Johnson P120 pressure pump, repair possible ?

[hansverh]

Hi all,

This morning my (fresh) water pressure pump started leaking at it's base. It's a Johnson P120, 11 liter / 2.9 gallon pump.
Quickly replaced with the spare one.

Question:

Before I throw it out I want to have a look at its internals is it even possible to repair such a pump ?

Thanks.

What does the service manual say?

Found a manual online saying you can replace the complete pump assembly. Cost more than a brand new pump. So figure . . . . I'am going to leave opening it up to have a look-see for a rainy day.
In the meantime enjoying the beautiful mild winter weather here in New Zealand.
