John Deere 7520 Problems

John Deere vehicles are widely sought after all over the world due to their reputation for dependability. Users, however, frequently run into issues due to the nature of the vehicle.

Let’s talk about typical issues with the John Deere 7520, shall we?
The engine on a John Deere 7520 frequently has problems, including failing to start, failing to rotate, knocking, and overheating.

This tractor has transmission problems, including noisy front and rear axles. Possible faults with the steering include a lack of responsiveness when turning, or the steering wheel spinning freely.

The goal of this article is to help you diagnose and repair a few typical issues with your John Deere 7520.

The engine Won’t Start

The 7520, like other John Deere models, frequently experiences issues with starting the engine. If the engine won’t start, you can hear a clicking noise or nothing at all when you turn the key.

Additionally, you may hear the engine crank, but it will not start. Find the source of the issue and address it as quickly as feasible.

Reason 1: Wrong Valve Timing 

The incorrect timing of the valves is the primary cause of this problem. Valve timing adjustment is the process of synchronizing the opening and closing of the valves of an internal combustion engine with the movement of the pistons within the cylinders.

Solution

The timing of the valves must be adjusted. It’s possible to fine-tune the valve timing on your own with just a few simple adjustments:

• First, all of the idler gear needs to be taken off. Find the 2, 3, and 1 on the idler gear.
• Idler gear 1 must now be fastened to the camshaft, followed by idler gear 2.
• The third idler then needs to be linked to the second idler.

Reason 2: Worn Cylinder Bores  

The second most common reason is worn cylinder bores. Combustion chamber gases and fluids are kept out by a cylinder bore seal.

Worn cylinder bores can cause an engine to lose compression, which in turn reduces engine power and makes it difficult, if not impossible, to start.

Solution

Rebuilding the engine from the ground up should fix the problem. The engine needs to be taken apart, the broken parts replaced or repaired, and then put back together.

Engine repair is a complex and scientific process, and fixing a worn cylinder bore requires specific tools and knowledge of the engine.

Reason 3: Starter Turns Bad

If a diesel engine would not turn over, the problem is often with the starter. In order to get your car up and running, you need a reliable starter. To get a vehicle with a faulty starter relay or motor to move, you will need a jumpstart or a tow.

Solution

The starter needs to be inspected first. If fixing the problem is all that’s needed, this video will show you how to do it. 

Reason 4: Damaged Piston Rings

The piston rings could be damaged or worn, preventing the engine from starting. Check for wear and tear and fraying.

Solution

To rectify this problem, the piston rings must be replaced. It is recommended that a technician perform the replacement. If you are competent in the necessary skills, you can handle it independently.
