Be carefull with gear oil. Your typical 80w90 and rearend gear oils are Hypoids wich will attach any yellow metals in the bearings. Just make sure what your bearings are made of and you shoulb be ok. If you wanted you could use a 00 semi- fluid grease. Its primarily used in tractor trailor axles. hit me up if you have oil abd lube questions. As thats what i do for a living. Lol
Sickle bar mower refurbish
9
So I got these 2 mowers a few weeks ago, my ad on Craigslist really payed off. I got the 2 mowers, The Custom, the ST12, a buncha mule drives and random Sears parts and 3 3 point hitches for $400.
Model # 842.260020
Serial # 86260 and 97522
Neither of them are in working order but both are complete. As you can see in the first 2 pictures, one of them is severely twisted and broken but it's actually in better shape as far as rust goes. So all it's good parts will be switched to the other one.

The shaft and mounting assembly is much better on the twisted one, so it will be switched along with the rest of the pulleys.

Everything is coming apart surprisingly easy. This pulley came off with minimal effort with a pulley puller.

Took the arm off that makes the knives go back and forth off to make sure its crankshaft isn't frozen. It's not.

I assumed the mule drive gearbox's would have oil in them since they have a drain plug, but they don't. The grease? is hardened into a brick. Are they suppose to have gear oil in them?

Definately sounds like there was a reaction in the two greases. Some 75w90s do and some dont. Its more important to find out what materials you are working with. It would be of benefit to use a good hypoid for that application due to shock loading. I doubt there are any yellow mwtals in ir but unless you check its hard to say looking at the pics. If you have a good auto parts store go look at their qt bottles of gear oils. Royal purple should be a good synthetic and about $17. A little pricy but the synthetics will last a lot longer in the abuse you will most likely give it.
