Re: 450 C charging/starting issues

Stan,

Thanks for the information. Can i simply run the one wire from the one and only terminal on the alternator to the battery terminal on the starter solenoid? Same as going to the battery itself?

Re: 450 C charging/starting issues

You are correct. it is an amp meter on the dash that doesn't work. I do have the Tech manual but, as you called out, it is with the old motorola and wiring. I got confused by it and relating it to my one wire system. I have not dug into where the wire from the alternator is going yet. it goes into a...

Re: Advice on 450c complete rebuild

So the mechanic removed the block and pulled the pistons. The sleeves were all ate up and pitted on one of the pistons. He then inspected the inside of the block and it had wear and pitting on the inside of the block on one of the cylinder walls. Yes,the coolant was leaking from sleeves/internally. ...

Re: 450 c Fuel problem

So does the vent tube come out after the screen is removed or is it apart of the screen? also, if you take the screen out could it be possible not to get it back in correctly? Also, i'm not able to d...

Re: 450 C Final Drive

Re: 450 C Final Drive

So I am checking the fill plug on the side of the final drive (back of the dozer) where the gear is. not on top of the track but behind the dozer. that's the final drive fill level correct? I could be wrong on this one.

I did a cursory check the other day and found that the fluid was above the fill plug again. Where would this e...
