Guage cluster and speedometer cable questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**CPNE** · 04-13-2007, 02:26 PM

I can take apart 67-72 gauge cluster with my eyes closed but have never messed with the 73-87 variety. These questions pertain specifically to an 81 cluster with oil pressure, temp, and volt gauges. No tach.

I have a squeeky speedo cable and I want to lubrucate or replace it.

Questions:

1. It's difficult at best to reach in behind the cluster. Is it best to remove the cluster to gain access to wherer the speedo cable attaches? If not, what's the best way to access? If so, any tips on best way to pull cluster from front? (see question 3)

2. Does the speedo cable have a threaded attachment or is it clipped on? How do I detach from back of speedo?

3. If I do have to pull the cluster out from the front, what all is attached behind it? On 67-72, the oil pressure has a separate hard line to it. Is the 73-up oil guage electronic? Other than the possibility of a separate oil line, is there just a wiring harness to detach?
