3-tn63-2 starting motor
Looking for a 3tn63-2 starting motor? This is an aftermarket replacement built to the original equipment drawing — same mounting interface, same fitment geometry, no rework required at installation.
Why this part fails — and what we do differently
On a hydraulic 3tn63-2 starting motor the clearance between mating parts is measured in microns, so ‘close enough’ is not close enough. We machine and assemble to OEM specification, pressure-test each unit and record the values. Send the machine serial number and we confirm the exact variant for the machine in writing before you pay.
Ordering, packing and warranty
We ship single units worldwide and consolidate full containers for distributors. Every 3tn63-2 starting motor is individually boxed and labelled with its part number, and pre-shipment photos and dimensional checks are provided as standard. Warranty against manufacturing defect: 6–12 months depending on the part category.
