To fit link bushes (Fig. 15)
It is strongly recommended that new bushes and new special washers are fitted and the old link bushes and washers discarded. It will be necessary to use the slotted support tube and the driving tube in the manner illustrated.
The procedure is as follows:
1. With the aid of packing blocks, set up the link in the press with the upper arm supported by the slotted tube as shown at “C”. Ensure that the slotted tube is properly located below the boss of the link.
2. Place the link bush and driving tube in position between the nose cap of the press ram and the
|
entrance of the boss, at the same time lowering the ram a little to support the assembly.
3. After making sure the assembly is vertical and the link bush is centrally located in the entrance of the boss, apply pressure gradually, preferably in stages, to the press ram until the link bush is fully home in the boss.
4. Remove the link from the press and install the fulcrum pin complete with two new special washers in the link according to the identification markings, ensuring that the special washers are correctly seated with their chamfered sides inwards towards the shoulders of the fulcrum pin.
