Poked a hole in the front heat exchanger on my sled today.  How do you
go about fixing or replacing this??  It appears to be quite a job.  Any
info would be appreciated.

The front heat exchanger is not sold separately. It's only sold as part of the
front bulkhead. In some cases, I've heard of them being welded. Welding may
reduce cooling, though.

How big is the hole?

Its a small pin hole, but the stud tore up the fins pretty good in a
spot about an inch long by 1/4" wide.  Dealer is sending me to someone
they have used for repairs in the past.

That's all aluminum welding, isn't it? or just brazing?

Yes, its all aluminum.  Right now the guy that tried to weld it said
that he could not get it to hold. He said that it was popping while he
was trying to weld.  Thinks its the aluminum used is not very good.
Dealer now has a call into Cat to see if they have any ideas other than
a whole new bulkhead.

I'd like to hear the outcome. especially the cost of a bulkhead.

Sometimes (probably not this time) the welder is not familair with the
narrow heat margin with aluminum vers the (much easier) ferrous metals.
What that means the temp difference to when the metal is molten (for a
proper weld) and it blows (falls) apart, and you get the "hole" affect.
I assume he's using a
"stick" welder.  Wire feed is easier (but more expensive).

Thanks for the info.  i was also told that if its not completely dry
the moisture sucks right to the weld.  I'm not sure what type of welder
he is using, but he has done this for a few years now so I assume that
he know what hes doing.  He really seems to think that it is some bad
aluminum, I'll keep you posted.
