'79 gl1000 frozen lower front motor mount bolt.

i do belive the front lower motor mount bolt has a nut on both sides and the threaded part is a removeable stud. it is removeable by slideing it out , or in your case braking it loose to slide out. pb is good. but you will have to use a mallet to get it to start to move and soak some more before it comes out either the right or left side. yes they do get stuck good too. hopes this helps.

This one is a bolt, my rider is as you said. I have been whacking it with a mallet with the nut loosely fitted on the threaded end and may have moved it about a sixteenth. I started with the PB and have switched to Liquid Wrench. I'm thinking about laying it on it's side maybe gravity will help. Thanks for your reply.

It is a long way through there and penetrant will probably never make it all the way through. A BFH and a rod to drive it out with is probably the only way.

+1 on the BFH

Any form of heat you can apply will help.

I have a propane torch and a fire extinguisher. :smallpopcorn:

You also need a properly calibrated BFH.:ROFL:

I've been using the blunt end of my splitting maul. :weightlifter:

But have you calibrated it?
Just like a torque wrench a BFH needs calibration.:RTFM:

I need a few more test blows to fine tune the cal setting.:axeman:

:rofl::rofl:

Yep, it's the corrosion of aluminum versus steel...you'll need to use the blue wrench and the Harley Repair Kit to bust it free

Maybye your using a standard instead of a metric BFH.:cheeky1:

I've been kinda easy with the BFH up till now, don't want to flare the end, I do have the nut on trying to protect it.. I thought someone might have the secret answer.

Lay the bike over, clean around the bolt and use some modelling clay or Plasticine to make a funnel. Pour some Magic Mix 50% acetone/50% ATF into it and let it sit.
This will probably still not work; as someone pointed out, it's a long old bolt to get anything all the way down it, but you've the best chance with that mix since the acetone will carry the oil into very small gaps.

Try heating bolt, douse w/water, then more penetrating oil. You may have to do this more than once; have had good luck w/this method.
GOOD LUCK....papasmurf

I will be trying those ideas. Thanks

I'd stick with PB Blaster.The stuff is like acid.If you don't believe me,squirt some in your eye!:wink: Might try squirting,then using an airhose to blow at the edge of the bolt to help penetrate the oil.Wait a while and then a very hard,quick blow whith the hammer.If that didn't work,i would start heating it with a propane torch,then she'll give it up! I wouldn't use an impact 'with an extension',too much flex for frozen bolts to move imo.

That one too! Thanks
