This kit contains essential parts for routine maintenance of your Universal Diesel engine that uses the early style Sherwood water pump. The kit includes two oil filters and two fuel filters (one of each for now and another for a spare), a fuel pump filter and gasket, and a new impeller and gasket for your water pump. The only thing you need to supply is the oil.
The difference between each of the Diesel Engine Spares Kits is the parts included for the water pump and the lube oil filter (The 5411 uses a different oil filter). To identify which water pump you have, refer to the additional picture below.
This kit is for the Universal 5411 Diesel engine installed on several Catalina 27s and Catalina 30s.
