I am looking for a cross-referenced common seal number for the input lip seal (Jacobsen 545428) on the Hydrogear hydrostatic transmission used on a 1968 Jacobsen Commercial 60 mower (serial numbers 4672 and up).  I have downloaded the repair manual supplied by KennyP, listing the OEM lip seal number. Picture of hydrogear attached. Thank you in advance.

Sometimes, there is  a number and/or brand name on the face of the seal.  ...These would be from the seal manufacturer, as Jacobsen did not make their own seals.


If the old seal can be removed without too much damage, you may be able to get a replacement from an auto parts store, or a bearing supply (a.k.a. power transmission).


Lip seals are commonly sold if you know the shaft diameter (seal i.d.), the housing diameter (seal o.d.) , and the thickness (width) of the original seal.
