A little help about my 603 Pump - Saterbonden - 01-21-2010
Hi, I've been reading the "IP Full Load Adjustment Procedure for the MW and M pumps" thread a little now and decided to try my self but since my english isn't the best I decided to ask a little before I do something stupid.
I've been wondering that the round thing at the back of the pump is, it's 2 round things that have some electricity cables attatched at the top of them, what are those?
I tooked some pictures to show what I mean but all got corrupted so I borrowed a picture from erling66 so you get the idea what I mean but that only got 1 of those I mean.

That's an electrical idle stabilizer. Controlled by pwm signal, idle can be raised with it (eg when A/C compressor engages, so that engine won't stall).
Not needed really, I have that in my pump but it's not in use.

Ok, so if I'm going to adjust the full load screw and the other ones nessesary I simply have to remove that and the rear governor plate to see all the screws?

Yes. The engine is mechanically set to idle at 500rpm but the computer uses that to bring it up to and keep it at 750rpm.
Adjust the pump, turning the coarse idle adjustment 1:1 with the full load, and it should keep working like normal.

Ok, then I'll take a look tomorrow hopefully or some day soon.

Ok it tooked a "little" longer then expected to take a look at the pump.
The fat screw at the bottom left shoud be the "Full Load" one? Just got a little unsure since it was a lot bigger then I belived it shoud be.
