Nice work Rudy and thanks for posting it here with photos. It sure helps somebody like me who knows zilch about diesel motors. Visuals help immensely.

I was under the bus yesterday. I noticed that one of the bolts on the donut gasket flange for the exhaust was missing.

I just so happened to have the perfect bolt, washer, and nut.

I put it on then I started the motor to check for exhaust leak. No leak. Another successful task completion.

While I was under there, I discovered something cool (actually warm). It is a heating unit. It is on the side of the oil pan.

In this photo, notice the electrical plug.

The wire is attached to a box on the side of the oil pan.

I haven't tried it out yet. I hope it works. I wish I had known about it this winter.

This is known as the injector pump. The pump I replaced is known as a lifter pump. I'm glad I did not have to replace the injector pump. These pics were sent to me by Chuckles. They are from a craigslist ad.

Here you can see the injector pump on the left. It gets fed by the fuel pump that I replaced. Then the injector pump meters fuel to each cylinder. I presume it is driven by a cam or a gear in the motor.

Mark Obtinario confirmed that this unit is indeed the reservoir for the power steering. The reason that there is only one hose attached to it is because it is not a pressurized system. Mark suggested that I not fill the reservoir all the way up because it will overflow.

Old fuel pump is now removed.

This is where the new fuel pump will go in. You can see the cam that drives the pump.

These are the last two photos of the fuel pump project. The new fuel pump is installed. No more leaks.

I would like to again thank all of you who have helped me with this project.

I hope the photos of this project can provide some insight as to what is entailed.

I'm very happy for you Rudy! Even happier that it was on top of the engine rather than having to wriggle around underneath during the winter.

/cheers

This is from an email I sent to Ezrablu today.

Ezrablu and Lois are two new members who have contributed many posts that have won the hearts of the "bus family".

On a daily basis I get somewhat excited about my impending change of existence. I was under the bus yesterday. I checked out a bunch of stuff. Overall, it looks great. I have some reservations about the lower radiator hose.

Today I looked at my stuff in storage in one of the barns here. It was scary how much there is in there. I had to leave the barn in a state of wondering, " WHAT am I gonna do with this stuff?"

I did NOT want to bring any of these things in the bus. I do realize, though, there are some things that I need to keep. The problem with that, is that I now need to scrutinize what is already in the bus, and get rid of some things in order to make room for the stuff that is in the barn.

Now, if I had a 60 foot bus, I could take everything. Of course, I would be terrified to drive something that big. Even now, when I sit in the driver's seat of my bus, with the motor running, and pretending I am driving, I am intimidated by it's wide front end. Also, sitting in front of the steering wheels is kind of freaky.

My head is spinning.

I will make lists of things to do. Lists are fun when you can cross off tasks that are completed.

I think I must play accordion today.

As Lois always writes, "pat your doggies for me"

Lists are great

Here are two questions.

Why do the brake lights go on and stay on when I switch the parking lever to park when the motor is running? I'd sure like to disconnect this function. It sounds like a tricky task.

On the bottom of the placard, it says Emergency Stop. Does that mean if my brake pedal malfunctions, I can use this lever to stop the bus?

Post by **Sharkey** » Sat Mar 26, 2011 3:04 pm

Q1: Your brake lights come on because they are activated through the air pressure system. Putting the brakes in "Park" is the same as mashing down the brake pedal hard, so the brake light switch supplies power to the lights. Defeating this is not a trivial task, you'd have to rewire the bus a bunch.

Q2: Yes, throwing that lever down while the bus is rolling would lock up the brakes, assuming that there is no malfunction in the brake actuators/linings. That's why there is that lockout lever on the left hand side that needs to be moved before you can throw the lever down. You woudn't want to lock up the brakes at speed. Also, this works only on the rear wheels, the front brakes don't have a "park" feature ~and~ they won't lock up if the brake system loses pressure.
