REASSEMBLY PROCEDURES FOR REPLACING CE HOUSING OR RECONDITIONING HOUSING WITH SERVICE PARTS
If reconditioning the CE housing using the service package to replace the wick, cup and bushing, follow below steps. If CE housing
assembly is being replaced, continue to step 4.
1. Soak new wick in SAE20 weight oil for several hours to allow the oil to penetrate and install into the housing.
2. Align the cup with the wick hole, open end down, and tap it into place until it is flush with the housing. It is best to use a deep well
socket or similar device about the same size as the outside diameter of the wick cap. Strike it with a hammer until the cup top is flush
with the casting.
3. Install the CE housing bushing. This requires using an arbor press or a special tool. The recommended special tool is like a large
pin punch which has about the same outside diameter as the armature shaft for that end with a shoulder on it about the same size
outside diameter as the bushing.
Install the o'ring onto the frame groove.

Install the square fiber insulator and fiber washer onto the ground stud. In some Grounded 37MT & 41NT starters it won't be
