Mitsubishi 3231A038 — Transfer Case Oil Seal
Overview
Transfer case oil seal Mitsubishi 3231A038 seals the output shaft of the transfer box assembly, retaining gear oil and preventing contamination from dust, mud, and moisture. Manufactured from heat-resistant fluororubber FKM material with a steel reinforcement ring and a stainless steel garter spring. This radial shaft seal operates effectively across temperatures from -40 °C to +150 °C and maintains elasticity when exposed to synthetic gear oils. Standard dimensions measure 40 mm inner diameter, 62 mm outer diameter, and 8 mm thickness. OEM reference number Mitsubishi 3231A038 supersedes former part numbers MD758763 and MD701430. An integrated dust lip acts as a primary barrier against external abrasive debris.
This transfer box oil seal fits four-wheel drive vehicles including Mitsubishi L200 KB4T 2.5 DID (2005–2015), Pajero Sport KH4W 2.5 DID and KH8W 3.2 DID (2008–2015), and Pajero IV V80 3.2 DID and V90 3.0 V6 (2006–2021). Replacement becomes necessary upon noticing oil seepage at the transfer box output flange, fluid loss in the transfer case, or during major drivetrain overhaul. Rubber hardening, thermal cracking on the sealing lip, or mechanical wear cause fluid leaks, leading to gear damage from insufficient lubrication inside the unit. The exact fit design fits directly into the factory transfer case housing without modification.
