Introduction: Why the Deutz Engine Matters in a Bobcat 873

The Bobcat 873 is a G Series skid steer powered by a Deutz BF4M1011F diesel engine, widely used in construction, farming, and landscaping since the late 1990s. Engine reliability directly affects uptime, fuel cost, and jobsite productivity for owners and rental fleets alike.

 

Fab Heavy Parts specializes in aftermarket and remanufactured heavy equipment parts, with particular focus on Bobcat and Deutz support. As outlined in our about us page at Fab Heavy Parts, we focus on high-quality replacement engine components, competitive pricing, and fast shipping. This article covers engine specs, common problems, rebuild versus reman choices, pricing ranges, and what to check before ordering a replacement.

Bobcat 873 Overview and Role of the Deutz Engine

The Bobcat 873 is a vertical-lift machine with an operating weight of 7,135 lbs and a rated operating capacity of 2,300 lbs (tipping load of 4,600 lbs). It features a maximum lift height to the hinge pin of 124.0 inches and a width of 74.0 inches, making it suitable for heavy-duty tasks in confined job sites, similar in capability to other high-capacity loaders like the Bobcat 863 compact loader.

 

The Deutz BF4M1011F engine provides power for both drive and hydraulic systems through the hydrostatic transmission. Typical applications include maintaining and repairing heavy equipment using parts from suppliers like Fab Heavy Parts’ industrial parts catalog:

• Loading dump trucks and pallet fork work
• Site prep and snow removal
• Farm chores with frequent starts and long hours

 

Travel speed runs about 6.9 mph standard, up to roughly 12.5 mph with the optional two-speed setup, which is comparable to other mid-size loaders such as the Bobcat 763 compact loader.

 

Deutz BF4M1011F Engine Specifications for the Bobcat 873

The Bobcat 873 Skid Steer Loader features a Deutz BF4M1011F, 4-cylinder, liquid-cooled, turbo diesel engine with a displacement of 178.3 cu in (2.92 L) and produces 73 hp at 2,300 RPM.

Specification	Value
Configuration	4-cylinder inline
Aspiration	Turbocharged
Displacement	178.3 cu in (2.92 L)
Rated Power	73 HP @ 2,300 RPM
Cooling	Liquid-cooled with oil-cooled components
Fuel System	Mechanical injection
Oil Capacity	16 quarts (crankcase + cooler)
The Deutz BF4M1011F engine is designed for high ambient temperature performance due to its oil-cooled system. The engine features an integrated oil-cooling system that eliminates the need for a traditional cooling radiator in certain configurations. The compact size of Deutz engines provides an advantage in space-constrained applications such as skid steers. The Deutz BF4M1011 engine generally has a higher power-to-weight ratio and efficiency compared to competitor engines, much like the efficient Kubota V1702 used in the Bobcat 743 engine guide.

Common engine identification codes include BF4M1011F, with Bobcat part numbers like 6669745 or reman reference 6686497REM. For older machines, understanding engine tags is also critical on models such as those covered in the Bobcat 743 specifications. Always confirm the exact engine tag before ordering.

 

Common Bobcat 873 Deutz Engine Problems and Symptoms

Even a well-built Deutz engine develops issues after thousands of hours. Problems typically appear beyond 4,000–6,000 operating hours, accelerating in dusty environments or with poor maintenance.

 

Frequent issues include:

• Hard starting or no-start: Often traced to glow plugs, fuel delivery problems, or compression loss. These engines are equipped with an advanced glow plug system, providing enhanced cold-weather starting capabilities. Common cold start issues can often be resolved by using quality replacement glow plugs.
• Excessive smoke: Black indicates rich fuel mixtures or injector problems. Blue signals oil burning. White suggests coolant intrusion via head gasket failure.
• Overheating: Usually caused by clogged radiators, oil coolers, low coolant, or water pump failures under heavy hydraulic loads. Hydraulic pump whine or overheating is often caused by dirty filters or low fluid levels—replace filters using appropriate service kits and quality components like those found in our Kubota and other engine parts selection.
• Oil consumption and leaks: Check rocker covers, crankshaft seals, or worn pistons and rings; severe wear may require following a detailed piston replacement cost and procedure guide.
• Power loss: Sluggish hydraulics when the engine can no longer hold rated RPM, similar to what operators may notice on other loaders such as the Bobcat 753 skid-steer.

 

Weak lift power in Bobcat 873 machines equipped with Deutz engines may be due to worn lift cylinders or leaking seals, which can be addressed by rebuilding with cylinder kits. Deutz engines are sensitive to fuel quality and may experience fuel system issues if not maintained properly.

Repair vs. Reman vs. Complete Drop-In Deutz Engines

When your Bobcat 873 Deutz engine fails, you have three main paths: in-frame repair, full rebuild, or remanufactured drop-in.

 

In-Frame Repair: 

• Includes head gasket, injectors, glow plugs, possibly one cylinder repair
• Makes sense for lower-hour engines with top-end damage only
• Risks overlooking hidden bottom-end wear

 

Full Rebuild: 

• Block machining, new pistons, liners, crankshaft work, bearings, complete gasket sets
• Requires 1-2 weeks of skilled labor and specialized tools
• Good for moderate bottom-end damage when shop access exists

 

Remanufactured Drop-In: 

• Ships assembled and dyno tested, ready for direct installation
• Fastest option—often 1-2 days for experienced shops
• Remanufactured engine options for the Bobcat 873 include the DEUTZ TIER II NEW TURBO engine, which comes with a 12-month warranty

 

Deutz engines typically require more expensive parts and specialized maintenance compared to alternatives like Kubota. For high-hour 873 machines in rental fleets, reman drop-ins reduce guesswork and get you running faster. You can source components through the broader Fab Heavy Parts online parts store. Contact Fab Heavy Parts to find the correct option based on your machine hours and budget.

 

Compatibility, Serial Numbers, and Engine Identification

Ordering the wrong engine is an expensive mistake. Bobcat 873 machines often have serial prefixes like 5099XXX or 5141XXX, just as other models such as the Bobcat S130 skid-steer loader use distinct serial and engine identifiers that must be verified.

 

Where to find serial number plates: 

• Machine: Frame near the rear or inside the cab on the left side
• Engine: Deutz ID plate located on the block or timing cover area

 

Some Bobcat part numbers like 6669745 or reman number 6686497REM cross-reference the same Deutz base engine, and similar cross-referencing applies on machines like the Bobcat S205 skid-steer. Verify superseded numbers when ordering. Fab Heavy Parts can review your serial number and engine tag photos to ensure a correct fit.

 

Maintenance Tips to Extend Deutz Engine Life in a Bobcat 873

Proper routine care can push a Deutz BF4M1011F well beyond typical hour marks:

• Change oil by hours using the correct grade for Deutz engines (typically 15W-40 diesel-rated)
• Replace fuel and air filters on schedule—double frequency in dusty sites, as you would on other compact loaders such as the Bobcat T190 track loader
• Keep cooling system cleaned (radiator and oil cooler fins blown out daily)
• Check valve lash, belts, and hoses at regular intervals
• Proper maintenance of Deutz engines, including periodic timing belt changes, is crucial to prevent significant engine damage, just as regular service is on models like the Bobcat T595 compact track loader
• Use high-quality parts for glow plugs, injectors, and head gaskets, similar to the premium components recommended for machines such as the Bobcat T870 loader

 

Keep service records updated with hours and fluid changes. This helps you figure out when replacement makes sense before catastrophic failure puts your machine out of state.

FAQ

Q1: How many hours can a Bobcat 873 Deutz engine typically run before major work?

A1: Many well-maintained Deutz BF4M1011F engines reach 5,000–8,000 hours before needing major overhaul. With exceptional care, these engines are noted for their durability, often exceeding 12,000 to 15,000 operating hours. Dusty conditions or skipped services shorten this window considerably.

 

Q2: Can I swap a different engine model into my Bobcat 873 instead of the Deutz BF4M1011F? 

A2: Engine swaps to alternatives like Cummins are possible but complex, requiring custom mounts, wiring changes, and cooling system modifications. Staying with a correct-spec Deutz replacement is normally cheaper and more reliable. Write off the swap idea unless you have significant fabrication resources.

 

Q3: What signs tell me I should replace the whole engine instead of just repairing it?

A3: Key signals include low compression across multiple cylinders, metal in the oil, rod knock, cracked block, or a hole from thermal stress. When you see repeated head gasket failures or other factors pointing to bottom-end damage, a remanufactured drop-in often provides better long-term value.

 

Q4: Do I need to program electronics when installing a reman Deutz engine in a Bobcat 873?

A4: No programming is required. The Deutz BF4M1011F is a mechanical diesel without advanced electronic controls. Installation focuses on correct mechanical fit, fuel connections, and basic wiring rather than ECU work.

 

Q5: How long does it take to change a Deutz engine in a Bobcat 873? 

A5: An experienced shop with proper lifting equipment can typically pull and replace a complete engine in 1-2 working days. Rust, accessory condition, and how many components need to be swapped from the original engine affect total time. The rest depends on parts availability. California and other states may have additional requirements for disposal of fluids—be aware that some engine components may contain materials known to the state to cause cancer or reproductive harm.
