Engine Parts supplier and Oil Cooler Part Numbers

As my oil cooler started to leak coolant, I was in need to find the correct gaskets and packing o-rings. After consuting with a local heavy diesel shop that knows their stuff, they cross-referenced our LDT-465 engine to a Hercules D4800T (T for turbo). At $2.90 for each gasket (oil cooler to housing and oil cooler cover) and $2.00 for each o-ring, I was out the door pretty cheap with new parts (not gaskets/orings from the 60's and 70's).

Hercules Distributors

That link will show you suppliers in your area.

Here are the part numbers as follows:

(1) Oil cooler to housing: HER375098-00
(1) Oil cooler cover: HER375101-00
(2) O-rings/packing: HER 207388-00

Hope that helps, I know I was in a pickle! The guys at the shop even let me borrow a manual for the engine... great information!
