The Most Common Odes 800 Dominator Problems Owners Face

The Odes 800 Dominator is renowned for its rugged durability and ample hauling power. But even this workhorse machine can run into problems after years of use, especially if regular maintenance is skipped. Here are the most reported issues with the 800 Dominator:

Frequent Engine Problems

Given the stress placed on the 800 Dominator’s engine during tough climbs, hauling heavy loads, and running at high RPMs, it’s no wonder engine problems emerge. Some common engine issues include:

  • Misfiring or backfiring: This sporadic sputtering indicates a problem with the air-fuel mixture getting to the cylinders, often due to clogged fuel injectors, bad spark plugs, or failing sensors.
  • Won’t start: Difficulty starting, especially after the machine has already been running, can point to fouled spark plugs, a bad starter motor, or lack of fuel pressure.
  • Overheating: Common when engine coolant is low or the cooling system is clogged with sediment. Overheating can lead to blown head gaskets.
  • Knocking/tapping: This metal-on-metal noise may signal low oil pressure or pressure, damaged lifters, loose engine mounts, or timing issues.
  • Excessive oil consumption: Burning or leaking too much oil suggests worn piston rings, engine gaskets, or valve guide seals.
  • Lack of power: Insufficient power, especially when climbing hills or hauling loads, indicates worn rings/cylinders, clogged air filter, or problems with sensors.

Starting Problems

Difficulty getting your 800 Dominator to turn over and start is incredibly frustrating. Causes include:

  • Bad battery: If the battery voltage is too low, you’ll hear a slow laboring crank or just a single click when trying to start. Time for a new battery.
  • Starter issues: The electric starter may be failing and drawing insufficient amps to start the engine. This component wears out over time.
  • Blown fuse: Check for a blown fuse in the starter circuit if you hear zero noise when turning the key.
  • Faulty starter relay: The relay that engages the starter motor when turning the key could be malfunctioning. Tap it with a wrench to see if it will temporarily work.
  • Damaged starter: If you hear grinding when engaging the starter, the pinion gear that engages the flywheel may be worn down. Requires starter replacement.

Overheating Problems

Engine overheating is all too common with the 800 Dominator. It could stem from:

  • Insufficient coolant: The most obvious cause – low fluid from a leak or failing to top it off. Always maintain proper coolant level.
  • Damaged radiator: Cracked or bent fins on the radiator prevent proper airflow. The radiator may need replacement.
  • Clogged coolant system: Sediment buildup inside the radiator, hoses, water pump or passages blocks coolant flow. Flush the system.
  • Failing water pump: This vital component circulates coolant. Listen for failing bearing noises or leakage.
  • Thermostat issues: A stuck closed thermostat prevents coolant from flowing into the radiator to shed heat.
  • Fan problems: Electric cooling fans play a key role. Check the fan relay, circuit, and temperature activation.

Jerking, Power Loss & Lack of throttle Response

Intermittent power loss, hesitation and jerking as you accelerate points to:

  • Failing sensors: The crank position, oxygen, throttle position and other sensors must be in top shape to optimize fuel delivery and spark timing.
  • Dirty fuel injectors: Clogged injectors limit fuel delivery under load, causing hesitation and power loss. Run fuel injector cleaner additive.
  • Vacuum leaks: Any air leaks in the intake manifold, vacuum lines, or gaskets upsets the air-fuel ratio under acceleration.
  • Spark plugs: Old spark plugs have difficulty igniting the air-fuel mixture under load. Inspect and replace worn plugs. Use anti-seize on the threads.
  • Fuel pump: As pumps age, fuel pressure and volume output declines. Replace the pump if needed.

Transmission Slipping and Hard Shifts

Transmission issues arise from lack of maintenance:

  • Low fluid: Insufficient transmission fluid will make the clutch packs slip under load. Top off the fluid if low.
  • Contaminated fluid: Particle and metal contamination in dirty fluid can damage internal components. Change the fluid and filter.
  • Worn clutch packs: The high-friction clutch discs that engage the gears wear over time, especially with heavy loads. This allows slipping between shifts.
  • Damaged gears/bearings: Excessively worn or damaged gears can also result in grinding noises and hard shifts. May require transmission rebuild or replacement.
  • Faulty sensors: Sensors like the transmission speed sensor enable smooth shifting. Replace any faulty sensors.

Drive Belt Problems

The 800 Dominator utilizes several vulnerable drive belts that can break or shred over time:

  • Starter belt – Connects the starter motor to the engine crankshaft.
  • CVT belt – Critical continuously variable transmission (CVT) belt that activates the pulleys to shift RPM and speed.
  • Accessory belt – Also called the serpentine belt. Turns accessories like the alternator, water pump and power steering pump.

Inspect all belts for cracking, fraying and proper tension. Replace any worn drive belts immediately to avoid being stranded when they break entirely. Keep spares on hand.

Brake Problems

Braking problems present major safety concerns. Be aware of:

  • Worn brake pads/shoes: Pads and shoes have built-in wear indicators that produce a screeching noise when replacement is needed. Don’t delay replacement.
  • Air in brake lines: Spongy brake pedal feel signifies air bubbles in the brake fluid lines. Bleed the lines to restore firm pedal pressure.
  • Leaking brake fluid: Visually inspect brake components for any dripping fluid and have leak sources repaired asap. Top off the reservoir.
  • Warped brake rotors: Heat buildup causes rotors to warp. Machining or replacing rotors is required to reduce vibration when braking.
  • Contaminated brake fluid: Moisture-contaminated brake fluid boils at lower temperatures, reducing braking performance. Flush the old fluid.

Electrical Gremlins

Like most machines, the Odes 800 Dominator can suffer its share of difficult-to-track-down electrical issues:

  • Corroded contacts/connections: The Odes is used outdoors in all conditions. Inspect electrical connectors for corrosion and clean/repair as needed. Dielectric grease helps.
  • Faulty alternator: If the battery isn’t being recharged properly, suspect problems with the alternator output. Test its charging voltage.
  • Short circuits: Damaged wiring insulation can create shorts and electrical fires. Inspect wiring harness for cracks, burns and bare spots.
  • Blown fuses: When electronics suddenly stop working, check for blown fuses. Replace with the correctly rated fuse.
  • Ignition switch issues: Dirty/corroded ignition switch contacts cause intermittent power problems. Spray contact cleaner into the switch and toggle the key.
  • Bad battery cables: Resistance in damaged positive and negative cables causes slow cranking and electrical issues. Replace worn cables.
  • Faulty electronics: Some Odes accessories are known to fail, like the speedometer display and gauge cluster. Buy OEM replacement parts.

Gas Tank & Fuel Problems

Since the 800 Dominator is fuel injected, it’s less susceptible to carburetor issues. But keep an eye out for:

  • Clogged fuel filter: Restricted fuel filters prevent optimal fuel flow to the fuel pump and injectors. Change filter every 60 hours or annually.
  • Kinked fuel vent tube: The vent tube relieves pressure in the tank. If kinked, air and fuel flow is blocked. Inspect routing.
  • Contaminated/old gas: Stale gasoline or water-contaminated fuel causes combustion issues. Use fuel stabilizer. Drain tank annually.
  • Faulty fuel pump: Listen for whining pump noises. If fuel delivery pressure is weak, the pump may need replacement.
  • Dirty fuel injectors: Clogged injectors disrupt the fine fuel atomization needed for clean combustion. Try running some injector cleaner additive through the system.

Expert Troubleshooting Tips for Odes 800 Dominator Problems

When your 800 Dominator acts up, there’s an art to accurately diagnosing the cause before paying for repairs. Follow these tips from experienced Odes technicians:
