Rob Posted October 5, 2010 Share Posted October 5, 2010 Tonight I sacrificed a cab for the good of three others. I purchased this badly rusted cab someone had patched/repaired with a new roof skin and rear drip rail, (gutter). It appears the truck was then run for awhile, and clipped in the cowl with an end loader bucket, destroying it. With both my 74RL797L, and my 77 R795 needing sheet metal work in the roof and rear gutter areas, I used a five inch, 3/32 cutoff wheel and took the roof off the cab just under the drip rail. Pretty clean job that way. Tomorrow I'll strip out the inner sheet metal that is not needed by drilling spotwelds and get this skin installed onto the 74 truck. The gutter will be installed onto the 77 truck although I have new parts. This 74 truck is not a long way along so it can go back in a corner till spring under cover. I'm wanting to concentrate on "Project R-12" this winter, and need the room this truck, and the associated parts are taking up.The relatively new windshields, with gasket were removed and will be installed into the new R612 as both are cracked. The PP1 valve now also resides in the R612, and this solved the air leak problem within the dash. Also the dash panel was appropriated to replace the missing original.

other dog Posted October 6, 2010 Share Posted October 6, 2010 That's way better than what the ancient Inca's used to do. They would carry perfectly good R-model cabs to the top of an active volcano and throw them in for a sacrifice. Quote Producer of poorly photo-chopped pictures since 1999.

Yes, but then they come to the realization of how much GOLD could be traded for just one of those cabs and switched to another brand for the sacrifice. Can you guess which red oval truck is in high demand for this operation now? Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Rob Posted October 9, 2010 Author Share Posted October 9, 2010 Well tonight I removed the factory underdash HVAC unit after putting power to it. The fan runs on all speeds and will probably be installed into the 74 RL complete. This truck had a "Kysor" roof mount unit that was no good and missing parts. The 866 engine however still has the junk compressor mounted, (Sanden from the looks of it) installed so 1/2 the battle is over from the start. I'm not going back to a roof air unit but rather will install a front mount condensor coil and quite possibly use this underdash unit. I did discover the cab is either a 1989, or 1990 model as most of the plastic air lines are date coded 1989. Too bad this cab sat exposed without doors for some time as it had the upgraded interior package that was destroyed partially from exposure.

Rob Posted December 22, 2010 Author Share Posted December 22, 2010 Yesterday I finished up welding in the new/donor drip rail across the rear along with numerous patches above the windshields, and along the cab upper rear structure. These pieces/parts are various parts from the donor cab. I still have the roof skin to weld down, and may do that yet this afternoon. I still have a lot to do so this may be stalled a bit further. It can now however go outside if need be under a canvas tarp. Delivered the front fenders, grille shell, brake drums, backing plates, bumper, bumper filler and hooks, breastplate, battery boxes, and a lot of small parts to the blaster yesterday for the B67. These will all be "Mack Red" (as per Herb's influence). I will send the tires/rims over soon as they will be repainted white. As soon as I get this chassis rolling again it will move to the further dissassembly stage for engine/trans/cab removal and further stripdown/rebuilding. I really like this truck and have decided to retain it. If you remember this is the truck that tried to saw my left thumb off 12/12/09 and I've still not had feeling return in it. Several months ago I purchased an NOS pair of stamped steel rocker covers for my 12V-71T and I also got those boxed up to ship to the plater. I shoved that engine into my car wash bay after picking it up at B61 Freds house, buried it behind palletized truck tires, and have forgotten about it for nearly a year. I also relocated three generator sets from my building to a friends barn for the winter. This will grant some much needed room for truck work.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Needless to say, it doesn't work any longer. It takes a conscience decision to take photos as I've done this type of work for so many years, it's basically routine in nature. I'll grab some photos as progress moves forward. With no customers' cars scheduled through the first of the year, I may be able to get a little done.......Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
