Solution:
1. close the fuel line
2. remove the oil filter (this has to be removed anyway). clean the area and put some cloth on the open end of the filter housing.
3. mark the throttle wheel and remove the spring and wheel (leave the cable on)
4. measure the hight of the bolt for minimum throttle and remove it.
5. remove the 1/4 SAE 12-point bolt on the throttle end which holds the housing.
6. pull the throttle shaft out of the housing
7. replace the o-ring, ad some vaseline (only on the o-ring)
8. push the shaft back in by some force
9. screw in the 12-point 1/4" bolt which holds the housing
10. reinstall the throttle wheel and spring
11. screw in the minimum throttle bold to the earlier measured height.
12. open the fual line
13. open the most top bolt on the governor housing and manually pump diesel till diesel comes out this vent. Close the bolt.
14. reinstall the filter.
15. slacken 2 of the injectors fual lines
16. start-start-start-start the engine till diesel comes out the injector lines. Tighten them and do the same for the 2 other lines.
17. Engine must run now without leakage.

(in dutch for who is interested and to help my dutch friends using google: cav DPA hydraulische pomp van Perkins 4.108 lekt diesel uit de gashendel of gashendel as).

Goodluck with this simple repair (if you know it's simple.....).

I know its been a decade since you posted this, but, thanks.

Don't forget the safety wire to keep the 12-point bolts from loosening - that got us when we did this. Leaked a lot of fuel when we ran the engine - and we ran it only once before we fixed it (with the safety wire).

Roger that! I'm actually doing it tomorrow. Hoping it works out.
