Automatic transmission rebuild, Stuck shaft bolt!

5

Asked by Aug 08, 2015 at 09:04 AM about the 2000 Honda Accord LX V6 Coupe

Question type: General

Hello!  I am working on a 2000 Honda Accord LX V6 3.0 Automatic transmission.
B7XA transmission. I have no issues wih the rebuild itself, but I have encountered an
issue removing one of the three shaft nuts, placing my rebuild at a hurdle.  This nut is
not a reverse thread, I have tried PB blaster.  I do not mind replacing the shaft itself,
so damaging the shaft is not a concern to me.  It is a 33mm nut pictured, circled in
red.  Any ideas for removing a stuck bolt, likely held at high torque ratings.  P.S.  I
have tried Impact gun (electric and pneumatic) with no success.

You ca: 1 - Try a 3/4" breaker bar and socket with a 4 foot long pipe over the handle of the breaker bar for leverage, or 2 - Use a torch (oxy- acetylene) to heat the nut/shaft end until bright orange, then hit it with WD40 or PB and them try a standard 1/2 or 3/4" breaker bar with or with out the pipe for added leverage.

JP1956 the oxy-acetylene is a way bit too much heat .Get a 14 oz can of MAP Gas it comes in the yellow can. Map gas burns hotter than propane but not as hot as oxy-acetylene.Getting the nut so hot that it's bright orange could damage the threads. The use of heat is to make the nut expand but remain strong. It also makes any thread locker let go. What is holding the shaft from turning? You may just need to shock the nut by using a boxed end wrench and a Very large hammer.
