1965 YM1 front fork seals was created by sgarvin0711

I've got the forks all apart, but how do I get the seals out?

I can tell you how NOT to remove the fork seals.
Do NOT use an open end wrench as a pry bar.....

I ended up buying this seal puller from Revzilla.
It worked better than an open end wrench, but you still need to use caution and make sure you aren't using the opposite side of the seal bore as the leverage point.

First welcome. Probably should introduce yourself first.

I think you can use a punch or and screwdriver and knock them out.
Thanks Mark

Morning to you sgarvin0711. My DT250B had a bad LH fork seal leak. Originally I thought I'd use my bearing puller slide hammer tool and this is a good way to remove the bearing as it doesnt put any point loading on the 'oh so soft and delicate' thin seal housing lip. My problem was the tool didn't have a large enough collett in the set (34mm dia required for my fork). The answer (via youtube) was ingeneously simple. Just apply heat, I used a paint stripper heat gun on medium heat. Need to heat top of fork housing evenly and hey-presto after about 10min the seal just wiggled out with no effort at all . No distortion to housing, no dis-colouration to surface. To be honest I was sceptical at first but then amazed at how easy it was. Good luck, and hope this helps, Andy.

Thanks Shu. I will take your advice on the wrench. I don't think that will be a problem though as the seal is situated a little further down in the tube. I will pick up the puller if heating doesn't work.

Thanks for the reply mdscott. I did try that already, but may try it with some heat. As far as introductions... I have a 1965 ym1 that was a barn find and has not run since 1980. I am doing a total restore on it. I've never done ANYTHING like it before, so every step is a learning experience.

Thanks Andy L. Actually, all of the replies were helpful. I am going to try a little of each. I will start with the heat, which I was too nervous to try, but you made it sound ok. With it heated up, I will try pounding it out. If that doesn't work, I will get that puller and try that. I'll let you know how it goes.

"Pounding it out" doesn't sound like a good idea...You may damage the tube.
