8M7437 8M7438 SEAL TRANSMIAAION SEAL KIT PTFFE NBR POM

To maximize the performance and lifespan of your 8M7437 8M7438 seal kits (PTFE NBR POM), proactive maintenance is essential. First, always drain and filter the transmission fluid before seal installation—contaminated fluid can accelerate seal wear. Second, inspect all kit components for signs of damage (such as nicks, tears, or material hardening) prior to fitting, as even small defects can cause severe leaks. Finally, follow CAT’s recommended transmission service intervals; while these PTFE-NBR-POM seals are highly durable, continuous heavy use will eventually require replacement. Adhering to these steps will extend the seal kits’ lifespan and keep your CAT EXCAVATOR LOADER operating at peak transmission efficiency.
