Barn of Parts Driveshaft Saver....Bearing Lock

[Bigblue1]

Just went through and re-greased bearing etc. BOP saver flat out does the trick. The shaft is as good as it has ever been. When not the BOP saver is not in, my bearing slides in and out easily so I guess I did it just in time last year.

I guess when I did mine and come up with 65 ft lbs wasn’t wrong afterwards. New shaft and bearing .001” different when did all measurements. When I pull out we will see what end result is.

thanks Pan

I thought Travis said the bolt is only good for 43ftlbs

Bolts are 1/2" grade 8 and fine thread so should easily be good for 90 ft lbs according to my chart.

The wedge threads are not hardened so they will likely strip before the bolt fails.

Could you harden them or make them out of tool steel? That would help with higher torque values and save the jaws from deforming.

They can easily hold 90 ft lbs

If I make the jaws out of a hardened material then I feel like the tool will have more resistance itself to overcome. I have some harder wedges to experiment with when I get time.

Ok, it was just a thought.

I'm thinking a hardened steel saver might invite more problems. Guys will be torqueing it to 150 ft. lbs. on a shaft that's worn 10 thousandths to get a snug fit. This will cause the shaft to split and that will get ugly.

You will never split that shaft that easy...you would snap the head off the bolt first.

I'm glad you said something! Lol.
Didn't want to be the first!

Right and if they can split that shaft, I would pay to see it done. lol

This shaft is nothing special, if it was it wouldn't be that easy to wear out so fast. Never say never!

I had my sled in and asked them to check it but it would cost me way to much if there was not a problem

Easy to check. Lift rear of sled off ground, loosen up the track. Crawl under sled and grab driveshaft next to bearing from inside the tunnel and push up and down on it.
If its worn from spinning on shaft you will feel the play between the bearing and shaft.

If cat would just tighten the tolerance expectations from the outsourced manufacturer the dam issue would be non existent!!!
I replaced a driveshaft on customer's sled a month ago and the fit had a slight interference!
I was hopeful that the shaft was actually updated and improved but I been through a couple more new shafts since and the fit is all over the map.

I remember when you installed it you actually pulled the shaft out of your sled and tested it on a bench at different torque values!! So I'd say you torque it properly.
