I need to replace the crankshaft seal PTO side on a 1997 polaris indy 500, I know that I have to pull the clutch, can the seal then be pulled out and press new one in, or do I have to disassemble the engine and crancase?
I have replaced just the seal with no problems.Drill 2 small 1/8" holes in the old seal and use a pick or awl to pop it out.Next fill the inside of the new seal with low temp grease and lightly coat the outside lip with RTV silicone.Start the top edge first so the outside lip fits toward the groove and with both thumbs push the seal as far as you can and finish the rest of the install with a 1/2" brass drift(carefully) it takes some patience but saves a lot of work
Just keep in mind if the seal is split it is most likely caused by a failing PTO crank bearing and the engine should be disassembled for inspection,but this will get you back on the snow
