Engine/Transmission (1998.5 - 2002) How long to replace vacuum pump

[dward]

Thanks for the posts on my other thread.
I'm not liking the $1300 cost of having my pump replaced and it seemed pretty high.
I just called another shop who has done work for me and they specialize in diesel trucks. They told me it was 8 hrs labor at $125 per hour plus the pump so I'm right back to the $1300 range.
I'm liking Mr Goulds video even more.
I'm a decent wrench turner and have good tools and garage I can keep the truck in and I'm not pressed for time.
Those that have done it, how much time and skill is involved?
I've read some say to take the vacuum pump and power steering pump out together and others as Gould say to leave PS pump in the truck. What's the best way?
Also, for less than $100 would it be worth putting a new PS pump in and minus the seal kit another $200 for a new vacuum pump?
Do the new vacuum pumps come with seals installed and ready to bolt up?
For a couple hundred $$ I wouldn't have to worry if I installed the seals right and not have to worry about leaks.
Thanks

I posted here when I did mine:

My post quotes the instructions from Gould, I think, but below that I posted how I did mine without removing the power steering lines. Warranty time calls for 1.9 hours. The first time I did mine it took me a bit over 3 hours.

Be very careful about two things:

(1) The dogs on the drive adapter are VERY sharp. Be careful inserting it into the new seal.

(2) On mine, the flange of the vacuum pump that the power steering pump mounts to is not flat, in other words, the legs are not the same length. There are spacers there that make up the difference and if you're not careful, you can put the pumps back together without the spacers and it will break the vacuum pump when you torque it down.

It's not a hard job the kit comes with good instructions . If you're slow like me it might take 3 or 4 hours .

Yes I would agree taking I did mine in about 4 hours. I took both out together so can't comment on leaving power steering in truck.

I thought I described what I did in the previous post I linked above but I guess not.

I removed the driver side battery and the intake pipe between the intake horn and the cooler. Unbolt the Vacuum Pump/Power Steering pump assembly from the engine. If you turn the assembly as you lift it out it will turn right around and lay in the empty battery tray and it's very easy to separate them there without removing the P/S hoses.

Thanks for the info, I think I'll do it myself.
I wonder how an experience diesel repair shop can figure 8 hours for the job. Must include breaks and a long lunch?

I did it both ways and prefer removing the vacuum pump/power steering pump together. I found it easier working on the bench than under the hood. If you can take the units out, you shouldn't have a problem resealing the pump and reinstalling.

Not sure where the oil pressure sending unit is located on the 24 valves. They're easily damaged if they're in the way and you forget to remove it.

You've got the tools, a garage to work in, and you don't need the truck to go to work tomorrow morning, so you're laughing.

Keep posting if you run into any snags. A lot of members have done this plenty of times and can walk you through any issues, however minor.

Because they like to screw people . Didn't they tell you about the scheduled muffler bearing flush repack and replace seals that Cummins recommends at 133000 miles

Here is a picture of the sending unit location. I got the picture from Geno's garage.com Number 22 is the sending unit.

They're located between the vacuum and power steering pumps on the 12 valves. I remembered twice, but forgot once. Those little suckers are starting to creep up in price.

At least dward can catch a break and have one less thing to worry about.
