My engine on my Simplicity tractor lost its lower oil seal.
I had to remove the 8HP engine and associated parts from the tractor.
I didn't have to break down the engine, but removed old seal.
Cleaned the area and used Loctite to re-install new oil seal
Used JB Weld under the seal to hopefully keep the seal in place.
Put engine and all associated parts back on the tractor. Engine did good and no leaks.
Replaced Tube breather on the Breather Assembly too.
Tractor is 48 years old and it's nice to know I can still get parts for it.
THANK YOU !!!!!!!!!!!!!!!

They said I could have it so when I couldn't get it started I began looking into it and found the connecting rod and piston damaged on the number one cylinder. I ordered the parts necessary and completed the repair. The web site is very easy to navigate and shipping is quick.

The dummy ran it without checking the oil level, signed The Dummy
First I had to disassembled the Baker Chipper Vac in order to get the engine off. Pulling the rotor head off the crankshaft end took some time with a shop made puller. Once I got that off it was easy enough to split the case and determine that the rod and piston along with the crankshaft surface were ok. What had seized was the crank bearing on the inside of the case. Once I got lubrication to it it started to turn freely. At that point I decided to go no further and ordered parts from Ereplacementparts. Engine is probably 30 years old but Ereplacementparts had what I needed for the Briggs and Stratton.

    Great source for parts
    All of my equipment, as like me, has alot of age on it. The ability to get the parts I need guarantees that the equipment will still be productive as it ages further

    Replace an oil seal on an old engine.
    I was surprised to find an oil seal to replace the one on a 42 year old engine. The seal fit perfectly and solved the problem. Great service!!
