Wash all components in a suitable aromatic solvent. When dry apply hydraulic fluid immediately to prevent moisture collecting.
1 Install a new shaft seal 2 into the mounting flange 3, with the part number of the seal facing outwards.
Press the new seal into its bore until fully seated.
Install the circlip 1 into its groove in the mounting flange 3.
2 Place the front 6 and rear 13 bearing blocks on a clean work bench with the E-seal grooves facing upwards. Apply a coating of petroleum jelly to the grooves. Apply a coating of petroleum jelly to the Eseals and back-up seals. (This will help keep the seals in place during assembly.)
3 Place the E-seals 5 and 14, flat side outwards, into the bearing blocks 6 and 13. Carefully place the backup seals 4 and 15, with the flat side outwards, in the respective groove made by the E-seal and the groove in the bearing block.
Note: In the centre of the back-up seal and the E-seal there is a “notch”. Make sure these notches line up, so that the back-up seal sits flush with the E-seal.
4 Place the mounting flange 3, with the seal side facing downwards on a clean flat surface.
5 Apply a light coating of petroleum jelly to the exposed face of the front bearing block 6.
6 Insert the drive end of the driveshaft 12 through the bearing block 6 with the seal side down, and the open side of the E-seal pointing to the intake side of the motor.
7 Install a sleeve over the driveshaft threads to protect the seal 2 and carefully slide the driveshaft through the seal 2. Remove the sleeve from the driveshaft.
8 Install the idler gear shaft 11 into the remaining position in the bearing block. Apply a light coat of clean hydraulic oil to the face of the driveshaft and idler gears.
9 Pick up the rear bearing block 13, with the seals facing upwards and the open ends of the E-seals facing the intake side of the motor, and place over the driveshaft and idler gear shafts.
10 Ensure the dowel pins 8 are in place in the housing 9.
Note: On later housings there are two long dowels through the housing that locate in the front mounting flange and the rear cover. These replace the four short dowels item 8.
