The BT2-4011 Coyote Series F Control Knob is used on compatible mobile HVAC control panels.
It provides an operator knob for adjusting a control function.
This knob cross references with Coyote part number 01-1055.
The drawing also lists DF51 as a related reference.
As a result, it is a useful replacement knob for compatible Coyote Series F A/C and heater controls.
Function and Design
A control knob gives the operator a simple way to adjust an HVAC switch or control.
It can help restore normal control use when the original knob is missing, worn, or damaged.
The drawing lists the shaft opening as 0.252 in. x 0.160 in. +/- 0.003 in.
It also notes that a 0.250 spring diameter metric spring is available.
Because knob fitment depends on shaft style, shaft size, spring style, and orientation, compare your current knob before ordering.
Durability and Layout
The BT2-4011 Coyote control knob is designed for mobile HVAC use.
Cab controls often face repeated use, vibration, and temperature changes.
The drawing shows a compact round-front knob with a raised grip area.
It also includes side and top dimensions to help confirm fitment.
Always verify the knob profile and control shaft before installation.
Installation
Install this knob by aligning it with the control shaft.
Then press or fit it into place according to the control design.
Before installation, confirm the shaft size, spring retention style, knob orientation, and control panel layout.
Do not force the knob if the shaft or opening does not match.
