China Wholesale for TU-1F90 thermal wax actuator for automobile engine thermostat manufacturers for Borussia Dortmund Importers Detail:
1. Operation Principle
The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
2. Characteristic
(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.
(2)Temperature control is reliable and nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.Main Technical Parameters
(1)Handspike’s height may be confirmed by drawing and technical parameters
(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.
(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

The lift function of my bobcat stopped working. The left joystick was blinking 5 blinks on the left LED, and all the service manual said was to replace the AHC actuator. Once I fixed it, the left joystick was blinking 2 blinks on the left joystick and the service manual said to calibrate actuator, which I did to 1.72V, although I didn’t realize this until I was finished making the video. Note that calibration of the actuator means that the actuator is removed from the machine, disassembled and the potentiometer gear rotated so the output voltage reads 1.72V when the actuator is 0.114″ into the end.
Some pictures and video of fixing a bobcat 863F lift tilt actuator with AHC – advanced hand controls. This bobcat has a metal cased AHC controller. The machines with the plastic case may be different. The video also shows how to replace the spool seal on the lift actuator. Note that I was not able to easily slide the spool out of the back of the hydraulic manifold (it was running into a hard hydraulic line), so I only changed the front seal. The rear seal wasn’t leaking, but I’m sure it will start now that I didn’t change it!
The Bobcat AHC actuator part number is 7104842 for the old style AHC controller.
The globe motor part number located inside the actuator is 403A851
The newer actuator part number is 7101672 which is for use in machines that have a plastic AHC controller housing. That actuator sounds like it’s the same, but when assembled they set the position of the linear actuator to be flush with the end of the actuator instead of inset 0.114″ when the potentiometer voltage reads 1.72V (thanks to Ed for this info).
I see that these two types of actuators are used on a number of models:
