I had rear tire changed and oil and final drive oil changed recently. Shortly afterwards I noticed final drive oil seeping out where the final drive meets the shaft cover. I checked the final drive oil and found the dealer had overfilled it(mechanic told me that they fill it upright and not on the stand). The seeping oil has slowed down(its been about a week)since I drained the oil but still leaves enough to wet my finger tip after every ride. My question is how long should it take to clear out any residual oil(days,weeks,months) or are the seals damaged once there breached. Also how hard is it to replace seals. I already posted this last week on 1300 board just checking here because there are alot of knowledgable people here that don't read 1300 and wondered if any had same experiance. Thanks
final drive overfill?

Breather caps clean. It started right after dealer over-filled final drive oil. I was just wondering if anyone else has had thi happen from overfilling and does this ruin the seals or is it just residual oil from oever fill slowly leaking out. If its not going to stop I will replace seals but was wondering what seals I should order and how hard are they to replace. I don't have a lot of faith in my dealer right now.

It should not leak at all from any of the seals. There are two seals up front on the final, and one seal on the driveshaft. You need to find out where the fluid is leaking from.............ie, the final itself or the coupler joint where the driveshaft mates up....................piacovo said:
If it is just leaking from the driveshaft seal, replace that seal. If the hub itself is leaking, there is a seal on the spanner retaining nut, along with an o-ring.
Over filling most prolly did not cause this, unless it was way way over filled to the point of being full. An extra once or two would not have caused this................................
You will need Hondas special tools to pull the coupler and retainer off the hub...............................
Hope this helps,

Thanks for the information that helps. Is it possible to have it leak at the driveshaft connection from overfilling fnal drive without damaging the seals. Is there anyway for oil to get there from overfilling it. As you can see I'm hoping not to do this unless I have to and the amount seeping out each ride is very small now.

Check the torque on the 4 nuts that attach the final drive case to the drive shaft. Mine spontaneously starting leaking at the junction of the final drive case and the drive shaft, as part of trying to figure it out I took off the rear wheel, loosened the 4 bolts, wiggled the final drive and then torqued to 47 lbs-ft as specificied in my VTX 1800 C manual. Put everything back together "voila" problem solved. Then I drove 2,880 of the hardest miles ever to the VTX Gathering in Asheville without losing a drop of final drive oil.piacovo said:

As stated in my first reply, there is no seal at the swingarm to hub connection. Only on the driveshaft itself, and on the hubs coupler. If any of those 3 seals are leaking there, fluid will start entering and accumulating inside your swingarm. Maybe buy tightening up the acorns on the hub, you are providing a metal to metal seal and holding the fluid from leaking out and down.................................piacovo said:
The hub should not leak at all.......................................period.

I guess I should order all 3 seels and the right tools before i open it up. I don't want a lot of down time. I guess if its leaking out of the drive shaft/hub connection tighting up shaft cover will only hide the leak at best and it will continue to leak into the drive shaft cover even if it doesn't drip out and that can't be good. thanks
Is the drive shaft seel stopping final drive fluid from leaking. On the HDL oem online order fiche it looks like the oil seel is at the opposite end of the final drive on the 1300. I'm trying to figure out the right part #s to order. Thank

Yes, the picture of the fisch is misleading. That seal gets installed down at the spline end of the shaft that mates up with the coupler. That seal actually fits inside of the finals coupler....................piacovo said:
The driveshaft seal, seals the drive fluid from comming out of the coupler on the final drive. The coupler has two oil passages drilled deep in the coupler to provide lubrication to the end of the driveshaft and the splined coupler..................that is most prolly where your unit is leaking.
Now, the spanner retaining nut on the finals front end, has two seals on it. One is a press in oil seal that seals the coupler as it is spinning. The other seal on the spanner is an o-ring which provides the oil seal for the spanner retainer when that retainer is installed and torqued to specs. Those three seals are the only place on the front of the hub that would allow any leakage.
Hope this helps,

Thanks Showtime now it makes sense. So I take off final drive and replace seal on the end of drive shaft that goes in the final drive. Does the shaft pull right out of final or are there some tricks to install. I am going out to sears and buy a jack today anyway so I would like to try and do this myself but don't want to get in over my head. Thanks again
