Low voltage relay to fuel pump, and my TO bearing is done causing some damage to plate. $1375 today for repair, be ready after 4pm I've been screwed.

 

Did you change you diff gears when you went to the big tires?

 

I regularly tow loads of 20-24K on my GN and BP trailers, and I have 35" tires, 373 ls diffs. I have had no issues relative to the gear ratio not being what some consider a little too high. Even those with the 410 gearing have had throwout bearing problems and torn up clutch discs.

Just sounds like the throwout bearing is/was done, maybe the clutch disc was also close to being done, and this load was the final straw in breaking the Cummins back. Relays go bad all the time too. Wear is wear, goes with the 'using' part of the territory.

I would have been installing a new HD clutch at this point in time, the stock clutch is OK, but if it's crappin' out with your use level at the kind of mileage you have now, the next one will be done in about the same time as this one.

Gears are stock 3.73's. Yeah, better clutch should been what I should of done but he couldn't get one in until Tuesday or wednesday of next week. I was going to give Valair clutch a call since they are pretty local but I really wanted a SB. However for this being an oem it's awfully hard to disengage.

 

yup, was going with throw out bearing and spring failure/clutch plate seperation but see that you have it all settled. these new materials now.....tsk tsk

 

I hope you had the flywheel replaced along with the rest of the clutch? If not, you're gonna have issues with it right away......

 

I broke my DM flywheel at 148,000 mile replace with SM flywheel and clutch pack rated for 475 hp from south Bend Clutchs and never looked back.

 

Now iam kicking myself, should of just waited I'm sliping it out of third and fourth.
