Overview

Note: General rule for installation: Tach cable should be installed as straight as possible - the inner cable length will decrease 11/16" per 360 degrees of bends.
  • 1. Select the proper length from the listing, but measure old tach cable to verify length in chart is correct for your aircraft, as tach cables can vary from aircraft to aircraft. Over-length cables can cause problems - order one that fits the installation.
  • 2. Measure original cable from end of Ferrule to end of Ferrule when fully extended.
  • 3. Inner tach cables are measured end to end.
Inner assemblies have male ends only. One end is squared and the other is keyed. Tach cable assemblies have 7/8-18 on one end and 5/8-18 on the other, female nuts only.

Note: Custom length tach and inner cables are available. Please contact sales for price and lead time of custom cable. You will be required to provide length and rotation. Additional information of aircraft, engine, make, model & dash number may be required.

Note: General rule for installation: Tach cable should be installed as straight as possible - the inner cable length will decrease 11/16" per 360 degrees of bends.

Available in left and right lay rotation. Add -R to the part number for Right Lay.
  • 1. To determine cable rotation, note the rotation direction of the tach drive socket on the engine while looking directly at the tach drive on the engine.
  • 2. If the drive socket rotates clockwise, a right lay inner cable is required.
  • 3. If the drive socket rotates counter-clockwise, a left lay inner cable is required.
  • 4. The rotation direction of the tach needle does not affect which lay should be used.

Tachometer Cable 29-1/2 Left Lay
October 13, 2021

Bought this item to replace failed one. Learned there is a left and right lay to the cables twist. Old cable had wrong direction twist to it. Sales person at Spruce was a big help to me in selecting correct cable for my engine set up. Construction of cable is very high grade.

Cable fit my 1964 Clark end loader/backhoe perfectly. Due to the thoroughness of your website, I was able to pick out proper ends and lay for this cable with relative ease. OEM cable hasn’t been available for 50 plus years.

This cable is captive on the engine side such that it will not put pressure on the tach input. Some tachs like the Mitchell, require a captive cable to keep pressure off the tach, this cable will satisfy that requirement.

Q: Hello, can you supply a 16 ft long cable for a tachometer?

Yes, please use part number 10-03373 (TACH CABLE 192") which is a 16 ft tachometer cable.

Q: Regarding Tachometer Cable: P/N: 10-15900 Right Lay or Left Lay, are we looking through the prop to the tail or are we sitting in the seat looking forward at the back of the engine?

The rotation is determined by looking at the tach drive on the engine. Please review the PDF on our web page for a detailed description of how to determine the tach rotation.

Q: Is this a captive or non-captive cable? Non-captive cables cannot be used in several tachs.

All tach cables listed on this page are captive.

Q: Do these Tachometer Cables come with the inner cable?

Yes, they come with the inner cable.

Q: Are the 10-16300 or 10-16000 cables right or left hand lay?

All stock cables are left lay (counterclockwise).

Q: Are the tachometer cables captive ?

Yes, these tachometer cables are captive.

Q: Is it possible to receive a form 8130-3 for the Part # 10-15700-R?

No, these are not FAA approved cables.

Q: Is this tach cable compatible with Lycoming engine and tachometer?

Yes, they are commonly used on Lycoming engines.

Q: Looking at your web site for ordering tachometer cables your site says to look at the rotation direction of the tach drive while looking at the engine. My question is, looking at the engine from the front or rear? Which rotation is most common on Lycoming engines?

Per the manufacturer: Front or rear of the engine doesn't matter because you should be looking at the port in the engine itself where the tach cable will be inserted into the engine. That rotation is what we go off of and most Lycomings have a clockwise rotation which is right lay.

Q: Are these tachometer cables FAA TSOd?

No, these cables are not FAA Approved.
