4600 SU injector pump installation - any special issues?

davidl1632 · Oct 6, 2016

The seal blew on the injector pump on my buddy's 1979 4600 SU. Pump is being rebuilt, and when we put it back, are there any special issues we need to know to get it installed correctly? Also I had the injectors tested and they're OK...how tight do I have to torque them down? Your knowledge and experience is always appreciated, thank you!

Just put the pump back in place on the dowel on the gear, bolt the gear on (and don't lose the bolts down the rabbit hole) and set the pump to 1/2 deg clockwise form '0' on the mounting plate. As long as you didn't remove the drive gear you should be fine.
Injectors... I think call for 20 ft-lb or something. A twist of the wrist is enough. Less is more or you'll break the ears off.
