I recently found a Montgomery Wards Plow-Trac Article #89-1278 SIM 990136A barn fresh with its 42 inch WDM-1393 serial # 85x-85 blade.The original Clinton engine is mostly there but likely has a broken connecting rod. Anyone need parts! I'm looking to take the tractor apart, paint it then reassemble it for use as a snow plow. Can the gear boxes be rebuilt and if so who sells parts? The transmission seems to have all three speeds, reverse and Hi/Low functioning. I was going to pop a tacky Honda 5hp on it so it will be functional. Thoughts or advise?

If gearbox is functioning in all gears and the planetary hi/lo is working I wouldn't mess with it. They are a strong gearbox and don't usually give any trouble. I have a newer 5hp Briggs on mine that works very well. It should be a good snowplow if you have wheel weights and/or chains for it. Have fun....Dave

The grease is really old and the seals that are visible shot. I assume they were designed to run fully packed with grease as I can find no oil ports. The paint is also missing in many places therefore I'd like to get it powder coated. I was going to straighten the bent handles then paint it red with white wheels to match the Honda. Sort of a contemporary trade off. It appears to have been orange. Do you know where I can find the major seals?

The particularly disassembled tractor with much of the grease coated pig poo removed. The one ring seal just hangs loosely. That can't be right. The grease is so old I doubt I can force enough new grease in. With a good deal of effort I was about to free up the shift selector arm. All the gears appear to function

Always thought the 1278 was a Simplicity model FC number 990129 that used a Kohler 4hp engine.

Perhaps it left Simplicity without an engine using number 990136 and Wards added the Clinton engine.

Welcome to GTT. The "SIM" in the model number indecates that it is Simplicity made. Check our Manuals Section for the manuals to your tractor and engine. I adopted a 5 hp B&S to mine 30 years ago, using two 1/2" x 1" x 8" adapters that I made and threaded.

The seals are probably "off the shelf" standard sizes that you can get at a NAPA. Be carefull, take pics as you dissassemble, and most important, have fun. Good Luck, Rick

I'm not sure if this helps, but I have a parts breakdown for an FB, with handwritten part numbers, I assume from a mechanic.

It has a seal number of 8051031, shown for the axle seal. This however, isn't shown on the FC parts breakdown, and there is a transition from the old numbering system to the new system, that must have been implemented between the FB and FC.
