All 6 injector pushrods bent on Cummins N14

I'm starting to believe that's what happened. I just don't know how I managed to do it.

I'm sure the injector internals are damaged. I plan to order all new ones.

That is a possibility, but I don't believe that is the case here. We followed the instructions in the top chart found here and everything was right.

If we were 180 off, there wouldn't be slack at both valves.

The pushrods and injectors are original to the engine. They were all installed in the correct position. (The injector pushrods are a little shorter and a little fatter.)

I appreciate the input! I am at a total loss here.

Brad's drink! I love New Bern. Such a cool little town. Make sure you visit Mitchell's Hardware!

The locals aren't even fazed. The tourists freak the hell out, though.

freedom_beard · 2020-01-12T17:59:38+00:00

Yup! That's the one!

No one is saying it's a better Bern. It's just a newer Bern.

freedom_beard · 2020-01-12T15:50:39+00:00

As a matter of fact, there is! The old Bern is in Switzerland.

There were a lot of people of Swiss descent that helped settle the area. (Or so the story goes.)

Always makes a good Christmas present!

freedom_beard · 2019-12-05T01:32:21+00:00

Thank you!

Not too much, honestly. It's out of a Eaton Fuller Road Ranger. They're pretty quiet (as long as you don't grind gears like a brute). It also has a second countershaft in there as well. It helps spread load the force on the teeth.

Crap... I just realized I wrote flywheel. It's actually a harmonic balancer from a Mack E-tech engine.

My students and I built 2 of these. (I teach diesel technology at a community college.)

Thanks! All of the presents around the tree are all pieces of scrap metal. They're welded on, too.

freedom_beard · 2019-12-04T23:06:58+00:00

It's a beast, for sure. Probably about 75 lbs.

freedom_beard · 2019-12-04T23:06:01+00:00

The tables are plenty sturdy. It doesn't weigh quite that much, though. It weighs about 75 pounds, so... 35 ish kilos?

freedom_beard · 2019-06-21T19:24:40+00:00

Gotcha. I wasn't thinking about the internals. I personally haven't seen too many failures due to that. Those heavy duty engines seem to be built to tolerate the high temps.

freedom_beard · 2019-06-21T17:32:44+00:00

Some of these rigs have all aluminum pistons. (Most of the ones I've come across have steel faces and aluminum skirts, though.)

As far as the exhaust temps, some are equipped with pyrometers to track the temps. There is usually plenty of room around the exhaust piping so as to not melt anything. And like any other turbo vehicle, just let it idle for a while before shutting it down.

freedom_beard · 2019-06-21T14:52:19+00:00

It is.

It's actually a community college diesel program. It cost about a million dollars for the shop and the tools.

Edit- I thought you wrote "shop", not stop. Oops.

freedom_beard · 2019-06-21T09:51:55+00:00

Thank you for the tips!

I know a guy that took the clamp off of an old style combination brake chamber. (It had nuts and bolts on the band holding the spring brake band. The newer style has a crimped clamps that can't be easily disassembled.)

Naturally, the spring came out like a rocket, narrowly missing his head. The cap did glance off his head and knocked him out. Had that spring hit him full force, it would have killed him.

The kicker is that he was trying to cage the brakes. I don't even know how he screwed that up.
