High Pressure Pump Servicing Instructions – Page 8
3.
Remove the stainless steel case (item 3 / 4) where low pressure seals (item 2) were installed. Tightness
of stainless casings varies from pump to pump. It may be possible to remove the rings by inserting a
finger and pulling outwards. If more force is necessary, use a 17-18mm diameter object (such as a
blind bearing puller or screwdriver handle) and gently pull them out with a slight rocking motion. Since
they are being replaced, damage to the old packings is inconsequential.
Important:
take care not to
score or mark the manifold's machined surfaces.
4.
Remove high pressure seals (item 5 / 6) using your
finger by gently pulling them upwards. If more force
is necessary, try using plastic or timber tools in order
to avoid damaging machined surfaces of cavity. Take
careful note of the seal’s orientation in order to
correctly insert the new seals later.
5.
Thoroughly clean and inspect cavity for unusual wear
or cracks.
6.
Press the glyd high pressure seal (item 5) into square
high pressure seal (item 6).
