A motor grader is the only machine on the project whose product is measured in millimetres — and accuracy is exactly what wears away quietly. A rounded edge, a circle with backlash, a sloppy drawbar ball: none of them stops the machine, all of them stop the grade, and the bill arrives as rework at a layer's price. This checklist covers both halves — the accuracy chain and the machine under it — in ten minutes, critical items marked. Run it on paper, or in HVI where fails carry photos and hold the machine — sign up free and put it on your operators' phones this week.
Motor Grader Inspection Checklist — Blade, Circle Drive & Engine
Daily checks for the machine that sells accuracy — the edge-to-tandem precision chain, the hydraulics and engine underneath it, and the safety items a thirty-foot machine owes everyone around it.
The Accuracy Chain — Where Play Adds Up
Cutting edge and end bits — wear against the discard limit, bolts tight, no waves or scallops along the edge. A rounded edge doesn't cut, it rides — and the operator compensates with passes that cost fuel and time.
Moldboard and slide rails — sideshift rails greased and unworn, moldboard free of cracks at the mounting points, tilt mechanism holding position under light load.
Circle and circle drive — teeth checked for wear and packing debris, backlash felt for growth against last week, slip clutch and wear guides seated. Growing backlash here is the classic source of a wandering blade.
Drawbar ball and A-frame — play at the ball checked with the blade grounded lightly, A-frame welds scanned for cracks and fresh rust lines. Play here multiplies through everything downstream.
Tandems, wheel lean and articulation — tandem oil at level with no leak trails, chains quiet at slow travel, wheel-lean linkage greased and free, articulation pins tight. The chain ends where the machine meets the ground.
Each link's small play is invisible alone; together they arrive at the edge as the surface that will not hold grade. Checking the chain daily keeps each link's play known, logged, and scheduled — instead of discovered by the survey crew.
One Machine, Three Kinds of Critical
Fails That Stop the Grade
Edge past discard, circle backlash beyond normal, drawbar play, tilt not holding — the machine still runs, so paper systems let it work while every pass builds rework. These log as defects with photos and go to the workshop's precision queue.
Fails That Stop the Machine
Hydraulic leaks reaching ground, tandem oil trails, blinded radiator cores, choked filters — the breakdowns-in-waiting that daily eyes catch at clamp-and-hose prices instead of tow-and-strip prices.
Fails That Hold It Where It Stands
Brake or steering doubt, articulation lock missing, horn or lights dead on a live carriageway, ripper hoses damaged — a thirty-foot machine working beside traffic and survey crews holds until these clear.
Load the Full Checklist Into HVI in Minutes
This structure comes from the template library and tunes to your models in the no-code editor — your edge discard limits, your tandem oil spec, Hindi or English, photos mandatory on the accuracy chain. Critical fails hold the machine and alert the workshop instantly. Bring your current form to a 30-minute session and our India team rebuilds it live.
The Machine Under the Instrument
Frequently Asked Questions
How do we know when the cutting edge is actually done?
By the OEM's discard dimension, not by feel — measure at the worst point, and change before the moldboard itself starts wearing, because edges are consumables and moldboards are capital. Daily photos in HVI make the wear trend visible, so replacement gets planned into a non-grading window instead of stopping a paving morning.
Who adjusts circle backlash — the operator?
The operator detects, the mechanic adjusts — the daily check is feel and observation logged with a note, and shimming or wear-guide work is a scheduled workshop job. The split keeps the daily list fast and the adjustment correct.
Do the six tyre pressures really affect grading?
Directly — the blade's height is referenced through the tyres, so a soft front or mismatched pair tilts the cut, and the operator ends up chasing a level the machine cannot hold. Pressures per position are an accuracy item as much as a cost item.
Night grading under lights — anything extra?
The same route with deliberate torch checks on the accuracy chain, all work lights proven before the shift, and reflective visibility items verified — night is when a thirty-foot machine and a live carriageway need every lamp working; sign up free and toggle a night-shift variant of the checklist in minutes.
Does the library cover the rest of the road fleet?
Yes — pavers, rollers, excavators, loaders, tippers, and DG sets in the same plain-language, critical-items-marked format, each editable per site and model. See the full library in a 30-minute demo with our India team.
Protect the Millimetres. The Machine Will Follow.
Every level that won't close traces back through the chain — an edge past its limit, a circle with play, a tandem run low — and every one of them was visible on a morning walk before it was measurable in the survey. Run this checklist daily and the chain stays known; run it in HVI and it stays photographed, logged, and fixed on schedule. Start free and put it on your operators' phones this week, or bring your current form to a 30-minute session and leave with it rebuilt.
