Stuck Bolt Assembly Screw

[RC20]

Congratulations!!!!!.

I will leave it to the longer time members to be definite, but that strikes me as the mother of all bolt screw problems.

That's great, glad to hear you got it apart! Incredible that someone managed to tighten it that much to begin with.

Those fine threads, large shank and varnish produced by many cleaning solutions can make a BAS hard to remove. This case is WAY beyond anything I have experienced. Floor jumping and all that and hammer striking are no substitute for an IMPACT gun. On any fastener the BEST removal tool is an impact. If you don't own one......you should. Even the battery powered units will make a tough job easy. Long levers and heat are no substitute for IMPACT. Don't beat your head against a wall or your hands or feet against a bolt. Any mechanic shop on the planet has multiple impact units and will probably remove any bolt or nut out there for FREE if you are nice or a 6 pack if not. When you don't have the proper tool for the job and millions of other people do.....get some help.

Good to hear !

Anytime you succeed in a very hard task you learn and gather more experience for the rest of your life !

Hardest bolt I've ever removed was on a crank pully / harmonic ballancer on a 3.0L Chrysler minivan. Heated the bolt with a torch for more than 5 minutes. Then it took 2 of us and a 6 foot breaker bar.

Changing the broken timing belt was the easy part compared to that crank bolt.

I have found that a 3/4 impact removes most everything I need to work on.

The key to the impact working though is it has to be totally secured. If there is any give it absorbs the pulse and will not work.

Axles and engine even on the crank have enough inertia resistance that it works.

Getting a bolt completely secured/locked in place not so easy!
