12.5 Kohlar question(s)

[Chuck Wheeler]

Bob,

I did replace the insulation at the same
time I did the engine housing. I think I still have some in the box at the
storage unit. I will check for the name.

Chuck,

Did youreplace the soundproofing
insulation over the generator? If so, which did you decide to use? Mine
needs to be replaced soon!

I know what you mean about the generator
being cramed in a small spot. I replaced my 6.5 KW Onan with a 10KW diesel and
had to do some "re-arranging"!

Thanks Ralph, I kind of guessed that you would be the one to
reply!

I would appreciate the picture! Usually I can figure things
out, but there is no logical place for the spring I can see. I have the
generator out and am trying to get every thing done by next Saturday.
That’s when I have to return the pallet jack that I used to remove it and that
it is currently sitting on. I would gladly pay you for it plus the
shipping costs. I am not sure why they put a 12.5kw in a FC31. It
is on a smaller tray than normal and is very cramped to try and work on when
installed. That’s why I decided to take it out and do everything right.

One question I forgot. My high temperature cutoff sensor did
not pass the test. I discovered that there are two resistance sensors
installed like would be used for a temperature gauge. The cutoff should
be a switch. I am guessing it would be set for 200-210 degrees. Do
you have any information about the cutoff sensor?

My guess is that we will probably be out of town during the X-Mas
Rally. During the holiday season Kathy’s Real Estate work slows down and
we usually are travelling to visit family for the Holidays.

Hi Chuck:



Tomorrow I will take a photo of the spring location and send it.

2. Are you going to be at the X-Mas Rally? if so I will bring you a boot

for it.

3. The micro switch was an add on for some reason and not needed.



Safe travels,
