Tools I should buy.

[ByronRACE]

Guys, what tools should I buy for servicing this 12V cummins?

I have a valve spring compressor and have used it to change my springs to +60's for use with my exh. brake.

I see that there's a J shaped injection pump wrench I may need someday.

I see that there's a baring tool; that looks useful.

What kind of wrench do you guys use to get the lines off the back of the injection pump? I wanted to put a wrench on each one of these and check torque... but found that impossible. I can't imagine you remove all of them to get to the back ones...that seems crazy.

Any other tools?

For rolling the engine over, I find turning the nut on the alternator pulley even more convenient than a barring tool.

That seemed to work really well when I first got this engine. Then, I eliminated the AC, changed the belt to the non-AC belt, and now it doesn't work as well. Or, maybe it began when I put the +60lb valve springs in. Not sure, but now I can't reliably turn it over that way. It slips. The belt probably isn't as grippy as the old one.

I like to use the alternator also, over the barring tool. When I first got my pickup it would just slip the belt, but a new belt fixed that.

I used a torch to make a 13mm wrench for the IP bolts. Not pretty, but very cheap and works good.

I've always just used a 17mm wrench for the lines on the pump. I think a "Stubby" wrench works a little better for getting to the lines. Either way it's a pretty big pain.

Hmmm, it seems like there should be a better 17mm wrench solution for the lines. Cummins lists a torque spec for those fittings. Now how on earth could you use a torque wrench?

You'd use the weirdo crows foot wrench that is designed for this and a torque wrench.

That socket/crows foot is over 100$ on the snap on truck......I'll use a stubby and regular wrench

You'll need a backup wrench to hold the delivery-valve bodies while messing with the injector feed-lines.

These are what snapon offers as a service set

That weirdo socket is in the center,under the feeler gauge

Bc I've never used a wrench to hold the delivery while tightening, how tight are you going

I use a regular wrench and just feed it between the lines, it goes in, you just have to find the spot. I've never seen 1/2 of those tools. I turn the engine over with a 15mm on the balancer bolts. I have heard you can take a piece of 2" square tube and weld it to a socket and it will fit over the balancer bolts to turn it over.

It's just the way it works around my house, you go to loosen a injector feed-line nut, the DV loosens instead. Of course, if you don't anticipate it, you risk twisting a feed-line. Same thing tightening except I figure one might tweak a DV holder.

OK, these.

Great. I'll add them to my Christmas list.
