I don't know what the differences are, most people talk as if they are the same pump. 15hp difference might just be a differente plate position. Or maybe timing differences between the two. Timing chart lists 160/175 pumps the same, except for emissions 160 pumps.

Tate, I have a 215HP, 913 pump we can take a peek at. Find someone with a 160 pump and we can compare. Sounds like a good way to spend an afternoon. Be a good way to document whats a stock unmessed around 913 pump. Anybody know where we can find instructions or diagrams for the pump? You probably have to be licenced in Bosch repairs. I've been thinking about doing a rebuild on the 913 anyways.

How do you adjust the timing on the 12v? Is the timing static or changes with engine rpm? I read the dodgeorg.com, still hard to follow. I'm a dummy on these engines.

Mike...Do you have one or two 913 pumps??

Mike Holmen

So far only one, why? What did I just volunteer for?

Diesel Dave2

That you maybe starting a p-pump collection......You have more turbos than any of us...

The P7100 pump are tuffer to find and collect. I was one of the computer guys until I saw this mechanical stuff. I like the engineering in this 12v engine. I think you could build one bad truck out of one of these 12v engines. Wrap a 3000 lbs body around it. Dana 80 for a rear. 33X14in slicks. It would be a fun ride and use for a daily driver after.

I've got a 175 pump laying around, but its not exactly something I want to take apart given that its a fresh rebuild. Just rotating the barrels will affect the fueling. Messing with the governor is an easy way to mess something up and forget about until you go to run it. Pull the AFC and plate out, pull off a DV holder and have a look at the plungers and DV's. You can pull off the rack plug to measure travel too if so inclined. Thats as far as I went, and as far as I would go.

To time, you change the position of the pump shaft on the pump gear. Timing is static, but like I said earlier, the 215 have retard notches in them that will retard timing with more rack travel. The rest of the pumps are flat top plungers and won't do this. That also allows the 215's a bit more fill time, in addition to the cam design.

I have a 913 that will be overhauled. You think we could take a look at it without wrecking it? Most will be replace with different stuff anyways. I'm game. If you want to use a plasma torch on it I might have to think twice on that but ripping it apart to see whats inside is ok with me. Mine is just a core. I'm am ok with spare with cutting up T04 HX-40 turbine casing, P7100, 913 nope.

-Cutting up a good 12v head is still warm and fuzzy
-Cutting up a bad cracked 24v head, can I go first.

All this yap about different pumps... do some research on the lil' 160 pump... It'll out perform anything when done right...

Tate

Got any info to share? I haven't traded my 175 pump for a 215 because I've heard that as well, so I'd love to know more.

Mike Holmen

Tate, which pump do you have installed in the dually? Only one way to find out which is better. You got those twins almost done. Big 24v sticks. Have to see how good the clutch is after all.
