1956 caterpillar d2 5u going direct start

What do you do with pony exhaust just plug with metal plate ? And big air intake goes to original pony exhaust chamber. If that's plugged ok ? Anyone that got a 1956or 57 that has original d2 with factory 24 volt starter system if get time please contact me Brian 651 307 7338

yes. the pilot engine exhausts via a pipe in the intake manifold that pipe can rust out. especially if it didnt have a rain flap fitted or wasnt kept covered when not in use. (old spin on oil/fuel filters make great covers they are rounded on the end so naturally shed water. just cut the mounting flange off and pull the guts out)

that's why it would also be a good idea to thread a bung into the pilot engine exhaust pipe so you cant dust the motor. or unbolt the riser pipe from the manifold and blank both ends of the main engine intake manifold.

there is coolant galleries to blank off in the head and the bell housing if you remove the pilot engine. most people do as they mount the batteries in that location. a steel plate coated with devcon metal fix epoxy and paper gasket is all you need. (the devcon helps with corrosion resistance)

if you can find em there is factory direct electric start cyl heads that had positions for glow plugs this makes starting easier.

i'm using a manifold heater plug on my d4

Hey thanks yes goings to plug all exhaust openings. devcon metal fix epoxy is the way to go

Been looking at little worried because bolt dow are a ways from coolant return

You just sealer and gasket will do?

Thanks very much. Thers not any manuals that covers that you know of ?

yes just use a paper gasket and a dressing such as form a gasket n03 or stag jointing paste. and you can get it apart later if needed use a little heat or methylated spirits both products are soluble in metho.
