timing belt issue

[speedyfreak86]

i Have a 92 cb7 that i recently bought and i had to replace the timing belt. no issue there but i was driving today and i think the timing belt went. the car died and wont kick over it cranks but wont start. I dont know if this is just a belt issue or if its being caused elsewhere. if anyone has had a similar issue or know what may be the cause id appreciate the input, Thanx

when the car cranks over does it sound like normal cranking? or does it sound like a cordless drill or maybe a blender? scary fast cranking = broken timing belt

could be the main relay. do you hear a fuel pump priming when the key is turned to the ACC position?

remove distributor, have someone crank engine...if you don't see the cam spin...broke belt...fucked engine.

or you could just pop the valve cover off and look for a busted belt.

or try to take just the belt covers off and see hard to do

the belt is still in one piece basically. it shredded down to about a 1/4 in thickness and was able to slide off the sprocket, what could cause this?

Pull the side covers off and see if you have a clearance issue.

If the pistons were moving, and the valves were not... your motor could be toast. That's what happens when the timing belt breaks or falls off.

If the belt shredded and came off, I would question the installation of it. It shouldn't do that, unless something is done wrong.

[lost_accord]

either installation or existing problem. The OP says that the car is a recent purchase & got the new timing belt then. So something keeps destroying them or no one can put one on the car correctly.

It almost doesn't matter at this point, what caused the failure. The first order of business is to determine if the valves are screwed up.

Are the teeth ground down or is the belt width reduced? Also, when you replaced the timing belt, I am wondering whether you replaced the tensioner pulleys and springs?

Sorry about your car, I have a 92 too.

i didnt replace the tensioner pulley or the spring, and basiccally it looks as if it was worn down and now has a smaller width, enough for it to slide off the with the cover installed.

as stated before...something went wrong during installation.

Demand your money back. If the shop manager gives you shit, threaten to sue because they are supposed to do things properly, no matter what their written policy is. Don't turn the engine until it's been fixed at a different shop. You sound like you have a clue anyway .

why would you not replace the tensioner

It is best to replace them, but this is not always needed.

My tensioner, idler, water pump, crank and cam seals were not replaced at my first t-belt change (110,000)...only the water pump began seeping at the time of the second change (200,000)

still...usually IS a good idea
