The majority of your construction and farm equipment will need to be put to use as spring approaches. Our suggestions below will help you prepare your equipment for the upcoming construction and farming seasons. When your construction or farm equipment needs repair or maintenance services in Corinth, Kentucky, or the surrounding areas, contact Cross Diesel Repair to get the job done. Complete Routine Maintenance If most of your construction equipment has been sitting idle all winter, spring is a great time to get it back up and running. We recommend doing the following maintenance tasks: Change the oil - Both hydraulic and engine oil should be replaced on a regular basis to ensure they are clean and functional. Replace filters - Filters that are dirty or clogged will reduce the effectiveness of your equipment, and additional pollutants can cause failures. Lubricate parts - Any important parts that have not been used for an extended period of time should be greased. If the engine hasn't been used in a while, check the color and consistency of the coolant. Replace the coolant if you notice contaminants or corrosion. Clean the interior and exterior of your equipment - If your equipment has snow or ice crusted on it, carefully remove it using a brush or an air compressor to avoid damaging the paint. Before operating any heavy machinery, wait for the ice around the gearbox or motor to thaw. The cab should also be cleaned and dusted to protect the internal electronics. Do a Final Inspection Check that all vital components are operational before operating any heavy equipment. Even dormant equipment can sustain pest-caused leaks or cable breaks. We recommend that you examine the following elements: Tires Brakes Battery Engine belt Seals, clamps, and hoses Lights and wipers Stickers and decals Construction Equipment Maintenance in Corinth Construction equipment, agricultural vehicles, and other heavy-duty equipment require routine maintenance and occasional repairs, just like any road-going vehicle.

What Our Corinth Mechanics Say About Transmission Rebuilds

By Cross Diesel Repair 07 Mar, 2023

If your semi truck’s transmission is past the point of repairs making a difference, consider getting it rebuilt. To help you make a decision, we've outlined a few of the benefits and drawbacks of transmission rebuilding below. When you need transmission repair or a rebuild in Corinth, Kentucky, or the surrounding areas, contact Cross Diesel Repair to get the job done. How Does a Transmission Rebuild Work? The transmission must be removed and meticulously disassembled before being rebuilt. A skilled mechanic will painstakingly clean each part while also doing a comprehensive inspection of the transmission. Broken and worn-out parts will be replaced. If the technician finds that any design problems have been corrected by the manufacturer, they will modify the transmission in accordance with the manufacturer's recommendations. The Benefits of Rebuilding Rebuilding a transmission typically costs less than buying a brand-new or even remanufactured one. Rebuild prices generally cost between $3,000 and $7,000, depending on the vehicle model. If you choose to have the transmission rebuilt, your semi should continue to operate for at least a few more years. With a rebuild, you will receive a second warranty to cover any potential future repairs in most cases. The Risks of Rebuilding It takes time to complete a rebuild. Due to how time-consuming the process is, you should budget at least two or three days for the task. Remanufactured transmissions require more upkeep than new ones do. Yet you shouldn't worry about future repair costs if your repair is covered by a warranty.

Why Our Corinth Shop Is the Place To Go For Semi Truck Maintenance

By Cross Diesel Repai 07 Feb, 2023

The regular maintenance of semi-trucks should be a top priority for all semi-truck drivers. In addition to significantly extending the life of your truck, maintenance services are crucial for complying with DOT regulations. We discuss a few of the most important maintenance responsibilities below. When you need to schedule semi truck maintenance in Corinth, Kentucky, or the surrounding areas, contact Cross Diesel Repair . Full-Service Oil Change During a full-service oil change, your truck's used, dirty oil is replaced with new oil. If the oil isn't changed frequently enough, contaminants can accumulate in the engine, increasing the danger of overheating and driving up fuel usage. Find out how often your truck needs to have its oil changed by speaking with your local mechanic. Department of Transportation Inspections The Department of Transportation mandates that competent inspectors who have earned the required training or certification review commercial motor vehicles every 12 months. All specified parts of the truck must pass inspection before being cleared to drive. Heavy fines will be given if a vehicle fails a DOT inspection. Tire Checks According to the National Highway Traffic Safety Administration, tires are responsible for one out of every eleven collisions. Before every trip, check to see that yours are in good shape and properly inflated. Underinflated tires struggle to maintain their traction on slick, snow-covered roads throughout the winter. Tire pressure can also increase in hot weather, so use an air pressure gauge to check the levels before you drive. Visit your local mechanic as soon as you discover any signs of tire damage. Semi Truck Maintenance in Corinth Cross Diesel Repair services all years, makes, and models of tractor trailers, both foreign and domestic. Among the most popular trucks we service are Kenworth, Navistar, Peterbilt, Freightliner, Caterpillar, Volvo Trucks, Mack, and International.

Our Corinth Mechanics Discuss the Most Common Problems With Semi Truck Trailers

By Cross Diesel Repair 06 Jan, 2023

No matter what type of semi you drive, trailer maintenance is an essential part of truck care. Below is a list of the most common trailer issues we run into, along with solutions. When your semi needs trailer repair in Corinth, Kentucky, or the surrounding areas, contact Cross Diesel Repair . Structure Damage If your trailer has any interior or structural damage, the goods inside could be at risk. One of the most typical places where trailer damage happens is at truck stops. One way to protect your trailer is to choose the safest parking areas. We recommend parking far away from incoming and outgoing traffic, toward the back of a parking lot. To lessen the possibility that another truck will reverse into or hit the side of your trailer, park next to a fence, light post, or curb. Brake System Failure As part of a normal maintenance check, it's essential to inspect the brakes and wheels of your semi truck. One of the most frequent causes of brake failure is pressure leakage. If parts were made incorrectly or inferior parts were used, new trailers may leak. Leaks can also be caused by corrosion brought on by road surface treatments. As soon as you detect a leak, it's crucial to have your truck inspected. Suspension Issues A trailer's suspension makes sure that its wheels can sustain the weight of the trailer, and any broken suspension parts enhance the likelihood of an accident. Deformities or ruptures in air springs are common suspension issues to be aware of. Air springs can become distorted if improper storage practices were used to handle them. Since overloading the trailer usually results in a burst air spring, it is imperative to know the maximum weight limit for your trailer. Semi Truck Trailer Repair in Corinth Cross Diesel Repair is staffed by ASE-certified diesel mechanics with more than 35 years of combined experience in the servicing of semis, trailers, and other heavy and light-duty trucks.

Construction Equipment Winter Maintenance Tips from Our Corinth Mechanics

By Cross Diesel Repair 05 Dec, 2022

Ice, rain and low temperatures can all harm construction equipment. You can make sure that yours is protected during the winter months by following our suggestions below. When you need maintenance services or repairs for your construction equipment in Corinth, Kentucky, or the surrounding areas, contact Cross Diesel Repair . Keep the Fuel Tank Full Operating machinery in cold weather might make fuel problems worse. Moisture or impurities in the fuel can clog fuel filters and fuel injection devices. Keep the tanks full to avoid condensation in the tank and gasoline lines. Make sure the seal is tight by checking the caps and vents. By including an additional fuel treatment, filters can be defrosted, gasoline can be liquefied, and moisture can be eliminated. Have a spare filter available at all times. Safely Store Unused Equipment One of the easiest ways to keep your construction equipment safe this winter when it's not in use is to store it properly. Maintain your equipment in a climate-controlled storage area to keep it out of the elements. As a bonus, you can avoid the hassle of digging out and cleaning up your equipment when you need it. Top up Fluids Fluids perform worse when it's cold. Seals and joints are affected and friction is increased, as oil thickens and loses viscosity. Oils with a higher viscosity take longer to warm up and flow smoothly. Choose an oil viscosity that is suitable for the surrounding temperature when it is chilly. Your cooling system plays an equally significant role in subfreezing temperatures. Along with preventing corrosion, lubricating shaft seals, and raising boiling point temperatures, it also prevents the engine from freezing. A 50/50 coolant-to-water mix is ideal for most situations. Construction Equipment Repair in Corinth Construction equipment, agricultural vehicles, and other heavy-duty equipment require routine maintenance and occasional repairs, just like any road-going vehicle. When your equipment requires these services, contact Cross Diesel Repair.

What You Need to Know About Semi Truck Brake Repair in Corinth

By Cross Diesel Repair 07 Nov, 2022

An accident involving a semi truck could be disastrous if its brakes fail. As soon as you notice brake trouble, head to your local repair shop. Below is a description of the most common warning signs of impending brake failure. When your semi needs brake repair in Corinth, Kentucky, or the surrounding areas, bring it to Cross Diesel Repair . Excessive Noise When Pressing the Brakes Semi trucks typically need to change their brake pads every 30,000 to 50,000 miles; however, brake maintenance inspections must be carried out more often. When you press worn-out brake pads, you may hear a screaming sound and feel heat. Loud noises coming from the wheel could be a sign that something is wrong with its interior workings. The Brakes Have an Air Leak Your brakes can have air leaks if they seem to be losing power over time. You'll want to be at a shop getting the issue corrected when they finally malfunction, which is typically a gradual process. If there is a pressurized air leak from the wheels and engine compartment, this kind of brake failure may happen. It's necessary to have your semi truck inspected for leaks, especially during the winter when road surface treatments are more likely to cause air leaks. The Brake Pedal Is Soft It is best to apply quick, strong pushes when braking a semi. If the brakes offer little resistance or seem spongey or soft, the engine compartment or the braking system may need to be tuned up. Even if the brake pads are in good condition, this can still occur. Semi Truck Brake Service in Corinth Your truck’s brake system is its most important safety component. We offer complete repair for mechanical truck brakes, electric truck brakes, air brakes, and trailer brakes. If you notice sticking brakes, smoking brakes, soft brakes, or have other issues slowing your truck and trailer, visit Cross Diesel Repair or give us a call at (502) 427-050 . We’ll complete a semi truck brake job that restores the stopping power of your rig.

The Following Signs Indicate Leaking Transmission Fluid, According to Corinth Mechanics

By Cross Diesel Repair 05 Oct, 2022

Unattended transmission fluid leaks can cause serious damage to medium duty trucks. Fortunately, it's easy to identify a leak. The top indications of a transmission fluid leak are listed below. When you suspect transmission leak trouble in Corinth, Kentucky, or the surrounding areas, bring your truck to Cross Diesel Repair . Check the Dipstick If you suspect a transmission fluid leak, check the dipstick first. To accomplish this, take out the dipstick, wipe away the fluid with a rag or paper towel, insert the dipstick once again, and take it out once more. To avoid overfilling the reservoir and risking the fluid overheating, top up the fluid only if it is low. Once a week or so, check the fluid levels to see if they have dramatically decreased. Look for Spots Transmission fluid leaks leave evidence under your truck. Look for dark spots of liquid on the ground where your truck is parked; the color of the liquid will determine its health and can range from a light pink to a dark reddish brown tint. If transmission fluid is not the culprit, you should have the truck inspected for another type of leak. Listen for Strange Noises Noises like grinding or clunking that occur out of nowhere are other indications of low transmission fluid. Fluid is required for transmissions to shift smoothly; low levels cause the gears to grind or clunk. When you hear these noises, take your truck to the shop as soon as you can.
