General
There are a number of special tools available to facilitate assembling the pumps. By

for maintenance and/or repair will be shorter.
These tools can be ordered from Johnson Pump or produced in the own workshop. The
article numbers for ordering are indicated in the tables under each drawing/picture
together with the dimensions of the tool in question (if applicable).
