Product Overview

A cap that no longer seals can let dust and water reach the tank opening, while a blocked vent can create its own operating problems. This replacement is meant for machines that use the same neck, seal, and vent arrangement as Cat 142-8937.

The same reference appears across many machine families. Use the part number and tank location as the main fitment checks, especially when a model has more than one cap.

This is an aftermarket replacement part and is not manufactured or supplied by the original equipment brand.

Compatibility Notice

Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown. Model names alone may not guarantee fitment. Compare the original component, reference number, connector or mounting design, dimensions, and any serial-number or production-date break before purchase.

Frequently Asked Questions

Q: Is this a fuel cap or hydraulic cap? A: Match 142-8937 and the original tank location; do not choose only by the machine model.

Q: Will it fit every 908 or 926? A: Serial number and tank configuration can change, so the original reference is the best check.

Q: Can a bad cap cause operating trouble? A: A poor seal can admit contamination, and an incorrect vent arrangement can affect tank pressure.
