User’s Guide and Installation Manual for Over The Tire Tracks

Now that you’ve purchased a brand new over-the-tire track system, you are ready to install, operate and maintain the tracks for optimal use. This user’s guide and installation manual provides the information you need to safely install, operate and maintain your McLaren’s V8 Series Maximizer, Protrac Diamond Tracks, Protrac Magnum Tracks and Protrac Rubber Track Systems.

Getting Started with Over The Tire Tracks

First, a few things to keep in mind:

  1. Before installation, make sure that you read and understand all instructions to avoid damage and injury.
  2. Check to see that all items are in the package.
  3. Take necessary safety precautions before and during track installation.
  4. Do not operate the equipment until the tracks are properly installed.
  5. First-time installers may need to contact one of our trusted staff for assistance but installation is pretty straightforward. For users with experience in installing skid steer tracks, the installation process usually takes between fifteen to twenty minutes.

Guidelines to Follow Before and After Installing Tracks

User safety is of utmost importance when operating any heavy equipment. Proper installation of tracks is crucial to maximizing safety. The guidelines below must be followed to guarantee user safety and proper operation:

  1. TRACK INSTALLATION AND REMOVAL SAFETY

As a safety precaution, first make sure that the area where you’ll be installing or removing tracks is clear of clutter and people who are not assisting with the installation. Keep the boom of your skid steer elevated and locked. Also check to make sure that the engine is off before any installation or removal.

  1. TRACK SLACK ADJUSTMENT

Make sure you have between 1” to 3” of track slack. 2” is ideal. Adjust as necessary, keeping in mind that if tracks are too tight, it can damage your skid steer. Loose tracks between 2” and 3” protects the carriage and pin bolt life.

  1. USE OF THE RIGHT TIRES

The type of tire you use with your McLaren tracks is important to prevent damage to the machine. Do not pair your tracks with flat-proof tires such as solid rubber tires or foam-filled tires as these can damage the skid steer. Instead, use McLaren Nu-Air tires, which are the only flat-proof tires that are suitable for McLaren OTT tracks.

  1. TIRE PRESSURE

Check to make sure that you have the optimal tire pressure recommended by the manufacturer. Usually, this number is written on the sidewall of the tire in US pounds per square inch (PSI). If the tire has the tire pressure rating in kPa, conversion is simple.

Use the following equation:

  • PSI = 0.14504 x kPa

As an example, if the kPa tire pressure reading is 490 kPa, multiply this number by 0.14504 to get the PSI. So:

  • PSI = 0.14504 x 490 = 71.0696

Rounded, the tire pressure is 71.1 PSI

  1. TRACK TO TIRE FIT

To avoid premature wear and tear of the sidewalls of the tire, it is crucial that the inside track to tire fit is ideal. If the fit is too tight, you run the risk of damaging the tire. We recommend that you leave between 1/2” to 3/4” of space between the inside of the track and the tire. This way, you prevent debris from intruding and getting stuck between the inside of the track and the tire.

  1. TIGHTNESS OF BOLTS, NUTS AND PINS

A loose bolt can puncture your tire if it slips off and gets stuck in the sidewall. It is important that all nuts, bolts and pins are tightly secured to prevent damage. Use an automotive air wrench or a torque wrench to tighten nuts as needed. If using a torque wrench, make sure that you use a torque rating of 100 foot pounds.

Before you install OTT Tracks

  • Prepare the area where you’ll be installing the tracks, removing clutter and clearing space. Also take the necessary safety precautions to avoid personal injury.
  • You may need to install wheel spacers if the tires do not have the proper clearance for you to install the tracks. Check track clearance by disconnecting one track unit from the track’s assembly. Use this track unit to see if the clearance is sufficient for installation.
  • We recommend installing one track side at a time, especially if you are installing tracks for the first time. Once you get a hang of it, you will be able to install both tracks at a time.
  • Note that the tread lugs on a Protrac Magnum track are directional. When viewing the track from the top, the thick solid bar of a Magnum track should face the front of the equipment once it is installed.

OTT Track Installation Instructions

Installation Method 1

  1. First place the tracks side by side, parallel to each other, making sure that the distance between the tracks is equal to the distance between the left and right tires.
  2. Raise the boom of the skid steer and lock. This minimizes the risk of injury as you install the tracks. Follow the instructions in the owner’s manual for your machine to raise and lock the boom.
  3. Carefully drive your skid steer over the tracks. Stop the machine when you are about halfway on the tracks.
  4. Carry and fold the back end of the tracks over the back tire of your equipment.
  5. Do the same with the front ends of the tracks, folding them over the front tires of your machine.
  6. Assemble the installation tool as follows:
  • The installation tool is made of 2 C-Clamps and a threaded rod.
  • Screw on the C-clamps to the rod.
  • Avoid over-tightening the installation tool when using the it on a track, as this can damage the tool as well as the tracks. The installation tool is designed to withstand the pressure applied during installation but it can break if it is over-tightened.
  1. Under the first open section of the track, insert the assembled installation tool. Also connect the other end of the tool to the opposite section of the track.
  2. Using the ratchet, bring the two track ends together by placing the ratchet on the end of the threaded rod (the square end).
  3. Get the open track sections close enough to insert the dog-bone links into the slots of the track sections.
  4. On the outside of the track, insert the carriage bolt. Make sure all the carriage bolts are tightened. Tighten the bolts to 100 pounds of torque pressure.
  5. You can now remove the installation tool after loosening it.
  6. Drive the equipment forward to make space to insert the carriage bolt on the inside of the track. Once inserted, tighten the bolt.

Installation Method 2

Keep in mind that OTT tracks weigh a lot so you might need to use a heavy duty rope to get the track over the tire. Below is an alternative method for installing over-the-tire tracks:

  1. On the last track chain pad, tie one end of the rope.
  2. Extend the rope over and along the tread of the tire.
  3. Use the rope to encircle the front end of the tire tread.
  4. Tuck and secure the rope under the tire.
  5. Move the equipment forward to pull the track half-way over the tire’s rear end.
  6. Carry the rest of the track and put over the front tire.

Track Adjustment, Sag, and Tension

The ideal track sag is 2” but anywhere between 1” and 3” of track sag is recommended. If the track sag falls outside of this range, adjusting the position of the pins between the inner and outer holes will allow you to loosen and tighten as needed to get the required track sag. Maintaining the required track tension prevents the tracks and undercarriage from damage. It is crucial to always have the right track tension before operating the equipment.

An inner hole adjustment will loosen or tighten the track by about 3/4”. You can make one or two inner hole adjustments as depicted in the following diagrams:

OTT Track Maintenance & Upkeep

A few maintenance practices to keep in mind:

  • Check Track Tension Periodically

Every 100 hours of track use, check the track tension and adjust as needed. That way, you protect the tires of your equipment from damage and extend the work life of the track.

  • Break-in New Tracks

It takes approximately 20hrs of track use to break-in new over-the-tire tracks. This is the amount of time it usually takes for the tires to seat themselves on to the OTT tracks properly.

  • Avoid Pivot and Sharp Turns

To preserve the service life of the tracks, limit standing pivot turns and sharp turns as much as possible. Pivot turns and sharp turns accelerate wear on the track and should be avoided as much as possible. Especially avoid making sharp turns during the 20hrs of track break-in. Wait until the tires are properly seated on the tracks before making sharp turns if necessary.

  • Rotate Tracks Regularly

Every 100 hours of Protrac Rubber track use, rotate the tracks. If there is any indication of uneven wear, we also recommend rotating the tracks. This helps extend the service life of the track system.

  • Take Safety Precautionary Measures

Always take safety precautionary measures when inspecting the tracks for possible track problems. Doing this ensures that you are protected from any injuries. Turn off the engine of the equipment before performing any troubleshooting. If you need to, wear gloves and remember to lock the boom of your equipment before troubleshooting track issues.

  • Storage

When not in use, tracks should be stored in an appropriate place. We recommend storing your tracks in a sheltered, cool and drive environment to protect them from direct sunlight and rain.
