Wrist pin removal

Postby J_ROK » January 25th, 2006, 9:19 am

I'm having a problem removing a wrist pin from a damaged piston.Removed both jugs. The one that wasn't damaged the pin moves freely but the other one will not budge is there a special tool i could get for this? I tried a c clamp didn't work. Its still attached to cam shaft dont want to take lower unit apart. The retaining clips are removed

Good Question NSF69.And thanks for thoughts on the oil.. I found a great web with pictures on piston failure.Even as a retired Mech. I learned a thing.

A wooden dowl and a mallet work well for me.
Recently I was asked to play in a golf tournament.

At first I said, "Naw, I haven't been playing that well."

Then they said to me, "Come on, it's for handicapped and blind kids."

Then I thought...




Chit, I could win this!

Obviously you want to be careful - small hits - but with a mallet (I am meaning rubber)and a wood dowel there is a lot of forgiveness. I guess you have to use common sense - I just assume eveeryone has that and they sometimes don't.

A deep socket just a hair smaller than the pin works good too.

I got the sled for nothing it sat for a couple of years. It started up after a few pulls. didnt seem to respond well to the throttle so checked compression one cylinder held 96# the other 30# so decided to do a rebuild. The boots from the damaged side had a hole at the bottom of it (between carb and jug) the old owner said he had to rebuild carbs every year so i'm guessing he was trying to compensate for the extra air flow and therfore damaged the piston and cylinder. I'm gonna rering the other one. The sled is a Artic Cat Cougar 89 500 air cooled. I picked up a new head, cylinder, piston,etc... for a steal on EBay. Thanks for the info i'll try heating it first.


Can anyone tell me the proper compression range for this model?
