Couldn't find what you'd written at first, then saw it was buried in my quoted post.

No magnetos.
.
Did I put my post in the wrong place ? If no magnetos what does a diesel use ? A distributer of some sort ?
I thought diesels had a constant flow of electrical and it is the compression that fires the engine. Please clue me in so I wont have to ask any dumb questions any more. Thanks

Duct tape, bailing wire, gas and this.... View attachment 113130

A parts runner to go get anything else you might need. #invaluable
That's true...and though not a spare part, I haul an ebike with me everywhere. I got it first as a backup rescue/escape vehicle in case I did break down solo somewhere and couldn't get my van out. Hell of a lot easier to ride out to pavement over ten miles of desert dirt road in half an hour than it would be to hoof it for five hours.

It's also a great scout vehicle, errand runner, and pack horse. Loads right into the back of my van with ease and charges from the solar-fed deep cycles on my trailer.

Your reply to mine ended up ahead of the 'end quote' mark so didn't show in your post, but showed only if expanding my post quoted in your reply.

It is not a dumb question.

Here's more on magnetos.
Here's more on diesel vs gas ignition.

As this is a thread about spare parts, I'll leave it at that, Jim

Well I was half right anyway. A diesel fires the fuel on the compression stroke due to the volatility of the fuel. No electrical needed. Hmmm I thought we were talking about spare parts since you don't need spark plugs or points and I do ?

It depends a lot on where you are going, what you are doing, and what you are willing to pay for.

Some people rarely go anywhere that they need 4wd or low range and towing is readily available. Those people probably don't need or want to carry a lot of spares with them.

My reasoning:
1. I like to do my own repairs. Knowing what my vehicle looks like when its in good shape helps me see problems before the become major issues most of the time. I also inspect my vehicle after every major trip and give it a look over at every tire rotation when I'm going to have it on stands anyways.

2. I also like doing more challenging trails. Places where it will cost thousands of dollars to have your vehicle towed out on top of the repair bill.

My spares list:
Alternator
Front CV half shaft
Front Drive Shaft U-Joint
Rear Drive Shaft U-Joint
Both Camshaft Position Sensors
Crankshaft Position Sensor
Main Fusible Link
Inner TRE (same on both sides)
Both Outer TREs
Used Fan Belt
Various Fluids (Antifreeze, Oil, Transmission Fluid, Diff Oil)
Main Power Relay

This list is built from personal experience as well as research into the weak points of my vehicle. I'm a member of some Xterra specific forums and these parts are some of the ones that have caused problems for other members in remote locations. Some of them, such as the TREs and U-Joints are things I've personally had fail on me in the past or a friend in the group has had fail and put us in a bind because they didn't have spares.

You need to research what you drive and figure out what some of the weak spots are. Every vehicle has common issues that will leave you stranded and you need to either fix/replace them to mitigate the issue or be prepared to repair/replace them on the trail if they become an issue.

Example:
Being a little unprepared ruined a family camping trip a couple years ago. We were going across the mountain on a Saturday afternoon about two hours from home. On top of the mountain, I eased up against an obstacle and the Xterra died. It was like you'd turned off the switch. It took some cranking to get it to restart but it did. We continued on down the trail and it wasn't long before the entire dashboard lit up like a bill board. At that point, having read about common issues and their symptoms, I had a pretty good idea what the problem was. I pulled out my code reader (if you have a OBD2 vehicle and don't carry a code reader, you really need to look into one) and it confirmed my suspicions. It was one of the camshaft position sensors failing. I didn't have a spare at that time, so our only option was to abandon our trip and hope to get home before it left us stranded on the road side. Such as it is, aftermarket parts from places like AutoZone don't hold up and sometimes don't work at all. You have to have OE (Hitachi) brand and most of the time you have to order those. Since then I've carried spares for those in my spares box. If there'd been one in there that day, we could have made camp and I could have easily changed the part in about 10min after the vehicle cooled down and our trip would not have been cut short.

I personally always carry extra bearings and grease (the Dana 35 on my 94 ranger is kinda temperamental and hit and miss with bearings) and I always carry extra oil and coolant. Also I carry an extra mass airflow sensor and air filter

It's the heat generated by the high compression, often over 24-1 that starts the fire, the fuel burns. You have glow plugs that heat up for cold starts.
