When tractors, excavators, and skidders won't start or deliver rated power, you need answers fast. Our team offers full diesel support, from diagnostics to engine conversions, so you can focus on the field, site, or bush instead of the repair bay.

About Our Heavy Equipment Diesel Repair, Rebuild, Conversion, Overhaul, & Diagnostic Services
Time lost to equipment failure cuts directly into yields and contract deadlines. Modern agricultural and construction diesels rely on high-pressure fuel injection, electronic control modules, and strict emissions systems. A small sensor glitch can spiral into poor fuel economy, power loss, and unexpected shutdowns. Our technicians use laptop-based OEM software, proprietary test benches, and smoke-opacity meters to identify root causes—not just symptoms—before recommending a repair path. That means fewer repeat visits and more predictable uptime for your balers, wheel loaders, or feller-bunchers.
Whether your challenge is a cracked cylinder head, worn injector cups, or a turbocharger slowed by carbon build-up, we combine certified mechanical skill with on-site machining partnerships. We can restore factory tolerances on crank journals, reline sleeves, or re-profile cam lobes, ensuring the rebuilt engine leaves with the same—or better—spec performance it had on day one.
In-Field or In-Shop Service—Your Choice
You shouldn’t have to haul a disabled combine ten kilometers down a gravel road just to change an injector. That’s why four fully outfitted service trucks stand ready 24/7. Each carries a 14,000-lb crane, twin-stage air compressor, welder, hydraulic power packs, oil-recovery systems, specialized pullers, a mobile hydraulic-cylinder bench, and even a 100-ton track press for undercarriage work. Several rigs include 4WD, letting us reach pastures and cut-blocks even spring mud can’t scare us from.
For deeper projects—complete overhauls, block align-boring, or emissions-to-mechanical conversions—we bring the machine into our controlled shop environment on Range Road 232. Here, overhead cranes, heated wash bays, and dedicated clean-room assembly tables keep contamination away from precision components. Because both field and shop crews share the same digital service records, you experience a seamless hand-off no matter where the job starts.
What Sets Black Sheep Apart
- Always Advancing Skills: Every technician pursues at least two factory or vendor certificates per year. Continuous training keeps us fluent in tomorrow’s diagnostics tools and Tier-4 emissions updates.
- Vendor-Backed Parts Warranties: Thanks to direct partnerships with OEM and aftermarket suppliers, parts we install carry the same warranty you’d receive at the dealership—without the downtown commute.
- Local–and Beyond—Coverage: We’re based in Central Alberta but federally regulated, so when a contractor calls from northern Nunavut or a logging outfit needs help in interior BC, we can legally roll north or west without red tape.
- Versatility Across Industries: Grain carts one day, rock trucks the next—our dual-industry experience lets us cross-pollinate best practices and tooling, solving “unusual” problems faster.
- No Comparable Shop Nearby: Simply put, no other service around Red Deer County offers both an on-call mobile fleet and a purpose-built diesel engine facility in one business.
FAQ
What Regions Do You Cover?
We dispatch most calls within Central Alberta because that keeps travel costs down and response times short. However, our federal certification allows us to service jobs as far west as British Columbia and as far north as Nunavut. When distance becomes a factor, we coordinate parts logistics in advance, limiting return trips and keeping your downtime minimal.
How Often Should I Schedule Diagnostic Testing For My Tractor’s Engine?
For equipment logging over 500 hours per season, an annual electronic diagnostic scan and fluid analysis is the minimum. This schedule catches early injector wear and ECM fault codes before they trigger a shutdown during harvest. Lighter-use machines—under 250 hours—can often stretch to an 18-month interval, provided the operator performs regular visual checks and follows maintenance intervals for oil, filters, and coolant.
Can You Convert Older Equipment To Meer Newer Emissions Standards?
Yes. We routinely retrofit legacy Tier 2 and Tier 3 engines with updated after-treatment packages or alternative fuel configurations. The process involves a feasibility assessment, component sourcing, ECM re-mapping, and final opacity testing to verify compliance. Although every machine differs, most conversions deliver better fuel efficiency and prolong the working life of equipment you already own.
