Description

PERKINS INDUSTRIAL:
• Perkins 1103C-33/1103C-33T/1104C-44/1104C-44T 1104C/D 4.4L (2000-2026)

CATERPILLAR EQUIPMENT:
• Caterpillar E320GC CAT C4.4 (Perkins 1104D-E44TA equivalent) (2000-2026)


IMPORTANT:
34-tooth spur crankshaft gear for Perkins 1103C/1104C/1104D engines (4.4L). Cat equivalent: 3054C / C4.4. This gear drives the entire timing gear train — it is the master timing component. Failure or wear causes ALL dependent systems to lose timing.

Used in Cat backhoe loaders (416F-444F), excavators (312-320), and numerous industrial OEMs. The Perkins 1100 series is one of the most widely OEM-sourced modern diesel engines. When replacing, all timing marks MUST be aligned — one tooth off can cause valve-to-piston contact. Replace the front seal and inspect all mating gears for wear.

⚠️ Master timing gear. Align ALL timing marks per service manual before starting engine.
