CAT 093-1937 SHOE TRACK

CAT 093-1937 is a Caterpillar original double-tooth medium-duty track shoe, compatible with small excavator/bulldozer chassis with a pitch of 190mm and a width of 500mm. Suitable for low-to-medium impact applications such as earthmoving and municipal work, it balances steering agility and track link protection. It belongs to the same series as 093-1932/1933/1936, with highly consistent core specifications.

Item Details
Part Model: CAT 093-1937 (0931937) Double Grouser Track Plate

Material and Process: Rolled boron alloy steel + overall heat treatment, hardness HB380–420, hardened layer ≥8mm; CAT yellow primer + wear-resistant coating, salt spray ≥480h

Structure Specifications: Double Grouser, standard hole positions, non-self-cleaning/non-offset; suitable pitch 190mm, track plate width 500mm; comes with 2 sets of track bolts and nuts (recommended 9W-3361/6Y-0846)

Single Weight: Approx. 25.6 kg (56.4 lbs)

Rated Operating Conditions: Moderate impact, non-abrasive environment; check wear/bolt torque every 500 hours

Compatible Models: Mainstream compatible CAT E70B, 307, 312 Small excavators, D4 and D5 series bulldozers; final verification is based on chassis serial number + mounting hole spacing.

Installation Parameters: Bolt specifications 1/2″-20 UNF, installation torque 380–420 N・m, tightened in two crisscrossing stages.

Adaptation and Application Points:

Functional Positioning: The dual-tooth design results in low steering resistance, suitable for municipal and pipeline construction scenarios with frequent turning, providing stable ground support and traction, and protecting track links.

Matching Specifications: Replace track plates in pairs from the same batch; mixing different materials/thicknesses is strictly prohibited; bolts should be tightened in two crisscrossing stages at 380–420 N・m, and the torque should be checked again after the engine is warm to prevent loosening.

Replacement Standards: Tooth wear > 40%, plate cracks, hole deformation / Replace track plates immediately if they are stripped or the hardened layer has peeled off; do not weld cracked plates for repair.

Installation and Maintenance Procedure: Stop the machine on a level, hard surface. Support the machine body, loosen the track tension cylinder, and remove the old track plates.

Clean the mounting surfaces of the track links and the bolt holes of the new plates, removing rust and oil.

Tighten the track in two crisscrossing stages with a torque wrench (initially 70% torque, final 100%).

Restore track tension, and after 10 minutes of no-load operation, recheck the torque.

Maintenance Cycle: 500 hours under standard operating conditions; 300 hours under high dust/humid conditions. Inspect tooth surface wear, plate cracks, and bolt anti-loosening marks.
