I’m interested right up until you said made of the same material. The material they used is why they failed.

Disconnecting the positive on the battery does nothing. If that theory is correct then you have to consider that everything is DC which means a positive and negative is required for all the electronics and if you don’t remove all the negative ground points to all the electronics there is still a...

Yes the ECM has a battery in it, I know because when it the battery in my ECM died I had to pay Caterpillar a lot of money for a new ECM and for them to reprogram it. When it happens it it causes a crank and no start situation.

I’ve welded on my LMTV many times along with welded on many other vehicles and equipment never disconnecting the batteries, sometimes even when the tractor is running. Never had a problem with electronics. Just be careful what’s on the other side of where you’re welding because the heat will...

Absolutely the best in all those categories. I think our trucks were built with McMaster parts. always the best quality and great description of the product unlike Amazon.

McMaster Carr sells them in every size and configuration. Search lanyards.

They truly don’t need the air foil. Before I decided to put my mini split A/C unit in the middle behind the cab just above the roof line. I was concerned going 60 mph that the wind blowing into it would cause problems manly because the directions say not to allow more than a 10 mph wind to blow...

I bought my 2003 M1078A1 5 years and have driven it over 5,000 miles. 2,000 miles at top speed of 58MPH and RPMs screaming at you with the original gears and got 3.5-4 MPG. I changed the ring and pinions out added a rear locker and had CAT reprogram it to 330 HP. Driven it with this...

I had a similar problem, I’ve owned the truck for over 5 years driven it almost 10,000 miles the one time a short 7 mile trip after parking found gear oil leaking out of the vent tube pretty badly checked all the normal stuff cleaned it all up and it hasn’t happen again. Never could come up with...

I gutted everything and filled every hole and started with a clean slate. Before After Still working on it.

How many gallons did that add to the tank? I decided to weld a whole new tank actually 2 tanks. I built the big one taller and much longer making it 185 gallons and the small one is 40 gallons.

Has anyone purchased that laptop and data port from kt3406e? I’m seriously considering it. If it is everything he says it is it would be a great tool for someone like me that does all of my own repairs.

My ECM failed me as well years ago. At that time I couldn’t find anyone that I trusted to do the repair so I bit the bullet and purchased a new one from CAT and then it was on them to program it at they even upped my horse power to 330. Any ways it might just be they didn’t fully repair your...

Is that a Napa store?

For the large oring for the two wheel halves I ended up canceling the McMaster order because of the lead time and because when I received the new ones from Hutchinson it appears they are using a different compound the the original orings which took on the shape of the wheel. My guess is the...

Go on McMaster Carr site and look at o-rings. They do a great job a describing the different materials and application. Then pick based on your conditions such as needs to be gas resistant or heat resistant and so on.

Post your installation of them.

Set up bearings are also very useful. In my local town I’m the guy everyone wants to have do there ring and pinion set up for their Jeeps. Been doing them for over 20 years. But those are new gears with new bearings and shim kits. I would be nervous about doing these gears not having spare shims...

Thanks for the explanation that happened to my cab lift once and freaked me out. It finally started working but I never understood why and what fixed it.

My 2003 A1 did that when the ECM / Engine control module died. I had to get a mobile cat service tech to connect to it and diagnosed it.
