Engine/Transmission (1994 - 1998) 12 v timing questions

[MMeier]

(1) What size is the nut on the front side of the pump. . IIRC, I saw 30mm? (2) Anyone have a link to a mm to sae conversion chart?... as in what does 5. 3mm equal in thousandths of an inch? TIA!!

1-3/16 inch, I believe.

On the same topic, looking at from the front of the truck, which way does the motor turn. I am trying to conceptually determine which rotational way would advance or retard the timing.

 

[K5IP]

Which way? The easy way to remember is to look at the fan to see which direction will pull air in from the front.

10-4.



As dumb as it sounds, I was thrown off in that the fan is on a clutch. In my initial, look, I came away thinking that it was not connected to the crankshaft.



Thanks.

That is not always clockwise on the fan. It is on the crank, looking at the front of engine.

(5. 3 mm divided by 25. 4 mm = . 20866 inch)



Just take any metric measurement and divide by 25. 4 and your have your answer in inches.

The nut is 30 mm (=1. 811”) which is close to 1-3/16” (=1. 1875”). My column has a conversion chart in Issue 56, p. 103. To convert mm to inches, multiply by 0. 03937. So, 5. 3 x 0. 03937 = 0. 20866 inches. Envision it this way, each mm is about forty thousandths of an inch. I put P7100 pump timing vs. plunger lift specifications in Issue 55, p. 95.

You know a conversion chart sticky would be nice... .

I posted a link above to a web site that has the conversions that do the calculation for you.
