I remember a video from way back showing a big power KW getting out run by a Mack up a hill in Australia . The KW driver was like WTH! I tried searching for it but never find it.

When I met Karen 20 yrs ago, they still used their rotary phone in the dining room as their main phone. I bought her a cordless phone so she could go sit on the couch and be comfortable talking on the phone instead of standing in the corner! 😆 -
Dang. Fixable but will take some Norm Abram skills. I have replaced the side door of my trailer once already and it is getting rotten again. I need to seal the wood(or use cedar) as water gets behind the aluminum sheeting. It is a day project once I get the wood cut(non std dimensional wood). If the builders would just use the right wood you wouldn't have rot issues.

It is, just fuel and timing is different. The "673" denotes a Thermodyne(multi gear trans) and the 675/676 was Maxidyne(5spd).
-
Yup, from what I have read.
-
I think the 285/300 were 676(maxidyne). The 300+ isn't the same.

Thanks Steve. What I need to know is the serial number after the Etaz673c, does that correlate with anything? 7S8762 ??
-
Ford had similar coding for clearances so they could put correct parts together without having assembler measure anything.
-
Not sure of year. Only thing I have is serial on motor. EtAZ673C 7S8762. If that means anything. I looked on Agkits and they want truck serial number. I hope we can work around that.

Shop I use can cut rings. No issue there. Using fingernail, I'm guessing +.020 deep currently. Pretty solid groove. I did get #6 piston out. Was able to wiggle past oiler. Rod bearing was 12-7 112 62GB33-P1 Crank and bearings look fine.
-
Was hesitant to pull injectors, but going to have heads cleaned up. Should I zip the two bolts out of clamp and do they pop out easily? Will there be a seal ring in hole?
-
They are at least that. The deck has 020 hand stamped at each cylinder? Protrusion is more then that? Fire ring may be that by feel?
-
They are there, #4 had some crud in the area where gasket was blown. It was going to get worse had I try to just install and run it.
-
Got the heads off. Yup, took a 5ft cheater to get them to SNAP loose. Looks like I had a head gasket on its way out on #4? Rest looks ok. Cylinders ok, no damage. Noticable wear on top of liner. Not huge ridge, but very detectable. Not a " fresh" rebuild.

I wondered what "low flow cooling" was. Terms passed around and never knew what it was about. Thanks for clarifying.
