I got some performance tips from a Cummins mechanic. The first two things were to set the valve lash 2 thousands tighter. 18 thousands for exhaust 8 for intake. We advanced the timing a couple of degrees. Those helped but next came a Banks exhaust and 16cm turbo housing. The biggest gains were the fuel metering pin and the 3200 rpm Governor spring. The 5.9 B engines were designed for industrial applications and so the Governor starts to cut back fuel delivery when it gets up close to the designed maximum rpm. You’re making less HP and torque at 2600 rpm than at 16-1800 rpm. Ran the early 250hp 5.9 Bs in duel marine applications and. They were OK but Smokey. When the 300hp version was released Cummins said they were too strong for us. I looked at the specifications and saw the only difference was a higher pressure fuel system and 200 more rpm on the top end. 2600 vs 2800. The weight was the same. That’s what went into the next boat and it made a world of difference. Also a cleaner running engine smoke wise. As subsequent models came out the horsepower continued to climb. RD

[@txmuddigger]

You autta get you a long allen ball tip socket for that back bolt. It'd be handy if you're doing em all the time for sure.

[@decentgarage]

Yeah, i've been meaning to get one.

[@ryanostmann2445]

Thanks again Tim for a great video for us hobbyist mechanics. A problem I ran into, that I hadn’t realized, was someone previously had done the “1/8 in timing bump” and my pump was rotated towards the cylinder head allowing for zero room to even see the back Allen cover bolt. after hours of scratching my head and figuring out how to loosen the pump from the timing case I was able to get to it. Unfortunately at this point I began rushing and missed your warning about the “top hat spring” …. It went flying…. I was actually able to make one from a pen spring and it seems to be working just fine for now until my replacement spring comes in the mail.

[@decentgarage]

Oh no! Well I'm glad you figured out a solution

[@MrACV24]

A trick I use to break free Allen bolts is to use a Crescent Wrench. Stick the Allen Wrench end into the hole in the side of the Crescent. It won't slip out, you have a lot of leverage, and you can use your free hand to keep downward pressure on the Allen Wrench so it won't strip.

[@decentgarage]

That's a perfect idea! Thanks for the input!

[@pdb4382]

I'm midway through this process. One difference with a manual transmission the low pressure supply line from the fuel filter crosses over the throttle assembly close enough that it has to be removed to pull the assembly up off the shaft. On an automatic it routes around the throttle position sensor. You'll need a 14mm for the top nut and a 17mm for the bottom and avoid twisting the fuel line. I'm waiting on a crowfoot flare nut set to be delivered so I can continue.

[@decentgarage]

Interesting! I didn't know there was a different in that line between auto and manual. The more you know. ⭐

[@pdb4382]

@@decentgarage Hours of research for a replacement line for when I inevitably twist and kink the currently installed one leads me to believe mine *might* be a one-off replacement or non-Cummins part. The only OEM replacements I could track down route around the throttle assembly as yours does in the video. Not sure. Thanks again.

Love your videos my truck is a 1993 dually with a 5 speed. Want to end up putting around 300-400 hp at my rear wheels. What I want to put on my truck is either 5x12 or 5x14 ducky injectors. 3200 gov spring THD fuel pin, intercooler upgrade kit and BHAF intake kit and either a hx35 wastegated or a 60 mm turbo upgrade. I can get everything off of the Hungary diesel except the turbos and the injectors and will be using ur code.

[@decentgarage]

Call Eric at the hungry diesel. He sells turbos and injectors as well. Sometimes they are not listed on the site though. He'll hook you up

[@jond1536]

He should also advise to change the Throttle Shaft O-Ring, as if yours is like mine that O-ring has been on that shaft for 40 years (1991 pre 1991.5). You can purchase the expensive ones or get the Harborfreight O-ring kit (must be over a hundred O-rings in that kit) red and blue boxes for about 10.00 each one metric the other inch. I hate leaks and don't have many. Tappet cover gasket, lots of parts have to come off to get to that. I will say, decent Garage has lots of GREAT videos of how to do things. Thanks for all your videos, my next project will be Ball Joints. There is also a way to reassemble without moving the power screw. using a piece of wire to hold the lever forward against the spring pressure. when you put the top back on. it works just need to be careful and not in a hurry and do not force anything it goes in real easy. That way I didn't have to worry about a run-a-way and once I figured out the indexing, it started right up and of course the indexing was off a tooth. fixed that and no issues. Again thank you for the videos they are so very helpful (and I know quite a bit about these old trucks) never too late to learn new stuff

Hey, I have a problem! I did everything exactly like you said; I got a BD spring and the instructions say to unscrew the max fuel screw until you can see the O ring before removing the top of the pump.

I even put a jumper wire between the FSS and the positive terminal on the battery to make sure the solenoid is open. Is it possible there's air in the lines? Any help appreciated.

[@decentgarage]

Could be air in the lines but I've never had that issue when doing this. Make sure theax fuel screw was backed out enough so that it isn't protruding in to the pump top. This makes it clear the fulcrum lever. I would also triple check indexing. Also, did you turn the max fuel screw back in to where it was prior to pulling the pump top?

@@mementomori2353 the 3800 spring is stiffer and slightly longer. Some people trim it so it's the same length as the stock or 3200 spring and reindex back to the second mark.

[@decentgarage]

Throttle indexing is off.

[@decentgarage]

Make sure to pull up on the throttle shaft when you are lining the splines up on the throttle lever.

[@laynewade6700]

@@decentgarage you are correct. This is the second time I've aligned it and it keeps jumping back 2 dashes. Will try pulling up!

@@laynewade6700 i can be a bugger but you'll get it!

[@laynewade6700]

@@decentgarage Got the indexing thanks for the advice! Was able to drive it home from work, but it was super sluggish and wouldn't accelerate unless I did my best to get rpm by manual shift it (a518) would you say I need to turn the fuel screw in more?

[@blakedelay149]

Hey I was wondering, I already have installed 50hp injectors and have a 3200 govener spring that is ready to be installed and I want to get a new fuel pin and crank the fuel up, but my truck has the manuel getrag 360 and I don't want to tear it up, right now there's nothing wrong with it and I want to keep it that way even if it means leaving the power where its at, ive only had this truck for about 6 months and am new to diesle in general and don't really now what I'm doing, what would you suggestion be? Would the trans be okay with the upgrades or would I need to do something to the trans before all that?

[@decentgarage]

Great question Blake. The answer is that your trans can handle any modifications you do, it is simply a matter of how you drive it. I could have 700 hp / 350 torque and as long as I drive it conservatively my stock transmission will stand a chance. Once you start hot rodding it or towing heavy you will run in to issues. I would say a 3200 gov spring and 50 hp injectors are fairly safe for your transmission though.

I installed a 4K in my first gen (ve pump) and it won’t start back up

[@decentgarage]

You either have to trim the 4k spring exactly right or reindex the throttle. I am guess that is your issue

[@luisdaboy9578]

@@decentgarage apparently you have to be a professional to change a gov spring, so all mechanics say I mest up my pump

[@decentgarage]

@@luisdaboy9578 not true at all. You have to be careful but you don't have to be a mechanic.

I installed both Hungry Diesel Fuel pin and 3200 governor spring. After adjusting fuel screw, I was able to get it to started, but.....in test drive at higher RPMs, when I depress the clutch to shift (have 5spd Getrag), the engine rev'd up. Had to slow engine revs via braking. When I do not rev the engine, there was no problem. Any thoughts on what to do to keep the engine from reving up when I depress the clutch?

[@decentgarage]

It sounds like you are close to runaway and may have the fuel screw turned in too much. This is called governor hang and is the step right before reaching runaway.

[@jamesmayfield7135]

@@decentgarage I have adjusted the fuel screw such that, at the current screw setting, it runs well (except for problem described). When I back off the fuel screw half a turn, it runs very roughly, but still experiences the same problem of high revs. When I back it off another half turn, it will not start. Basically, I am unable to get the truck to run and not have the high rev issue. Considering just removing the 3200 governor spring and replacing it with the original. Ackkkk

[@decentgarage]

@@jamesmayfield7135 Sounds like your throttle indexing is off by one mark. Make sure it is indexed correctly.

[@jamesmayfield7135]

@@decentgarage Wellllll I replaced the 3200 governor spring with the stock spring. Still has the Hungry Diesel fuel pin. Worked just fine. You may be correct on throttle indexing, but am just too dang frustrated. Now....tomorrow I will be installing the Diamond Eye Stainless Steel 4" Turbo-Back Exhaust - just watched you video. Thank you very much for responding.

[@decentgarage]

@@jamesmayfield7135 Just take a braeak from it, do the exhaust and come back to it. My videos make it seem like i get everything right the first time but that is definitely not the case. I actually prefer when installs don't go perfect because that's when I learn how to diagnose the issue and I have to year things apart multiple times so it gives me repetitions.

I haven't had any issues with my automatic, knock on wood.

[@thomasdrake8630]

@@decentgarage my main problem is towing steep grades under load. The jump in the gear ratios is too much. I've even swapped in 4:10s with posi, which was a massive improvement, but the weak link remains the 48re. It's a 2004.5, & now looking to move on to 6 speed NV5600 to match my year model.
