2006 1800 oil leak

Postby onelostsock » Sun Jul 07, 2013 1:03 pm



Could anyone possibily tell me what the part is called in the rear end of an '06 Goldwing that is on the bottom of the final drive unit(?) near the lower drain plug for the rear gear case. It is a dog bone shaped piece of metal mounted with 2 hex head bolts to the bottom of the case. The bolts appear to be mounted through rubber grommets or something similar. I have gotten a small leak through one of the seals(?) or grommets and have seen gear oil on my rear wheel 2 times now. The weather here is hot lately(90) at the moment and was wondering if it is just a function of the hot weather and oil seeping out. Are these things easily repairable and available? I can not seem to find a micro-fiche parts picture of the thing so I don't even know what to call it! Any help would be greatly appreciated.

I believe the part you are talking about is actually on the drive shaft housing. If this is the right part there should not be any oil in the drive shaft housing.

Have you taken the bolts out ? I don't know if the bolt holes go all the way thru the wall. If you take the bolts out and you get oil leakage you have a bad seal in either the final drive or the motor at the drive shaft. If you do you maybe able to tell which by the thickness.

Thanks for the reply jinx. I did call American Honda in California and was able to find out from one of their tech experts that the part I am speaking of is actually a harmonic balancer for the driveshaft. And you are correct in assuming that it most likely be either the differential seal in the rear or the engine end seal.(That part of the swingarm is dry) Hopefully it is the rear seal because I believe the labor rate for that repair will be less. At $80.00/hr at our Honda shop it adds up fast. Bums me out though because I only have 16,500 mi on the bike.But if you want to play you got to pay!! Happy riding!

If you have the ability you can get a trike take off on ebay for around $100.00 .
If you get lucky you can find one with the disk and caliper.
Many of the take offs are new and I have a take off on my wing, went out at 145,000.
