Swing Arm Bolt Removal

Post by Steverino » Thu Feb 12, 2015 10:49 pm

Hi Everyone
I did a little gentle tapping on the swing arm bolt and it showed no sign of moving. With my CB160's I just wail away to drive the bolt out but the CB77 has those alloy brackets that are prone to cracking and I don't want to put a mallet anywhere near them. Thank you in advance for your help.

You should be able to pull one alloy bracket away and expose the bolt. Pump grease or oil through the greasers and apply heat. Let it cool, and repeat. Remove the grease nipple, replace the nut backwards and start tapping, via a soft drift or piece of hard wood.

If it doesn't budge, repeat the above. Try and get some heat / penetrating oil into the centre part where the pin goes through the frame.

Remember the three Ps --- Patience, Patience, Patience.......
