Driveshaft saver

I’m working on my new to me 2016 zr-9000. It only has 375 miles. I read up on the driveshaft bearing issue. Should I get the driveshaft saver from barn of parts and install? Gen 1 or 2? Or should I pull the bearing, anneal, green loctite and reinstall? How does one get the bearing off in the future if the driveshaft has been expanded or loctite on? Cut it off?

The best drive shaft saver imo is from precision EFI. Have them on my sled, my dads and my buddies.

That will fit the ‘16 as well? They advertise for the 998?

Barnofparts.com is a shop that makes parts primarily for Yamahas but this now includes the procross. My understanding is they came up with the idea that Precision EFI copied. I'd suggest reaching out to them.

Also yamaheater.com - they make a part that allows this bearing to be greased.
I would buy from Barn of Parts; they came up with the concept and so should get the money. I don't reward plagiarism

I personally feel the precision drive shaft saver is the best regardless if they were the first to make it or not.

I run the newest update of the BOP's saver; nice piece that is easy in/easy-out. When things are susceptible to corrosion I'll take a hex-head that I can heat and remove with a socket every time over an allen-type fastener although I hear he may have changed that since last year.

Short answer, at zero miles.
3000 miles will either need a new shaft or a machined shaft.
If yours has spun, 99% chance it has, no form of wedge will help.
Here's one at around 10,000 miles.


Extreme case, but worth noting.

If you see a lot of rusty dust, around the brake caliper, that's a pretty good indicator the bearing has spun.
New shaft, new bearing, lock down to 40ftlbs, and maybe think about the bearing again at 9-10,000 miles.
Re-grease with Aeroshell 7, which is what Peer uses, every 4-5000 miles is not a bad idea either.

i did one on a 13 with 960 mi this summer . when i pulled caliper, cross marks or knurling was still visible on shaft .so i stuck it in . i would think your golden ! not at 5-6 thou . i was scared every year till dust got crazy then i knew i was going in to find out the issue . even gave her new pistons old ones look like new ring end gap was fine at 6000 mi .

I just ordered one for my 2014 ZR 8000. When I had the track out I noticed the slop in the bearing and my dealer knurled the area the where the bearing sits and that tightened it up. I haven't ridden it yet so hopefully putting the driveshaft saver in will tighten it up more and will be good. If I had known about this device I would have bought a new driveshaft with a saver and been done with this mess. My dealer claimed he had only seen a few loose driveshafts. Yeah and I have a bridge to sell.:LOL:

I have had to replace the shaft on both of mine, I have been thinking of getting one of these, the Precision EFI is A nice looking piece but they say it does not fit the Stroke shafts. I didn't know the inside Diameters were different.

I replaced both shafts, on our 2017 & 2018 ZR6000, fall of 2020.
The Barn of Parts shaft expanded just barely fit the new shafts. Had to use a brake hone to smooth the I.D. just a hair.
Fit was very nice and smooth.
New bearing & shaft got snug at less than 20ftlbs. Final torque to 40ftlbs.
Bad season last year. Only 2100 miles on one and 1200 miles on the other.
Both solid with no dust, wobble, tunnel flex, or brake pulse.
By Stroke shafts, if you mean 4 stroke shafts, they should be the same.
At least my past 2014 XF7000 was.

Precision EFI Siad they don't fit 2 Stroke shafts, I don't have a 4 stroke shaft handy to verify.

The PEFI website is saying it’s specifically made for 998T sleds 9000 series.
