[Vwdiesel] Injection pump VE Bosch --- ( lets master the little devils )

[Doyt W. Echelberger]

OK Hagar....Here is a quote from my "Diesel Fuel Injection, 5th Edition."

Author is talking about the 4 cylinder engine injector pump:

pg. 13...."Idle speed, maximum speed, and injection timing can be adjusted 
with workshop equipment; the stop solenoid can be replaced, the fuel 
delivery valve body can be replaced, but any internal problems means 
replacement of the pump."

pg.15...."vane pump delivery pressure is between 3 and 7 bar, depending on 
engine speed, and it is controlled by the regulating valve.....(pump 
delivery pressure) controls the injection timing advance mechanism." ""The 
vane pump and distributor plunger injection pressures cannot be checked 
easily with normal workshop equipment."

pg. 16...."....cam plate and rollers push the plunger and pressurize the 
fuel to about 1,800 psi.

pg. 20........cold start cam stops affecting injection timing beyond 2,200 RPM.

pg.21....Checking ignition timing with cold start knob pushed in: Remove 
bolt from end of pump. Mount adaptor 2006 in pump. Turn crankshaft until 
flywheel TDC mark is aligned with pointer on transmission housing. Install 
dial gauge to read about 3 mm.  Turn crankshaft backward until dial gauge 
needle stops moving. Set dial gauge to read exactly 1 mm. Turn crankshaft 
forward to TDC. Dial gauge should read 0.88 mm movement (1.15 mm movement 
applies to only 1980 Rabbits which have yellow paint mark on pump advance 
cover.)
If necessary, loosen 4 mounting bolts on pump. Turn pump body until dial 
gauge reading is correct. Re-tighten bolts and recheck injector timing.
