How important is running the mechanics wire through the nuts holding the main bearing caps on? I forgot it and really don't want to pull that pan, again! This is on an early 8N.
 
Pulling the pan will be a lot easier than what could happen . My opinion , take it for what its worth, If it could happen it would happen to me .And if one comes off a whole lot more money for a rebuild than a gasket.

I've seen it on some engines that if it weren't for the mechanic wire the bolt would have come out.

I once seen a running 4 cylinder engine on a Farmall F-14 that when I tore it down the center main bearing cap was broke in half. If it weren't for the bolt locks you can only think what would have happened.

Most of the time the things we don't want to do we need to do.

It'll give you piece of mind if you go in and put the wire in.

You already have thoughts or otherwise you would not of asked all of us who read the forum.

You probably spent enough money on the tractor now you just need to protect your investment.
 
If you didn't run the engine too long I would think you could save the gasket if your careful taking things apart. my 2 cents
 
That is one of those thing that you might luck out and be ok but it could also be one that would bite you in the back sides. My self I would pull the pan and be safe instead of maybe blowing all the time and $$ you have in it because all it would take is one bolt coming loose and there goes all the $$ and maybe even the whole engine if a rod or crank brakes

I'd sure want to pull that pan! I worked on aircraft when I was in the USMC. They put that safety wire in there for a reason. An 8N might not be an F-4 Phantom, but the "crash" to your wallet could be painful if you don't fix it.

Just be sure to wind it the right direction, since you'll be looking at it up-side-down.......
 
If you replaced the nuts, and torqued the nuts down to spec, I wouldn't worry about it. However, if you do pull the pan off of it and put the wire on it. The peace of mind you experience will be more than worth the time, trouble and efforts.
 
Well you know what will happen if you don't... every time you get ready to push that start button you'll hear:

"do you feel lucky today punk" ... :)

I really like ole Clint's acting.

They call that safety wire. The Air Force has a tool for twisting those wires. We did it by hand
on V12 tank engines. Hal

T Bone, that's a good one!!

I think my favorite was "The Outlaw Josey Wales"
and "Pale Rider" was maybe my second choice

and I liked the "Dirty Harry' ones too!

Happy new and hopefully a "Prosperous" Year to everyone

Id'd wire it. I have a couple pair of safety wire pliers, they are used on a lot of machines, on things you really don't want to come off.
 
It's a darn lot easier and faster with those tools. My hands use to get sore from doing that by hand. Hal
 
harbour freight sells safety wire pliers too, and real cheap....less than $10 a pop. pretty handy for everything from race cars to fence wire!
 
Safety wire is one of the many thing that keep airplanes from falling from the sky. I would tear back into the engine and complete your work.

I've seen alot of damage and resulting expense caused by not using safety wire when it was supposed to be used. It's called safety wire for a reason... Eat the cost of the gasket, pull the pan and do it right, it's well worth the peace of mind.
 
Correct me if I'm wrong but isn't 'mechanics wire' a soft annealed black wire like baling wire and 'safety wire' is a high tensile (or stainless) bright wire? Or is it called one thing 'here' and another thing way over 'there' ? Mechanics wire has a wide variety of uses but I didn't know using it as safety wire was one of them. It'd be better than nothing though I suppose. ...Randy
 
Some tractors used cotter pins for securing the nuts. I think they would be good as safety wire. Hal
