Yanmar Equipment Repair in Fontana
Yanmar's ViO zero-tail-swing excavators work the tightest sites in the region — and whatever badge sits on the hood, Yanmar diesels quietly power half the compact machines and generators in the yard. Our Fontana shop looks after Yanmar excavators, carriers and engines across their hydraulic, drivetrain and electrical systems. We're an independent shop, not a Yanmar dealer — compact-machine work carried out to a rebuild standard.
Fontana, CA · Independent Yanmar service
The Yanmar work we handle week in, week out
Travel and swing motor servicing on ViO and SV excavators; hydraulic pumps and cylinders; repairs to Yanmar's TNV diesels — both in Yanmar's own machines and in the other brands those engines hide inside; rubber track and undercarriage work; and the cooling and charging faults that machines living in dust and heat collect. Small machines, same discipline as the big ones: teardown, documentation, written quote, rebuild, test.

Yanmar equipment repair · Fontana, CACompact machines, held to full-size standards
Too many shops treat mini excavators like throwaway equipment. Here, a ViO gets the same measured teardown and written quote as a 30-ton machine — because to the crew running it, the job it's on matters just as much. Pick-up and delivery are free where applicable; regular hours are Monday–Friday, 6 AM to 5 PM, and the rush line runs around the clock, every day of the year.
- Hydraulics and motors on ViO and SV excavators
