description

This 382-8019 is disc-type rubber torsional damper with 32 mm axial width. It consists of hub, rubber layer and inertia ring, equipped with 12 mounting holes of 17 mm diameter. Mounted on crankshaft front end, the rubber absorbs torsional vibration and reduces fatigue stress on crankshaft, bearings and gear train. Each unit passes crack inspection, dynamic balance and rubber durability test. It is a critical rotating component for overhaul of heavy-duty CAT diesel engines.

FAQ 

Q1：Can 382-8019 interchange with 243-2249 damper?
A：No. 382-8019 has no pulley groove and different bolt quantity, 243-2249 is integrated pulley damper.
Q2：Is this a Reman part?
A：No. It is brand new OEM assembly with new hub, rubber and inertia ring.
Q3：What symptoms will appear when this damper fails?
A：Low-frequency engine shake, front gear noise, crank crack and premature main bearing wear.
Q4：Should I replace it if rubber looks intact during overhaul?
A：Replacement is recommended. Internal rubber aging cannot be checked visually, failure brings high repair cost.
