Yes. Have it. The Isspro speedo switches calibrate both speedo and odometer. The Peterbilt speedo that I have in the truck is an Amtek 500 series. As I read the info, the speed is set with a screw, and the switches are set to calibrate the odometer. So need to have a calibrated mile to get it set, I think.

On edit - this sender (isspro) may create too many pulses per rev for my ametek speedo. Checking with them on Monday to make sure.

 

Better to make that a ten mile check with markers ending in 0.

 

Someone with digital speedo in a car can pace beside you and communicate speed readings by phone or cb. This will get you " in the ballpark"

 

Frozen as in how? Pins in the end? Ram in the bore?

 

Can you take a cutoff wheel on a die grinder or 4 1/2" right angle grinder and cut off the pin? Then drive the remaining pin through towards the frame. Is there room between the yoke of the mounting bracket and the tang of the cylinder to slip a cutoff wheel in there to cut off the pin? You may need to heat things to prevent breaking anything when you drive out the pieces of pins.

 

Pictures help. But if you have room, weld a thick washer on each side of the old holes. Sounds like you're making a new pin anyway. There's a fancy name for them but they're around a 1/4" thick material.
