Perhaps they won’t work properly or according to plan. However, let’s discuss some troubleshooting advice before you start beating your head against the computer. The attachment itself should first be inspected for any obvious wear or damage.

Every component can go haywire at times due to a loose bolt or a worn-out component. Should you replace worn parts or tighten loose ends, you could be able to resume your activities.

Look over the hydraulic connections if that doesn’t fix the issue. A leak or a blockage can cause issues. It’s like having a clogged nose—nothing works properly until you clear the path.

On a Bobcat 753 skid steer, several components and attachments require regular maintenance or replacement due to wear and tear to ensure smooth operation. Here’s a breakdown of the parts you mentioned and others that should be monitored:

1. Fuel Tank Hose and Clamp

• Function: The fuel tank pickup screen filters fuel before it enters the fuel lines, protecting the fuel system from debris or contaminants that could clog injectors or damage the engine.
• When to Change: Over time, the screen can become clogged, affecting fuel flow and engine performance. It should be checked periodically and replaced when fuel delivery issues are noticed (e.g., engine sputtering, loss of power).
• Signs of Wear: Clogged or restricted fuel flow, slow startup, or reduced engine performance.
• Maintenance Tip: Check for cracks or leaks in the hoses and replace them when showing signs of wear.

2. Fuel Primer Pump

• Function: The primer pump is used to manually pump fuel into the engine to assist with starting, particularly after fuel system maintenance or when the engine has run out of fuel.
• When to Change: If the primer pump no longer builds pressure or if fuel is not reaching the engine, it may need to be replaced.
• Signs of Wear: Difficulty starting the machine, especially after fuel system servicing, or a lack of pressure build-up when using the pump.
• Maintenance Tip: Inspect the primer pump during routine fuel system checks and replace it when it shows signs of cracking or poor performance.

3. Pin and Bushings

• Function: Pins and bushings are part of the machine’s articulating joints (such as the loader arms) and allow movement while bearing loads.
• When to Change: Over time, due to heavy loads and repetitive motion, pins and bushings wear out, leading to excessive play in the joints, reducing machine precision and control.
• Signs of Wear: Increased play or movement in the loader arms, noisy or squeaky joints, or visible wear on the pin or bushing.
• Maintenance Tip: Regularly lubricate pins and bushings, but replace them when noticeable play or wear is observed.

4. Pressure Oil Engine Switch

• Function: This switch monitors engine oil pressure and alerts the operator to low oil pressure, which can prevent engine damage due to oil starvation.
• When to Change: If the switch malfunctions or the machine’s oil pressure warning light stays on despite normal oil pressure levels, the switch may need to be replaced.
• Signs of Wear: False low oil pressure readings or engine performance issues tied to low oil pressure alerts.
• Maintenance Tip: Replace if inaccurate readings persist after checking oil levels and pressure.

Additional Components to Monitor for Wear and Tear:

1. Radiator Cooling Hose: Regularly inspect for leaks, cracks, or signs of wear.
2. Filters (Air, Oil, and Hydraulic): Regularly change to ensure optimal performance and prevent contaminants from entering sensitive parts.
3. Drive Belt: Check for cracking, fraying, or wear. A worn belt can slip or break, affecting power to auxiliary systems.

Preventive Maintenance Tips for the Bobcat 753

Importance of Regular Maintenance

Routine maintenance for your Bobcat 753 will keep it operating efficiently and avert expensive malfunctions. You’re asking for trouble if you ignore maintenance. I promise that the Bobcat 753, when neglected like a houseplant, will not like it. Thus, do yourself a favor and adhere to a schedule for routine maintenance.

I think it’s best for each of us to have a manual when servicing a piece of machinery. Here’s a link to a Bobcat 753 Workshop Repair Manual in case you want to have a go at replacing some parts yourself.

Avoid Overheating

Coolant and Thermostat

Don’t forget to check the temperature in the system. Keep an eye out for any irregularities. If you spot any concerns for overheating, first check the coolant level, then check if the thermostat needs changing.

Oftentimes, the problem is from the thermostat, because it can’t gauge the temperature correctly so the system can’t maintain it with whatever it has for the purpose. So yeah… cooolan and thermostat. Quick cheap fixes before it gets down to anything serious causing an overheating in the Bobcat 753.

Hydraulic Oil Cooler

How the Hydraulic Oil Cooler Grill Works:

1. Heat Dissipation: The hydraulic system in the Bobcat 753 generates heat as it operates. The oil cooler grill allows airflow to pass through and cool down the hydraulic oil, ensuring that it stays within safe operating temperatures.
2. Position: The cooler is typically located at the rear of the machine, in front of the cooling fan and radiator. The grill helps protect the cooler from debris while still allowing airflow.
3. Cooling Fan: A fan draws cool air through the grill and over the cooler’s fins, transferring heat from the hydraulic oil to the air.

Signs the Oil Cooler Grill Needs Changing or Cleaning:

1. Overheating Issues: If the Bobcat starts to overheat or the hydraulic fluid temperature gauge shows a high reading, it could indicate that the oil cooler grill is clogged with debris or isn’t allowing proper airflow.
2. Physical Inspection: Check the grill for signs of blockages (e.g., dirt, mud, leaves) or physical damage (like bent fins or cracks). If debris is preventing airflow or the grill is damaged, it needs cleaning or replacement.
3. Restricted Hydraulic Performance: If the machine feels sluggish or less responsive, this might indicate hydraulic overheating, often related to a blocked or inefficient oil cooler.
4. Fan Running Constantly: If the cooling fan is running more than usual, this might indicate the system is struggling to keep temperatures down, likely due to a dirty or damaged cooler grill.

Maintenance:

• Cleaning: Regularly cleaning the oil cooler grill is essential. Use compressed air or a low-pressure water hose to remove debris. Be careful not to bend the fins while cleaning.
• Replacement: If the grill is damaged or severely clogged beyond cleaning, it should be replaced to ensure proper cooling.
