Motor graders are widely popular construction machines globally, and a used motor grader can be a cost-effective option for many contractors and fleets. While highly cost-effective, buying a good and a bad used grader often comes down to one factor: how much money you will spend in the first 500 hours. Hidden problems like worn circle gears, sloppy hydraulics and damaged undercarriage hardly show up when you check machine hours and photos.
Many buyers are fooled by a grader that looks great on the outside, but has a handful of undiscovered flaws inside and UAE-specific wear patterns, which often come with a triad of extreme heat, fine sand and long-hour usage. Once you ignore these factors and buy a used motor grader machine with underlying issues, your investment quickly turns into a nightmare.
So, how do you pick a good used grader equipment? Well, to know this, you must first understand why UAE buyers need a different checklist and the factors you must know before settling for a machine.
Used Motor Grader Inspection Checklist
- Heat above 45° in UAE conditions breaks down hydraulic fluids faster than in colder climates
- Fine sand and gravel enters components, ceals, bearings and gear teeth to wear them faster over time
- Continuous stop-start roadworks results in faster wear in brakes and clutches
- Many machines are re-exported after local use and service records are often missing
- Import document gaps causes delays in registration and resale later
Used Motor Grader Inspection Checklist
Before you settle for a used motor grader, go through this motor grader inspection checklist to know if it's worth the money you’re spending or if the machine as a whole deserves your attention. This will help you negotiate or avoid buying a problematic machine:
1. Engine & Fluids
Once you visit the machine in person, start the engine when it's cold and look for knocking sounds or excessive smoke after it starts. Check the colour of the oil and smell for a burning odour. This is often caused by overheating due to high UAE ambient temperatures. Look under the dozer for fresh leaks around parts like the turbo, gaskets, and coolant lines, because sand buildup can often hide older stains.
2. Circle & Moldboard
The circle and moldboard are among the most critical parts of a bulldozer and take the main beating during grading work. That said, check for play when you rotate the circle by hand. If you find excessive movement that can be due to worn gear teeth, which is costly to replace. Assess the condition of the moldboard leading edge, looking for uneven wear, cracks and previous weld repairs. All these indicates to heavy abuse.
3. Hydraulic System
Use every hydraulic function, including the tilt of the blade, circle rotation and articulation. Watch out for jerky and slow movements. Check the cylinder rods for pitting or scoring, because sand contamination usually causes rod scratches over time. Hose condition matters as much, since UAE heat turns rubber brittle faster than cooler climates. Check the hydraulic pump for an odd whining noise after you put the machine under load. A hydraulic pump is costly to replace.
4. Frame & Articulation
Perform an all-round check around the main frame and articulation joint. Look for hairline cracks, especially near pivot points and welds. Mismatched paint or fresh welding in these areas often indicates structural damage.
A motor grader with frame issues is always a bad purchase, as it can cause sudden breakdowns, put safety into question, halt your operations and can never grade a straight line consistently. Additionally, run the machine and steer it left and right. Watch the articulation joint for lags and excessive play. Dust of the UAE builds up in these joints and erodes the bearings if you ignore them.
5. Tyres & Undercarriage
The tyres & undercarriage of your used motor grader play an important role in performance, safety and uptime. Check the tread of the tyres and their wear patterns. Uneven wear can happen due to alignment issues, which can also affect grading accuracy. Check for cracking in the side walls, which are common in used construction machinery due to longer exposure to the sun.
On undercarriage components, check for grease buildup, which is often mixed with sand and often hides worn bushings under them. Tandem housings should be bone dry. Any oil seeping from the tandem covers can indicate damaged seals, which you need to replace immediately.
6. Cab & Controls
Its very important for any used dozer buyer to check the comfort and control functionality to ensure the operator can work efficiently. Before you invest in a specific dozer, get inside the cab, assess the operator seat and test every gauge, joystick and pedal. Ensure they are smooth and don’t feel clunky. A worn seat with low-hour meter is a red flag and indicates that the hour meter may have been tampered with.
Confirm that the ROPS and FOPS structure is not damaged and is intact, because this structure protects the operator during an accident. Additionally, you must also check the AC to make sure it cools properly during the UAE’s unforgiving summers.
7. Hour Meter Vs. Records
Hour meters are a great way to judge the usage of a used dozer, but never trust just the hour meter alone, since it can be reset, tampered with, and replaced. Ask for the maintenance logs, service invoices, and telematics data if the machine has them. If the seller fails to produce these basic records for a machine with “low hours”, this is a big red flag, and you must always avoid such deals.
A machine with heavy moldboard wear and low hours is often a good indicator of tampering. A used Caterpillar 140h motor grader with proper maintenance paperwork and detailed service records is often a better choice than a 3000-hour machine with missing records.
Where To Buy Used Motor Graders: Dealers Vs. Auctions
When you’re looking for a used Caterpillar 140h motor grader, there are several options, among which auctions and used construction equipment dealers often gets the most buyer attention. Buying from an established dealer like Hexco is often a better option if you want transparency and transparency.
Sometimes auctions offer lower prices, but you have a lower chance of getting an “as-is” machine. Popular dealers like Hexco offer various options when buying used dozers, offering detailed paperwork and quality machines. If you can spend a little more, dealers are the best choice, trusted by numerous contractors for sourcing used construction equipment in the UAE.
Are you looking for reliable used bulldozers? Check out Hexco Global, which happens to be the UAE’s leading supplier of used construction equipment. Their expansive lineup of used motor graders includes machines from Caterpillar, including the highly popular Caterpillar 140h motor grader. Contact us today for more information and purchases.
