I'am trying to get the (new) seals installed in fork sleeve nuts(new).I have tried over and over to get them started down in the sleeve nut to no avail.I'am beginning to wonder if they are the right size.Are these seals this difficult to get started?Any suggestions?
If I remember correctly, they need to be tapped down with a large socket or something like that. They should be a tight fit, and the large washers go above them. Can you check the part #? There's always the very slim chance that the wrong ones were put in the box.
Hope this helps: Jim

The numbers match whats shown in the parts book.Unless the seals sent were wrong as there is no number on them,that I can see.I've had better luck putting in bearings then these seals. I guess if I can get a micrometer and measure the seals "OD" and then measure the "ID" in the fork nut with a snap gage I could figure out why they won't start.Just got to get my hands on measuring devices.
If you don't use a properly fitted drift, youll ruin the seals before you damage the cups. Remember, the seal goes in from the BOTTOM of the cup, and is held in as a sandwich between the top of the fork leg and the shoulder inside the cup.
Take a wire wheel and thoroughly clean out the inside of the seal cup before attempting the install. Squirt with WD40.
A large wooden dowel with a giant flat washer up against the seal makes the best drift. Set the seal cup SQUARELY between the dowel and a flat piece of lumber such as 1x4, press them together with your vice. Eyeball the assembly every 1/8 turn of the vice arm, and make sure it is seating properly.
GP: no offense intended, naturally, but my parts book shows the seal going in from the "upper", i.e. spring, side of the cup, with a washer above it. That's the way I've always put them in.
Maybe I just misunderstood what you meant: Jim

It does go in from the upper.I got them in yesterday using a large washer and piece of black iron pipe that fit inside the sleeve.Thanks for everyones help.
There you go a 5 minute job. Never bash in any seals as they will only go in crooked, always slowly with a vice which again is a good way to put in the crankshaft oil seal in the timing cover, points seal you can push in with your fingers.
