05-14-2007, 02:58 AM
48" snapper wb transmission is slowly leaking grease, i just noticed this, but i bet its been doing this for a while. where do i add grease? do i need to take it apart to add grease?
at this point being my primary mower i would just like to add grease once a week since it is a slow leak. in the fall i will take it apart and fix it.
what is the easiest way to add grease?
if i have to take it off/apart, do you have any tips?
the pictures show the leak as well as various views so you know the type of transmission.
thanks so much in advance, if this trans went out midweek i'd be so screwed next year i'll have a second mower, but right now im counting on this thing big time.

That looks like a peerless trans, which should be sealed and supposedly never need maintenance. Looks like a damaged gasket to me. It looks to me like you have to remove the trans, take the top half off, scrape off the old gasket, replace with a new gasket, add or change the proper gear oil, then reassmble and reinstall.

This gearbox takes bentonite grease, There is no gasket between the case halves they are a machine surface. You can remove the top case half without removing the gearbox from the unit.
Remove the shift arm, Loosen the allen (detent) screw then slide the case over the shift fork shaft.
After servicing/installing grease wipe case mating surfaces clean and apply a thin bead of Loctite gasket eliminator then assemble.

If you want the easy way out drill a hole in the rear of the case ,tap it for a grease zerk. the aluminum shavings are soft and wont hurt the internals . Then just grease it a few strokes at your regular service interval. Too much grease won't hurt these trannys.

Yeah man, I've taken more than a few apart, I can tell you some do's and dont's:
When it runs for a bit, touch it carefully and see if it gets HOT!
By HOT I mean like it almost burns your hand hot.
If so, that would require another explanation, but do tell if.
You may wish to order a Tecumseh manual from J.Thomas, they're like 15 bucks.
You'll likely have to remove the shifter...
Not much to it, except mine doesn't have those wires... :confused:
Oh well, it's not so bad.
- DO get a tube of that Bentonite grease, don't use nothing else!
> I'm serious, you'll waste your time if you do.
- Goop that stuff in there, don't overfill but do fill'er up pretty decent, more is better but try and leave a little air and watch you don't get any on the gasket mating surfaces.
- You should try and clean the mating surfaces, but the aluminum scratches easy so I use a fingernail to scrape (pita and slow going but it works).
- For the gasket, I used a tube of hi-temp make-a-gasket from Advance, get some of the best stuff, hi temp just in case.
There is some yin yang to it:
Goop the grease first, and you will have some old gasket pieces fall in.
Goop the grease last, and you will get some on the new made-gasket.
Since the gasket itself is like a rubber, I'd goop the grease first, won't hurt if a few pieces fall in.
I don't care so much how you get the cover off, tools wise, but when you put it back on be VERY careful!!! Do NOT use air-powered or electric tools to do it! The cover and base are made of aluminum, first hand-tighten the bolts, then use a ratchet but just snug them on do NOT tighten them up much!
> If you over-tighten one, you will strip it, it don't take much.
>> If you strip one it should still be ok, two is borderline, I'm telling you be careful.
Hard to explain where exactly that maximum pressure point is, a torque wrench would be best, but so is practice... I've stripped a few things on aluminum blocks before, once you do it 2-3 times you know just what it takes, again one is ok to strip but just be careful.
> If you do strip one, just kinda git it on easy, best as it seats, don't keep turning it, it won't be on real good but just hang it in there and let it go.
