replacing oil seal

pfdnothingJuly 10, 2009

I have a 20 HP briggs Vanguard V twin.

Model 351777

Type 1135E1


Code 98121511

Any advice on changing the Crank shaft oil seal

on the PTO side. I would like to change this

with the engine on the tractor if possible .

It is on a Simplicity Landlord tractor , I can

get to the seal just not sure what to use to

remove it . I do not want to cause any damage

to the side plate.

Don't know without seeing it. But there are seal pullers, available at auto parts stores, or use a sharp flat head screwdriver and puncture the steel outer edge and lever it out.

Or drill a small hole in the metal part, run a screw in it and use the screw to pull the seal.

I just changed my crankshaft seals on my B&S V Twin 18 HP 350777 1137 E1. I followed the manual and repair instructions which said to use a big flat screwdriver under the seal to pry it up. The instructions also said to be careful not to damage the bearings. I used a rag under the screwdriver so I would not mark up the oil pan. It does take some slow and steady force but it does come.
Good luck

Whatever method you use to extract the old seal, be careful not to scratch or gouge the bore the seal seats in. A good scratch or gouge to that surface and the new seal will leak where it fits to the cover. If you DO make a scratch, or find a scratch, coat the outside diameter band of the seal with Permatex # 2 sealant (or equivalent product) before installing the new seal.

I used the small hole and screw method that
Walt Conner suggested . It popped right out
and the seal replaced in less than 5 Min.
Thanks for all the suggestions , I will put
them in my Small Engine note book.
