Description

CATERPILLAR EXCAVATORS:
• Caterpillar 315/315B/315C/317B Cat 3046 5.0L Diesel (1995-2010)
• Caterpillar 318B Cat 3046 5.0L Diesel (1995-2010)

CATERPILLAR TRACK LOADERS:
• Caterpillar 933/933C/939/939C Cat 3046 5.0L Diesel (1995-2010)

CATERPILLAR TRACK-TYPE TRACTORS:

• Caterpillar D5C/D5G Cat 3046 5.0L Diesel (2000-2014)


IMPORTANT:
Identical pump to Cat 113-1141 — same part, different OEM number. Fits Cat 3044/3046 engines (Mitsubishi S4S under Cat branding). If your dealer quotes one number and you find the other, they are interchangeable.

Used in Cat 315-series excavators, 933/939 track loaders, and various skid steers. The 3044 (3.3L) and 3046 (5.0L) share this pump despite different displacement — same pump interface. Failure symptoms: low hot idle pressure, metallic whine increasing with RPM. Gerotor type, flange mounted. Clean pickup screen and inspect housing bore before installing.

⚠️ Same as 113-1141. Fits Cat 3044/3046 (Mitsubishi S4S) — NOT Cat 3054.
