Betsy Posted April 8, 2010 Share Posted April 8, 2010 I have a Mayflower PTO winch on the 2a, its fantastic, but I am now having a problem with a serious oil leak on the PTO output shaft. I have tried rebuilding it using some metric equivalent seals, obtained from an on line supplier, but they were not exactly the same, and lasted about 6 months. Now they have failed badly and its loosing a lot of oil from the PTO. I need to locate some correct size imperial seals, does anyone know where I might get some?

FridgeFreezer Posted April 8, 2010 Share Posted April 8, 2010 I thought most bearing & seal suppliers would be able to sort it out - try bearingboys.co.uk Quote Link to comment Share on other sites More sharing options...
RobotMan Posted April 8, 2010 Share Posted April 8, 2010 I thought most bearing & seal suppliers would be able to sort it out - try bearingboys.co.uk Given that the Americans still use a lot of imperial stuff there should be supplies available. Good Luck Quote Link to comment Share on other sites More sharing options...

David Sparkes Posted April 9, 2010 Share Posted April 9, 2010 Don't overlook the fact that the seating area the seal rubs against may be damaged by grit, or simply wear. If so, either try locating the replacement seal to a slightly different place (perhaps by not putting it fully into the housing), or by using the resurfacing shims - the correct name and supplying company escapes me at the moment, but others will know (and help!!).

Betsy Posted April 9, 2010 Author Share Posted April 9, 2010 Thanks for the replies. I have not got the exact dimensions to hand, but I seem to recall that they were a very odd size and it was Simplybearings who got the metric versions for me. The shaft is in good condition. The original seals were unusual in that the sealing lip was a V shape without a lip and spring. The one supplied were traditional lip and spring items. In case anyone has done this before, its the smaller shaft, that has the output to the winch on one side, and the shear pin housing on the other. The shaft goes straight through the PTO and has the same seal on each side. Quote Link to comment Share on other sites More sharing options...
Jon White Posted April 9, 2010 Share Posted April 9, 2010 When I rebuilt mine I got seals from BRT bearings IIRC - they had no problem sourcing them. IIRC they're 3/4" id, 1 1/4" od and 1/4" thick. Jon Quote Link to comment Share on other sites More sharing options...
Betsy Posted April 13, 2010 Author Share Posted April 13, 2010 Just for information, I measured with electronic calipers, and the output shaft of the Mayflower PTO unit has a diameter of 1.25 inch, and a housing of 1.62 inch. The seal is .25 thick. I ordered the exact size seals from simplybearings. I have ordered the R23 version, with double lip. Hopefully they should be fine.
