How to Replace Rubber Tracks on a Compact Track Loader
Replacing rubber tracks on a compact track loader or skid steer is a 45-to-90-minute job when done correctly. A single track can weigh 500 to 1,000+ pounds depending on the machine, so proper preparation and technique are critical for both safety and efficiency. Whether you're running a Bobcat T770, CAT 289D3, or Kubota SVL95-2, the process follows the same general steps.
What tools do I need to replace rubber tracks?
Before starting, gather the following:
- Grease gun with grease fitting socket (to relieve and reset track tension)
- Track bar or heavy-duty pry bar (minimum 36 inches)
- Floor jack or overhead hoist rated for track weight
- Socket set, wrenches, and basic hand tools
- Safety glasses and steel-toe boots
- A second person — never attempt track replacement alone
Step 1: Prepare the machine
Park on level, solid ground. Lower all attachments to the ground. Shut off the engine and engage the parking brake. Block the opposite track to prevent the machine from rolling. Remove any debris from the undercarriage — rocks, mud, and packed material should be cleared before you start.
Step 2: Release track tension
Locate the grease fitting on the track adjuster (usually at the front of the undercarriage near the front idler). Use a grease gun in reverse or crack the relief valve to release tension. The track should sag visibly once tension is relieved. On most machines (like the CAT 259D3 or Bobcat T590), there is a dedicated tension relief valve — consult your operator's manual for the exact location.
Step 3: Remove the old track
With tension released, use the pry bar to work the track off the front idler first. Once the track clears the idler, it will drop off the bottom rollers and drive sprocket assembly. Slide the old track out from under the machine. If the track is still tight, verify that all tension has been released — never force a track off the idler.
Step 4: Inspect the undercarriage
This is the best time to inspect your undercarriage components. Check the drive sprocket teeth for hooking, pointing, or uneven wear. Inspect the front idler for wobble, bearing noise, or seal leaks. Check bottom rollers for flat spots and bearing play. The general rule is to replace sprockets every other track change — roughly every 3,000 to 4,000 hours. Front and rear idlers typically last 2 to 3 track sets if seals remain intact.
Step 5: Install the new track
Slide the new track under the machine, draping it over the drive sprocket at the rear. Use the pry bar to work the front of the track over the front idler. Ensure the track is properly seated on all bottom rollers and that the drive lugs engage the drive sprocket teeth correctly. For directional tread patterns (common on mini excavator tracks), verify the arrow direction matches forward travel.
Step 6: Set proper track tension
Use the grease gun to pump grease back into the track adjuster until proper tension is achieved. The standard spec is 1 to 1.5 inches of sag measured at the midpoint between the front idler and rear idler, with the machine on level ground. Over-tensioning accelerates wear on sprockets, idlers, and the track itself. Under-tensioning causes derailment and uneven wear.
Step 7: Test and verify
Start the machine and slowly drive forward and backward 20 to 30 feet. Check that the track is tracking straight and the tension remains correct. Re-check tension after the first hour of operation — new tracks can stretch slightly during break-in.
How much do replacement rubber tracks cost?
Replacement rubber tracks typically range from $500 to $2,500 per track depending on size and tread pattern. The most popular sizes — 450x86x56 for CAT, 450x86x55 for Bobcat, and 450x86x58 for Kubota/Deere — generally fall in the $800 to $1,200 range. TrackTECH offers free shipping and a 24-month warranty on all rubber tracks. Use the Track Finder to find your exact size, or request a quote for fleet pricing.
