Disassembly Instructions

1. Remove the lift cylinder assembly by following operation 2.09A-04, steps 1 to 11.
2. Take out the two bolts.
3. Detach the support bracket.
4. Withdraw the piston from the cylinder.
5. Remove the piston seal and ‘O’ ring if required. Inspect all components for wear or damage and replace any defective parts.

Reassembly Instructions

1. If piston seals have been removed, apply transmission oil to the ‘O’ ring part of the seal and fit it into the piston groove.
2. Lubricate the outside of the tapered guide with mineral oil (MF.420 for MF.431 tractors, MF.453 for MF.461 tractors). Place the guide on a firm, flat surface. Position the seal on the guide and push it carefully down the taper of the guide until it extends past the end. Position the lip of the seal on the piston at the closed end and press the seal off the guide onto the piston, fitting it into the groove on top of the ‘O’ ring.
3. Insert the piston into the wide bore end of the sizing ring, pushing it through until about 12 mm of it extends from the end of the ring.
4. Lubricate the bore of the cylinder with transmission oil, then align the protruding portion of the piston with the cylinder bore mouth. Push the piston through the sizing ring into the cylinder.
5. Reverse steps 1 to 11 in operation 2.09A-04 to complete the assembly.
