Oberstar Posted April 1, 2018 Report Share Posted April 1, 2018 Gents, I'm applying a new water pump to my D24 motor, installed into a WC52 3/4T truck. My WC manual shows (3) studs utilized. May I ask what length bolts you used in your block, and where did you place them? Looking at the front of the motor, I plan on using a stud at the 3 o'clock position, but which lengths to use at the 9 and 6? Thanks! Got a good price on a Gates, then learned it was Chinese...

desoto1939 Posted April 4, 2018 Report Share Posted April 4, 2018 With the use of the stud there would be a nut on the end to hold the body of the water pump onto the front of the engine block. So first i would measue how deep each hole is and then figure the thickness of a nut to put on the exposed end then figure at least anothe 1/2 inch to thread into the front of the block. I know the older engine used three studs and the newer engines used two studs and a bolt to thread and hold the wp to the block. Just looked inmy Desoto 1936-42 masterparts book and this is what they state are the measurements is for 1936-1940 3/8 inch -16-24 x 2 7/16 inches, 3/8-16-24 x 2 5/16 inches and 3/8 -16-24 x 1 11/16 inches. Hope this helps you witht he studs and lengths. Rich Hartung desoto1939@aol.com Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted April 4, 2018 Report Share Posted April 4, 2018 If you put a stud in will you still be able to service/replace the water pump with out removing the radiator? Quote Link to comment Share on other sites More sharing options...
desoto1939 Posted April 4, 2018 Report Share Posted April 4, 2018 on my 39 desoto I can pull the waterpump without removing the radiator. i have to remove the fanblade assembly and the pully then the entire unit is unbolted and the unit slides off the three studs and I lift it right out of the engine compartment. This is all based on the original studs and the information that I provided based on my 1936-42 desoto Master parts catalog.

Oberstar Posted April 5, 2018 Author Report Share Posted April 5, 2018 Thanks for the replies, guys- In an effort to be aware of changing the water pump in the future, I utilized a stud at the 3 position, but new bolts and washers at the 6 and 9. I chased the threads and cleaned the bolts- but how are you expected to seal the threads that go into the water jacket, but also keep the bolts from seizing?
