Lube it with silicone paste, and install the seal, LIP TOWARDS COMPRESSOR, using a deep socket. It should press in smoothly by hand.
Should look like this:
Remove the thimble and install the snap-ring. Sealing complete!
Clean and inspect the electromagnet coil. No cracks or broken pins in the connector!
Set it on the compressor, lining the connector up with the flat spot where it was originally aligned.
Drive it down, using a punch or extension.
