Singer 112W 115 Knee lifter installation

[DMH]

Hello,  I'm looking for help with the knee lifter placement for my recently purchased Singer 112W115 double needle machine.  I purchased a table top and had some difficulty finding mounts for the machine head, but finally got that resolved (I think).  I installed the oil drip pan, motor and belt.  I purchased a knee lift (photo attached) and lined it up with the space in the oil drip pan, but when I try to engage the knee lifter it does nothing.  What am I missing or doing wrong? Where should the knee lifter make contact with the machine?

please post pictures of your machine from the rear and when tilt back from the underside and how you have installed the foot lifter.

I cannot see how you mounted the lifter but what I can see is that the roller (224413) on the lifting rod (240550) is missing (isn´t it?) and the orientation of the "tab" is wrong. It has to be like the red frame IMO the longer end has to face right. Thats what I can tell the rest is trial and error where you put the foot lifter assy.

Thanks for the information.  I will make the adjustment and see how it goes.  I really appreciate your assistance.
