Good To Know

Q: What is the primary cause of oil seal failure on tractors? A: Dirt accumulation, high operating temperatures, and natural aging of the rubber are the leading causes of seal degradation.

Q: Should I lubricate the seal before installing it? A: Applying a light coat of grease or clean gear oil to the inner sealing lip is recommended to prevent damage during initial startup.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
