Dozer daily inspection checklist
A dozer’s daily check is half undercarriage. The blade and the ripper do the work you can see, but the tracks, rollers, idlers, and sprockets carry every tonne of it, and they wear whether you watch them or not. The other thing particular to a dozer is what it collects: a machine that pushes brush, scrap, or dry fill all day packs its belly pans and engine bay with material that sits against hot metal.
This list runs in walk order: the blade and frame, then both tracks end to end, then the function checks from the seat. Your operator’s manual is the authority for model-specific items and for any figure you measure against, track sag included. The table after the checklist sets out what each province and US OSHA asks, rule by rule.
Engine off — the walkaround
Blade and ripper down on the ground before you start. Never walk or reach under a raised blade.
- Blade, cutting edges, end bits — cracks in the moldboard and welds, edge and end-bit bolts tight, nothing worn back into the moldboard itself.
- Push arms or C-frame — arms, braces, and trunnions crack-free, pins and caps retained, no fresh play at the trunnions.
- Blade cylinders and hoses — lift, tilt, and angle rods unscored, seals dry, hoses unchafed at the pivots. Look for leaks with your eyes, never your hand.
- Ripper shanks, tips, pins — tips present and not worn into the shank, pins and keepers in place, no cracks in the shank or frame, if fitted.
- Fluids — engine oil, hydraulic oil, coolant, and fuel levels, then a look underneath for anything fresh.
- Radiator and cooler cores — cores and screens clear of dust, chaff, and mud, so air actually moves through them.
- Belly pans and engine bay — no packed fines, leaves, wood chips, or oily rubbish sitting near the exhaust, turbo, or manifold.
- ROPS/FOPS, cab, and steps — structure uncracked and bolts tight, glass whole, steps and grab handles clean and solid.
Undercarriage — both tracks, end to end
Walk each track the full length, engine still off. Clean packed material out first, or you’re inspecting mud.
- Track tension and recoil — sag even side to side and where your manual puts it; recoil and adjuster area undamaged and not leaking grease.
- Sprockets, idlers, rollers — sprocket teeth not hooked or pointed, segment bolts tight; idlers and rollers turning, not leaking, flat-spotted, or loose.
- Shoes, grousers, pins, bushings — no cracked or missing shoes, shoe bolts tight, grousers not worn flat, no pins walking out or links cracked.
- Final drives — seals dry, no oil slung onto the track frame, guards and plugs in place.
- Packed material — mud, rock, and frozen material cleared from around rollers, idlers, and sprockets before it tightens the track.
Engine on — the function checks
- Blade lift, tilt, and angle — full travel each way, smooth, with no drift once the controls are released.
- Ripper raise and lower — full travel, holds where you leave it, if fitted.
- Steering and decelerator — the dozer turns both ways without hesitation; the decelerator brings engine speed down smoothly.
- Service and park brakes — the machine stops when asked and holds with the park brake set.
- Travel alarm, horn, lights — travel alarm sounding in reverse, horn working, work lights and beacon on.
- Gauges and seat belt — no warning lights left on, hour meter noted, belt latching and not frayed.
Around the machine
- Slopes, edges, soft ground — grade and cross-slope you’ll work, edges and spoil piles, soft or thawing ground that won’t carry the machine.
- People on foot — who works near the blade and behind the machine, and how you’ll see them from the seat.
- Overhead hazards — power lines, branches, and anything the ROPS or a raised ripper can reach.
wearpointWhat the rules ask, jurisdiction by jurisdiction
Do this walkaround before every shift. Where a rule below doesn’t name a daily inspection, it often requires the machine to be inspected or used according to the manufacturer’s instructions — so check what your operator’s manual calls for before each shift.
Each row is what one regulation asks of this machine, in plain words, with a link to the text. Where a rule depends on the kind of site or machine, the row says so: check it against your own. This is a summary, not legal advice — the regulation and your operator’s manual govern.
Alberta
Before operating powered mobile equipment, the operator must complete a visual inspection of the equipment and the surrounding area. OHS Code s.257(1)
British Columbia
Before mobile equipment is first operated on a shift, the operator must inspect it and report any unsafe or potentially unsafe defect to the supervisor or employer, then keep monitoring it while it runs. The employer keeps a record of reported defects for at least 2 years. OHSR 16.3(1)–(3)
Ontario
Construction projects: No vehicle or machine may be used while it is defective or hazardous, and it must be used as its manufacturer’s operating manual says. Powered equipment rated over 10 horsepower must be inspected by a competent worker before it is first used at the project, then at least once a year or more often if the manufacturer recommends. Neither section sets a daily inspection. O. Reg. 213/91 ss.93–94
Every workplace: The employer must keep the equipment it provides in good condition, and a worker must report a known defect that may endanger a worker to the employer or supervisor. OHSA ss.25(1)(b), 28(1)(c)
Quebec
Construction sites: Any self-propelled vehicle or equipment driven by a power source other than manual must be checked by an experienced person before its first use on the site, then daily whenever it is used. CSTC s.3.10.1(b)
Elsewhere, such as a yard or plant: A self-propelled vehicle must be inspected and maintained according to the manufacturer’s instructions or standards offering equivalent safety. Section 272 sets no inspection frequency of its own. RSST s.272
Nova Scotia
The employer must ensure powered mobile equipment and forklifts are operated, inspected, serviced, maintained, and repaired according to the manufacturer’s specifications, or specifications certified by an engineer. N.S. Reg. 44/99 s.55
United States (federal OSHA)
Construction sites: OSHA’s earthmoving equipment rules set no inspection interval of their own. 29 CFR 1926.602(a)
Construction sites: The employer’s safety program must provide for frequent and regular inspections of equipment by competent persons it designates. Equipment that doesn’t comply with OSHA’s construction rules may not be used and must be tagged, have its controls locked, or be removed. 29 CFR 1926.20(b)(2)–(3)

Undercarriage: where a dozer’s money goes
Ask any shop where the repair budget on a dozer ends up and they will point at the tracks. Pins, bushings, links, rollers, idlers, and sprockets wear as a system, so a problem in one part spreads to the others. The daily walk is how you catch it while it’s still one part.
Track tension is the first thing to look at. A track run too tight loads every pin, bushing, and sprocket tooth on every turn and eats power doing it. A track run too loose whips, slaps the carrier rollers, and can come off on a side slope. Check sag on the kind of ground the machine is working, after it has been cleaned, and compare one side with the other. Your manual says where it should sit and how to measure it; adjusting it is a job for whoever your shop assigns, not something to improvise with a grease gun on the recoil.
Packed material changes everything. Mud, clay, or frozen spoil packed around the sprockets and rollers tightens the track as surely as the adjuster does, and it hides the cracks and leaks you are looking for. Clean it out with the engine off and the machine parked on level ground, using a bar or shovel from outside the track, never by reaching in between the shoes and the frame. Then look: sprocket teeth turning hooked or pointed, rollers that don’t turn, oil slung onto the track frame from a final drive, a pin walking out of a link.
Uneven wear is information. One track wearing faster than the other, or one side of the rollers worn more than the other, usually comes from how and where the machine works: always turning the same way, or working the same side-hill. Note it, and tell the shop.
Debris and fire
A dozer clearing brush, pushing at a landfill, or working a scrap yard picks up fine material everywhere. It packs into the belly pans and around the engine, the turbo, and the exhaust, mixed with whatever oil the machine has been weeping. That is a fire load sitting on the hottest parts of the machine. Clean out the belly pans and the engine bay as part of the daily check, with the engine off and cool, and check the radiator and cooler cores while you’re there: packed screens cook the engine before they set it alight. Know where the extinguisher is and that it’s charged. And walk past the machine again after you shut it down at the end of the day: smouldering debris often shows up after the engine stops, not before.
When something fails
Take the dozer out of service. Tag it where the next operator will see it, take the key, and report it to your supervisor. Only a qualified mechanic repairs it. The defect that gets noted and run anyway is the one that hurts someone.
How wearpoint runs this checklist
You build the dozer checklist once in wearpoint as an inspection template, in your own words and walk order, and every dozer in that category uses it. Every item takes a verdict: OK, Issue, or N/A. A defect is flagged with a quick note, and open defects carry forward to the next inspection until the fix is recorded, so a roller that stopped turning on Monday is still on the list on Wednesday. The operator raises it as an issue in one tap, the shop triages it into a work order, and the people responsible get an alert when a machine goes down. Operators tap in on the machine and enter the hour-meter reading when they tap out, so service comes due on the hours the dozer actually ran.
