Howdy all,

This is my first post here. I have a Kenmore 363.157250 dishwasher that needs the lower spray arm assembly rebuilt. I have ordered all the parts to include: Lower spray arm, Lip seal, split ring etc. My question is the following:
1. How do you install the lip seal? Does the gear seperate from the hub so the seal can be installed? The lip seal is 561 on the drawing.
2. What is the purpose of the split ring? This appears to be a nylon washer about 2" in diameter with a small section cut out of it. In other words it is not a complete circle. This split ring is installed between the spray arm and the power adapter. Water is gushing out of this area. This is item 546 on the drawing. Is it simply sandwiched between part 501 (Spray arm) and 546 (Power adapter)?

I have noticed a lot of water gushing out below the spray arm thus reducing the effectiveness of the spray arm.

Any help is appreciated and thanks in advance.
