IDI Injector replacement

[IDI87]

Has anyone done a full write up of the replacement procedure for the injectors? I want to do the ones in my 6.9 and the 7.3 I got last night. I've been surfing the forum but haven't found anything yet. And is there one for the glow plugs? The 7.3 system isn't working right now.

For the glow plugs what are you doing? Are you replacing just the plugs or are you trying to diagnose why they aren’t working?

I'm thinking that the glow plugs are shot. But I need to diagnose the system. The guy I bought it from was using ether to start it. And I am not an ether fan. Thankfully he only used a tiny amount and not a huge shot like most people.

I'll post a picture of what I'm working with. It also needs some rewiring, most people don't shall we say have a lot of skill in that department......

Helpful hint: If you're going to replace the injectors and glow plugs, replace the glow plugs while the injectors are out. That way you could move the injector lines slightly if (where) they are in the way. I like to use a 1/4" drive ratchet, swivel, and about a 6" to 8" extension. That makes it easier to get in to them especially when the injector lines are attached to the injectors. You'll also need a 3/8" deep socket for this.

Good idea. This is actually my biggest work truck so down time in the future will get expensive.

Every now and again people will pull out half an injector. The bottom half stays in the hole. It's not time to panic, though, there is a set method to remove that bottom half. If you have that problem don't immediately do something drastic. Post and ask. It can be gotten out without any damage being done.

! No that would just send slag down into your precup and then on into your cylinder where it wouldn't do the piston any favors. Good thing you were just kidding.

Lol. I sadly know a few that would do that.

There's some out there that would try.
