Problem
The existing 7C4714 Adapter in the 9Y4888 Emergency Oil Connection Group may not have a hole on certain 3508, 3512, and 3516 Marine and Generator Set Engines. With no hole in the adapter, oil can not be pumped through the emergency oil connection group. A new adapter needs to be installed to replace the existing adapter in the front of the oil pan.
