GL1200I output shaft oilseal replacement

Postby Detenator » Fri Mar 22, 2013 2:26 pm



Does anyone know if I can replace the output shaft's oil seal on the rear engine cover without pulling the motor out of the frame? Thankx!
I have a 1986 GL 1200 Interstate.

I think this could be done. But I was wondering if anyone has tried this before? I seems like I should be able to remove the rear wheel and unbolt the swing arm, pull the u-joint back and out and expose the output shaft on the rear of the motor. This shaft would know be smaller than the ID of the seal. From the parts list diagrams it appears that the seal has a lip on the front side and slips in from the front. Move the clutchline. Its seems like I should be able to pry to old one out with a flat screwdriver or a putty knife. I could then make a sleve from a piece of pvc pipe to slide over the output shaft and press the new seal in place. What do you think of my plan? If no one answers soon I am going to try it.

I find it hard to beleave that this question has had no comments. With so many people on this site no one has had a leaking output shaft seal before? You guys jump all over the easy ****. I ordered the part today and I will try my procedure to see if it works. Sorry I picked so hard of a mechanical issue for you to tackle. Guess its a good thing that I have a strong mechcanical back groung. I am disappointed that site seems to be of no help on this subject.

I just noticed my output shaft seal is leaking oil as well so here I am looking for the same info as you. The manual says to remove the swing arm but I think you can just remove the final drive unit, pull the drive shaft out and seperate it from the universal joint, get it out of the way and that should give you enough room to get at the output seal. Manual also says you MUST replace the oil seal that the drive shaft goes through at the end where the final drive unit bolts on. I don't have the time right now to take mine apart and will not get to it for a few weeks so let me know if you get to doing yours and how you make out.

Thanks for the reply. I ordered the seal yesterday should be here by the end of the week. I will post up how it went. Where is the second seal that you speak of? Is it the one on the final drive side of the universal shaft? I did not see any thing in my clymer manual ecept for one sentence. Which says "Install a new dust seal into the receptacle in the engine rear cover where the output shaft exits the cover" then it goes on to say install the engine into the frame. which means they pulled the engine. What manual are you using?

It is a Clymer manual. Page 338, Figure #22, part list # 14. Top of page, first sentence #9 : "Replace the seal on the drive shaft. The oil seal must be replaced every time it is removed from the drive shaft."
Looks to me once you remove the final drive unit, on that end, you pull out the drive shaft and this seal is there or it comes out along with the drive shaft. The universal joint will seperate from the drive shaft and it should then be able to come out the front side or shove it deeper back to get it out of the way.
Just took a look at mine and it looks pretty tight around there. Once if you get the rubber boot out of the way it looks like it is still going to be a tight fit getting at the seal?????
The manual does say to remove the swing arm assembly but that is a lot of work. It sure would be nice if you can get at it without removing the swing arm.

Re: GL1200I output shaft oilseal replacement

OK I got off my ass today and changed that output shaft oil seal today. So here is how to replace that seal without removing the engine:
1. Put the bike up on the center stand or on a table.
2. Remove the two chrome swingarm bolt covers.
3. Take the spring on the rear engine cover and the universal joint rubber boot and move it over towards the engine and secure it with a piece of duct tape.Then pull the boot loose from the rear engine cover to expose the universal joint sleeve.
4. Take a motorcycle tiedown strap and on my Wing I have a chrome saddlebag cage. Feed the strap through the rearwheel and attach the hooks to the saddlebag cage. At this point, just make the strap taut.
5.At this point you will notice the 2 swingarm bolts are not the same. The right side is a 17mm socket. The left side has a 10mm allen hole and a lock nut. The Clymer manual states that you need a special tool from Honda (p. 338). I called the dealership and they wanted $111 for this tool! I thought about it for awhile and went out to a bicycle shop and measured a couple of "Freewheel Remover" tools. The one that I found that met the requirements was a Bulletproof Freewheel Remover #61752 for a 14mm axle. It cost $9. The Park Tool FR6 seemed to measure a bit too fat to fit inside the tube. The Bulletproof tool worked perfect for me! For reassembly, I was able to put an inch and one eighth socket over this tool with my torque wrench attached to torque it to specifications.
6. Remove the swingarm pivot bolts. Remember that the threads on the locking ring are left-handed threads and the 10mm allen is right-handed.
7. Pull back on the rear wheel and tighten the strap to keep the wheel pulled back. You will easily be able to pull it back far enough to disengage the universal joint.
8. With a long, thin screwdriver, gently pry the old seal out of the rear engine cover. Make sure to work in small increments and try to work all the way around the seal. I did end up bending the outside lip of the seal that I was removing but it didn't matter since I was removing it anyways.
9. Once the seal is free, remove it from the output shaft. Take some molilithium grease and coat the splines of the output shaft.
10. Take the new seal and give the inside lip and the outside lip a nice coat of grease. I also greased the lip inside the rear engine cover.
11. Take the new seal and slide it over the output shaft slowly and push the seal in by hand...as far as you can. I then took a fat, flat tipped screwdriver and gently pushed the seal into place. Make sure the outside lip is flat all the way around the rear engine cover.
12. Line up the universal joint sleeve to the output shaft. Release the tension from the strap on the rear tire. The universal joint to slip right over the output shaft and right up against the seal.
13.You will be able to move the swingarm around and line it up. I started the left pivot bolt then went to the right side and installed the right side pivot bolt until it was snug. Then I went back to the left side and screwed it in until it was snug. At this point I torqued the right side to the specified 100 foot pounds. I then torqued the left side to the specified 17 foot pounds. I then installed the lock nut on the left side with my Freewheel Remover tool and 1 1/8 socket to the specified 100 foot pounds. Reinstall the chrome covers.
14. Reinstall the universal boot over the lip on the seal that you just replaced. Remove the duct tape and slide the spring back into its groove on the universal joint boot.
15. You're done! Go ride!

I am sorry I miss quoted the torque specs. The correct specs are Right hand pivot bolt 72lbs., left hand p[vot bolt 14lbs.,pivot lock nut 72lbs.
I redid mine and made sure they were not over torqued.

Hey, Thanks for all the info. My seal is really starting to leak now so I guess I am going to have to get to it sooner than later. I just ordered the Bullet Proof Freewheel remover that you mentioned. Now I have to find the seal.

I use bikebandit they price match oem prices, and delivery is quick. This task is super easy and will only take 20-30 minutes to complete. I wish all repairs were this easy. 8-)

Nice job, Thanks. I orderd the tool mentioned. Always great when we can find a substitute or make our own. I know I will have to take my swing arm off one of these days to replace bearings due to mileage or just age. Or even a rear seal.....
Enjoy the ride. They are all good, just some better than others.

The statement saying that the "locking nut was left handed and the allen head pivot bolt is right handed is incorrect. They are both right handed and can be no other. How can you screw a left handed thread onto a right handed bolt? This incorrect information has caused me considerable frustration and time.
