Now that the weather is fine, it's time to work on a couple of tractor projects. I just disassembled and cleaned up the rear axle for the Gard'n Mast'r. Everything is in great shape except for one outer axle bearing and race. I'll be replacing both outer axle bearings and races, gaskets, seals, and the oil soaked brake shoes are getting relined.
The steering box just needs a new sector shaft seal and cover gasket. I will be replacing the steering column tube since mine is really bent, and the tubes are available on ebay for pretty cheap. I just have to order a tube for a Willys MB and cut it a little shorter to make it work. It shouldn't take too long to get this tractor back in shape.

This is the place that I got the gasket and seal kit for the rear end. Their service was great and I got the parts pretty fast. The seals were leaking badly due to the rear end being over full of gear oil. When these rears were narrowed for use in these tractors, they were flipped upside down so that the tires would turn in the right direction. This put the oil fill plug too high on the housing and most people over filled them. Oil poured out of the axle tube when I pulled the axle.

I was told that these rears came from DeSotos from the 30's, so I ordered the seal kit for '36-'42 Chrysler, Dodge, Plymouth, and DeSoto rear axles. I checked to see if the seals that I ordered fit, and they do. The transmission in the Gard'n Mast'r Jr. Was designed in 1933 and used in DeSotos. These transmissions came out in '33 with helical gears, so they are not noisy like earlier straight cut gear transmissions.

I heard or read that the diff and trans were from a '36 Chrysler. I'll bet the parts where exactly the same though. Interesting about the diff being upside down. I'll have to check my JB and see if it's overfilled. I'll be watching your rebuild with much interest.

On another subject I found some good front tires with the original tread pattern used by G'Master. A friend had them on a spray cart he built and I was able to swap him for a coupe of new harbour freight wheels.

Yup, from the research I've been doing and the parts hunting excursion I've been dealing with, has pointed me in the direction of mid 30's Chrysler/ Dodge/ Mopar/ etc. trans and rear. All of the bearings, seals, and gaskets I've ordered fit. I picked up a 1937 Plymouth transmission since I need the tin top cover, the parking brake hub, and the parking brake flange. I got the transmission for 75.00 plus shipping and it will be worth having around for spares.
My rear tires are shot and are size 7-16, and the front tires are shot also. My front tires are 5.30x4.50-6 and the original Gard'n Mast'r Jr. brochure calls for 3x12 front tires. My Gard'n Mast'r is a 1956 or 57 J S model with a Briggs 23 R6d engine. I'm wondering if the 5.30x4.50-6 tire size is original for my tractor. I am familiar with the original type front tires with the wavy tread pattern, and it's great that you were able to find a pair. Are they size 4.10x3.50-6? I will continue documenting my complete rebuild of this tractor here. It will take time since it's a complete restoration.

FYI, the Mopar rear used in Panzers is very similar to these earlier ones and they're also mounted upside down.

I finally had a chance to look a Panzer tractor over recently. My Uncle picked one up at an auction. I've been doing a lot of research on the 30's Mopar transmissions and rear ends since picking up the Gard'n Mast'r. There is some info out there, but not a whole lot, especially info relating to the Gard'n Mast'r tractors specifically. It's turned this restoration into a learn as you go project. I'll probably have as much time researching and parts hunting in this project as I will have in restoring it.

Here are a couple of pics I came across. One is of a 1936 Dodge engine and transmission, and the other is of the transmission I bought from a 1937 Plymouth.

Classic,

Here's what I had on my JB which I think are original. It was confirmed by another GM collector. It's a General Jumbo Jr., 4x4.50-6

I decided to go with this for seating on my JB.

Yup, the Jumbo jr. tires were used on the G Master Jr. I had a chance to buy a pair before I picked up the tractor and I passed on them. I didn't think I would come across one of the tractors. Here is a pic of one being built at the factory.

I came across Buckeye manufacturing while researching an oddball Lambert garden tractor recently. Lambert made automobiles through Buckeye manufacturing way back. One of the garden tractors models was Buckeye. It's interesting how some of this stuff ties together once you research it. I have a thread going over in the Lambert section here regarding my tractor. I just got a new set of points and a condenser, and the points plunger should be here tomorrow for the Lambert. I measured the bore and it's well within std. specs, so I'm honing it out and installing a new piston, rings, and rod. I didn't plan on rebuilding this engine, but the points plunger was stuck in the crankcase cover. I removed the cover, so I figured I might as well freshen the engine up before starting it.

I finally found a pair of original front tires. The rims look the same as mine, but the hub looks larger, and there are 1"ID bushings pressed into the hubs. Thanks to a member here, I was able to get the decals, and I also ordered a couple of the repro engine data plates.

Those General tires are hard to come by around here although I think lots of people used them on different equipment. It looks like you used wrinkle finish paint on your engine tin or is that something else behind the engine plate?

The pics of the engine plate and stickers are from the sellers, and they will arrive this week. I'll leave the original data plate attached to the original tin and use another tin to rivet the repro plate to. I'm about ready to assemble the engine and I'll be painting it either semi gloss or gloss black. The mini bike collectors buy up these tires, so it's hard to find a decent pair. I'm trying to be as accurate as I can as I restore the tractor. I've been luckily out so far and I can't wait until it's together.
