GC1700 series gear box oil change on mmm.

[Jonohio]

Another day of learning about mmm decks.

1. Guess how many grease zerks there are on an MF mmm deck.
If you guessed 6 or 8 . . you'd be wrong. The answer is 12 if you include the following:

Rear deck wheels 1 each times 2
Front deck wheels 2 each x 2
Spindle 1 each x 3
Tension pulley 1 each x 1
Gear box shaft 1
Shaft to mid pto 1

Plus there are 2 spots to apply grease that don't have zirks (gear box race and shaft to pto snap ring)

2. I always use a high temp RED grease so it shows up. Last year I greased my deck 3 times . . Always till grease showed . . Or 3 pumps where I couldn't see (covers on etc.) Well today I had all the covers off and cleaned everything up. Then I greased everything. I was a little surprised how the spindle zirks I pumped 5 times each and still didn't show grease coming out . . So 3 more pumps each and dark grease came out (not my red color). So obviously 3 times last year x 3 pumps each on each spindle had not driven old grease out and now 8 pumps each is finally pushing out the old grease. My point is . . The spindles sure seem to take considerable grease.

Woah, I was surprised today too when I greased my MMM. The spindles took a ton. I need to order another couple tubes from amsoil.....

I know it is over kill, but I grease my deck before every use. I hit the drive shaft about every other use. Knock on wood, but I have never had a spindle bearing go down in any of my mowers that had grease fittings.

Wow . . Every time ???? That would be more than once a week for me lol.

I never know what is the best "type" to use because I want to use one type for all my regular grease efforts and then I have a separate gun for non-important greasing needs.

My regular grease is a high temp red colored product by Mystic. I thought the high temp would be preferred for spindle lubrication . . Plus the red is easy to see.


Then for low end needs like wheels on wheelbarrows or carts I use just the lithium dark colored choice for my alternate uses.

Any suggestions on a better choice or type for my tractor and mower equipment (than my red high temp) ?

I use Lucas red tacky mostly, but I will use any EP grease if nothing else is available. I mow for over two hours straight each and every time I mow. I use my air grease gun and that cuts down time. Grease is cheap and I mean to get my money's worth out of this machine.

Jonohio, I noticed the same-- those spindles do use up the grease pretty well; they can take a number of pumps to re-fill. Must be a chamber in there or something.

I haven't used my Deck yet MF 2325, Bought it off CL for 600 bucks, Think I'll go ahead and service the fluid and make sure I grease it all up before I attempt to mount it up for the first time. Purchased a Titan Ballast box off Ebay so I can take off the Hoe for storage instead of weight.
