Rear Wheel drive splines

Postby rampal55 » Sun Jun 07, 2015 5:41 pm



Once again I am asking for help. Last Dec. I replaced my rear tire, brake pads, greased all of the drive train, changed fluids, etc. Everything went well as I followed the tutorials to the letter. Thanks to all that post those items. Last week I had a flat on my new rear tire and had to take everything apart again. While I was working on the bike a friend brought over an “expert” on Goldwings or so he said. When he saw my rear drive wheel spline, he told me those were the worse he had seen and that I should replace them ASAP.I am attaching pictures of my rear drive spline and would like everyone’s opinion. I don’t see as much wear as he seemed to see. The bike has a little over 77,000 miles. Also after an hour of talking, he told me that he would not have a problem with me going to Michigan this summer before replacing these drive units. So now I don’t know what to do. Please help… thanks again paul

There is a bit of wear on them - hard to tell - you need some better angled pictures.

As long as there is a flat spot across the top of the teeth I think you are fine. But you can tell there seems to be some wear on the front side of the teeth - there must be some backlash occurring. What does the rear drive unit look like - and the wear on those teeth/splines.

Mine was way worse than that - but I wasn't happy with the amount of rear wheel movement - that's why I replaced the rear flange.

Put the bike on the centre stand and see how much free play you have when rotating the wheel backward and forward. what is the amount of degrees it moves?

Overall I think you are good for any long trip - just make sure it is covered properly with the correct grade of moly paste. :)

When viewed from the end looking toward the center of the hole in the wheel bearings, the splines should have a clean, square profile to them. Yours are not the worse I've seen, from what I can see in the photo, but they are worn a bit... clean them up really good, put some Moly grease (60% or better, I think) on them, and put the bike back together again. Your splines didn't get the right treatment during their lifetime and it would be a good time to be looking for a set of replacement gears to install soon, I think. Who knows, with proper care going forward, they may last a long time.
I am wrong as often as I am right concerning what is wrong with someone else' motorcycle without having seen the machine in person. Guessing with limited information, as to the source of the trouble, is sketchy at best.

Here is a link to my post on the condition of the rear flange when I disassembled mine.

Yours are not the worst I've seen, but they are considerably worn. This is solely due to a lack of lubrication. This is more or less what they should look like:

The walls of the teeth should be fairly close to vertical, and the tops of the teeth should be uniform in width.

Thanks to everyone for all the great information.. Great people and great information is what this is all about. I do have several more questions.
1) I see on ebay people are selling rear wheel drive splines and final drive assemblies. The pictures only show the outer shell not the gear splines inside. Does this mean that it is only the hub or a complete unit? There are very few descriptions about the parts.
2) What years are interchangeable with my 95 gl1500se? Many of these units have no year model attached to description just off 1500.
3)Should I go ahead and replace both splines? I cant really get a good look at the gear in the hub (old guy with bad eyesight lol). I have been told that the part that attaches to the wheel is the only one that really wears out. I find this hard to believe as I am from the old school with chains and gears. If you change one you change them all. Does this still apply?
4) Can you just buy the one gear in the hub and install? If so does anyone have a tutorial? I find the ones on this site are the greatest.
5) Should I bite the bullet and replace the entire drive line? If so anyone have an idea where to find good prices?

Thanks again to all.... Wingman, keep up the good work.....you other guys and girls too... paul

If the wheel splines are worn, it is a good bet that the final drive splines are worn an equal amount. Take a look at them too. Final drives and driven flanges on Ebay are usually east to find. Trike conversions caused an abundance of spare rear end parts. Take your time and look around. You will eventually find the parts you need at a price you can live with.

Just got some information from a long time winger about Bel Ray assembly lube. I was told it was a very good replacement for the Moly 60 lube. I was also told that Bel Ray had been making all the lubes for Honda for quite a while. Don't know how accurate the information is, just wanted to pass along what I have been told....Still looking for replacement rear wheel drive parts... paul

The MSDS for Bel Ray Assembly Lube states that the molybdenum content is only 20-40% - not enough for use as a spline lubricant on our bikes.

Does anyone have a recent copy of the MSDS for Honda Moly 60?

I found a suspect copy on the ST-Owners site. It indicates that Moly 60 only contains 15%-20% by weight. But, that MSDS may not be a Honda Product. It says THREE BOND for the manufacturer. I have yet to find one for Honda Moly 60.

The MSDS for Bel-Ray assembly lube indicates that it has 25% - 50% content.

There is also a Moly made by Loctite that has from 60 to 100% Moly content.

The Loctite product may be the way to go for spline lubrication.

I had a look at mine to see if it specified who the manufacturer was, so I could try to find the MSDS, but was unsuccessful - it only says "Distributed by American Honda Motor Company"

However, right across the top, it does state that it is 60% Moly:

Moly 60 paste
Moly 60 paste


That said, I found some of the original Moly 60 paste still available on Amazon, and just bought some:

http://www.amazon.com/gp/product/B0083B ... ingdocs-20

If that sells out, you might still find it from other sellers:

A little more research and I founds this site: http://www.msdsonline.com/msds-search

They list the Moly 60 Past as manufactured by Three Bond Intl

Though the Honda Moly 60 Paste package says 60% Molybdenum Disulfide it doesn't say by weight or volume.
The Three Bond MSDS says 15 - 20% by weight. This may equate to 60% my volume. Since I am not an expert in MSDS's, I don't know to interpret this particular data. But, if Honda Moly is good enough to use with 15 - 20% Molybdenum Disulfide by weight then I'd bet that Bel-Ray Assembly lube and Loctite are both acceptable as well.

The local Honda shop both stocks and uses the Bel-Ray.

Just wanted to give an update on my project.. Talked to a fellow winger that was driving a trike to ask him about his left over parts... HAPPY DAYS. He still had the parts in his garage and had forgotten about them until I asked.... Got the complete drive system and rear wheel with a fairly new brake rotor for $100.00. I am very happy and satisfied.. thanks for all the helpful information.. paul

That's great. You got an excellent deal, he made some money and made space in his garage. A winner for all.

Just remember to lube those splines.
