ok, i'm convinced. now if someone could only tell me how to up-rate my CAT without going to an official dealer with the software access? i'm in guelph, ontario, canada but spend 99% of the time trucking in usa. any leads would be appreciated. i know i can do it thru pittsburg power but their prices aren't cheap. and i don't need 600 hp. all i want is to get my 475 hp 1650 lb/ft engine perform as 475 hp 1850 lb/ft engine.
My 600 kitty purred at 600 then I put the Pittsburg variable on it. Now it growls and I am scared of it![]()
Don't keep real acurate MPG figures as for what I do but know that running empty (78,400 lbs) on the 3 setting I figure, just from where I need to refuel, I gained 3/4 to 7/8 MPG. Love it when I turn it to 5. And that's running it against a Spicer 5x4 air shifter that was supposed to be for a garbage truck. Dealership said it wouldn't work and would maybe last a month, that was a year ago.![]()
Only thing we did was put a HD Soft Touch clutch in it.
Figure it paid for it's self in about 9 months.

The Alaska building method. Measure with a micrometer. Level with a laser. Cut with an axe.
"Official dealers" like Toromont CAT here in Canada refuse the increase the torque without me modifying the transmission and clutch. The tranny is 16913 and the clutch has a rating of 1700 lb/ft, I think. BTB, solo, when you increased your torque, did you do anything to the clutch? One guy on another forum said the tranny can take the extra 200 lbs of torque, but the clutch might kick the bucket. Any comments?
Didn't do nothing. Just an engine. I've done it at the CAT, and they could care less, what's my tranny or clutch ratings. I've called Eaton, and they said NO!
But than I've called the Volvo dealer, their service manager, has been in this business for many years, and spend 17 years in a pit. He said 9 out of 10, it's not gonna be a problem, and the way you drive, i could almost guarantee it.
Pessimist,- is just well informed optimist!
I found a private guy near Toronto, ON who used to work for CAT and now has all the sofware for ECM tuning. Still waiting for him to reply to my email. If that doesn't work, will try to do rerate in the US. Toromont INC in Canada is the official (and only) CAT dealer and they don't want to take chances of getting sued.
About the clutch: thanks for the info. I talked to a couple of mechanics in our company shop and they said not to worry. "Change the clutch if and when it goes," was what one guy said. I found a dealer for the famous LIPE clutches which are more durable and cost less than what truck dealers sell. One with 2000 lb rating goes for 800 bucks! Will put it in when the time comes. Thanks again for the info.
Here's what I almost spent in Cnd dollars (US$100=Cnd$120)
$900 - 2000 lbs LIPE heavy-duty clutch
700 - shop labour (take out/put in)
2200 - tranny rebuild (from RTLO-16913 into RTLO-18913)
TOTAL: $3,800 or US$3,166
It really would have been a huge waste of money for the meager 200 lbs of torque increase. Thanks to everybody for comments and input.
