+spongaweb I was running an 824 on a job right off the 91 fwy and the 71 in Corona back in the early 80's. A couple of 37's had just unhooked and were dropping down into the fill when the rear tire on one of them exploded right next to me. It was a sidewall blow out and so a chunk of tire about the size of a large dinner plate shot out about 100 feet and smashed a same size whole right into my fuel tank. Whenever I grade checked after that I always felt a little uncomfortable when the scrapers passed by me. Being cut in half would be a fast way to go though. Thank God I made it to retirement in 2008 ! lol

+Gary Smedley glad you made it mate - i ran 657's in UK for a couple of decades-they are the machines of my choice

John Kirkwood depends on material but yeh they gain around 40+ tons

My favourite KZfaq master chef/Baker. And I find him on the most random video. Cheers John.

@@jimmyjohnson7769 load limit is 104000 I ran many of them

Cat have been there own worst enemy sometimes and scrapers are a case in point, they just made them to good back in the day.

Gavin84w I suppose so, but parts make more money for a manufacturer than the initial sale of the machine, and look at the parts demand and duration for these B's If the Denver warehouse didn't have my C parts Hayward did, always. now it comes from Morton which tells me when Mortons out thats it no more of that part, Some one commented once, "Its hard to justify a $30,000 dollar transmission for a machine thats only worth 30K" My reply was what do you mean that machine is worth a million dollars to me, I think this video proves me right, look at the number of repowered 57B's apparently dirt guys in CA think so too .By the way who engineered this repower? was it the people who make parts for them? You are right "they just made them to good back in the day" No electronics and good quality parts.

you tell them Jpaydirt love the channel

Old is an "A" model .....now I think there past G .....but I like B and Es ......hydrolic over hydrolic. ....not the new electric over hydraulic

copperheadmarine me to my friend

Awesome that's better then i expected. Keep up the good videos.

I dont know much about these types of machines, but i have seen similar ones in other videos, so i think it is just a standard machine from Cat.

It’s a 623 cab with a water wagon on them. Can’t remember the company that builds the tanks but they can be ordered like that from cat

By the hour ,$50@ hour

They are B's Rentrac retofitted the radiators to have repowered engines in california

Perhaps better parts availability and cost - certainly not better engines.

In the UK if they re-engine - (rarely), it is always with CAT never Cummins. Mind you CAT have the UK pretty well covered in dealerships. A lot of our 'Heavy Haulage' 75 Tons+ tractor units are CAT powered irrespective of make of the vehicle, - (they seem to share the market with Rolls Royce in 'Big Power' units - even generators).

Maybe in California, they repower Cats, but here on the East Coast I've never seen a cat repowered with anything but a Cat.

I've yet to find a CAT in the UK that has done so much work it needs re-powering. They just strip the engine down and replace the worn bits.

2nd that. Kitty all the way.
