Simplicity Landlord Hydro lift input shaft seal NLA, replacement?


Recommended Posts

Hi all,

I cant seem to find an answer after a good bit if searching.  Working through the hydraulic lift assembly now on the Landlord 2012 restoration project.  All orings have been located through various searches but and cant seem to find the latest on the pump input seal.  Looks like the factory part number is 157437.  Anyone know what we use now days to seal up the shaft that drives the gears? 

Thanks much,

I believe it is a Parker-Hannifan pump. It is possible that a hydraulic shop may be able to get a complete kit or parts through that vendor.

Oil Seal P/N 157437, is included in the Parker repair kit P/N 686632K (Buna-N) or P/N 745083K ( Viton). FYI, I purchased the Buna-N kit in 2021 for $64.85.

The oil seal is 0.50" ID X 1.00" OD X 0.25 wide. Should be able to use Timken/National P/Ns 471442 (Buna-N) or 471442V (Viton) or SKF/CR 4985 (Buna-N).
