Im pickin up what you put down.. That sucks. The last p.o.s. job i did was pulling a mack tranny out of a granite dump truck,outside on a small hill, using plywood on the dirt to roll the jack.  That job sucked..  

ive done the same thing but it was level ground,,,,lotsa rocks,,,plywood and a pallet jack and of coarse alone lol.bob

Yup  plywood on a side hill done that too! Improvise! 🤔if you don’t do it it ain’t getting done!

I have changed some clutches out in the yard with a sheet of plywood it adds to the job when the jack doesn't roll worth a darn

I'm going to drop the radiator off and look to have it recored.  It doesn't leak, now, but with the added power/heat I want it to be good for awhile longer.

 

I reckon it's cheap insurance on a good motor 

I got the R model done, it was crazy expensive, I think all Australian Macks of that era came with the biggest radiator you could get

 

I can't remember the exact price, but it was over $5000 Australian 

Back then, with the exchange rate it was about $3600 US

You probably felt the earth tremor when my jaw hit the ground

But compared to the cost of a motor it is cheap

I am not holding my breath until I get a price.  It won't surprise me if it is crazy.  But this is a very small radiator compared to an R model.

The original has worked flawless for 25 yrs.  Even on the biggest, longest grade I run it just gets to 200* and just holds it.  It is a 9* grade in Pennsylvania.

Late 2000 teens, I had a recore on my 9670, and it cost $2150.00so not at all surprised by your figure. It wasn't the biggest radiator IHC put in that truck either. I'm sure the biggest would be close to what you paid.

add $400 to that price for the used radiator I bought to start the project.

Yeah I would guess around that also but I understand they are still available good luck Larry
