Hi guys, I'm having troubles removing the old fork seals.... The forks are in bits so don't worry about that, I'm just having troubles removing the seals themselves, any ideas? heat guns? levers? hacksaw? man this bike likes to make things difficult for me!!!  Thanks! |

My Haynes manual states:
"The oil seal fitted to the top of the lower leg should be removed only if it is to be renewed, because damage will almost certainly be inflicted when it is prised from position. The seal is retained by a spring clip, under which is fitted a large washer".
You might go to a Yamaha Dealer site for OEM parts and see the exploded view of the parts diagram.
Good luck!

Assuming you have removed all clips, etc. holding the seals in place. Go to the hardware store and purchase a new (small) wooden hammer handle. Shape it by what ever available means to something that looks like a large straight blade screwdriver tip on steroids but without shape edges. Jam it under the seal and pry it out. You don't need to be gentle.  Save your "Special tool" for the next time you need to pry something without damaging the surrounding surfaces. Good luck PC |

I'd still be a little careful pushing the round screwdriver shaft against the top of the fork to prevent any deformation...do it reasonably carefully in my opinion and it will come out with no damage... SR  |

the way i remove this style of seal is to place the fork on a wood block on the floor, sit in a low chair and with a blunt screwdriver and hammer hit squarly in the middle of the seal from the top,and work my way around the seal.this will colapse the seal away from the fork lower and lessen the chance of damaging the lower.work slowly it's ez to damage the outer edge if you start prying on it!
hope this helps,Bob

I chickened out and took mine over to K&N Yamaha. Just had 'em polished and decided not to risk it. They have a seal-pulling tool and want the top halves brought over before they perform the seal change.....likely to charge me next to nothing for the trouble. I don't let my pride get in the way on these kind of things......I've learned the hard way too many times! Ya gotta know your limitations...............

I heated the lower legs with a heat gun until it was just uncomfortable to hold for more than a few seconds. Then I used a large screwdriver with a thinnish piece of hardwood as protection for between the shaft and leg top. Worked well... I also used heat to get the new ones in, pounded them carefully in with a plastic mallet and the old seal as a pusher.

Thanks guys all done. I ended up using the technique Miker mentioned but instead of the thin peice of hardwood I used a paint scrapper. Worked a treat, though one was a down right pain in the back side. Now to the painters they go!
