All the 7500-9500 H/J trucks became 'Brigadier' in 1978. The steel 'butterfly' hood was an option through 1980 on 9500's with 6-71 engines. All the 7500/8500's could be ordered with either hood. There were other differences between a 1977 H/J and a 1978 Brigadier/Bruin than just the hood. |
Re: 1966-81 Chevy H/J Series
I also found out that the only engines available for the short-hood (93" BBC) H/J 90 series in 1970 were the Detroit Diesel 6-71 and the Cummins NH 230.
In 1971, a tilting hood was made available for the short-nose models, and thus the Detroit Diesel 8V71 and the Cummins NHC 250, previously only available for the long-nose (C/M 90 series) models, were also available for the short-nose models. Additionally, the Cummins-powered models were given two designations: the HN/CN (4x2) and JN/MN (6x4) models were given NH-230 engines; while the HC/CC (4x2) and JC/MC (6x4) models had the "Custom Torque" NHC-250 models. ~Ben |
Re: 1966-81 Chevy H/J Series
Ben,
You are locating some interesting info. Are they from GM Manuals ? |
Re: 1966-81 Chevy H/J Series
While we are all talking about confusion, lol, let's talk about the 12V-71 in a 9500 Long Nose !!
Most say that they weren't available, although we had heard from a couple of guys who actually owned some. Recently it was proved to be true to a higher degree. Maybe Dan can jump in with some more info on it. Bob, what would be your experience with this application? Bill |

Re: 1966-81 Chevy H/J Series
I've always been interested in the cabs on these trucks. Really weird looking design, looks like a cross between a 67-72 and 73-87 C-series. Anyone got any information or history on the cabs used on these trucks?

Re: 1966-81 Chevy H/J Series
Special-k, since you posted the video I will ask you, but anyone else feel free to answer if you know. In the shifting video, the interior view one, I see the Range and splitter air lines and switches ( well cant see the range switch but can see the line) but what are the other two lines and switches? I would assume if it was single it would be either an axle range ( 2 speed) or a Diff lock though I am not sure you want to run 2 speeds on a twin screw, though I guess i could still see diff locks working. Anyway any idea what they are?

Re: 1966-81 Chevy H/J Series
Were all of the dash panels covered in cheesy wood grain shelf paper? or was that optional ?

Re: 1966-81 Chevy H/J Series
Neat info. I seen a brochure from '66 which showed these trucks somewhere. They just always looked like a very modern design for a cab that went into production for the '66 model year. And I always wondered if they had some kind of roots in the pickup division, being a early design/prototype or something.

Re: 1966-81 Chevy H/J Series

Re: 1966-81 Chevy H/J Series
WUF------As a little bit of history, we not only had tandem 2 speeds, but with Eaton axles , we had tandem 3 speeds. The 3 speed concept was an effort to compete with Roadranger transmissions, and was achieved by running 1 axle in low range, the other in high range and the ratio was equalized through the interaxle diff[ or power divider]. This concept came out in the early '60s, and worked OK except for occasional broken levers in the torsion spring assembly in the shift motor area. You had to be in low axle range in order to utilize the power divider to lock the axles together in slippery conditions. Keep in mind, on slippery conditions , unless the interaxle lock is activated, one out of 4 wheels can spin and the truck won't move. When you engage the differential lock , at least you have 1 wheel on each axle will spin . Nowdays many users will buy full locking diffs, where all 4 wheels are locked and will spin . The fleet I was in in the '60s had about 50 Fords and 50 Whites with tandem 3 speed axles. In '72, I worked for a Cleveland area grocery chain that had about 60 JI 9500 GMCs with the 6-71 and tandem 3 speed axles . I still remember a hotshot mechanic grabbing gears in the parking lot. It was a fast setup !

no one has answered about the wood grain contact paper for the dash yet though..... |
Re: 1966-81 Chevy H/J Series
Wood grain contact paper ? That was from a housewife trying to spiff up her guys truck ! But now I vaguely remember, but don't recall what vintage . Towards the end, Brig dashes were basic grey .

Re: 1966-81 Chevy H/J Series
Our brand new '71 9500 also had a Wood Grain dash.
Can't really remember if my '67 7500 had one, I'll have to look at some pictures. I always liked how it looked. |
Re: 1966-81 Chevy H/J Series
I only say that as I have always kind of been an "anti" artificial wood person never cared for the plastic " Country squire " wagons either..... and now the reality of dealing with a 30+ year old truck is that the decal has weathered pretty poorly and the thin materiel has faded and peeled, just reminds me of "shelf paper" is all. I was wondering if it was an EVERY model thing or if it was part of the drivers convenience package or something...or if the commercial trucks even offered " trim levels" ( SL xl sierra chyenne what have you )

Re: 1966-81 Chevy H/J Series
Just as a little more info.... the Yellow truck I just posted has a V arrangement diesel
( assuming 6v-53 because I could see exhaust through the wheel wells on both side... I suppose it could have been a toro flow ) but don't know the trans I talked to the yard owner but it was not his truck... out of respect I did not climb up and look in the cab.... the green one there was no one at the business, so it is a stay in the car picture... I know even less about that one. |
Re: 1966-81 Chevy H/J Series
The Green truck looks like a newer model going by the "Hockey Puck" Cab Lights.

Re: 1966-81 Chevy H/J Series
tell me that does not remind you of shelf paper
