Extend an old cps.
I added .055 to the end of a cps with
a motorcycle valve shim. also removed the o-ring.
This will allow you to measure from the cover to the mount
face of the cps.

I did start to mod a cps for the use of a dial gauge.
Never got around to finishing it. I run fluidamper's
so its a pita.

You have to check how true the cam gear is.
The cam gear is heated to 500*f then pressed onto the cam.
Allowable is .008 runout. Then cam thrust has to be measured.

Ok guys i found a CPS i like. when i had the original black CPS the truck ran smooth and got good mileage, but i noticed after switching to the grey CPS that i had a rough idle, codes for cylinder 3 & 8 on CCT, less mileage(20mpg w/ black down to 16mpg and best of 18mpg w/ grey CPS). it just didn't feel like it ran right at all so i went and got another one. still idled rough and bad mileage. found out about this CPS and its awesome the difference it made for me. the IH part # is 1876736C91.
this CPS can only be had from International. Ford doesn't have these CPS's. my truck idles smoother now than it has in a long time and the mileage picked back up to 22mpg!!!
haven't run a CCT yet, but i think that the CCT might be better this time w/out the grey CPS. i heard the grey will give codes for those cylinders.

I am going to try it soon! I changed my CPS about the same time I changed my K+N to the 6637 and my mileage went from bad to worse! I don't really notice any sluggishness but my fuel mileage is cwap! I want to change the CPS 1st then rebuild the fuel bowl/FPR w/O rings. Thanks for the part number and the info behind it!

Here is some info of the past 2 cps's thanks to pocket.

The air gap will be larger with the grey sensor.
I backcut the mounting face of the grey sensor
to get it in spec (average is .010/.020 removed).
Some remove material from the cover.
That i will not do.

What is the lenght from the mount face to the tip?
Dont use the epoxy dots for the measurement.
It easy to measure off of a sheet of glass.
1.154? I dont have my records here.
