Mag seal leaked and took out a cylinder
Parts and manual on the way. In the mean time how far do I need to tear it down?
Am I going to have to split the case for the seal? or do I just pull exhaust airbox and carbs so I can get at it?
First time for me so any advice appreciated. I ordered skidoo parts from the local dealer.
TIA

you will have to split the case. You will need a puller for magnito.

I would replace the pto side seal as well while you are in there. check all the bearings for misc. crap that may have found its way there when it went down.

if your budget allows, I would do two piston kits as well, then you will have a fresh rebuild.

Here is a site you can save yourself some money for the isoflex grease.

X2 on doing a complete tear down
I would also replace both seals ,check all bearings and install new isoflex grease on bearings. Also install 2 new pistons ,rings etc.
FYI- Watch out when pulling the pistons off the rods the old piston bearings will fall out be sure and use a towel over the cases . Don't want any to get into water pump .

order the caged wrist pin bears when you do the rebuild.
