Removing Oil Pan: Massey 230 Guide

The oil pan in a Massey 230 can be removed by first removing the oil pump, as outlined in paragraph 80 of the MASSEY FERGUSON MF230 Shop Manual. The oil pump is mounted on the front main bearing cap and driven by the crankshaft. After removing the oil pump, the oil pan can be unbolted from the main bearing cap.

Remove the oil pump

To remove the oil pump from a Massey 230, you will need to begin by removing the oil pan. With the oil pan removed, you can then proceed to the next steps, which involve:

• Removing the cylinder block and oil suction pipe from the main bearing cap.
• Unbolting and removing the front main bearing cap with the oil pump attached.
• Checking the rotor clearance with a feeler gauge.
• If the pump rotor or body are worn, scored, or damaged, the pump assembly must be renewed.
• Removing the oil pressure relief valve spring and plunger from the pump body.
• Inspecting the plunger and bore in the pump body for wear or scoring, and renewing if necessary.
• Ensuring that the oil pressure is 345445 psi at high idle speed with the engine at normal operating temperature.
• If the oil pump drive gear was removed, press the gear onto the shaft, with the flat face gear outward, until the face of the gear is flush.
• Reinstalling the pump by reversing the removal procedure and tightening the main bearing cap screws to 150 N.

It is important to follow the steps in the correct order and to refer to the Massey 230 shop manual for further details and diagrams to ensure a safe and successful oil pump removal.

Unbolt the oil pan

To unbolt the oil pan of a Massey 230, first drain the engine oil. Support the tractor under the transmission housing, then remove the front axle and support housing assembly. Support the oil pan, remove the retaining cap screws, and carefully lower the pan from the cylinder block.

The cast-iron oil pan is part of the tractor's frame and serves as an attachment point for the front support. When reinstalling the oil pan, reverse the removal procedure. Ensure the oil pan is securely fastened to the cylinder block with the retaining cap screws.

When removing the oil pan, it is important to support the tractor properly to prevent any accidental tipping or instability. It is also crucial to place the oil pan in a secure location to avoid spills or leaks.

Additionally, when reinstalling the oil pan, it is essential to follow the correct torque specifications for the retaining cap screws to ensure a secure and proper fit.

Remove the cylinder block and oil suction pipe

To remove the cylinder block and oil suction pipe from your Massey 230, follow these steps:

Begin by removing the oil pan. This will grant you access to the oil pump, which is mounted on the front main bearing cap and driven by the crankshaft. With the oil pan removed, you can now access the cylinder block and oil suction pipe.

Next, you will need to unbolt and remove the front main bearing cap with the oil pump attached. Once the bearing cap is removed, you can then unbolt the oil pump from the bearing cap.

At this point, you should be able to lift and remove the cylinder block and oil suction pipe as one unit. Be sure to set them aside in a safe place, as you may need to refer to them later or reinstall them.

It is important to note that this process can be complex and may require additional tools and expertise. Always refer to the service manual for your tractor and consult a qualified mechanic or technician if you are unsure about any steps or procedures.

Check the rotor clearance

To check the rotor clearance, you will need to remove the oil pan, as outlined in paragraph 80 of the Massey Ferguson MF230 Shop Manual. Here is a step-by-step guide:

• Drain the engine oil.
• Support the tractor under the transmission housing.
• Remove the front axle and support housing assembly.
• Support the oil pan.
• Remove the retaining cap screws and lower the pan from the cylinder block.
• Remove the oil pump by first disconnecting the oil delivery pipe from the cylinder block and the oil suction pipe from the main bearing cap.
• Unbolt and remove the front main bearing cap with the oil pump attached.
• Check the rotor clearance with a feeler gauge as shown in Figure 79 of the manual. The clearance should be 0.01-0.06 mm (0.0005-0.0025 inch).
• If the pump rotor or body are worn, scored, or damaged, the pump assembly must be renewed.
• Reinstall the oil pump by reversing the removal procedure.

It is important to follow the instructions in the service manual carefully to ensure the job is done correctly and safely.

Reinstall the oil pump

To reinstall the oil pump on a Massey 230, 235, 240, or 245 tractor, follow these steps:

• Place the tractor on a level surface and engage the parking brake.
• Jack up the front of the tractor and support it with jack stands for stability.
• Locate the oil pump and ensure that the engine is cool to the touch before starting.
• Clean the area around the oil pump to remove any dirt, grease, or debris.
• Reinstall the oil pump by aligning it with the mounting holes and securing it with the appropriate bolts. Torque the bolts to the manufacturer's specifications.
• Reattach any disconnected components, such as hoses, wiring, or brackets, ensuring they are securely fastened.
• Refill the engine with new oil and replace the oil filter.
• Lower the tractor from the jack stands and remove the jack.
• Start the engine and check for any leaks. Ensure that the oil pressure gauge indicates normal operation.

It is important to follow the manufacturer's guidelines and safety precautions when performing any maintenance or repairs. Always refer to a qualified mechanic or the Massey Ferguson repair manual for detailed instructions specific to your tractor model.
