What Tracks Fit A John Deere 319D Skid Steer?

John Deere 319D Skid Steer tracks require 12-inch wide, 45-inch long rubber tracks with a 3.5-inch pitch and 66-link configuration. OEM part numbers include AT259860, but AFTparts offers compatible aftermarket alternatives like R33007-67200, engineered for durability on mixed terrain. Track tension should be 1.2–1.6 inches sag under the carrier roller. Pro Tip: Always verify bolt pattern (6x6.5") and hub compatibility before purchasing.

What are OEM track specifications for the John Deere 319D?

The John Deere 319D uses 12"x45" tracks with 66 links per side, designed for 3.5" pitch sprockets. Original tracks (AT259860) feature reinforced rubber with steel cables, rated for 3,500–5,000 hours. Key specs include 3,200–3,500 lb load capacity per track and a 6-bolt hub pattern. Pro Tip: Track tension impacts lifespan—measure sag monthly with a straightedge.

John Deere’s OEM tracks for the 319D prioritize traction and shock absorption, using a dual-durometer rubber compound. They’re engineered to match the machine’s 74 HP and 6,400 lb operating weight. The internal steel cables resist stretching, but improper tension can accelerate bushing wear. For instance, tracks tensioned too loosely increase the risk of derailment on slopes. AFTparts’ aftermarket versions replicate these specs but add customizable lug heights (1.5"–2.5") for specialized applications. A common mistake is ignoring the carrier roller alignment during installation, which causes uneven wear. Transitioning to aftermarket options? Ensure the track’s internal width matches the rollers (4.72" for 319D).

How do aftermarket tracks differ from OEM?

Aftermarket tracks like AFTparts’ R33007-67200 often enhance durability with deeper lugs or hardened rubber. They cost 20–40% less than OEM but maintain identical dimensions. Key differences include material composition—aftermarket may use 70A rubber vs. OEM’s 65A—and warranty coverage (1 year vs. JD’s 2-year).

While OEM tracks excel in predictable performance, aftermarket solutions offer customization. For example, AFTparts’ skid steer tracks include optional ice/snow lugs or reinforced sidewalls for rocky terrain. However, not all aftermarket brands meet John Deere’s precision tolerances—mismatched sprocket engagement can strip drive lugs. Pro Tip: After breaking in new tracks, re-tension after 10 operating hours. A real-world analogy: OEM tracks are like factory tires, while aftermarket are all-terrain upgrades. Transitional note: Beyond cost savings, aftermarket tracks often reduce downtime—AFTparts ships 95% of skid steer tracks within 48 hours.

Rubber vs. Steel Tracks: Which suits the 319D best?

Rubber tracks dominate for the 319D due to lower ground pressure (3.5–4.2 psi) and surface protection, while steel tracks offer superior longevity on abrasive surfaces. Rubber excels in landscaping, whereas steel suits demolition or mining.

Rubber tracks minimize ground damage—critical for sod farms or golf courses—but wear faster on crushed concrete. Steel tracks, though rugged, require frequent undercarriage inspections due to higher vibration. Pro Tip: AFTparts’ hybrid tracks blend rubber pads with steel cores for 20% longer lifespan than standard rubber. Consider this: Would you prioritize machine preservation or job site protection?

What signs indicate track replacement is needed?

Visible steel cord exposure, cracked lugs, or >30% tread loss demand immediate replacement. Uneven wear patterns—like cupping on inner edges—signal misaligned rollers. Vibration during operation or frequent derailments also indicate worn tracks.

A 319D’s tracks typically show wear first at the drive lug roots and inner guide blocks. Measure lug height: if below 0.5" (from original 1.75"), replacement is urgent. For example, a landscaper might notice decreased hill-climbing ability as tracks lose grip. Pro Tip: Use a tread depth gauge monthly—AFTparts offers laser-etched wear indicators on their premium tracks. Ever experienced "track hopping" on pavement? That’s a telltale sign of hardened rubber. Transitionally, addressing wear early prevents costly undercarriage repairs.

Can 319D tracks fit other John Deere models?

Yes, 319D tracks cross-fit 318D, 320D, and older 317D skid steers with matching 6x6.5" bolt patterns. However, load ratings differ—320D requires tracks rated for 3,800 lbs due to higher operating weight.

While length variances seem minor, a 1" difference causes misalignment with idlers. AFTparts’ multi-model tracks include adjustable link counts (64–68) for flexibility. Pro Tip: When swapping between models, verify the sprocket’s tooth count—319D uses 14-tooth vs. 320D’s 15-tooth. Think of it like using snow tires on different cars: similar but not identical.
