PROCEDURE:

 

1.  Locate the HWH identification tag on the SpaceMaker mechanism to get the correct mechanism part number.

 

2.  Find the correct SpaceMaker mechanism part number in the left column below.

 

3.  Refer to the listed HWH Parts Manual Page for general replacement parts information and item number arrangements.

 

4.  Note that two-cylinder mechanisms with a synchronizing cylinder have two part numbers.  One number is for the left assembly and one is for the right assembly.  If the mechanism assembly originally had one number, that number is listed with the new numbers.
