24hp briggs and stratton

[Outdooz]

I dont know the model number. But what is the cause of this?
A oil leak from the crankshaft..
Replaced the seal but same problem
Replaced the seal again but still problem
The new seals didnt even fix it at all.
What could be the cause?

Your getting the Wrong seals...
use a dial caliper and measure your shaft OD and the housing ID...
Also check for gouges and scratches at the points of seal...

Make sure the seal is where it is actually leaking, also make sure you are installing it correctly (not damaging it as it is becoming installed. Perhaps for whatever reason the oil sump hole has been worn out some and even the correct seal won't work.

I have seen on more than one occasion on the twin briggs were the crankshaft has wallowed an egg shaped hole in the lower sump bearing causing the symptoms you describe. It usually results in a groove worn in the crankshaft requireing both the sump and the crankshaft to be replaced. Has also been linked to a bad electric clutch that causes arcing between the sump and the crankshaft causing a welding effect across the oil barrier.
