Ok, no flat cam lobe here! That’s good. I haven’t seen or heard of any cam issues yet on these Lister Petter engines. One of the other members here has had issues with the oil pump relief valve sticking. It’s an interesting scenario. Because the oil pressure has no place to go, it pumps up the...

That’s good news right there! Your persistence and determination is going to pay off. Some of these units need more than others to get them up and running. It appears that you will have a running unit before too long. Just wondering, did you ever swap holes with the IP’s to see if the problem...

That small amount shouldn’t be a problem.

You guessed it, the cube type. They have a high failure rate huh?

I’ve had a couple of different 802/803 units where the auxiliary fuel pump didn’t work. Have you heard yours running? As LITD said above, simply select the auxiliary fuel setting on your master switch and if everything’s working correctly, it will draw from the auxiliary source only to keep the...

It’s pretty involved to get those IP’s set up correctly isn’t it?

I wish these engines had compression releases to take the strain off of the starter and the batteries while cranking them over to check things like this. But they don't. Hopefully you have a means of keeping the batteries charged up while you're doing this stuff. Also, don't use the dead crank...

The only variable that I can think of is cam lobe height. I don't know why else the shim thickness would be so far off. But for now, we're just trying to figure out why you're not getting any fuel out of #2. So, maybe write down what shim thickness that you originally had under each IP. Then...

Just some more thoughts to hopefully ease your mind. I know that I've mixed up the IP shims on a unit or two, and they still ran. They might not have run as efficient as they should, but none the less they still ran. By swapping those IP's around and cranking the engine over, you should be able...

I neglected to ask. Did this unit have the exhaust stack flap in place when you got it?

Interesting. I wonder how many different IP's were used in these engines? To comment on one of your other posts, it's very common to see a little rust on these IP's. These units may sit unused for long periods of time. Condensation will prevail, especially in high humidity places. Like others...

Don't lose faith! These units are pretty bullet proof. And yes, many times we see units that have been "touched" by the wrong people. There's a ton of help in this forum. There's also a lot of parts available here. Have you kept track of what shims came out of what hole? If you're curious about...

The thickness of the shims under the IP's is for timing purposes only. The amount of shims under the IP's should not make any difference for whether or not the IP will make pressure. The rule of thumb is to reinstall the same shims that came out. The procedure for determining what the shim...

It appears that there are (3) different threads from sidis8 now on the same topic. Would it be possible to combine them all in one thread? It may get better results. When reading the other threads, it appears that cylinder #2 was not producing any fuel out of that pump. Much like swapping spark...

I was just looking at the Lister Petter master parts manual. It seems that they've used (4) different fuel pump manufacturers. They show Lucas Dizel as the "current" one. Part #751-41322. Past manufacturers are Omap, Bryce and Stanadyne. It's possible that the drawing and the specs shown above...

Absolutely 😁

It’s called “the path of least resistance.” Much like the path that electricity follows, we often follow that same path. You’re not alone my friend!

Just like you, these well nuts have kicked my tail. I often think about a quote that I once heard. "Pain is a great motivator for change." Well, it's painful for me every time that I deal with these well nuts. I even posted a thread a while back looking for some good direction in this area. It...

That’s right! I forgot that part🧐
