ok i am going to replace the wiring harness on my 8n, the wires are just old. They are in the metal tube that runs down the block my question is when i go to remove that tube will the blots that are holding it to the block need to be torqued like a normal head bolt would, or is just to hold that tube on to the tractor.

Why remove it ?? Its not that hard to fish the wires through..

From what I've been reading and the pics I looked at, they are head bolts and need to be torqued. I'm sure someone will correct me if I'm wrong.

Headbolts are 65-70ft/lbs, studnuts are 55-60ft/lbs. Retorque after 20-30min of warmup, engine warm.

well i not only did the wires need to be replaced but i think the one bracket that goea to the tube has rotted off and i was going to braze/ tach weld it back on there
i like the exhaust pipe idea!

fishing the wires through didn't work for me.
1st i tied string to the wires and taped the wires so they wouldn't fetch up on the pug wires on the way through. i got to the 4th pug wire and i didn't dare put to hard to wreck my new wiring harness.
after my effort i just zip tied the new harness to the outside of the wiring loom.

That is also what I did. I could not get all the wires back into the tube. It works fine.

Fish mine through about 3 times over the past 12 years..No problem..
Read in one of the articles that the plug wires of today are made a little thicker than the old set of plug wires back then causing the tube to be a little tight. :dunno:
