[AT] Allis Chalmers ED40 injector pipes

[James Peck]

Parker makes fittings specifically for pressurized diesel. The question is the thread standard used back then might not be available. Does anyone know the thread system used in the early 50s in the UK for fuel injection? Might be BSP.

[link] Fittings: Available in inch and metric sizes covering SAE, BSP, DIN, GAZ, JIS and ISO thread configurations, manufactured from steel, stainless steel, brass, aluminum, nylon and thermoplastic.

Cecil Bearden AT List member, Oklahoma farmer, and Professional Engineer (crbearden at copper.net); IIRC the tube fittings on the injectors and the pump are threaded into the pump casting and the injectors to adapt them to the tubing.  If you could determine the thread in the pump and injectors, then a hydraulic fitting could be used for the lines. Just a thought Cecil

John Maddock AT List Member (agtronixjv at southcom.com.au); Thanks James.  I'll pass this info on to Guy.

 With a thread gauge you could determine the size and pitch of all the  ports. With an on-line catalog (Parker is one suggestion) you could  identify all the fittings you need. Parker catalogs usually have info  on making up tube assemblies. You would also need to order tubing and  a tube bender. I bet you can bend up the set of tubes yourself. The  steel tubing is the only thing that is difficult to ship. You could maybe  pick that up at a local fluid power distributor. If you gave your  list of parts to a local fluid power distributor they could probably  cross it over to the similar items in the brands they carry.
