Who gas welded the intake pipe and did you test it for leaks?

The mechanic.

I don’t know if he tested for leaks.

oh my tha was a lot of work. You have done an exceptional job. I will be tearing int mine this week and will be referring to some of your posts to try and keep me on the correct path. Thanks

The radiator shop says the core is rotten, and they’re working up what a core replacement will cost. It was cooling and not leaking, and I had already spent a lot on this swap. I wanted to space out the radiator expense if possible. The mechanic made the radiator leak trying to “fix” it, doh. Now I’ll have to come up with the money to do it now. If I wait, I’ll be waiting until April-May when the snow is gone.

The radiator will be ready on Friday, and I’m ready to pay. It’s not something I want to cut corners on. I have a friend trying to talk me into adapting an aluminum radiator the same size, and he’s mentioning obvious pickup prices. He knows nothing about construction equipment. He thinks I’m being overcharged, while both the mechanic and my service manager friend thought I’d be paying more. I think what I’m doing is the right thing to do to protect the engine, and stay as durable as before.

Yes, rebuild it (radiator in this case) as close to it was new as possible. Mfr knew what they were doing. Cheap aluminum radiators are for the car that just needs to run another year before it goes to the junk yard. Of course, your loader is not likely to run 12-18 hours a day 6 days a week in a gravel pit any more, either.

A high performance/custom built aluminum rad. would cost a lot more than a recored original. Don't know how durable an aluminum rad. would be in a loader. Could get a lot dirt, dust and other crap blowing through it. My rad was recored and zinc dipped to strengthen the fins. Original Cat rad. was steel but no longer available.

 

[mountainguyed67]

I have the radiator back, it looks good. Maybe I’ll go put it on in a few days, we have storms forecast for Sunday and Monday. I wouldn’t get much done in that.

 

[Birken Vogt]

Is it forecast to rain as bad down south as it is up here? Are there any burn scars that might affect you? It will be interesting these next couple days on the Eldorado and on the Plumas with these 2 big fires.

No, you’re supposed to get 7-9 inches, we’re supposed to get 1-1/4” to 1-3/4”. That’s here in Fresno. My mountain place is supposed to get between 3” and 5-1/2”.

We go through burn ares from 21 to 14 miles before our place.

Yeah, could have mudslides.

 

[Rustyfender]

Sounds nasty out there, is this common weather you experience often?

 

[Birken Vogt]

Not exactly common, average once a winter but there could be some winters where it rains gently and very little and other winters where it does this several times. Interspersed with sunny weather or light rains. Summertime from June-September it never rains at all, just hot and dry. The woods become impassible in winter, no logging or construction activity at all, too steep and muddy to accomplish anything.

 

[mountainguyed67]

Birken explained the weather good.

Yes. My mountain place is on an unplowed road, the Forest Service doesn’t travel it during winter. People in 4WDs clear the fallen trees just enough to get through, then in the spring the F.S. Improves it. The mechanic who helped me also drove logging truck in our area. He said the same as Birken above, the roads are too steep to log during winter. I’ll see the loggers hauling their equipment out the day before or day of first snow forecast.

 

[Rustyfender]

I guess that is mountain living, certainly different where I live, we just get snow, but nothing like we did 30 years ago

 

[mountainguyed67]

The mechanic that helped with the engine is digging out a stump.

 

[mountainguyed67]

I never posted a picture of how the air inlet turned out. You can also see where the fuel filters were moved to, they were where the top of the inlet now is.

 

[Rustyfender]

You have done a nice installation there.

 

[mountainguyed67]

One of the tilt cylinders started leaking, so I brought it down to re seal.

 

[mountainguyed67]

You have done a nice installation there.

Thanks.

 

[Rustyfender]

When you did the work on the 471, did you have to remove the crankshaft pully? I have to change mine from 1 engine to the other and I have no clue how to remove them, hopefully the ranks are the same other than tha with a little luck it should be ready for installation if weather holds
