Re: Re: Gearbox Output Couplings & Oil Seals

The surfaces on my output coupling shafts were a little scored and I had already bought the sheath kit so I put them on. Very simple process with the small tool provided in the kit. [ 💡 info provided by Den Hewitt – If the couplings are worn then you can use SKF Speedi Repair Kits part number 99146. I have used these. See my article in Floating Power Vol 25 2011 Issue 3 May/Jun. 💡 ]

Very lightly tap around the edge, not too hard. Every few taps, I removed the tool just to check the sheath was sliding on straight.

With the new sheaths on, you need to put the output coupling back on the splined shaft of the gearbox. Again, one slid on easily, the second needed a little help. I first checked for burrs on the splines then gently lined up the spines onto the shaft. Tapped a block of wood to start the coupling on its downward journey. Once there was enough thread showing, I placed the washer and nut on and tightened using my torque wrench and of course my manufactured tool (you may as well use it is you have made it.. right 😀 )
