I replace the front seal in the PTO gearbox on a rotary cutter. The procedure would be very similar for on equipment with a PTO gearbox, finish mower, tiller, post hole digger etc.
Good evenings Sir, Great tips ( tap screw ! ) on how to remove of the front seal 👌🧐👍 and also on how to installed too 👍🧐👌 Have a safe week Sir Cheers 😇🙏🍻
That went good! Do you know if the shaft had any play? On my belly mower (Bolens) the gearbox had a loose shaft, I had to remove (or add?) a few shims so the tapered bearing keeps the shaft tight and well centered. Thanks Roger!
This video was very helpful; however, I would appreciate information on how you were able to determine which replacement seal to use. The condition of the rotary mower appears to make it difficult to read brand, model and serial number information in order to determine a part number and even manufacturer of the gearbox.
The seal will have numbers on it that will be a part number. Or you can measure the Id of the seal which is the shaft diameter and the OD of the seal which is the ID of the hole in the gear box it sets in. A real parts house will be able to do this for you. Try not to totally destroy it and take it to a NAPA if there good and if you know someone knows what there doing Advance or Orielys can do the same or a hydraulic parts house can and probably has it in stock. Oil seals are oil seals there universal.
I’ve watched a few these and I’m a little scared to go to drilling on my gear oil box. My seal is more buried in there tha. yours. If you’re careful could you just spend a little more time and get the old seal off with a screwdriver? Whatever dings and scratches you make doing it can’t be any worse than the ones you make hammering the seal back on IMO but I don’t know for sure obviously.
