Detailed Description

Timken 224205 is an engine camshaft seal engineered for controlled oil retention at the camshaft interface. Its reinforced outer case supports installation integrity, while the ribbed inner diameter helps the seal conform to minor shaft imperfections for a more consistent fit. The internal exclusion design and vented lip area work together to help reduce contamination and heat-related wear. This part cross-references National 224205 and SKF 550237 for the same application.

Compatible With select 1981-1995 Toyota Pickup, 1988-1995 Toyota Pickup, 1988-1990 Toyota 4Runner, 1992-1994 Toyota 4Runner, 1993-1994 Toyota T100, 1981-1987 Isuzu Pickup, 1984-1987 Isuzu Trooper, 1984-1985 Chevrolet S10, 1984 Chevrolet S10 Blazer, 1984-1985 GMC S15, and 1982 Chevrolet LUV applications. Timken 224205 is a practical replacement choice when servicing camshaft oil leaks on these vehicles.

What It Helps Address

• Oil seepage at the camshaft seal area
• Contamination entering the engine sealing surface
• Heat-related seal wear from poor lubricant circulation
• Leakage caused by minor shaft surface imperfections
• Seal damage during installation on worn housings

Installation Notes and Tips

Inspect the camshaft, housing bore, and sealing surface before installation. Clean away old seal material, oil residue, and debris so the new seal seats evenly. Confirm the CW-Clock Wise helix orientation and verify dimensions against the original part before assembly. Proper alignment during installation helps prevent lip distortion and early leakage.

Quality Assurance

Timken sealing products are built around precision sealing designs and durability-focused construction for engine service work. The 224205 follows Timken’s approach to controlling lubricant loss while helping keep contaminants out of the sealing area.
