the instruction guide they send is for the forward control cabs and school buses good thing I had the shop manual.
so the parts all match up but there is no sector shaft packing retainer to hold that rubber packing on the sector shaft in place. In the diagrams it shows the retainer; is it needed???
Classic parts tech support says no. I hope someone can shed some light for me and "steer" me in the right direction. I'm at a loss.

The diagram in the shop manual shows the retainer I asked about. However as I didnt think it was in 1950 and they used packing. The new one is a rubber gasket that is pressed down onto the bushing so no retainer is needed. Boyd also told me to use #2 permatex on all threads of bolts that come in contact with the gear oil inside the box. I feel better now. | | | | | Joined: Apr 2005 Posts: 7,440 Bolter | | Bolter Joined: Apr 2005 Posts: 7,440 | Thanks for keeping us informed.ðŸ›

Most use John Deere corn head grease for lubricant. It is a 00 grade, self leveling grease, little thicker and not as likely to come out like gear oil. With new seal and tight bushings, the oil will work, just be sure the sector shaft is not worn. | | | | | Joined: Nov 2005 Posts: 123 Shop Shark | | Shop Shark Joined: Nov 2005 Posts: 123 | when I spoke with the guy that rebuilds these for classic parts he told me to use Permatex #2 on all threads that screw into the box itself and come in contact with the oil inside. He also said he just uses a 90 weight oil when refilling. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | "He also said he just uses a 90 weight oil when refilling."
Too bad he does not do a professional job. | | | | | Joined: Feb 2000 Posts: 5,201 'Bolter | | 'Bolter Joined: Feb 2000 Posts: 5,201 | Again, as long as the sector shaft is not worn, the bushings are tight, and the seal is tight, gear oil will work. 00 grade grease is equal to the old steering box grease GM used, it's much thicker then gear oil. A good compromise is 50/50 axle grease/gear oil. Just remember, there is no seal at the top of the gear box where the shaft enters, so don't tip the box over if you fill it before installing. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | Corn Head gear grease is 0. A little thinner than 00, but I think it is still self-levelling and still a grease. Farm supply stores have different brands (John Deere seems to be commonly available). Sources of 00 grease. | | |
