broken driveshaft

This is not a rant, it is a question to see who has broken a drive shaft, what track length and build date.

we were out today and a buddy broke his drive shaft in a not so good spot- we were not towing out!! His was a 146 x early build-pre October.

We doubled down to the trailer tore mine down and rode back to his and re and re in the field, then rode his out.

Mine is a Nov buld 146.

Curious if all drive sahfts are at risk or did BRP recognize the problem and fix for late builds.
 
IMO---When Doo went to a tube for a driveshaft--it was a mistake. Yes--If you do a search--you will see that many driveshafts have been broken already this season on the XP.:face-icon-small-con

When was the last time you heard of a Doo driveshaft breaking--they have been so heavy duty--it was something you did not have to worry about---but now when you hit something in that area of your track--you better worry. They Dragons have the same design--Not impressed by either one of them:mad:.

I did a prememptive strike on the driveshaft for my TNT I am longtracking and drilled six 1/4" holes through on the gear side and four on the brake disc side and TIG welded shut. IF a small diameter solid steel shaft is so much stronger why doesn't your truck have one??????

The doo accountants struck again and cheaped out by not welding the splined ends into the large diameter hollow tube that holds the drivers, they just pressed them in.

A large hollow steel tube is stronger and far stiffer because it has four surfaces to resist bending where a solid has only two. The larger the diameter of the tube the stiffer it gets and stronger, just crawl under your truck and look at the drive shaft.

Good Luck

Cost of steel and rotating mass--Maybe;)

I had not looked that close at that --good call LRD--It that is all it takes--BRP will probabley have the dealers welding them up when they break--but not before as a precaution agianst claims--LOL

This of course means that it is built right---which you have found was not--What were they thinking on a press fit??
And it is not like I have not twisted a couple of shafts out of my truck over the years---the tube keeps being made out of thicker material each time--LOL
