Oil seal 24 horse vertical shaft Briggs.

Replacing shaft seal my question is can you drive seal to machined land area in block. Original seal was flush with block casting. Reason for question is damage on seal area that far out.

If it's damaged to the point of not providing a sealing surface you can't locate the seal lip on it. What kind of damage is it and how wide? If it's just the width of the seal lip, I would drive the seal just past it.

If you can find a thin washer that would lay on the seal casing perimeter, use that on top of the seal to make sure it goes in straight. You'd, then be driving the washer flush with the block.

You can drive it all the way up if you want/need to.

Usually the depth of the bore for the seal is equal to the width of the skirt on the seal. When bottomed in the bore, the seal is perpendicular to the shaft and the skirt/bore contact area is providing another sealing surface. Any change to this alignment can be cause for leaks. Have you tried to clean up the shaft in the seal area with emery cloth?

The depth of the bore is probably about twice the width of the skirt on the seal on these engines. I guess that's good because a lot of times people damage the crank trying to change it.

damaged seal area 24 horse crank

This vertical shaft motor is on a riding lawn mower. Removal of the hydrostatic drive belt is almost impossible. Damage to seal area was a glancing blow from pneumatic chisel. That is reason ask how far seal could be driven in. Could not find a dimisioned diagram to see how deep seal area was versus oil return passage in block.
