I was wondering if anyone has compared the final drive parts of a 1500 and 1200 side by side, specifically the pinion joint coupler and drive shaft. The part #s are a little different but the price on the joint is about $57 different. has anybody looked at them? :baffled:

I haven't compared them but do know that you can replace the final drive on a 1200 with a 1500 final with some rather minor modification. You'd have to use the 1500's rear wheel, caliper bracket (with some grinding) and drill out the mounting holes slightly on the swing arm.

in the case of the 1500 swap. Which drive shaft do you use? I pictures it kind of looks loke the one for the 1500 is longer than the one for the 1200. I can't be sure and I don't want to pull mine right now to find out.and I can't remember from last spring.:stumped:

I'm not 100% positive but I believe the 1500 driveshaft will fit. You can contact the author of the article with the link below and ask him.

You can get the rubber isolators for the 1500's rear wheel because they are replaceable, the earlier wheels had the rubber isolators molded in and are not replaceable. The 1500 has a larger tire with about 80-90lbs more maximum load.



JBZ, from everything I've read the final drive along with the 1500's drive shaft goes into the 1200. I've also heard the 1200 wheel and flange will mate with the 1500 final drive. I think that was mentioned on the GWRRA board some time ago.

the 1200 drive hub flange does mate to the 1500. of course there are 5 and 6 drive lugs depending on the years. As far as drive line length I only measured the actual drive lines that slides into the final drive to the end with the spring. Seeing as how it is a 2 piece you might be correct when they are both put together with the coupling,< second piece>up by the boot. I know the overall swingarm length of a 1500 is a little over 3 inches longer on a 1500. JB.

My rubber isolator is replaceable. :baffled: ('87 GL1200)

Either way it sounds like what eek is proposing is way more than $57worth of work.

This is what i found out. I tried sliding the longer 97 1500 driveshaft up into the 84 engine u joint. It didnt want to go. I gently tapped the back end and still no go. I tried the original 1200 shaft and it was a no go. I had to pull the u joint out of the swingarm to see what was going on. when I tried tapping the 1500 ujoint it burred thestarting splines on the u joint. i swiiss filed it and got the 1200 driveshaft to fit. I tried the 1500 driveshaft a no go. I miced them both and the 1500 was about .040 or 1mm bigger than the 1200. JB

That's good info, all I knew was from a couple of postings from those who had done it before and it appears either there's some differences in the models they were swapping or they left out something.
