Disclaimer:
If you are using an aftermarket replacement part number for the replacement of an OEM part number, the port and clamp band angles may need to be rotated and the push rod may need to be cut to length. In addition, our aftermarket part numbers come standard with no yoke assembly.
Replacement parts may differ for production part numbers. If you are uncertain that the replacement part listed will work in your unit, please contact us via Live Chat or by calling customer service at 1-800-527-1534 Ext. 6021.
