GL1200 Caution Rear Wheel Changed For 1986

Postby steveybee » Tue Mar 01, 2016 2:37 pm



Others may have come across what i have experienced with later GL1200's Rear Wheels + Drive Flange.
I needed to Change my Final Drive on my 1986 GL1200 SE-i due to excessive backlash through poor maintenence by a previous owner:
This is my Experience:
After removing the rear Final Drive & Drive Flange from my bike then fitting the one i bought which was from a 1985 LTD model all was fine until it came to fitting the drive flange / spider to the wheel itself, it wouldn't fit what was preventing the drive flange from fitting i found was the register on the the wheel which surrounds the wheel bearing was a larger diameter than the one i'd bought preveventing the drive flange fitting over the register diameter.
I compared my old worn out flange with my newly aquired one & imediately noticed the difference. Having one or two really good drive flanges for my 1991 GL1500SE i checked one of those with my old GL1200 flange & they where both identical dimensionally & shared the same part numbers so i fitted 1500 flange to my 1200 & everything went together & worked exactly as it should.
I later start checking Hondas parts lists out of sheer curiosity & the GL1200 Drive Flange changed for 1986 along with drive side rear wheel bearing which is larger in diameter & possibly wider if my memory seves me correct.
This 1986 GL1200 Drive Flange change continued through to at least the 1991 GL1500 range.
CAUTION:
The real danger i can see is the fitting of the later drive flange being fitted to an earlier bike / wheel as the larger diameter machined for larger rear wheel register will fit over the smaller register on earlier wheels therefore totally relying on the drive pins for location.
I've mentioned this to about a half a dozen or so Goldwing Specialists only to be told that i'm wrong we work on nothing else & have done for years they are all the same with no difference whatsoever, i then mention Honda Official part list to them with different part numbers for the wheel & drive flange to be told i've got it all wrong.
The sheer arrogance of it all, i eventually bought an early GL1200 rear wheel so i satisfy myself & yes it is different.
If you need to replace a drive flange & final drive unit due worn out splines make sure the drive flange is the correct one for your wheel, the alloy final drive unit that some call the differential which it simply isn't, that's fine as it's the same + i believe it also fits up to 1991 GL1500's also.

Keep in mind there are two different types of GL1500 driven flanges: 5-pin and 6-pin:

The 1988 and 1989 GL1500 have six pins, the 1990 and newer GL1500 have five pins.
