Question of the week

[Phil Waterman]

Hi Cliff

I pulled the speedo cable out of my Pat 13 C60S this afternoon, the inside part which actually turns is 97 1/2 inches long.

The Pattern 12 Chevy C60L cable is 87 1/2 inches long.

I have three used cables sitting on the shelf without tags as to which truck they came off so sliding the cable out of the Patter 13 was the best way to find out which was which.

These cables have a thicker core than the civilian ones I have found. The transfer case end, have a special drive end. Do you have one to go by? I have gotten replacement cables from heavy truck parts suppliers outfits that specialize in big over the road trucks. Never had much luck with the normal automotive and light truck parts places.

Be very careful when you route your cable that you put the cable restraint clamps on particularly in the area of the master cylinder and starter, I had a speedometer cable chafe through on the brake light terminals get hot and then melt though the battery cable insulation that’s when the real fun started.

Cheers Phil
