The only place that would possibly have the motor shroud would be Precor and they may say obsolete no longer available. This particular model # is not familiar to me since the common numbers on the older treadmills are 905e, 9.1, 9.17. 9.2 etc I assuming this was not intended to be sold in the USA.. I Suggest going to Precor's website and get the appropriate phone # to call.

The incline on our Precor c964i is stuck in a high position (approx. 10% incline). Other than being on a high incline, the treadmill seems to be working fine.

Hi There,

Precor uses a pair of Triacs to drive the lift up and down. These triacs live on the lower board but are driven by the upper console commands via a serial link between the upper and lower. Most precor lift issues we see are related to the lower board but with Precor it could be an upper board or the CPU Chip that resides on the lower board or a failed Triac. Good Luck

Where can I find a used lift motor for a Precor C966I treadmill? Part # on the motor is 6182A-1705080-01

Replacement Parts for Fitness Exercise Equipment at SPORTSMITH

I am not sure where you can find a used one, but I can find a couple of new options for you. Depending on your machine, there are two different motors available. One is for a 220V machine and the other is for 110V machine. I will post links to both.

How do I solve Error 42?

Precor Error Code 42 Error Code: 42 Manufacturer: Precor
Model: All Models
Error Description: Error 42, Lift Position Value Out of Range. Error 42 is displayed when the lift position reported by the lift position potentiometer is found to be outside its set limits.
If an Error 42 has occurred, it is important to know the physical position of the lift when the error occurred. It is possible the lift is physically out of range or jammed. In this case, the Error 42 is a secondary symptom and the issue should be approached as an Error 40. Possible Reason:
  1. Bad or intermittent connection in the lift motor controller.
  2. The lift motor requires calibration.
  3. The lift motor potentiometer is bad.
  4. The lower PCA to upper PCA cable is bad.
  5. The lower PCA is bad.
  6. The upper PCA is bad.
Recommended Action:
  1. Intermittent connections can be difficult to locate. If the Error 42 condition is intermittent, a connection issue is probably the cause. This is definitely true if the Error 42 occurred while the lift was within its normal physical range. Inspect the lift potentiometer connector and repair connection if necessary. If the intermittent connection cannot be found or corrected, replace the lift motor. A lift calibration number of 0 or 255 indicates an open or shorted potentiometer connection. This means the problem could be anywhere between the lift motor and the upper PCA. Typically it can be identified and tracked using an ohmmeter.
  2. Using the appropriate service manual for the unit being tested, refer to the lift calibration procedure. If the information in the service manual doesn't match the lift position/physical lift position of the unit, recalibrate the lift motor. [Something caused the lift motor to be out of calibration. Investigate for cause and correct. Simply recalibrating the lift motor will not solve the problem.]
  3. If the lift calibration number is not 0 or 255 and does not change when the lift motor turns, replace the lift motor.
  4. Check continuity of the interconnect cable or swap with a known good interconnect cable to verify if cable is bad.
  5. Swap the lower PCA with a known good lower PCA to verify if the lower PCA is bad.
  6. Swap the upper PCA with a know good upper PCA to verify if the upper PCA is bad.

Where can I find a Precor 9.21 treadmill motor cover?

Do you know which version of the Precor 9.21 you have? There are a few different versions you can view here. Click on your version to view the parts list and look for "Cover, Motor" or "Motor Cover".

For instance, if you have the 9.21 (AYYZ), the proper motor cover is this part #5019749

However, this part #5005569 is listed as the proper motor cover for the 9.21 (F5), 9.21i (2X), 9.21s (F6), 9.21si (2Y), and a couple others. Make sure you have matched up your exact model number with the motor cover you need so do you not order the wrong part.
