Swing Arm Bolt Removal


Recommended Posts

I had to take the swing arm off to install a new chain slide. My first attempt was to use a soft mallet to tap it out. Didn't budge. Worked my way up to a 10 pound sledge and a chunk of wood to protect the threads. Fail. I came on this forum last night and found some old threads. Sounded like the air hammer was the way to go. Bought one today it cost me about 25 bucks. It came with chisels and a punch. I took a die grinder and cut off wheel and cut one of the chisels so it was just round stock.

My next attempt was a success. I was very surprised it came off so much easier. The air hammer is the only way to to do it. I saved the bolt, threads were okay... I had to file some of the threads to clean them up. Reinstalled it and going up riding in the morning. I installed a new EK chain, TM designs chain rollers, TM chain guide near the sprocket, and a cascade chain slide that I had to remove the swinger to install. Not as bad as it sounds to remove. Bearings in the swinger were still good.. I didn't mess with them just put some grease on them. BTW I used a socket extension to push the bolt out once the air hammer couldn't reach.

Rappy, what do you even know about lube? Not the greasy shit your mom uses on the rectal thermometer to get your temp when you feel sick to your tummy either. And note for everybody, always spit on it if you want them to come back. Otherwise, just shove it in there.
