Keep Your Snow Plow Moving In Winter

Winter is upon us, in full force. With snow and ice on the streets, already, we can expect that December, January, and February will feature more of the same with the potential to halt traffic and even cause horrendous collisions. Equipment operators brave the cold weather and brutal conditions keeping the streets clear, but they need their diesel loaders, snow plows, and spreaders maintained carefully to ensure reliable service no matter what the weather has in store.

Snow removal personnel are up and at ‘em, bright and early, everyday; keeping the streets clear for traffic to pass. If their start is delayed, then the entire city suffers. There is much more at stake than just moving some snow and ice. Lives could be in danger.

The time tested adage says, “An ounce of prevention is worth a pound of cure.” Nowhere is this phrase more thoroughly proven than in the snow removal industry. Cold weather and diesel engines can be a challenging combination, but regular inspections and proper maintenance can give you the edge on the cold and save you dollars in the long run.

In addition to regularly scheduled maintenance, operators can keep their equipment running smoothly by performing daily inspections. A custom tailored and detailed daily inspection checklist for each vehicle is an excellent system for preventing small malfunctions from becoming huge catastrophes. Key points should include:

  • Checking and topping off all fluids.
  • Visual inspection of blades, teeth, hardware, hydraulic lines, and linkages.
  • Visual inspection of braking components, including master cylinder.
  • Check tire air pressure and tread condition, including minimum tread depth.

For all of your regularly scheduled maintenance needs, complete bumper-to-bumper service, as well as state-of-the-art diesel, direct injection, and turbo repair, you can count on Western Turbo, Winnipeg’s premier turbo diesel repair facility.

Tips for Troubleshooting Your Diesel Turbocharger

A faulty or damaged turbocharger can do more than just rob your diesel engine of needed power boost. If left untreated, it can easily lead to total engine failure and very expensive additional engine component damage. So it’s important that you be able to identify any problems in your turbocharger, and their potential causes before they get more serious, and more costly.

Engine Lacks Power

If your engine is lacking in power, there are several possible causes other than your turbocharger. Check first to make certain that there are no airflow issues. Make sure that the air cleaner is clean, replaced regularly per manufacturer recommendations, using OEM replacement parts. Check fuel injectors and fuel pump for adequate flow; make sure ignition timing is set to manufacturer specs. If you suspect the trouble is with the turbocharger, examine the impeller blades for any wear or damage. This is usually indicative of foreign objects getting into the turbo housing.

Turbo Unit Seized

When the turbocharger seizes up, or works sluggishly, a likely cause is poor lubrication or damage to the unit. If the rotor assembly doesn’t rotate freely, it could indicate a high buildup of carbon in the assembly. This could be the result of low oil pressure, dirty or degraded lubricating oil. Check oil for dirt or contaminants, replace per recommended intervals with the appropriate grade lube oil.

Improper Rotor Clearance

Regardless of the make and model of an engine, each turbocharger assembly has very specific tolerances with regard to the clearances for its rotors. Deviations from these clearances will adversely affect engine performance and can be due to defective bearings, or poor or dirty lubricant oil. Check as above for dirty, insufficient or degraded lubricant.

Noisy / Whistling Turbo

When a turbocharger whistles or produces excessive noise, the cause is most often an air or gas leak, or a leak in the EGR cooler. Check for air leaks, broken, missing or worn gaskets, etc. As above, check for proper clearances.
