Tuff Torq Transmission Fill & Vent Cap Set for K46 Gearboxes — OEM 187T0136300/168T2024250, Genuine Sealing

This pair of OEM Tuff Torq caps restores correct sealing and venting for many K46 transmissions. Sold as a new, bulk-packed set, it replaces older part numbers (187T0136300 replaces 168T2036300; 168T2024250 replaces 19485924252) so you can match service parts quickly. Use the caps to maintain proper fluid fill levels and controlled venting, and always confirm fitment against your owner's manual or parts list before installation.

How do these caps fix common transmission fluid issues?

Worn or missing fill and vent caps can allow contamination, fluid loss, or pressure imbalances. Installing the correct OEM caps helps re-establish a proper seal and a controlled vent path, reducing the chance of debris entering the gearbox and helping the transmission keep the intended fluid level.

• Fill cap seals the fluid fill opening to prevent spills and contaminants.
• Vent cap permits pressure equalization without letting dirt in.
• OEM fit minimizes the risk of leaks from mismatched aftermarket pieces.

Which transmissions and models are these parts compatible with?

These Tuff Torq caps are intended primarily for K46-series transmissions, but fitment depends on exact model and production date. Always consult your equipment’s parts listing or owner’s manual to confirm the listed part numbers match the unit you’re servicing.

• Designed for most K46 transmission variants.
• Replaces older part numbers for easier cross-referencing.
• Check the machine’s manual or parts diagram before ordering.

What does installation involve and what should I watch for?

Installing these caps is typically straightforward—remove the old caps, clean the fill/vent openings, and thread or press the new caps into place per the manual. Make sure mating surfaces are free of debris and that the new parts seat correctly to avoid leaks or restricted venting.

• Clean the fill/vent area before fitting new caps.
• Tighten or seat per manufacturer guidance—do not overtighten threaded caps.
• Inspect seals and nearby fasteners after first operation for leaks.

Why choose genuine Tuff Torq caps instead of generic replacements?

Genuine Tuff Torq parts are built to match the original specifications, which helps ensure proper fit and long-term performance. Using OEM components reduces the chance of fitment issues, unexpected leaks, or premature wear that can arise from poorly matched aftermarket parts.

• Manufactured to original equipment dimensions and materials.
• Cross-replaces legacy part numbers to simplify sourcing.
• Sold new and bulk packed for service convenience.

If you maintain equipment regularly and want a correct-fit, manufacturer-specified fill cap and vent cap, this Tuff Torq set offers direct compatibility—provided you verify the part numbers against your machine’s manual.
