Small Engines (Lawn Mowers, etc.): Toro Super Recycler / B&S OHV engine Oil leak from Crankshaft, engine oil leak, oil drain plug


Question
Hello, thanks a lot for taking the time to listen to my question.

I have a Toro Super Recycler lawn mower, model 20057, about three years
old.  Recently, I noticed that it was leaking oil on the bottom, resulting in the
bottom of the deck being soaked in oil. It really doesn't leak that much- I can
mow three or four times before needing to top up the oil- but it is irritating
to have oil soaking the deck. My thoughts are that the crankshaft seal is bad,
because I have tightened the oil drain plug and that did not solve the issue.
How hard is it to change this seal and do you know of any good instructions
on how to do so?

Thank you

Nick

Hello Nick:

**Remove the Blade and Blade Adapter. Sand the Crankshaft with Emory Cloth Sand Paper and Remove All the Rust and Burrs. The Using  a Small Flat Head Screwdriver, Pop Out the Old Seal. Sometimes, you have to Use a Small Cutting Chisel and Cut the Seal First. I Use Pipe of the Same Diameter (Close as Possible) and 3" Longer than the Crankshaft with an End Cap on it. Place the Seal Into the Engine Base and Get it Started. Place the Pipe Over the Crankshaft and Drive the Seal Into Place Sometimes, if you have a Full Tool Set; you can Use a Deep Well Socket to Drive the Seal Into Place. Make Sure is is Deep Enough to Miss Hitting the End of the Crankshaft.** On this Mower the Blade Adapter has the Pulley for the Self Propelled Belt. The Belt will have to be Removed from the Pulley and from Around the Crankshaft. You can View a Breakdown/IPL of the Mower at this Site Addy, https://lookup3.toro.com/partdex/default.cfm and Select Start Parts Viewer. Now Enter the Model Numbers. Now Select View Assembly Drawings. If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck
