Differential oil seals

Post by antonyhoch »

Hello fellow Goldwingers. I have a 1990 1500 with a leaky diff.The correct part number is 91265-MG9-003. The seal is 65x85x7
Part number 91265-MCH-003 is also a 65x85x7 oil seal. Is it fair to assume these are identical, or will they likely have different profiles?

I wouldn't take a chance on this one. The GL1500 is not listed as a bike on wich this part would fit on partzilla, so for me that's a no go
Most motorcycle problems are caused by the nut that connects the handlebars to the saddle

Te difference is the MCH seal is for a final drive on the left side so it is made for the opposite direction of rotation. Believe it or not it matters for some seals.

Is there a differential on the left hand side?

I just replaced all the seals and O-rings on my 1990. The seal I got from a Honda dealer was 91265-MY3-003. I also got a 61302-MA6-003, 91281-ME9-005 and 91358-MG9-00?. Those are from the bags as I can't find my receipt right now. I remember one of them was obsolete and replaced with a newer one. I also replaced the O-rings and the seal for the driveshaft while I was in there.

As DaveO430 stated, some seals are directional but they would have ridges on the sealing surface, a seal with no ridges would not be directional. The ridges help keep the oil in as the shaft rotates, putting a seal with the ridges in the wrong direction would actually pump oil OUT. Again, a smooth seal should not be directional.

For a '90 Wing, BikeBandit shows a 91265-MG9-003 but it also shows it unavailable. The seal I got, 91265-MY3-003 is listed for a '93 Wing.
