Key Components and Their Functions

The John Deere 70, like any skid steer, is made up of several key components that work together to get the job done. Here’s a quick rundown to get you familiar with the key parts.

• Engine: The heart of the machine, providing the power to move, lift, and operate attachments. It's usually a diesel engine, known for its fuel efficiency and long life. Regular maintenance here is key.
• Hydraulic System: This system uses pressurized fluid to power the loader arms, bucket, and other attachments. It's what gives the skid steer its strength and versatility. Leaks and contamination are common issues here.
• Undercarriage: This includes the tracks (if it's a track loader) or tires, along with the axles and associated components. It's what allows the machine to move and maneuver. Wear and tear on these parts is inevitable.
• Controls and Operator Station: This includes the levers, pedals, and gauges that the operator uses to control the machine. Keeping these in good working order ensures operator safety and productivity.

Understanding these components is the first step in successful John Deere 70 skid steer maintenance and repair. Now, let’s move onto the fun part: finding those vital parts!

Finding John Deere 70 Skid Steer Parts

Okay, so your John Deere 70 needs a part. Where do you start? Finding the right parts can seem daunting, but it doesn't have to be. Here’s a breakdown of the best places to find what you need, along with tips to make the process easier.

Online Parts Dealers

Online parts dealers are a great first stop. They offer a massive selection of parts, often at competitive prices. Plus, you can shop from the comfort of your own home – awesome, right? Some of the best online sources include:

• OEM (Original Equipment Manufacturer) Dealers: These are your go-to source for genuine John Deere parts. They might be a bit pricier, but you’re guaranteed to get the right part with the best quality. Look for the online stores associated with your local John Deere dealerships.
• Aftermarket Parts Suppliers: These suppliers offer parts that are compatible with the John Deere 70 but aren't made by John Deere. They are often more budget-friendly. Be sure to check reviews and ensure the supplier is reputable before purchasing. Check out their offerings; they can save you some money.
• Specialty Websites: Some websites specialize in skid steer parts. They have a deep inventory and often offer expert advice. They can become really valuable resources. These can sometimes offer the best of both worlds – quality and value. Keep in mind that some parts may need to be ordered specially.

Local Dealerships

Local John Deere dealerships are invaluable, especially if you need advice or immediate assistance. They usually have a knowledgeable staff who can help you identify the correct part and provide installation guidance. Plus, they can often get parts quickly, which minimizes downtime. Building a relationship with your local dealer is a smart move for any John Deere 70 skid steer owner!

Used Parts

If you're on a tight budget, consider used parts. Salvage yards and online marketplaces like eBay can be great sources for used components. Always check the part's condition before purchasing. Make sure to assess them as thoroughly as possible. While used parts can save money, remember that they may have a shorter lifespan than new ones.

Identifying the Correct Part

Before you start shopping, you’ll need to identify the exact part you need. Here's how to do it:

• Consult Your Manual: Your owner’s manual is your best friend! It contains a parts list with diagrams and part numbers. Having the right part number is a game changer.
• Use the Serial Number: The serial number is crucial for finding the correct parts, especially if there were different versions of the John Deere 70 skid steer. The serial number helps to match the parts.
• Inspect the Old Part: If possible, remove the old part and examine it. Sometimes, there are markings or part numbers on the part itself.
• Take Photos: Taking pictures of the part and its location can be helpful when communicating with suppliers or dealerships.

Armed with the correct part number and a little research, you'll be able to find the right parts and get your machine back in action.

Common John Deere 70 Skid Steer Repairs

Even the toughest machines need repairs eventually. Here are some of the most common issues you might encounter with your John Deere 70, along with some troubleshooting tips. This section will guide you through some basic repairs, but always consult a professional if you're not comfortable working on heavy machinery.

Engine Problems

Engine issues are among the most frustrating problems. Here are some common symptoms and potential solutions:

• Hard Starting: This could be due to a weak battery, faulty starter, or fuel issues. Check your battery connections, test the starter, and make sure fuel is reaching the engine. The fuel pump might also be faulty.
• Loss of Power: This could be caused by a clogged fuel filter, air filter, or problems with the fuel injection system. Replace filters regularly and inspect for leaks.
• Excessive Smoke: Black smoke indicates too much fuel. White smoke often indicates coolant leaking into the combustion chamber. Blue smoke means the engine is burning oil. Diagnose and address these promptly.

Hydraulic System Issues

The hydraulic system is essential for operating the loader arms and attachments. Common problems include:

• Leaks: Leaks can occur at hoses, fittings, and cylinders. Check for visible leaks and tighten connections or replace worn hoses. Leaks can indicate worn seals and need immediate attention.
• Slow Operation: This can be caused by a low hydraulic fluid level, a clogged filter, or a faulty pump. Check the fluid level, replace the filter, and inspect the pump for any damage.
• Loss of Lift Power: This might be due to a faulty cylinder, worn seals, or a problem with the hydraulic pump. Inspect cylinders for leaks, replace seals, or consult a mechanic.

Undercarriage Problems

The undercarriage takes a beating, so problems are inevitable.

• Track/Tire Wear: Tracks and tires wear out over time. Regularly inspect the tracks or tires for wear and replace them as needed. Improper track tension can accelerate wear.
• Track/Tire Damage: Rocks, debris, and harsh terrain can damage tracks or tires. Inspect regularly and repair or replace any damage immediately.
• Uneven Wear: Uneven wear can indicate alignment issues or worn components. Have your undercarriage professionally inspected.

Electrical System Issues

Electrical problems can be difficult to diagnose. Common problems include:

• Non-Functioning Lights: Check bulbs, fuses, and wiring for damage or corrosion. Replacing the fuse is the easiest solution.
• Starting Problems: Could be due to a bad solenoid, faulty ignition switch, or wiring issues. Check your fuses and wiring. Inspecting the solenoid is also important.
• Instrument Panel Malfunctions: Check connections and wiring for corrosion. These can also be a simple and often overlooked issue.

These are just some of the most common repairs. Always consult your service manual and follow safety precautions when working on your John Deere 70 skid steer.
