berg Posted March 7, 2016 Share Posted March 7, 2016 (edited) After a bit of advice to remove the harmonic balancer pulley Bolt is off its just the pulley thats stuck Ive never had a problem with these before using the correct puller but this one wont budge Ive tried the proper puller using the 2 threaded holes but somehow it managed to pull one of the bolts out and half the thread came with it so that leaves me stuck The claw type pullers wont work either and only damage the metal on the edge of the pulley I have a new pulley so im not fussed what condition the current one ends up in, it just needs to come off Edited March 7, 2016 by berg (see edit history) Quote Link to comment Share on other sites More sharing options...
Scooter Posted March 7, 2016 Share Posted March 7, 2016 If you have a narrow (1" ish) plate of metal with two holes aligned with the threaded pulley holes you can put one bolt back in as normal and hopefully get a bolt through the damaged thread one and a nut on behind? If you pop the pulley bolt back in before fitting the plate and then slightly pack out with a couple of washers the front of the plate, then you should be able to get a 22mm spanner onto the bolt and unwind it against the plate?

Chris Wilson Posted March 7, 2016 Share Posted March 7, 2016 Drill and tap two new puller bolt holes? Helicoil the damaged one? Always ALWAYS run a tap down them, use cap heads, due to their strength, and ensure they have full thread engagement and are engaged to an equal length so you are pulling squarely. Is it Loctited on? If you suspect so you need proper oxy acetylene gear, a BIG rose bud torch tip on a BIG torch and add a LOT of heat to the hub, very FAST or you will heat up the front seal. Probably best to change it if in any doubt. Heat will render the fitted damper as scrap. Quote Link to comment Share on other sites More sharing options...
berg Posted March 7, 2016 Author Share Posted March 7, 2016 Thanks for the advice guys I think heat is going to be my only option here now I drilled the holes out and tapped to 10mm and used 2 heavy duty socket cap bolts Same problem, using the same method Scooter mentioned above and its pulled one of the bolts out along with the thread from the hole Both were lined evenly etc Quote Link to comment Share on other sites More sharing options...
