Briggs oil seal

Fast turn around spot on.

8 May 2018

7/8" crankshaft bottom oil seal

Good product good price , this is a reasonably common issue with the older 3.5/ 3.75 Sprint BS motors . The bottom seal sits with it outside facing the dirt and the inside at the bottom of the mowers sump so its lubed by any dirty oil and any sunken metal particles . Most mowers will only ever get a 100% full oil change when this seal is replaced as it needs to be upside down to easily replace. Remember to clean the crankshaft before the new seals is replaced.
