Pump drive cam 12,75

The pump drive cam for THERM 1017 is part of the drive transmission mechanism in an industrial washer’s pump system. It supports correct operation of the drive assembly and repeatable motion in the pump section, so its condition directly affects smooth running and the service life of cooperating components.

MPN / reference: 404601275
Weight: 0.53 kg
Dimensions / size: 9 × 4.1 × 9 cm

APPLICATION

Used in industrial washer service work, including:

• repair of the pump drive mechanism in THERM 1017 units,
• replacement of worn drive transmission parts during pump overhaul,
• eliminating play and uneven operation caused by cam wear,
• rebuilding the assembly after mechanical failure or overload operation.

SYMPTOMS - WHEN IT’S WORTH REPLACING

Typical signs of cam wear or damage:

• unusual noises from the pump drive area (knocking, rubbing), increasing under load,
• noticeable play in the mechanism after disassembly or during inspection,
• uneven pump operation (vibration/rough running) after ruling out hydraulic causes,
• visible wear on contact surfaces (polishing, scoring, scratches),
• recurring issues after earlier repairs when the worn cam was left in place.

HOW TO CHOOSE THE RIGHT PART

Select based on the reference and comparison with the removed part:

• by manufacturer MPN / reference: 404601275,
• by application designation: THERM 1017,
• by comparing to the removed component: verify cam geometry, dimensions, and how it seats in the assembly.

Accurate fit is critical - drive parts operate within tight tolerances, and an incorrect match can accelerate wear of cooperating components.

COMPATIBILITY

Part described as a pump drive cam for THERM 1017. Confirm compatibility by MPN 404601275 and the unit/pump parts list or service documentation. Do not select only by the description “cam for THERM” without verifying the reference.

[faq]

Do vibration and noise always mean the drive cam is worn?|Not always. Similar symptoms can also come from bearings, play in other drive parts, or assembly issues. However, if inspection shows scoring and play on the cam, it’s a common cause of degraded drive operation.
How do I confirm this cam fits my THERM 1017?|Check MPN 404601275 in the parts list/service documentation and compare the geometry and dimensions with the removed part.
Can I use an aftermarket replacement for this drive part?|Only if geometry, dimensions, and intended use match exactly. For drive components, tolerances and manufacturing quality are critical - an incorrect part can accelerate wear in the pump assembly, so use the MPN and specification as your reference.
