Measuring Guide - What track do I have?

STEP 1 

Know what machine the tracks are going on. Typically a salesperson can match the track by knowing the MAKE and MODEL of the machine. If the machine manufacture changed track sizes during production the salesperson may ne to know the serial number or the year your machine was made. Example: 2008 BOBCAT T190

STEP 2

Learning the track size. Typically you can check your existing track and find the track size. The size is usually stamped on the inside lip of the rubber track. In the diagram below the part number is the track size.

The track size is broken down into three measurements. WIDTH in millimeters, PITCH in millimeters and number of LINKS. The number will look like this 320x49x86. Width is always listed first but sometimes the number of links and the pitch can be in reverse order. As a guide 1" equals 25.4 millimeters. So if the track size is not stamped on the track you will have to measure it. Start by measuring the outside width of the track. There are industry standard sizes so it will be easy for a sales person to figure out the width. Next measure the pitch by measuring the from the center point of one link to the center point of the next link. Finally count the number of track links on each track. Follow the below diagram.

STEP 3

Learning the guide measurement. Sometime OEM manufactures don't share enough information about the tracks they use or the what type of guide the track links are set up on so the rollers have a good fitment. If needed this is how to measure the guide in three parts. OUTSIDE (A) measurement - from the outside of the lug to the outside of the lug. INSIDE (B) measurement - from the inside of the lug to the inside of the lug. HEIGHT (C) measurement - measure the inside height of the lug. Follow the below diagram.

STEP 4

Matching the roller type. There are generally three types of rollers track systems use. Single Flange, Dual flange, and Triple flange. Use the diagramed below.

STEP 5

Matching the sprocket type. There are two types of sprockets generally used. Sprocket driven The sprocket tooth inserts into the track guide of the rubber track and drives the track forward and backward. Center lug driven The rubber center lug of the rubber track fits into the sprocket which drive the tracks forward and backward.
