How to Measure Track Gauge the Simple Way: Sprocket-to-Sprocket (Dozers & Excavators)

Track Width vs. Track Gauge (What You Actually Need)

When people say “track width,” they usually mean one of three things:

• Track shoe width (pad width)

• Overall machine width

• Track gauge (distance between the left and right tracks)

For undercarriage parts and fitment, the measurement you usually want is:

Track Gauge — measured sprocket to sprocket

No complicated math. No guessing centerlines.
Just a consistent reference point on both sides.

What “Track Gauge” Means (Plain English)

Track gauge is basically the machine’s stance — how far apart the two tracks sit.

It’s one of the key measurements used to match the correct undercarriage configuration, especially when the same model has multiple setups.

The Easiest Method: Measure Sprocket-to-Sprocket (From the Back)

Why measure from the rear?

• Drive sprockets are usually at the back

• Easy to identify

• Consistent reference point (unlike shoes or guards)

Where Exactly Do You Measure?

• Straight across the machine

• Near the middle height of both sprockets

• From one sprocket face to the other

Simple rule:

✅ Back of machine
✅ Sprocket to sprocket
✅ Measure across the middle

Step-by-Step: Quick and Clean

1. Park safely

   • Flat ground if possible

   • Parking brake set

   • Attachment down

   • Engine off

2. Go to the back of the machine

3. Locate both drive sprockets

4. Measure straight across

   • From the outer face of one sprocket

   • To the outer face of the other sprocket

   • Keep the tape level and straight

5. Write the number down

   • Use inches or mm

   • Don’t round aggressively

Two Tips for Accuracy

• Measure at the same height on both sprockets

• Avoid guards or sheet metal — measure the sprocket faces, not what surrounds them

Common Mistake to Avoid

Track pad width is not track gauge.

Pad width matters for some parts, but you can have:

• Same gauge

• Different shoe widths

So don’t mix the two up.

Why This Matters for Ordering Parts

Many machines come in multiple undercarriage configurations.
Getting track gauge right prevents:

• “Parts almost fit”

• Holes not lining up

• Wrong setup ordered

• Wasted time and return shipping
