When I first got my '88 1.6TD, I took some measurements ...Chew on this!...
The Bosch VE pump was out by 5 thou. (0.0254 x5)=0.12mm...reading 0.88mm; Nate
and Co. had suggested 1.0mm.
The total thrust of pump piston is 90 thou or approx 2.3mm...This is achieved
by a thrust of approx 2 thou per tooth advance on flywheel peaking to 5 thou
per flywheel tooth, before leveling off on pump cam peak...'H' perhaps you or
someone else can check thrust rate on an  N/A for comparison...
