1984 Goldwing 1200 Interstate Rear Drive Bearing Problem.

Post by Badgolfer88 »



Hi. I am from New Brunswick, Canada.I bought a 1984 Goldwing Interstate knowing that the rear drive was very messed up. The bike ran like a dream,but you could not take it for a drive.Some of the 1984 ,1200,s managed to have inner wheel bearing bore made slightly too large for the bearing that was being pressed into it. The bearing requires a.002 (check with machinest)interference fit to work properly.Once this bearing outer race starts to rotate in its housing it allows the 24 tooth (male & female)drive spline to wobble and eat the teeth off of each other, therefore bike in gear,and going nowhere.Rear wheel has to be removed and taken to a machinest who will bore out bearing housing in wheel and put in new metal ring to replace removed material. this ring is bored to spec for a new original bearing as the oversized ones mentioned in this forum do not exist.This will now have your back wheel in order.Now you now have to replace rear drive (complete)as it has the male part 24 tooth spline and the female 24 tooth spline where drive axle makes 90 degree turn to your back wheel.There are still some available on Ebay and elsewhere for $50-$100.00 us. Put new drive spline on and considering you have everything relatively to original spec,you can get your couple hundred thousand miles as was originally intended. I put this fix on mine and have put 6000 miles last year and the bike is working like a dream including better than 45mpg hwy driving.

What does the machinist cost for his part?

Or one could swap to a 1500 rear wheel / brake with a better supported double row drive side rear wheel bearing and forget about it. One could also use the 1500 FD as well as it has same ratio.

It's not so much that some had oversize holes for the bearing, they weren't shipped "loosely fitted". It's a matter of inadequate support and miles and pounding and loads that expands the area around the rear wheel's drive side bearing.

Yes + one for CP. I went the machinist route. My wheel hub was .015 over at the bearing bore on the FD side! Drive spline and FD were good? My bike is the SEi so that problem was supposedly addressed by Honda in 85. Still did not hold up. My bike had 44,000 miles when bad hub was found. I paid the machinist 140 bucks to do just as you said. He used a vertical mill due to size of wheel but a big lathe would be quicker/cheaper. Mine seems to be fine now. I used an additive called Molly Slip in the FD when reassembling, not that this has anything to do with the hub, just sayin. Glad it's workin for you BG88...Rusty
