- the assembly of the engine oil pan from the tractor engine.
- the isolating screws (8) and (9) from the engine oil pan (7).
- the joint (4) from the engine oil pan (7). Discard the joint.


If necessary, follow Steps to remove the isolating frame from the cylinder block. Support the isolating frame (12). Use Tooling to remove the torx screws (11) and (13).
- the isolating frame (12) from the cylinder block.
- the joint (10). Discard the joint.

Installation Procedure


Install Tooling to positions (X) in the cylinder block. If necessary, follow Steps to install the isolating frame. Ensure that the joint face of the cylinder block is clean and free from damage. Ensure that the isolating frame is clean and free from damage. If necessary, replace the isolating frame.


Apply a bead of Tooling to positions (Y).


Position a new joint (10) onto the isolating frame (12). Align the isolating frame (10) with Tooling. Install:
- the isolating frame to the cylinder block. Use Tooling to install the two torx screws (11) and the four torx screws (13) to the isolating frame. Tighten the torx screws (11) to a torque of 22 N·m (16 lb ft). Tighten the torx screws (13) to a torque of 22 N·m (16 lb ft).


Ensure that the engine oil pan (7) is clean and free from damage. Clean the isolating screws (8) and (9). Inspect the isolating screws for deterioration or damage. If necessary, replace the isolating screws. If necessary, ensure that the joint face of the isolating frame is clean. The isolating screws must be replaced as a complete set in order to ensure the correct clamping of the engine oil pan. Position a new joint (4) onto the engine oil pan (7).
- the isolating screws (8) and (9) to the engine oil pan. Do not install the isolating screws (8) in positions (X). Refer to Illustration. The isolating screws are held captive by the joint. Align the assembly of the engine oil pan with Tooling.
- the assembly of the engine oil pan to the isolating frame (12). Install the clip that secures the breather hose (not shown) in the correct position.

(X) Position of guide studs.
(Z) Position of short isolating screws.

Tighten the isolating screws to a torque of 22 N·m (16 lb ft). Tighten the isolating screws in the sequence that is shown in Illustration. Remove Tooling.


- the four remaining isolating screws. Tighten the isolating screws to a torque of 22 N·m(16 lb ft). Tighten the isolating screws in the sequence that is shown in Illustration.
- a new O-ring seal (6) to the drain plug (5).
- the drain plug (5) to the engine oil pan (7). Refer to Illustration. Tighten the oil drain plug to a torque of 34 N·m (25 lb ft).


If necessary, follow Steps to install the assembly of the dipstick tube.
- a new seal (3) to the tube assembly (2). Apply Tooling to the nut (1).
- the tube assembly to the engine oil pan. Ensure that the orientation of the tube assembly is correct. Tighten the nut (1) to a torque of 18 N·m (13 lb ft).
- the dipstick. Fill the engine oil pan to the correct level.
- If necessary, install the flywheel housing.

Engine Oil Pan (Cast Iron)

 Removal Procedure

The tractor engine should be mounted in a suitable stand and placed in the inverted position. Disconnect the breather hose (not shown) from the clip that secures the hose to the engine oil pan. Position the breather hose away from the engine oil pan.


If necessary, remove the assembly of dipstick tube. Loosen the nut (1) and remove the tube assembly (2). Remove:
- the seal (3) from the tube assembly. Discard the seal. Identify the position and orientation of the tube assembly.


Attach a suitable lifting device to the engine oil pan (7) and support the weight of the engine oil pan. The engine oil pan can weigh 100 kg (220 lb). Use Tooling in order to remove the four torx screws (11).
- the nuts (10).
- the setscrews (8) and (9). The setscrews are different lengths. Note the position of the different setscrews. Use the lifting device to remove the engine oil pan (7) from the cylinder block.
- the joint (4) from the cylinder block. Discard the joint.
- the drain plug (5).
- the O-ring seal (6) from the oil drain plug (5). Discard the O-ring seal.

Installation Procedure

Ensure that the joint face of the cylinder block is clean and free from damage. Inspect the studs in the cylinder block (not show) for damage. If necessary, replace the studs. Ensure that the engine oil pan is clean and free from damage.


Apply a bead of Tooling to positions (Y).


Align a new joint (4) with the studs (not shown) and install the joint to the cylinder block. Attach a suitable lifting device to the engine oil pan (7). The engine oil pan can weigh 100 kg (220 lb). Use the lifting device to align the engine oil pan (7) with the studs (not shown). Install:
- the engine oil pan to the cylinder block.
- the setscrews (8) and (9), the nuts (10) and the torx screws (11) finger tight. Align the rear face of the engine oil pan to the rear face of the cylinder block. Use Tooling and a feeler gauge in order to check the alignment between the engine oil pan and the cylinder block.


Tighten the setscrews (8) and the nuts (10) to a torque of 22 N·m (16 lb ft). Tighten the fasteners in the sequence that is shown in Illustration.


Tighten the remaining setscrews to a torque of 22 N·m (16 lb ft). Tighten the setscrews in the sequence that is shown in Illustration. Use Tooling to tighten the torx screws to a torque of 22 N·m (16 lb ft). Refer to Illustration.
- a new O-ring seal (6) to the drain plug (5).
- the drain plug (5) to the engine oil pan (7). Tighten the drain plug to a torque of 34 N·m (25 lb ft).


If necessary, follow Steps to install the assembly of the dipstick tube.
- a new seal (3) to the tube assembly (2). Apply Tooling to the nut (1).
- the tube assembly to the engine oil pan. Ensure that the orientation of the tube assembly is correct. Tighten the nut to a torque of 18 N·m (13 lb ft).
- the dipstick (not shown). After the diesel engine has been installed, ensure that the engine oil pan is filled with lubricating oil to the correct level.
