According to a post by Mr.1200 it's an easy swap:
All the 1200's camewith the sameFinal Drive unit...Even the 1500's have the same Gear Ratio,only the 1500's have beefier bearings,and will fit in a 1200,by drilling out the four drive mounting holes in the 1200 swing arm..
Since the dust shield bolt doesn't have much stress on it seem like you could replace it with a oval or flat head machine screw, just counter sink the hole in the plastic a little bit. That way you'd have maximum clearance.
Thanks Mr 1200 when you mention the inner spline do you mean the driven flange? Excuse me for being dumb but what does feel free to PM me mean.One final question will my 1200 drive shaft work in the1500 final drive? Thanks
Lots of pics and detail, but, you need to use the 1500 rear wheel which is commonly available on Ebay from trike conversion takeoffs. There are several advantages to doing it this way and on a Wing with bags you'd hardly notice the difference between the 1200 and 1500 rear wheel.
Excellent info lads. Hey Mr1200, I seeyou've become a Guru, when did that happen? I'm surprised Redwing hasn't been looking for an enquiry into this (althoughhe's hardly worth a guru tag). He probably didn'tfind his glasses yet and might not know you're a guru now.
You need to mill down the brake caliper mount. You will use the drive shaft from the 1200, but you need to order a new seal where the drive shaft goes into the differential. You will also need to get a smaller tire. The one for a 1500 is too tall and too wide. I did use all the 1500 spacers and axle. Everything else is the same.
