Engine and Powertrain Diagnostics
The latest Komatsu products rely on complex electronics and precision powertrains. These advanced components enable the equipment to handle a heavy load and operate more efficiently than ever. We utilize advanced diagnostic tools to troubleshoot engine fault codes, transmission slippage, and power loss. Whether it is a clogged fuel system or a sensor malfunction, we identify the root cause quickly to prevent recurring issues.
Custom Fabrication and Welding
Does your equipment experience heavy, repeated use in challenging work environments? Our extensive custom fabrication capabilities can keep your equipment productive, safe, and serviceable. Our fully equipped in-house welding shop allows us to reinforce stressed chassis components, rebuild worn buckets, recondition hard-facing ground engagement tools, and perform other tasks that go well beyond standard fixes.
Undercarriage Repairs
The undercarriage absorbs much of the punishment when operating your Komatsu equipment. Prime Source's dedicated undercarriage shop can optimize the undercarriage's stability and performance. Our certified technicians will replace worn track shoes, perform track tensioning and alignment, and implement preventive measures to minimize wear on idlers and sprockets, keeping your equipment moving smoothly over the most rugged terrain.
