Small Engines (Lawn Mowers, etc.)/John Deerr 445 Crankshaft Seal leaking


Hello I have a John Deere 445 with Kawasaki FD620D engine. I noticed a small amount of oil leaking around the crankshaft seal during pre winter prep. Can the seal be removed and replaced with out a complete tear-down of the motor? I looks like I could use a "gasket hook" to remove the old one and then just press the new seal in place with minimum dissembling.  
Thanks Eric

It can be removed without just have to be careful.  I would remove the engine to replace the seal and make sure the crankshat is free of all rust and smooth.  I would sand the shaft with find sandpaper.

Installation will require some type of a driver.  A piece of PVC pipe usually works well.  They sell seal protector tools but old microfiche card or a plastic bottle can be cut and wrapped around the shaft to protect the seal when installing.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
