Question Crankshaft Timing Gear

Im trying to pull the timing chain gear off the crank,its a complete short block assembeled . After finding a puller small enough to fit , it broke on of the bolts on the puller , probably just cheap bolts. Is there something Im missing here, or what??

I probaly have 3 pullers that will work, the 4th is a chisel, and a wooden handel furd
torque wrench. Place chisel above keyway. Smack with furd tool it will split gear, check
sprocket carefully toss in trash.

I'd replace the bolts with Grade 8, if a jaw puller, and install the puller again and apply a good pull to it, then heat the sprocket - it may just 'pop' right off or move some, repeat.

Oxy/acetelyene torch works good for applying fast heat, MAPP gas next, and finally propane gas.

Re: Crankshaft Timing Gear

I have always used my OTC 10" 2 jaw puller to pull these always making sure I have some type of bearing as a pilot in the crank bolt hole. Seems the longer jaw puller pull straighter where the smaller ones will slip if you don't have means of clamping the jaws.

Might try loading your pull and tapping the turn bolt with a hammer, to jar the sprocket. Go back with some anti-sieze.

If I'm not mistaken, me thinks I used a 6" gear puller to remove zee cranker sprocket!
