I need to replace the seals on my Troy-Built Pony tiller. 6 hp, ser.# 121811201149. I can not seem to remove the tine shafts. I have pulled the bolt thru the shaft but cannot budge it. Does anyone know what I am doing wrong. Is there a trick? Thanks

Go to this website and type in PONY for your model number and find your operator manual by your serial number. The operator manual should have detailed instructions on how to replace your seals.
On the Horse model you remove the wheels and then carefully use a couple of screw drivers to pry out the old seals being careful not to scratch the wheel shaft sealing area. Then polish the wheel shaft with fine emery cloth to remove any sharp edges. Then grease the wheel shafts and carefully slide the new wheel seals on and use a piece of plastic PVC pipe cut square that will slide over the shaft and gently drive the seal to the depth the old seals were installed at. You dont even have to drain the gear oil. Getting the wheels off the wheel shaft is sometimes a problem if they are rusted on. if you can get the wheels off its not to hard to change the seals.

From the #HH60 I think it is a 6 horse power,tecumse engin whith a horizontal crank shaft.

Your tiller is a pony.

Have you tried soaking the shaft area with either PB Blaster or Deep Creep penetrating oil. Try this for a few days before trying to tackle getting the tine attachment off.

1. Remove belt guard on left side
2. Remove belt, large pulley on gearbox.
3. Remove throttle cable, idler pulley cable and shift handle.
4. Remove engine, handle, wheels, tines cover and tines.
5. Lay gearbox on side on two sawhorses, left side facing up
6. Remove all the nuts on that side. If the three shafts have corrosion, use sandpaper to remove.
7. Pry the two halves apart, then hammer the ends of the three shafts to push through their bushings. Use brass or wood to avoid blossoming the shaft ends. When shafts are through their bushings, the right side will fall away.
   

It's 90 weight gear oil but most likely the output shaft seal has been gone for a consdierable amount of time and has leaked out and is just now making noise, they don't normally make noise right away after the oil runs out. put oil up to the plug fill hole and watch if it runs out the shaft seal if it does then it will have ti be repaiered.

on my pony the disc came off when i removed all of my tine shafts. then i pulled the old seals out an drove the new ones in

sounds like the shaft is either bent,or the inside diameter is worn and the shaft tube needs to be replaced.

The serial number is located on a flat spot just above the right wheel shaft where the gear housing and the top gear cover meet. It will be a six digit number stamped in the metal.

If the seal fits over the axle shaft it should be ok. be sure your axles are very clean as not to ruin the new seals when applying them. probably a good idea to replace them as a pair (right and left side) to save you time down the road.
