Kubota and Yanmar engines power a wide range of machines on construction sites across Chicagoland. Compressors, telescopic handlers, and utility equipment keep crews running through every phase of a build. When any of it goes down, most shops in the Chicago area will not work on it.
Masterman Heavy Equipment Service LLC provides rapid field diagnostics directly at your job site. We perform on-site repairs when possible, and utilize our fully equipped Schaumburg facility for major engine rebuilds, heavy teardowns, and complex overhauls.
Kubota engines show up inside excavators, compact tractors, generators, and skid steers across Chicagoland construction sites. We specialize in Kubota engine diagnostics. We come to your site to identify the problem and fix minor issues on-site.
For full engine overhauls or heavy internal repairs, we transport the unit to our professional repair shop in Schaumburg.
Yanmar engines run inside mini excavators and a wide range of machinery across Illinois job sites. Like Kubota, Yanmar is a brand many local mechanics avoid. We do not.
We diagnose Yanmar engines in the field, handle rapid repairs on-site, and coordinate in-shop rebuilds when a complete overhaul is required.
Ingersoll Rand compressors and telescopic handlers are workhorses on commercial sites. A compressor failure cascades fast.
We dispatch to your site across Chicagoland to diagnose the failure. If the unit requires a major rebuild that cannot be done safely in the dirt, we bring it back to our facility.

Kubota and Yanmar are not brands every mechanic works on. When your current shop says they cannot touch it, or when the dealer is booked out for weeks, that is where we come in. We know these engines and work on them every week.
Construction equipment is not easy to move. A down compressor or a Kubota-powered excavator is not something you blindly throw on a trailer. We drive to your site to diagnose the failure exactly where it sits in Schaumburg, Elgin, Aurora, or anywhere across the metro. If it is a minor fix, we handle it in the field. If it requires a major teardown, we bring it back to our fully equipped shop. You get mobile speed with heavy-duty repair capabilities.
If your job site has a Kubota engine issue on one machine and an Ingersoll Rand equipment down on another, we handle both. You do not need to coordinate two separate service calls with two separate vendors.
You call or text Robert, not a dispatcher. He tells you directly whether he can get to you, when he can be there, and what the repair will likely involve. No runaround. No callbacks from someone who was not on the original call.
We work with general contractors running active commercial builds across Chicagoland. We work with civil construction crews that depend on Ingersoll Rand equipment to keep a job moving. We work with excavating companies whose Kubota-powered machines are the core of their daily operation.
If your construction fleet runs any of the equipment listed on this page, we can keep it in service.
Yes, we perform field diagnostics and rapid repairs on Kubota engines at job sites across Chicago, Schaumburg, Elgin, Naperville, and the full Chicagoland area. If the engine requires a complete teardown or major overhaul, we utilize our fully equipped repair facility in Schaumburg.
Yes. Yanmar engines appear in many different machines. We service the Yanmar engine regardless of which machine it is installed in. If your equipment runs a Yanmar engine, we can work on it.
Yes. We travel to your site and service Ingersoll Rand equipment and telescopic handlers on-site. A compressor down on an active build is a same-day call — contact Robert directly.
No. A complete engine rebuild requires a clean, controlled environment and heavy machine shop tools that cannot be safely deployed in the dirt on an active construction site. We diagnose the engine failure in the field, and if a full rebuild or replacement is required, we transport the machine or the engine to our professional shop in Schaumburg.
We offer same-day response for urgent breakdowns across Chicagoland. Call or text Robert directly - he answers, not a dispatch center - and we will get to your site as fast as possible.
Yes. We schedule regular preventive maintenance visits for construction fleets in addition to responding to emergency breakdowns. Call Robert to discuss what a maintenance schedule would look like for your operation.
