Re: Need Diagram - Perkins 4-107 Fuel Injection Pump

Could I also get the PDF with diagrams on the Lucas CAV pump type?

I have a 1984 Perkins 4-108 with the Bowman heat exchanger. It has the fuel injector pump similar to the one on page N8 in the workshop manual. It is a Lucas CAV hydraulically governed (early and current) DPA pump type described in the manual.

Is this part number 3247F190, and if so is it the subject our your article?

Thanks,

Morgan38

Re: Need Diagram - Perkins 4-107 Fuel Injection Pump

I too have a fuel leak at the throttle shaft on my Perkins 4-107.
Should this be repaired by a professional?

The seals 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.
