Mitsubishi 1145A080 — Timing Belt Tensioner
Overview
Timing belt tensioner Mitsubishi 1145A080 maintains constant tension on the engine valve timing belt assembly in diesel power units. The unit prevents timing belt tooth jump across the camshaft and crankshaft pulleys, preserving exact valve synchronization. Constructed with a cast metal body, it houses an internal hydraulic piston and fluid damper mechanism. Main body dimensions measure 85x55 mm, featuring a 10 mm piston rod diameter and 68 mm mounting hole spacing. Original equipment reference number 1145A080 matches factory specifications. Consistent hydraulic rod pressure eliminates belt slack during rapid engine speed changes and thermal expansion cycles.
This part fits Mitsubishi L200 KB4T, Pajero Sport KH4W, Montero Sport and Challenger models fitted with 2.5 DID 4D56 turbo diesel engines produced between 2005 and 2015. Replacement is required during scheduled timing drive maintenance every 90 000–100 000 km, or when fitting a new timing belt and idler pulleys. Common wear indicators include fluid leakage past the piston seals, ticking noise from the timing cover during cold starts, and reduced tensioner damping resistance. Replacing a failed hydraulic unit prevents belt slippage, uneven engine running, and potential valve-to-piston contact caused by altered valve timing.
