Readying for the KW

The sad thing about parts warranty is that most often they only cover the defective part(s) and not the labour. It would be nice if they would reimburse you for some labour cost due to the defective pump being beyond your control. If a shop had done the repair, they would have had to eat the labour cost until they submitted the warranty claim with the supplier.

 

[John C.]

Most warranties now have limiting conditions such as "incidental costs such as labor, lost production, down time, freight and so on." There is also many times a specific clause that the warranty will not pay out anymore than the cost of the failed part. Independent shops usually try to market themselves as being more fair and less costly that a franchised dealer. In fact many will just stop a repair until some kind of guarantee of payment is made.

It has always been the policy of franchised dealers to charge the customer and try to make them pay repair costs up front. The customers then get to wait for their money until the factory pays the warranty claim. In my experience that can take up to six months for a situation to be resolved. A parts warranty is pretty easy in that you give them the defective part and they give you another part in exchange.

Easy, as long as the part that they give you in exchange was not rebuilt or assembled by the same person as the first defective part!

 

[John C.]

Actually, the problem would have been if the engine had burned up from lack of oil. How would the Cat dealer have covered that?

 

[DMiller]

Was explained wouldn't have, they go to court for such events.

 

[John C.]

That has been my experience as well.

I can't hit the like button because although i agree with it, i don't like it

 

[Truck Shop]

But when over hauled by cat and a OPT warranty bought with overhaul cat covers things
like the original crank that was in that block.

 

[56wrench]

Thats true but also thats one of the reasons their in-frame or total overhaul costs more. Also, they like to replace a lot of other stuff to be able to guarantee their repair. Most of the big brands do the same in my experience. I may not agree with them but i understand their point of view

 

[Truck Shop]

Well I know one cat customer that was glad he bought a OPT-two months after it broke
the crank on the 3406E.

We have a C-16 in a log truck that they rebuilt, cost 43,000 bucks but they have torn it down twice to replace pistons that seized plus a few other things on their dime. They don't know what caused the failures but stood behind everything.

 

[Bluox]

Did you replace the piston cooler nozzles ?
Bob

 

[JPV]

I would assume they did, the first time it seized the #6 piston and #5 was on the way out with about 70,000 miles I believe. The only thing they found was one of the cooler nozzles wasn't aimed correctly but wasn't off too far. They changed just those two Pistons and liners. The second time about 6 months later it was #4 piston and everything else looked fine. They replaced all 6 injectors that were remans installed with the original overhaul, the thought was that they could be over fueling and had been part of a bad batch of injectors. I never did hear if they tested them or what came from that. That was 6 months ago or so, it's been fine since.

 

[Truck Shop]

Piston coolers are aimed on injection test stand with a bulls eye target.

 

[JPV]

I see, I knew they have to be aimed correctly but didn't know how they did it.

 

[Truck Shop]

Plus few cat shops have the equipment to do it, with time involved may as well install new.

 

[Bluox]

The step in the disassembly book right after remove oil pump is remove piston coolers most people miss that part.
They don't go back in till the rods are back in.
It's a sure bet if the pistons are removed and put back in with the nozzles still in they will be bent.
And if the motor was dirty they may be plugged.
So the safe bet is to replace them.

And how many have been broken through the years on a 855, and wonder why low psi.

 

[DMiller]

Coolers are still in place and in good order
Pressure check showed were all spraying and evenly

I remember when Cummins went from the Steel nozzles to the Nylon, what a joke, first two years out we replaced them by the buckets due to cracks, leaks, finding tips during oil changes.
