35230-39DL Old 2163-36 Transmission Main Drive Gear Double Lip Seal

$ 4.39

Excellent Quality Double Lip Oil Seal. I have Used This Seal For Years And When Properly Installed They Will Not Leak. I Use a Little Liquid Pipe Sealer On The Case To Help Seal And Add Some Lubrication When Pressing In. I Also No Not Use The Cork Or Small Tab With This Double Lip Seal. Check The Main Gear Spacer That The Seal Rides On. If The Back Of It Is Chewed Up And Not Smooth You Will Never Maintain Your 125-135 ft lb Clamp Load On The Sprocket Nut. This Will Lead To A Loose Nut And Seal Leakage.
