GL1200 Rear Wheel Cush Dampers

Postby Rednaxs60 » Sat Mar 26, 2016 10:59 pm



Have done a lot of searching, reading and trying to find information regarding the cush damper system for the rear wheel of a 1200. I did start a thread on another forum because it was where I found some good, significant information.

There is/was a fellow in Milton, Ontario, Bob Henderson, who did manage to fabricate and change out the cush dampers in his 1200 rear wheel. He put pictures on another forum regarding his work. He came up with a jig that he would secure the inner and outer sleeves to and fill the cavity between the two sleeves with a polyurethane compound. He fabricated an install tool as well. To remove the old damper(s), he would use a hole saw to remove most of the rubber compound and inner sleeve, then he would use a dremel tool to cut the outer sleeve and remove it. When he installed the new damper, he used red loctite to ensure that the damper would not rotate in the damper cavity.

Here are some pictures of an install Bob did:


I have been in contact with Bob and will be travelling back to Ontario to visit family and friends, but I will be stopping in to visit with Bob to get information regarding what he had done. His box of goodies that includes a lot will soon see a new home with myself. I am looking forward to finding out about this from him. My cush dampers are worn - I can see where the wear is when looking at the inner sleeve(s) with a magnifying glass. To my way of thinking, if I can see the wear with a magnifying glass, the power and torque applied to the rear wheel will definitely move the rear wheel to take up any play due to the wearing of the inner sleeve.

Bob also came up with a jig that he used to remove the u-joint from the yoke of a 1200 u-joint assemble and machine grooves so that an aftermarket u-joint could be fitted in place of the OEM u-joint. He installed a modified u-joint on his 1200.

Another issue that he addressed was that the 1200 rear brake rotor is not that plentiful should you need to replace it, and a new one is expensive. I can attest to the cost because I have replaced front and rear rotors on my '85 LTD. He found that the 1100 rotor was the same as the 1200, but the hubs were different. He removed the rotor from an 1100 hub, and installed it on a 1200 hub. He has a rivet install tool for this and the rivets. I have acquired these as well. He has the modified rear brake rotor installed on his 1200.

I am looking forward to getting this equipment home and seeing what is all included, and speaking to Bob about what is entailed and what the expected results can be. This is all the information I have right now.

Further to my previous post, these are pictures of a 1200 u-joint mod Bob Henderson did:


I think this is quite impressive.

Don't know about the buying of his little business. I'm more the "is it there and I'll get it type person". We'll see what transpires. Cheers

Hey Ernest, would you be able to PM me with some contact info about Bob Henderson. I worked in Milton for over 15 years and is less than 3/4 hour drive. The name seems awful familiar, do you if Bob worked at a place called Karmax Heavy Stamping in Milton.
Don't need the cush dampers right now for the 86 Aspy, but I just picked up an 85 LTD as my next project and by initial looks, it might need a new rear rotor. Will also check the cush dampers once apart.
By the by, my daughter and hubby live in Vic, so i'm there a few times a year, maybe I can look you up next time we're out there.
Cheers

In the past, I thought Honda supported their products well. I must have been mistaken. I am surprised that Valkyrie parts are getting scares also. It's a throw away world!! :roll:

I think Honda still does a good job supporting its products, but there are a few major items not available. I have been fortunate to get most of the parts I have needed from Honda, or on the net. I have also searched the net and found a lot of workarounds. I will be looking for specific parts that I may need in the future. I am scouring the net for a suitable "new" u-joint. There are a lot of ATVs and bikes out there that use a u-joint, and as long as it is the right length, and it mates with the driveshaft and engine output shaft, should be okay - have even considered having a new one modified to fit.

We are in a throw away, change it instead of fix-it world. Keeps the industry going.

117,000 Kms - approx 72,000 miles. Wear and tear has so many dependencies - time, lack of maintenance, rode hard/put out wet, and many more.

If you go to a regular drive line shop they can most likely put in a new u-joint. They make drive shafts from scratch for hot rods and 4X4s. They have books with 1500 different sizes of u-joints. They can cut, weld and balance drive shafts. Thats what they do for a living. Take your checkbook with you. ;)

This will be my last choice. Don't have to change it out yet, but looking now in anticipation of the future. I have mentioned I'm a bit of a contrarian, has to be an option out there somewhere. I enjoy the search just as much as the find.

Cheers
