extreme noob question

[jettabrendan]

so i ordered my timing tools from "prothe" and i have a quick question. i used to know how to read dial indicators a few years ago when i was still in high school,  but now i forget. so long story short idk how to read them. i zeroed it all up and stuff and now i ust cant figure out where the needle is supposed to go once its back at tdc. anyone know off the top of their heads? i wanna get this done before it gets too dark out.

once you've turned the engine backwards and then zeroed everything and it is at TDC. You rotate the pump until you get to the desired setting.

Thanks to Vince's Guide.

The Bentley service manuals list the following "official"  settings:

Early Chassis:  (1977-1983)

1.5l non-turbo 1977-1980                                        0.88 +/- 0.05 mm

1.5l non-turbo 1980 with yellow dot                         1.15 +/- 0.05 mm

1.6l non-turbo  1981, 1982, and 1983 pickup            0.88 +/- 0.05 mm

1.6l non-turbo  1983 Rabbit and Jetta                        0.95 +/- 0.05 mm
1.6l non-turbo  1983 Vanagon                                  0.90 +/- 0.05 mm

1.6l tubo diesel (1982-1983)                                       1.00 +/- 0.05 mm

 

MK2 / A2 chassis:  (1985-1992):

Engine ME (1.6l non-turbo) 1985                             0.95 +/- 0.02 mm

Engine ME (1.6l non-turbo) 1986 and up                 0.90 +/- 0.02 mm

Engine MF (1.6l turbo)                                           1.00 +/- 0.02 mm

Engine 1V  (ECO diesel)                                         1.00 +/- 0.02 mm


MK3 / A3 chassis (1993-1997):
Engine AAZ  (1.9l turbo)                                        0.80  +/- 0.02 mm


 

Many performance tuners use the following:

-         non-turbo pumps:  0.95mm to 1.00 mm  (0.037" - 0.039")

-         turbo pumps:         1.00mm to 1.05mm (0.039" - 0.041")

I ordered mine from him as well.. Should me Imperial (inches) right? 0.039 for N/a or 0.041 for Turbo.. for the higher end of each setting.. Easier starting, a little more power.. but also more of the "marbles on metal pan" sound, and a little more NoX emissions.. but it wont harm the engine.

good luck.. hurry its almost dark!
