Complete Tractor New 1607-2717 Tachometer Replacement For Allis Chalmers D15 I-60 Indust/Const I-600 Indust/Const 236777 70236777

What It Is

This is an aftermarket tachometer replacement designed for Allis Chalmers D15, I-60, and I-600 industrial/construction tractors. It measures engine RPM (revolutions per minute) to help you monitor operating speed and adjust throttle for optimal mowing or PTO work.

Fitment & Compatibility

Before buying, verify your tractor’s model number exactly—this fits Allis Chalmers D15, I-60, and I-600 industrial/construction models only, not standard lawn tractors. Cross-reference with OEM part numbers 236777 or 70236777. Measure the tachometer mounting hole diameter (typically 2-1/8” or 2-5/8”) and check the drive cable connection type (mechanical cable vs. electronic). If your tractor uses a different cable or mounting depth, this won’t work without adapters.

Key Things to Know

• Low reliability rating: 2.6 stars from only 2 reviews suggests potential quality issues—may fail early or read inaccurately.
• Installation complexity: Replacing a mechanical tachometer requires removing the dash panel, routing the cable correctly, and ensuring the drive gear engages without binding. Expect 30–60 minutes for a first-time install.
• Compatibility gotchas: Aftermarket tachometers often have slightly different face graphics, backlight color, or bezel size than OEM. Check that the drive cable length matches your tractor’s routing path.
• No warranty info listed: Without a stated return policy or warranty, you’re taking on more risk if the unit arrives DOA or fails quickly.

Should You Buy It

Consider this only if you need a budget replacement for a non-running tachometer on an Allis Chalmers D15, I-60, or I-600 and are comfortable with potential fitment adjustments and lower reliability. For critical use or restoration, spend more on an OEM or known aftermarket brand with better reviews and a warranty.
