Yup and now I can do 80mph between jobs. Oh yeah still spent too much on the R model lately.

Well, tranny is in, all plumbed and was ready to go. Batteries got connected. truck cranked but wouldn't start. yeah fml. ECM internal keep alive battery bit the dust about 2 years ago. CAT software couldn't communicate with it since but the truck ran fine just had a check engine light flashing. I guess whatever parameters and info it had left disappeared with the batteries disconnected for a week or so. Took the ecm to KW dealer which luckily is about a mile from where the truck was, they bench tested it and yup, dead as a doornail. Off to the truck junkyard I went for a new to me ecm, back to the dealer to have it bench programmed. Of course the programming for my truck is no longer available seeing as it's old enough to drink. They installed a program that was generic 3126 software set at 250 hp. Well. the truck started but would only run for 20 seconds and shut down and accelerator did not work. Back to KW, Now that it was in the truck they could send a guy over with a laptop and set everything up correctly. a couple of hours tapping the keyboard, calling Kenworth and Cat and the CIA for secret codes, and equations, he waved his wand, I made the sign of the cross and viola, the truck runs the crane runs and I'm broke. I guess there was no way around a new ecm anyway because the speed limiter in the computer needed to be reset for the new .80 overdrive in the 9 speed and the old ecm wouldn't talk to anybody anyway. Once I get done paying for this little debacle at least I know a whole lot more about roadranger gear ratio etc. and cat ecms. Oh and no more check engine light so that's something good I guess.

R-model cab resto report
66dc75 replied to Vladislav's topic in Exterior, Cab, Accessories and Detailing
looking good Vlad -
I just feel better now that the next time I need to stack up some trucks and chase a wolf through the fjords at night Volvo has me covered.

It started out as a gas job, gas motor B models didn't have tachs. At least I haven't seen one with a tach.

Yeah I'm real bright, I'm 6'6" and I built the pickup with a concave cab and then bought a short cab R. I can stretch out in the Autocar though. -

Trial fitting of seats maybe I should have gone for a plus 4 cab. Good thing I was too cheap to buy the armrests option -
Yup just dropped the drive shaft and bell housing off at the machine shop. We need to use the small bellhousing but it's an early steel one that doesn't have the big enough reliefs for the later counter shaft bearings cut into it. I would rather use the the steel one than the aluminum anyway. Have to go pick up the new 8 bolt straight cut gear pto today as the 6 speed used a six bolt with spiral cut gears. Why can't they all use the same accessories ? PITA I think I'm running out of stuff to buy ar modify for this thank God. I'll build a rear support after its all done or see if I can find something in a junkyard. The twin countershafts wil eat some power to turn but I'm confident that it will be a much better setup.
-
I'm hoping for the same results, The 9 and the 8 are pretty much the same except for the LL. I'm just sick of winding it out to 2400rpm and then having it fall flat on the upshift. It'll also be nice to be able to go a little faster than 64mph
-
Actually plans changed and I'll be using a RTX12609 so the noise and old age of the trans won't be a problem. It's getting a rear mount as soon as possible, we were talking about that yesterday.
-
Jim, not even sure it could do that right
-
Best laid plans......... The 13 speed needed a few things that are getting hard to come by now that is an antique, I had 3 roadrangers given to me, one was a rtx12609 which looks to be a much better choice for this and will give me the overdrive I want so it's going in. Just need to get a new PTO though and a new driveshaft yoke. It was time to do the clutch anyway and the six speed sucked to live with, anybody want to buy it?😀

Basic seats inc midbacks. Cheapest priced ones but they are comfortable -

Thanks Tim, I did it for noise but it might help block some heat, The vinyl that's going on the firewall has some foam bonded to it so that should help too, -

Steering column out for painting and the new wheel. New seats came in, roll of embossed vinyl for the firewall door panels and can back came in. I've had a couple of truck speaker boxes under a bench for at least 15 years finally will have home for them. I plan on connectiing them together spaced apart to install a stereo and cb in between and use as a center console between the seats. Anybody know how to get the headliner down without cracking it? I'd like to dynamat the roof and change the air horn but it doesn't want to pop out. I really don't want to break it. Also found a dash panel on Craigslist that had a mack speedo and tach, my existing speedo doesn't have a bulldog and the tach is for a later truck. Dash came with a bulldog hood ornament and a really nice DM800 nameplate for 50 bucks, -

I think you dodged a big bullet there Paul. Sounds like you would have had an empty wallet and an empty garage

Hi Bob The consensus is it will work, 1 3/4" input shaft and small bellhousing., My first crane truck had a 210hp DT that had a rt910 behind it, worked great. I've got the old timer truck mechanic doing this for me that converted my Louisville 3208 cat from an allison to a 910 and that worked out good too although obviously didn't gain any top end speed.. This one should get me rolling a little faster.

Whoever came up with that Fuller 6 speed should be brought around back and beaten severely

The rto was free Just needs a couple things replaced
