I have not done it on my 1500, but I did do it on my 1100. All I did was layed the bike down on the right side on the grass so that the oil level would be below the shift shaft seal and then just pryed out the old seal and pressed in with my fingers the new seal. I was surprised how easy it was. Hardest part was lifting the bike again. LOL Whole job took less than 15 minutes. I would imagine the 1500 would be very similar.

Although not a video, there are a few photos that help in combination with what is written, here.

I was able to change shifter seal on my 15 without removing anything other than shifter. Has to grind just a little off of shifter when reinstalling. It is tight but doable. I had my bike on a lift, probably a lot more difficult with bike on ground. Used a pick to get old seal out.

you may have other problems.Some 1500's have a loose shaft.Every time you use the lever,it moves the shaft far enough that the seal has a gap and a drop of oil escapes.
there is a upcoming mod for this and it should also improve the shift action.
a search of "loose shifter"will get you more info

Just wondering if you have a heel/toe shifter. Heard they are hard in the shifter seal.

It is more work on the 1500 than the older models, but it isn't so horrible.
You really need to consider installing a "shift shaft stabilizer" which you can read about from its inventor here:

Keep the rubber side down.

The seal is a little difficult to get to. Removing the lower shield is a start. The bolt retaining the shaft can be gotten to with a 10mm 1/4 in universal. You will have to use a pry bar to push the engine further to the right in the frame. Be careful. You will still have to work at getting the shaft off. Once the shaft is off grind the section that contains the bolt at an angle to make reinstallation easier. Don't worry there is plenty of meat there. It won't be a problem. The seal comes out pretty easy with a pick. Careful not to nick the shaft or gouge the aluminum seat for the seal. You will end up with a bigger problem if you nick the shaft sealing surface. I have the pivots all made up to correct a loose shaft problem. Send me a PM. I think every one of this model run has this problem. My 14400 mile 2000se did.

When I first serviced my 88....50k miles..I found this...oil coated engine and exhaust..Yuk..


My older bikes never had this kind of leak,I had to find out why...It seemed inherent in the 1500's.
After I removed the seal,This is the source of the problem..


Replacing the shaft and bearing would be time consuming and expensive,not to mention,it may not improve the issue..So I replaced the seal and "secured" the end of the shaft to eliminate the "end shaft play"
Stabilizing the shaft my any means yields great improvements...Even if it's just to eliminate the oil leak..
Special note...My method is different than what's going to be available I'm sure,but the results should be the same...

End results...Stabilize the shaft...stop the oil leak....improve gear selection...It doesn't get any better than that....

Virgil showed you a nice alternative to my pivot. He made a great repair that does the same thing. If money is an issue it can be done with a bearing and some epoxy. It will work.

It's not my intention to show an alternative but only to show why there is a oil leak,a loose shift arm and what could be done to improve it..
Obviously mine is a handmade conglomerate of many parts and was intended for a show and tell only.

Kudos to peppilepew for design engineering and building a mod available to all...you did well. :D

I know Virgil. Sometimes a little extra work is in order when someone doesn't have funds. There isn't allot of discretionary funds out there right now.

Thanks for all the info. I do not have a heal toe shifter cant stand them. I will do a search on the loose shaft. Mine has a loose one I checked it. Its a 1996 with approx 76k on it

I think they are all loose. Not enough support surface. In other words the bearing is too small to support the load. The oil leak starts when the seal is constantly flexed in an egg shape. Once the seal becomes aged and hardened from heat it cracks and accelerates the small leak into a big leak that spreads onto the exhaust. Honda either missed it or let it go because of costs to re-engineer. My pivot carries almost all the load because it is located close to the foot lever. The bearing in the crankcase becomes more of a centering support. Most just have the seal replaced to find it leaking again in a very short time. 100.00 plus wasted on parts and labor.
