I am working 0n a 1983 fleetwood with a ht4100 engine. I am now replacing the timing chain but can NOT get off the crankshaft flange for mounting the harmonic balancer. Is there a special puller needed. I try a pretty big 3 jaw puller but no luck. Ant help is greatly needed asap. Thank you in advance.
Be careful with a 3 jaw puller!!! It's not hard to damage those things; especially Buicks. I haven't messed with a Caddy 4.x balancer but I suspect there may be some holes or slots with holes inside to thread a puller to. Time to invest in a manual. Good luck.
ive got a 84 fleetwood brougham and i just replaced the timing chain on mine and if i remember correctly i did use a harmonic ballancer pulley puller that i rented from autozone and it came off with a little force just dont ruin the threads on the inside of the crank shaft you will need it to reinstall. i did have a hard time finding the right threads for the crank to reinstall though.
