Jabsco Perkins 2436

[nautifish]

Hi all. I have taken my jabsco pump off my Perkins 4236 for a rebuild as it's leaking. No numbers on pump. I've lost 2 of the 6 end plate screws in the bilge. Does anyone know what the thread and size of the screws are as I want to change them for Allen key heads to make life easier as its way down the bottom of the engine for future impella changes etc I'm hoping the thread is metric 4mm
Thanks for any advice really appreciate it.

Why dont you just measure the existing screws?

With small screws I get a known threaded screw and try it by hand rather than risking the thread gauge and my eyesight on a fine thread.
