Just killed the KDP - Problem with speed sensor
 

Hello all - I just bought my first diesel and really like it - Its A 96 CUMMINS 2500 - I hasve no previous wrenching experience and decided I could handle the KDP fix - When putting everything back together I broke the speed sensor (directly over the damper) - I bought a new one and put it in - The tach was reading but it would not shift into 4th gear - Well I messed with the gap and got it to work but I'm not sure its in the right spot

Specs say .049 to .051 - The feeler gauge i have starts with the thinnest saying .002 and .051 but this is very very thin -The thickest gauge says .032 and .813 using that one the tach won't even read - The very thin gauge that reads 0.002 and .051 just seem so thin - I guess I'm just tryin to figure out which mesurement on the gauge is the right one

Sorry for the long winded silly question and thanks for any help

Matt

that is the right one

the super thin one?

I would doubt it's the super thin one. Normally on feeler gauges, there is a standard measurement and a metric measurement. .002 inches is .051 mm.

If you don't have a gauge big enough to read .051 inches, you have to use 2 and add them together. Such as a .031 and a .020.
