Radiaror / Engine cooling, best fan set up

[wbute]

An old Chamberlain we had with a John Deere engine it let go from it. Took about 9000 hours though. One sleeve was hammered in one spot. Looked like a sandblaster had been at it. Got another old Chamberlain that blows head gaskets because the sleeves have sunk down on the o-rings. I have replaced the head gasket twice now mainly because it's cheaper than rebuilding and machining the block to fix it.
Cooling systems are more of a "system" than is realised as you said. It should be fairly straight forward to get a V8 Holden right. I never saw too many issues with the Cat 793 trucks I drove at Cadia. They were 2700hp V16 operating in temps from below zero to over 40. Running out of the pit under full load for 30 minutes to get to the top! That was a real eye opener for me.

Great chart WB. I bet those 793's were running 3516 engines, they are the Cat success story, big cubic displacement, diesel fuel under high pressure and plenty of forced induction. Yummy!!!! I bet they sounded awesome at 2100rpm with full load and a steep incline. Having said that, we eventually got rid of all our 3516's as they were just too expensive to maintain on a cost per kW basis. That's when we went with the Cummins equivalent. Anyway, good chatting about high horsepower diesel engines for a bit.

Yep everything is just huge on them. You could get heaps of info up on the dash. One thing was litres of fuel per hour. Coming out of the pit loaded with 250 tonnes they burnt 380 litres per hour! First time I pulled into the fuel bay and filled one up I was glad I wasn't paying. 3000 litres, for one shift of 12 hours. They ran 20 big trucks.
You can put the recovery bottle anywhere within reason. They work with pressure equalisation, not a syphon. I think they were screwed onto the radiator support on HX.
