[C36IA] M35B heat exch'r tip

[Gary Davidson]

Great minds think alike! Last year I rebuilt the heat exchanger and had
the same trouble re-mounting it. In my case, I squeezed the brackets
closed as Fred suggested with vise grips, but held them tight with small
plastic zip ties instead of wire, started the threads, then clipped the
zip ties.

 

I also found that the mounting holes would accept slightly longer bolts,
which combined with the zip tie trick, really made the job easier!

While changing the zinc in my M35B's heat exchanger during my spring
servicing, it was clear that the old zinc had broken off and was inside
the raw water water chamber.  So I removed the heat exchanger to get it
out.  If you ever have to do this, you'll find that without some
creativity, it's almost impossible to get the heat exchanger remounted.
the problem is that the two mounting hoops that attach the tank to the
aft end of the block are very strong springs, and the mounting bolts are
not long enough to go through the holes on the ends of the hoops unless
the sprung hoops are compressed.  Two hands aren't enough to do this,
and there isn't room for two people back there.  Here's how I solved the
problem:

 

Before putting the heat exchanger in place, use vice grips to compress
the hoops as much as possible while still allowing them freedom to slide
around on the tank.  While compressed with the vice grips, put a wire
tie around the bolt hole flanges on the ends of each hoop, so you can
remove the vice grips and the hoops stay compressed.  Then put the heat
exchanger in place, position the hoops properly and engage the first few
threads of each bolt.  Then you can snip off the wire ties and finish
tightening the bolts.  Voila!!

 

Tuck this away in your memory in case you ever have to do this.
