I have intentionally left the photos large, to try to clarify any detail I did not explain in the text. This modification DOES require the use of a lathe, I have tried to write it so as to allow you to go to your local machine shop, brother in law, mate or anyone with a lathe…and it will be done correctly Much thanks to John O’Rielly (PLAGER 7) in Brisbane for passing on the information and problems he had with this modification. Fig.1Standard Drive Assemblies T50 left and AE101 right T50 Speedo Drive Adaption Rev 1 Feb 2003 2 Step One:- Dissassembly T50 Drive:- Disassembly is simple, remove the “C” clip from the drive housing , just above the drive gear. This will allow the shaft/gear assembly to be withdrawn from the housing. Remove the “O” ring from the housing. Wash all parts internally and externally to remove oil, grease and road grime. Fig.2 T50 Drive Disassembled T50 Speedo Drive Adaption Rev 1 Feb 2003 3 AE101 Drive:- Disassembly is similar to T50, remove the “C” clip from the drive housing , just above the drive gear. This will allow the shaft/gear assembly to be withdrawn from the housing. Remove the “O” rings from the housing. Remove the three (3) philips head screws from the cover on the top of the drive housing. Carefully remove cover, be aware that the small parts in side may be stuck to the cover. Remove all internal parts, record order of assembly. Wash housing and shaft to remove oil, grease and road grime. Fig.3 AE101 Drive Disassembled T50 Speedo Drive Adaption Rev 1 Feb 2003 4 Step Two:- Shortening the Drive Shaft Drive Shaft:- The T50 drive shaft needs to be shortened to a similar length to the AE101. I reassembled the AE101 shaft and housing, and then measured from the top face of the AE101 housing down to the top of the AE101 drive shaft. ( Fig.4) Record this reference depth, (I got 17mm) . Fig.4 Drive Shaft Depth Std AE101 Shaft & Housing The T50 drive shaft will need to be shortened to give the same depth as measured in Fig.4. When I did mine, (and a few others), I found I needed the T50 shaft to be 68.0mm long. Fig.5 Fig.6 The drive shaft is hardened, so I used a belt linisher to shorten the shaft, it could as easily be done on a fine grinding wheel. Remember slowly does it, regular checks of depth in housing and do not let the shaft get too hot during grinding/linishing, this will affect the heat treatment and consequently affect the strength of the drive dogs on the shaft end. Carefully deburr and chamfer, end detail should be similar to original AE101
