final drive O-ring dilemma

Postby aznyaz » Thu Sep 17, 2015 10:03 pm



I'm in the process of getting my final drive to stop leaking and ordered and O-ring (not one that's leaking but one that appears to need replacing).

It's the O-ring that's at the front of the drive right where in connects to the drive shaft. The parts manual and Cyclemax use the same OEM part number for it: 91354-463-003. Reference number is: 36. I received the part today and it's in a bag with the same part number as above but it is much larger than the old on I took off the final drive.

Did I order the wrong part or is it possible the bag is mislabeled? It doesn't appear to have been opened. Anyone ever had this happen. I'll be calling Cyclemax tomorrow.

No, it could be something other than what you need... A package should never be opened like that..I would have laid a freakin egg being so pissed off.

Nope, the package was not opened, I got what I ordered, AND it is not as identified in the parts manual and on the Cyclemax site.

After much research, it was determined that the correct O-ring is listed on the swing arm/drive shaft page as ref. #21, part #91352-463-003. It is another one of many parts that are no longer available, but I was given the location of some shops around the country that show they have this O-ring in stock. Not many around but they're out there, so the correct one is on it's way to me. Now, let's hope my leaking final drive will not leak anymore with my hub oil experiment. I will let you all know.

On another note, but related to my work here, my rear caliper pins and bolts have been seized up for quite awhile and I was prepared to locate a used caliper with the pins and bolts intact (since the pins are no longer available either), and I was planning on cutting the bolts to get them off. I did find one but missed out on the auction. So, I thought about this and tried something. I had not thought of using PB Blaster, thinking it wouldn't do much because I thought my issue was with debris and galling inside the pins, not necessarily with rust or corrosion. I could get the bolts loosened enough to squirt some in, and within minutes the bolts were free. Apparently, it was debris but the PB action helped flush stuff around so the threads would slide by with little friction. After taking the bolts out I just happened to have a tap of the correct size to clean up the threads inside the pins and they work great now. I'm putting the bolts and pins back together with anti-seize compound to avoid this possibility in the future.

Curious, were you leaking Molly 60 grease out of the joint where the differential bolts to the swing arm? I had that problem after the last tire change but I haven't pulled it apart for inspection yet.

No, my leak was out the joint where the final drive and the wheel come together. The oil is basically leaking out of the large seal where the splined shaft comes out of the drive. Oil was mixing with Moly paste and washing out that joint. I was told that hub oil might help to swell the seal to make it tighter around the shaft. The O-ring at the final drive to drive shaft connection was not leaking but it's a little torn up so why not replace it.

Thanks good to know. My leak was excess Molly. I do think I'll replace the larger o ring at some point.

The post above from aznyaz tells a true tale. Reference #36 in the final drive and reference #21 in the swing arm are supposed to be the same part. The final drive reference (60ID x 2.4CS) is incorrect. The correct size is 47ID x 2.5CS.

O-Ring sizes listed in the parts manuals are ring inside diameter (ID) and cord thickness cross section (CS). This site sells cord by the foot...
http://www.theoringstore.com/index.php?main_page=index&cPath=117_537

...and this site shows ya how to glue them up...




Just for a trial, I took a broken ring and glued it back together yesterday evening using Gorilla Glue Gel cyanoacrylate. It worked. I'll be ordering some cord for these final drive rings. Figure for about $5 I can get the leaks stopped.

Anyone else ever try this solution? Could never figure why Honda, largest producer of ICE engines in the world, would use these odd sizes.

Ugh! Further search shows the o-ring store doesn't have a 2.5CS ring in their inventory. Did find the cord, tho, at Fastenal. Gotta love Google.

That's the correct part per #36 on the Final Driven Gear diagram. Doesn't appear to fit anywhere, tho. There's nothing in the area with that large of diameter. I've solved my problems by repairing the ring which goes on #9, 41331-463-000, RETAINER B, BEARING inside the final drive, and making this one (91352-463-003) from a larger ring off an ST1100 alternator which I happened to have on hand.

At any rate, I have all the rear drive components reinstalled and am now working on the front end. New Michelin Activa installed in 130/70-18 size and cleaning up the brake parts. She will roll today.
