1965 450 crawler dozer

[RMAC]

I took the front engine cover off yesterday and discovered the source of my leaks, one was from a transmission coolant line, and the other was from the neck of the oil dipstick, that just need tightening, and the hose I was able to cut at the break and still had enough length to re-attach, I'm going to replace it with a new hose before I put it back together, in the process of trying to find the source of these leaks I had to powerwash the area around the hoses and discovered quite a bit of the wiring is cracked, does anyone know if there is some type of replacement wiring harnesses, where I can just replace everything from the ignition switch to the starter to the alternator? Also I have very little braking at the foot brake and wanted to know if I adjusted them thru the brake band adjusting screw on the side of the machine? I replaced the muffler, but the gasket that came with it was flat and appears in the manual to be flaired so I'm not sure if Nortrax gave me the right one, if anyone is familiar with the correct gasket please let me know. The machine seeems to be running great now and seems to have quite a bit of power, it still is going to require some additional parts, but it's ready to work, I can't believe how welll it is designed as you can take just about everything apart with basic tools, no metric bolts on this dozer, it seems to be 100% USA.
