This is exactly the problem I'm having with my cart. The splines on the input shaft and motor drive coupling both stripped. Unfortunately, the problem extended into the motor as well. Motor shaft wobbles and also make grinding noises (I believe motor should spin smoothly, quietly and with little effort). At least I now know the input shaft is a piece of cake to replace and found the part on Amazon. Afraid I'm gonna have to replace the motor though and that looks like $800 give or take. My thinking is the metal filings from the splines got into the motor and did further damage. I will take the motor up to the shop and see what their tech has to say about it. Maybe it can be rebuilt; don't know. I'll do some further research online first. Any comments or advise appreciated. Thanks a ton for the vid.
Question you mentioned there was a o ring when pulling the input shaft out. I didn’t see you put on back on, just a c-clip. Do you know what size o-ring it was and does it go in front of bearing between that and the c-clip?
Hi, this is what I was looking for. I do not suppose you have a link to parts to replace these with? The c-clamp is shot, and I assume a new set of bearings might be nice, but I am not finding a breakdown diagram of part numbers anywhere. Thank you for the video!
@@jimcampbell1705 I have RZR 800 i converted to Hayabusa engine (for golf cart parade in my town) but I retained the differential of Polaris RZR800. The original is CVT - I took the cvt clutch out and trying to convert to sprocket to sprocket. The Polaris RZR diff input shaft is 19 splines and 7/8 or 21mm splined diameter
@@zzzzzsleeping of course I only had an old input shaft on hand. 7/8” = 22.23 mm so this one being worn, I would venture to say it’s close to 7/8” I would order one off of Amazon and measure it. If it’s not what you’re wanting, you can always return it.
