Perkins fuel injection pump installation

[Bill Dietrich]

Hi,

The fuel injection pump on my Perkins 6.354 started leaking fuel, so I'm having a rebuilt pump shipped in. I thought I could just bolt it in and go, but now I'm not sure. Is there a manual or procedure for installing these and adjusting timing ? The old pump was a CAV DPA rotary 6-cyl pump.

Please don't send info about pumps on other types of engines; I'm pretty sure they're all different. For example, this pump doesn't rotate on its mounting to set timing. I'd really like a CAV DPA pump manual, if you know where I could get one. Or if someone has a 6.354 shop manual that has a page or two on installing the injection pump, I'd love to know what it says.

Thanks,

Bill

First, my bona fides... I just removed and replaced the injector pumps on my T6.3544m Perkins. The same as yours, but with turbochargers. Really easy job to replace them. First, make sure that the keyed gear at the bottom of the pump is correctly aligned. It will only go in one way! Next, you will notice a punch mark on the base of the pump. Might be a little difficult to see thru the paint. It's below the hole where the outside stud passes thru the base, on the vertical side. It aligns with a similar mark below. If the shaft gear and the punch mark are in alignment, the 'timing' of the pump is perfect. Tighten the nuts, replace the injector tubing, and replace the linkage. That's it!

Question: May I ask why you chose a rebuilt pump? The reason I ask is that since the change to low-sulphur diesel, I'm told 'all' of the Perkins injector pumps leak at the throttle shaft input. These (including mine) are easily repaired for less than $100. Mine was done by my local Perkins dealer. The benefit is that all of the original governor/idle screw settings remain intact.

Best of luck with your project. I hope this helps!

Regarding "Mine was done by my local Perkins dealer"..
this thread is a little old, sorry! I'm in Okeechobee, FL: where is your "local Perkins dealer"? I have the same problem: leaking around the throttle input. If it's easy to do, perhaps (if I could get the replacement seal) I could do it "in situ", without removing the pump/governor.
Thanks!
