Stairs have a good reputation, they may also want to test the injectors. Could be expensive rebuilding it, maybe a specialist in England would be cheaper on an exchange unit?

Adam,
I wonder if a tractor repair place like Green Diamond or the place in South Alton(Kings something or other...) might have a mechanic who knows these pumps.
I am watching with interest.
Good luck.

Thanks John! Yes, I am certain it is the pump but good to hear someone agree.

CAV DPA? I thought I have a CAV DPS pump... lots of info out there for the DPA which appears to be quite similar.

I have two pumps but both were stored for similar time under the same conditions so the internals are likely in similar condition. My next step will be to pull off the top cover (seems a bit of a fiddle but doable with no special tools/calibration/etc) If I can't free things up I may swap the spare and see how that goes.

All that said, given the time and money I have already spent on the engine (a rebuild) one could argue it is worth getting a pump rebuilt... a rebuilt engine with an unhealthy injection pump would be a shame. Just need to look into where that could be done! I know of one diesel IP specialist in Dartmouth (Stairs Diesel) but am uncertain of any others..

It is almost certainly the pump.  You can do a search on the CAV DPA pump for an exploded diagram. You may be able to fix it your self.

Adam,
Have you had any luck with the engine?
I am curious if your engine vibrates a lot when it is running. Mine does. Not sure what 'normal' is!
Thanks,
Colin

Haven't looked at it much again, I have hope it will sort itself out but am not optimistic! Leaning towards the injection pump internals being stuck at wide open throttle. May end up sending a pump off for rebuild.

Having the truck on the road this spring is a realistic goal, you are more than welcome to have a look once it's sorted.

Stay tuned!

Adam,
If there is anything that I can do to help by you having a look at my engine, please let me know.
Any progress is good!
Colin

Thanks! Appreciate it.

Have been thinking about the problem and am moving away from my leaking injector theory. I believe leaking injectors would be a poor start/ruff idle sort of problem while I am having a max rpm only problem. Even if the injectors are leaking, the injection pump still meters a defined qty of fuel... my issue seems more like an internal failure in the injection pump... as in the mechanism that meters the fuel is stuck at wide open throttle...

Had to service one of my wiper motors. It has been sounding quite noisy, but fortunately only needed some grease added to the armature in the gearbox bushing. Sadly, I fried the switch in the dashboard. I'm not sure how, but I assume I grounded the wire making the connections, or had the insulator improperly positioned in the case. The switch isn't repairable, so I'm looking for a replacement, if anyone has one (see Wanted section).

Regards,

Stephen

Wanted / Wiper/Washer Switch Needed
« Last post by Ulysses on January 07, 2018, 08:27:38 PM »
I need a replacement for part number 579006 wiper/washer switch. This is the kind that rotates to turn on and off and pushes to activate the washer pump. I have the knob; I just need the switch. It is the single speed version and has a hex shaft. I'll take the 2-speed version if that's available, though.

Thanks, Stephen
