Replacing Front Oil Seals
1. Follow the procedure for dismantling the pump head and removing the product seal.
2. There is now free access to the front bearing retainers which are held in place by
three socket head cap screws on each one. These should now be removed.
3. A lever may have to be used to separate the retainer from the gearcase face, as a
silicon sealant bonds the retainer to the gearcase.
4. The oil seals can be simply pressed out from the retainer and replaced using a
suitable tool. A fine grade abrasive cloth should be used to clean the internal faces
of the retainer before refitting new oil seals.
5. Thoroughly clean off the old sealant from the retainer and front face of the
gearcase. A new application of silicon sealant can now be applied.
6. Replace and tighten the six screws evenly to the recommended torque values. See
page no. 21.
7. Reassemble the pump head and product seals to the detailed procedures.
