Checking your Drive Flange Bearings on your ST1300
Here is a pictorial for checking your Drive Flange Bearings on your ST1300.

Photo 1 Ice pick method to remove large Snap Ring.

Photo 2 Screwdriver method to remove large Snap Ring.

Photo 3 Snap Ring pliers is the preferred method for removal.

Photo 4 Carefully work ring out of grove. Do not force or bend.

Photo 5 Snap ring removed

Photo 6 Clean off spline with rag.

Photo 7 Lay wheel over about 2 inched above floor and gently drop on floor. Flange assy will come out.

Photo 8 Flange assy out of wheel, laying on floor.

Photo 9 Flange assy with rubber drive cushions

Photo 10 Check bearing by turning with your finger. Should be smooth turning.

Photo 11 Check other side the same way.

Photo 12 Inspect O-ring on Wheel.

Photo 13 Inspect O-ring on Flange.

Photo 14 Inspect rubber drive cushions

Photo 15 apply Honda Molly to wheel bearing face.

Photo 16 install Rubber drive cushions in wheel

Photo 17 Lay wheel in your lap so as not to damage disk and install Drive Flange into wheel.

Photo 18 Install snap ring into grove in wheel.

Photo 19 Inspect and make sure snap ring is in grove all around wheel

Photo 20 apply Honda Molly to Flange Splines in preparation for reinstallation of wheel on to rear drive.


This whole procedure takes about 15 to 20 min. to do. It is well worth the piece of mind. My bearings were good this time. Next time if they are bad I will do a bearing replacement episode.

60k and I have changed the two Flange bearings 3 times. I now check them at every tire change.

In your caption for Pic 15 you said, apply Honda Molly to wheel bearing face....

Is that the correct grease for that application?

Thanks

The manual doesn't state that's necessary.. but I can't see where it would hurt.

On page 16-10 2003 Honda Service manual, about 1/3rd of the way down the manual states.... "Apply 3g of Molly disulf paste to the mating surface of the rear wheel hub end and final driven flange A."

This step should be before.... "Install the driven flange assembly to the right wheel hub."

The manual sequence is wrong. My thought is these pieces will have a slight bit of movement against them self as the rubber dampers flex. So the requirement for Molly. I hope this clears it up.

Thanks Chuck, that's page 16-11 on a 2003-2007 Service Manual. I think the confusion is the picture is of the assembled wheel.

Re: Checking your Flange Drive Bearings

Are the Honda bearing remover shaft and bearing remover head tools needed for this job? Do you also need the driver, attachments, and pilot tools? Or do you improvise with something else?

For checking no.

For Changing, I improvise by using deep well sockets and a rubber mallet. Next time I have to change the bearings I will do a write up on changing them.

Re: Checking your Flange Drive Bearings

The initial post was most helpful!

FWIW, my bike has ~10,600 miles on it, and the bearing on the drive flange side was 'chunky'. Upon removal, (I had replacement bearings on hand for comparison) the outermost 6509 bearing was the culprit, and it clearly had experienced high heat.

Thank you.

By the way, I ordered the Honda tools for bearing removal, and it's the old adage -- with the right tools one can move mountains.

They weren't expensive, so the peace of mind was worth it in my case.

Just ordered 10 Bearings....$29.95 vs. 2@5.95=$11.90

+1. My bike had 11,800 miles on it. I can't remember whether it was the inner or outer of the two Final Drive Flange Bearings that was burn't/toasted - probably from experiencing high heat. I also ordered the special tools and should have them in 4 weeks since they are on backorder.

Right tools? The rear bearings are simple to replace.

Joe:

You are absolutely right. No special tools are needed. I did read your terrific thread before doing mine. I was able to pop out "Collar A" by putting the axle through the Collar and tapping it only once lightly with a rubber mallet.

To reinstall the bearings I didn't have a large enough socket so I used the old bearings and a pipe to keep it centered.

Given that an imperfect insertion of new bearings could be the cause of the problem, I wanted to have the right tools on hand for the insertion of the bearings. I want to ensure they go in perfectly and in prestine condition. Plus I wanted the tools to remove the other wheel bearings too since I know I'll be doing lots of highway miles on this ST.

I understand completely. So far, mine have looked great at every tire change since. I've put 10,000 additional miles on them.

If you still have a set. I will get them from you at TexSTOC. I just checked mine last week. No problems yet. Would like to have a set on hand though.
