96 Geo Tracker Timing Belt Slipping

Cody.Hartman · Jul 29, 2011

Recently the timing belt has broken off, after replacing the timing belt the mechanic who was working on it torqued the bolt that belongs to the pulley on the water pump to much causing the threads to strip, after replacing the water pump and putting on the new timing belt (and it it timed correctly) when started the belt will begin to move forward and eventually fall off, any ideas and advice on how to fix this?
Thanks

Any possibility the old waterpump/pulley had a flange at the side of the pulley to limit the belt's movement, or a tightener did and something is now different in those areas?

Another cause could be there's something wrong with the waterpump and it's shaft isn't EXACTLY perpendicular to the mounting face or the edge of the pulley isn't exactly the same distance from the pump's mounting face. If the tightener was replaced, could it possibly not be "true" walking the belt to the side? Do you the old parts to compare/measure?

It's even POSSIBLE the new belt is defective/has broken cords/was damaged being pried into place, making it "walk" to the edge of the pulley rather than run "true" and stay in place.

do you have the instructions that came with the cam belt component kit...

last one i did had a flange on the cam shaft so it could not move forward

Take it off & turn it around & put it back on. If it still walks off the front, you have other problems. Not the belt.

Go to www.kick-fix.com (created by a retired Suzuki mechanic) and click on topics until you find "crankshaft damage". Suzuki (Geo Tracker) 4 cylinders with belted cam
drive are susceptible to crankshaft damage if the
crank bolt is torqued to less than 50#. Never reuse
a crank bolt. They should be torqued to 94#. They are $9 from Suzuki. The crankshaft timing sprocket or pulley has a keyway
to index it on the crankshaft, but the only thing
holding it from moving on the crank is the crush
between the crank sprocket bolt and the shoulder on the crankshaft. The website above shows many pictures and different repairs of damage as an alternative to replacing a crankshaft.

This key way/ key wobbled out on mine...I figured the crank was a goner anyway and shot a tack weld on the nose of the key. Been running it around for several years now.
