Tuthill 2CB1B534-56 NEMA 56C Motor Adapter Bracket for 2C Pumps
The Tuthill 2CB1B534-56 is a genuine motor adapter bracket for Tuthill 2C Series gear pumps driven by a NEMA 56C face motor. The adapter bracket registers the pump on the face of the motor, which takes coupling alignment out of the installation entirely. It is a straightforward casting, but it is the part that decides whether the pump sits square and stays that way.
A C face adapter takes the alignment out of the installation, because the pump registers on the motor face rather than on a base plate. Tuthill publishes adapters across the NEMA range from 56C up to 326TC, and the frame size in the suffix has to match the motor exactly. Shim the mount rather than pulling it down onto an uneven surface. Drawing a foot flat against a warped base distorts the pump housing, and that shows up as noise and as bearing wear rather than as an obvious fault.

Frequently Asked Questions
Q: Is this included with the pump?
No. Mounting feet and adapters are listed options and are ordered separately from the pump end.
Q: Will a foot from another pump size fit?
No. The feet run in size groups and the hole pattern changes with the frame, so the foot has to match the pump size.
Q: Does using a foot change the pump rating?
No. It changes how the pump is supported, not what it can do.
Q: What is the difference between the LA and LE patterns?
The flange. LA pumps use a two bolt flange and LE pumps use a three bolt flange, so their feet are not interchangeable.
