Available Models
MTF Farm-Duty T-Frame Single-Phase Motors Features and Specifications

IronHorse® single-phase farm-duty motors are available
from 2hp to 5hp. All models have a TEFC housing (steel
frame with iron end bells) that is fully gasketed for use in
dirty environments. All motors are NEMA L design.
All models include a class-10 manual-reset locked-rotor
thermal protector (motor thermal overload protection must
be provided separately).
We recommend disconnecting power to the motor
before reseting the thermal protector. Do not
reset more than twice in succession. The motor
must cool to 40°C (104°F) before a third reset.

Chapter 1: Getting Started

Reshipping
If an IronHorse motor needs to be reshipped from the initial shipping point, the following
procedures should be followed to protect the motor from damage.
1) If the original packaging is to be used for reshipment, inspect the packaging for previous
shipping damage and repackage if necessary. Take care to protect the motor body, fan
cover and shaft.
2) I t is a good idea to bolt the motor to a platform that fits securely in the bottom of the
shipping crate or box. This helps prevent the motor from shifting during transport and thus
protects the bearings from damage.
3) A
 shaft lock device should be installed on motors from 100 to 300 hp prior to shipment.
The shaft lock helps prevent bearing damage.
4) M
 otors should only be lifted by the the eyebolt(s) provided on the motor. When lifting
motors with more than one eyebolt, use every bolt provided.

Long Term Storage
The following preventative measures should be taken when storing IronHorse motors for a long
period of time.

 tore motors in a controlled temperature, dry atmosphere free of excess dirt, dust and
airborne particles.
2) Rotate the motor shaft every sixty days to prevent hardening of the bearing grease.
3) W
 arehoused motors should have the bearing grease purged and replaced every six months.
Use only Mobil POLYREX® EM Polyurea grease.
