Detailed Description

Built for engine lubrication service, Baldwin B7121 is an oil filter specified for Kobelco equipment and Mitsubishi trucks that require the listed dimensions and thread pattern. The filter measures 186.5 mm tall with a 108 mm outside diameter and uses an M26 x 1.5 thread, making it a direct-reference choice when matching the original filter specification.

What It Helps Address

  • Oil contamination from normal engine wear and debris
  • Restricted oil flow caused by a clogged filter element
  • Incorrect filter fitment from mismatched thread or diameter
  • Oil seepage at the sealing surface when the gasket is worn or missing
  • Service interruptions when replacing a worn Kobelco or Mitsubishi oil filter

Installation Notes and Tips

Verify the M26 x 1.5 thread, 7 11/32 in. height, and 4 1/4 in. outside diameter against the removed filter before installation. Clean the mounting surface, confirm the integral gasket seats evenly, and tighten the filter to the equipment manufacturer’s service specification. For best results, prefill only if the engine service procedure calls for it.

Quality Assurance

Baldwin filtration products are built to meet professional service requirements for heavy-duty engine maintenance. Confirm part number B7121 and the listed dimensions before installation to ensure the correct replacement for your Kobelco equipment or Mitsubishi truck application.
