number on it. its a 1973 perkins 4-107 older model
for the throttle arm is just two small o rings. The fuel pump
is a CAV DPA injection pump - widely used in tractors, boats "London Taxi's" and billions of other applications.
You will need a cover gasket
set - Just search Google
for "cav dpa top cover gasket" and you will find plenty of offers.
It is very important that when you lift
the cover that you make some photos or notes of which holes the springs is fitted so that your pump remains with correct settings.
If the space is not too limited around your engine
, this job is easy to do without removing the pump. If the throttle axle is worn - I also noted that a lot of suppliers sell a complete kit with new cover and axles - Cav Top Cover Kit Lucas DPA Diesel Injection Pump Gasket Leak Delphi Throttle | Ford Tractor DieselFord Tractor Diesel
Pleas send me a private message with your email
and I can send to you the manual for this DPA pump.
