Road construction equipment maintenance: complete maintenance checklist

Downtime of a single unit of equipment on-site means missed deadlines across the entire work front, contract penalties, and a stressed foreman. At the same time, up to 80% of unscheduled breakdowns of road construction equipment are related not to component wear, but to basic missed maintenance: untimely oil changes, clogged filters, or neglect of hydraulics. Below is a working maintenance (TO) checklist that keeps backhoe loaders, rollers, motor graders, and wheel loaders in service all season.

Why maintenance is calculated in engine hours, not kilometers

The key difference between special machinery and a car is that component life is consumed under load, not just in motion. A loader might travel only a few kilometers in a shift but work for 9 hours at maximum torque. Therefore, service intervals are tied to engine hours — they are shown by the counter on the instrument panel. Follow the manufacturer's regulations, but the general logic is as follows:

• Daily maintenance (shift maintenance) — every shift, before starting;
• Maintenance-1 — as a rule, every 250 engine hours;
• Maintenance-2 — every 500 engine hours;
• TO-3 / advanced maintenance — every 1000–2000 engine hours;
• seasonal maintenance — when transitioning to winter and summer.

Exact intervals depend on the model and operating conditions — dust, temperature, and soil type reduce them by 20–30%. The regulations for a specific piece of equipment can be clarified with the manager.

Daily shift checklist (DM): 10 minutes before startup

This is the minimum that the operator does themselves before starting work. A walk-around inspection saves tens of thousands of tenge on repairs.

Fluid levels and leaks

• Engine oil level via dipstick (only on a level surface, with a cold engine);
• Coolant level in the expansion tank;
• Working fluid level in the hydraulic tank;
• Inspection under the machine — checking for fresh oil, antifreeze, or fuel stains.

Visual inspection

• Condition of high-pressure hydraulic hoses — abrasions, bulges, leaks at connection points;
• Integrity of the bucket, blade, ripper, and cutting edges;
• Belt tension and integrity;
• Tire pressure or track tension;
• Operation of instruments, light signals, and reverse alarm.

Separately — draining condensate from the fuel filter-separator. Under temperature fluctuation conditions, water forms in the tank every night, and it is what destroys expensive fuel equipment.

Service-1 (approx. 250 engine hours): consumables

The first scheduled maintenance primarily involves replacing components that get clogged and lose their properties.

• Engine oil and oil filter replacement — the heart of the maintenance schedule, cannot be skipped;
• Checking and blowing out (or replacing) the air filter — in the dusty conditions of Kazakhstan, this is a critical component;
• Replacement of fine and coarse fuel filters;
• Lubrication of all points according to the lubrication chart — pins, bushings, boom joints, slewing ring. An under-lubricated pin wears out in a week and leads to expensive repairs;
• Checking oil levels in axles and gearboxes;
• Tightening loose bolted connections.

TO-2 (about 500 engine hours): units

A deeper revision is added to the TO-1 maintenance works:

• Replacing the hydraulic filter and checking the condition of the working fluid (darkening, burnt smell, emulsion — a signal of a problem);
• Inspection and adjustment of the braking system;
• Diagnostics of the battery, terminals, and wiring condition;
• Checking play in steering and attachments;
• Control of the undercarriage condition: wear of track shoes, rollers, sprockets — or hubs and kingpins on wheeled equipment;
• Reading Error Codes from the On-Board Computer, if Available.

Seasonal maintenance: winter and summer

Sharp continental climate is a specific load on equipment. Before winter, it is mandatory to:

• Transition to winter diesel fuel and winter engine oil with the required viscosity;
• Checking Antifreeze Concentration (Protection Down to at Least −40°C);
• Checking the operation of the pre-heater and glow plugs;
• Charging or insulating the battery — in the cold, it loses up to half of its capacity.

Before summer — cleaning radiators from fluff and dust, checking the cooling system, monitoring the cabin air conditioner condition. Overheating in summer is as dangerous as not warming up in winter.

How to keep maintenance records so as not to lose anything

Oral control does not work for a fleet of several units. Start a record for each machine logbook (or table) with current engine hours and maintenance dates. Record: what was replaced, what consumables were used, who performed the work. This provides three benefits: you don't miss intervals, you see 'thirsty' units in advance, and you maintain the warranty—the manufacturer has the right to refuse warranty repair if there is no confirmation of scheduled maintenance.

A specific tip for procurement officers: keep a minimum stock of consumables in the warehouse — oil, fuel, and air filters, as well as working fluids for your models. Waiting a couple of days for a filter in the peak of the season costs dozens of times more than the filter itself.

In short: what to do today

Implement three things, and most unscheduled downtime will disappear: per-shift inspection by the operator using a checklist, linking maintenance to the hour meter rather than 'by eye', and a service log for each unit. This is discipline, not an expense — and it converts directly into volumes completed on time.
