belt tensioner tool.

No its not needed. When I tention the belt with the blue tensioner pulley, I lock a allen wrench in a pair of locking pliers and tension the belt that way. Its a bit harder but it works. I then turn the engine over by hand for 6 revolutions, re check timing and check its tension, then let it sit for 20 mins and check again. If all is good I finish it up.

How do you lock an allen wrench in the pully with plyers, and how do you know when you have enough tension. Do you put it in one of the two holes in the pully some how?

Also is the problem with the belt turning off the pulleys caused by being to tight?
