1650 inj pump

756puller · Jun 9, 2021

Had a guy talk to me about his 1650
diesel. He said every once in a while the
banjo bolts on the injector lines come
loose. I know I need to install new copper
washers around the Injection pump lines.
Could I also used some blue locktight to
help the bolts from coming loose or do I
need to send the pump off for a head?

I use the mild steel line washers, CAV 5936 332C. I've never had a bolt come loose with these washers, seat the bolt, then go 1/2 turn more and you're done. DO NOT use sealer on the bolt threads, that's asking for trouble if sealer gets into the injectors..

Would that cav number be an agco part number or where could I source them from?

I have them on hand, E-mail is open on Classic view.

Dieseltech: What clamps do you prefer on the T for the fuel return lines? Also, use only 1 or on every connection? (3 connections on each T)

One spring clamp at injector, with new Tees and good lines no more clamps should be needed. I have seen small gas line screw clamps used though..
