I just finished my 1973 Rupp Nitro 295 I hope to post pictures soon. I was wondering has anyone installed a newer rear Track or suspension on this model. I have a track that is okay but not ideal,I want to ride this sled this winter I have 2 other sleds to ride but I think pulling up with this 73 Nitro will surprise and excite anyone who sees it. Thanks for any response Gary
wow that is what i want to do with mine the suspension looks great can you share the spec: what type of sled the suspension came out of etc. what had to be changed front drives,what type of mod.Thanks for any help.
This is a simple swap. I use Polaris suspensions, only because i'm more familiar with them. Any track/suspension will work as long as tread on track is 3/4" or less. Mark center of axle between drivers then have machine shop turn off the Rupp driver hubs. Get a pair of 8 tooth drivers(I use John Deere because they go on a round shaft and pin just like the newer Rupp drivers) have center drilled out to fit the Rupp axle. Slide drivers on axle and lay in track so drivers are where they belong. Make sure mark on axle is centered between drivers then mark holes for pins. Drill holes then pin drivers. Your done. Reinstall everything. If your not sure where to bolt suspension at just find a sled like the suspension came out of and measure from center of axle to center of suspension holes. Then from top of tunnel to center of holes. Transfer measurements to Rupp tunnel-drill new holes if necessary and bolt it in. Make sure to use a steel mounting plate, make one if you have to or the holes will egg out. Sometimes you get lucky like I did with my 73 Nitro. The suspension fit right into the same holes as the Rupp suspension. Once you do this you won't ever want to ride one with the old suspension in it. Don't believe me just ask Rooney!!

red19lite: okay, the two piece comet pullers work the best in my experience. have someone check the runout in that crank when you have it out no more than .004 better close to zero if you been banging around on it getting the clutch off
