Why Bobcat Compact Skid Steer Loader Experiencing Engine Starting Issues?

Is your Bobcat compact skid steer loader struggling with engine starting issues, preventing it from turning over or causing it to crank slowly during material handling, landscaping, or construction tasks on small job sites, farms, or rental projects? Engine starting problems are a critical concern for operators of these versatile machines, as they can lead to significant downtime and disrupt productivity, but they can be resolved with the right knowledge and action. In this blog post, we’ll answer the question: "Why is my Bobcat compact skid steer loader experiencing engine starting issues, and how can I fix it?" We’ll explore the causes, provide detailed solutions, and offer preventive strategies to keep your skid steer loader starting reliably.

Why Is My Bobcat Compact Skid Steer Loader Experiencing Engine Starting Issues?

Engine starting issues in Bobcat compact skid steer loaders can stem from various factors, including electrical problems, fuel system issues, or mechanical wear. Here’s a comprehensive breakdown of the most common causes:

1. Weak or Dead Battery

The battery provides the electrical power needed to crank the engine. A weak, dead, or improperly charged battery can fail to deliver sufficient voltage, preventing the engine from starting or causing slow cranking.

Why it happens: Frequent short uses, leaving accessories on when the engine is off, or an aging battery can lead to a drained or degraded battery.

2. Faulty Starter Motor or Solenoid

The starter motor engages the engine to start it, and the solenoid ensures power is delivered to the motor. A worn or faulty starter motor or solenoid can result in a failure to crank or a clicking noise when attempting to start.

Signs: Clicking sound when turning the key, the engine not turning over, or intermittent starting issues.

3. Fuel System Problems

Issues in the fuel system, such as clogged fuel filters, air in the fuel lines, or a failing fuel pump, can prevent the engine from getting the fuel it needs to start.

Indicators: Engine cranks but doesn’t start, sputtering during startup attempts, or the need to prime the fuel system frequently.

4. Faulty Glow Plugs (For Diesel Engines)

Bobcat skid steer loaders with diesel engines use glow plugs to heat the combustion chamber for easier starting in cold conditions. Faulty glow plugs or a malfunctioning glow plug relay can make starting difficult, especially in low temperatures.

Symptoms: Engine cranks but doesn’t start in cold weather, excessive white smoke during startup attempts, or a glow plug warning light on the dashboard.

5. Dirty or Faulty Ignition Switch or Wiring

The ignition switch sends the start signal to the starter motor. A dirty, worn, or faulty switch, or damaged wiring in the starting circuit, can prevent the engine from receiving the signal to start.

Symptoms: No response when turning the key, intermittent starting, or dashboard lights not illuminating properly.

How Can I Fix Engine Starting Issues in My Bobcat Compact Skid Steer Loader?

Addressing engine starting issues requires a systematic approach. Here are step-by-step solutions to get your Bobcat compact skid steer loader starting reliably again:

1. Test and Charge or Replace the Battery

Check the battery’s voltage and condition using a multimeter. Charge or replace the battery if it’s weak or unable to hold a charge.

Repair steps:

  • Turn off the skid steer loader and use a multimeter to measure the battery voltage (a fully charged battery should read around 12.6 volts).
  • If the voltage is below 12.4 volts, charge the battery using a compatible charger until it reaches full capacity.
  • If the battery won’t hold a charge or is older than 3-5 years, replace it with a genuine Bobcat-approved battery.
  • Test the starter by attempting to start the engine, ensuring it cranks smoothly without hesitation.

Tip: Clean the battery terminals with a wire brush and apply dielectric grease to prevent corrosion.

2. Inspect and Replace the Starter Motor or Solenoid

Test the starter motor and solenoid for proper operation. Replace them with genuine Bobcat parts if they’re faulty.

Repair steps:

  • Disconnect the battery to ensure safety, then locate the starter motor (typically near the bottom of the engine).
  • Test the starter by connecting a jumper cable directly from the battery to the starter terminal (with proper safety precautions); if it doesn’t engage, the starter or solenoid may be faulty.
  • Remove the old starter or solenoid by disconnecting its wiring and mounting bolts, then install a new genuine Bobcat part.
  • Reconnect the battery and test the engine for reliable starting, ensuring no clicking or sluggish cranking.

Tip: If you hear a clicking sound but the starter doesn’t turn, the solenoid is often the issue—replace it separately if possible.

3. Check and Address Fuel System Problems

Inspect the fuel system for clogs, air leaks, or pump issues. Replace filters, bleed the system, or repair the fuel pump to ensure proper fuel delivery.

Repair steps:

  • Check the fuel filters (primary and secondary) for clogs and replace them with genuine Bobcat filters if necessary.
  • Inspect the fuel lines for air leaks (look for bubbles when priming); tighten connections or replace damaged lines.
  • Test the fuel pump pressure using a gauge (consult your Bobcat manual for the correct pressure range); if low, replace the pump with a genuine Bobcat part.
  • Bleed the fuel system to remove air by operating the manual primer pump (if equipped), then test the engine for starting and smooth idling.

Tip: Use high-quality diesel fuel and add a fuel additive to prevent microbial growth, especially in humid conditions.

4. Test and Replace Faulty Glow Plugs (For Diesel Engines)

If your Bobcat skid steer loader has a diesel engine, test the glow plugs and glow plug relay for proper operation. Replace any faulty components to improve cold-weather starting.

Repair steps:

  • Use a multimeter to test the glow plugs for continuity (each should have a low resistance, typically 0.5-2 ohms); replace any that fail the test with genuine Bobcat glow plugs.
  • Test the glow plug relay by checking for power output to the glow plugs when the key is in the preheat position; replace the relay if it’s not functioning.
  • After replacing faulty components, preheat the engine for the recommended time (usually 5-10 seconds), then attempt to start and check for reduced smoke and smooth starting.
  • Monitor the glow plug system in cold weather to ensure consistent performance.

5. Clean or Replace the Ignition Switch and Wiring

Inspect the ignition switch and wiring for dirt, wear, or damage. Clean the switch or replace it and any faulty wiring to restore starting functionality.

Repair steps:

  • Disconnect the battery for safety, then locate the ignition switch (typically on the dashboard).
  • Clean the switch contacts with electrical contact cleaner to remove dirt or corrosion, then test for proper operation.
  • Use a multimeter to test the switch for continuity in the “start” position; if there’s no continuity, replace the switch with a genuine Bobcat part.
  • Inspect the wiring from the switch to the starter for damage or loose connections, repair or replace as needed, then test the engine for reliable starting.

How Can You Prevent Future Engine Starting Issues in Your Bobcat Compact Skid Steer Loader?

Preventing engine starting issues is crucial for maintaining productivity and reliability on small job sites, farms, or rental projects. Here are long-term strategies to protect your equipment:

  • Regular Maintenance: Follow recommended service intervals for checking the battery, starter, fuel system, and glow plugs (if applicable) every 200-400 hours or quarterly, as outlined in manuals for Bobcat compact skid steer loaders.
  • Use Quality Parts and Fuel: Always use genuine Bobcat batteries, starters, glow plugs, and filters, and ensure fuel is clean and free of contaminants.
  • Train Operators: Educate your team on proper starting procedures, such as using the glow plug preheat cycle in cold weather and turning off accessories before shutting down the engine.
  • Protect from Environment: Store the skid steer loader in a sheltered area to minimize exposure to extreme weather, and clean the machine regularly to prevent dirt buildup in the fuel and electrical systems.

By staying proactive, you can extend the life of your Bobcat compact skid steer loader’s engine and ensure reliable starts every time.
