Need help identifying a Cat 3406

Thanks for the help guys! Will be starting the rebuild later today or tomorrow and will post up the photos as we make progress.

There are cruise switches on my dash and I'm pretty sure they don't work. After crawling around on the motor the last several days I really don't see how it could work with the present setup.

 

Quick question. Ready to order a new set of injectors for this engine, which injectors are correct since it's got mechanical injection? Regular 3406B injectors?

 

Gotcha, so regular factory spec 3406C injectors it is. Thanks!

 

Still working on the tear down and making great progress except for the 7W3906 fuel pump assembly.

As far as I can tell I've got all of the bolts out of the pump that mate it to the block and the front cover of the engine. The pump will wiggle and move around but we can't seem to get it out by more than 1/4" or so.







Does the hub on the front side of the assembly need to come off in order for the fuel pump to come out?

 

Is there a spring or anything under high tension that I need to be worried about before disassembling the hub?
