[DeTomaso] Transmission viewing hole cover

Generally not much air will move through an opening unless the air has
somewhere to go. In this case the bellhousing is pretty much sealed
otherwise so I foresee little air movement.

Is it possible that the spinning clutch assembly act as an
"impeller" so to speak and draws in cooler air to aid in cooling? Some of
the older units have 2 ports and maybe this acts as an intake and exhaust.
Just some food for thought. Anyway, I'm keeping my cover on just to help
keep dirt, grit, and other nasties from getting in while you drive every
day.

Dear Tomas,
My very amateur evaluation and opinion of the cooling
capacity of
the bellhousing port is the same as yours: It *cannot* provide
very much
cooling! Oh, well.
Warmest regards, Chuck Engles

I personally don't think that the open hole provides much cooling
but if it
does I don't think some small holes will be enough to preserve
that cooling
capacity.

Just drill some small holes in the cover?

Dear Chris,
If you do find such a screen, then please let
me know.
I would be interested.
Warmest regards, Chuck Engles
PS: the lovely color coordinated plastic covers have proven to be
satisfactory for boy racer high performance!

Wow, so as it always seems to be with Panteras, there are two
answers to the
question!
Maybe I'll see if any vendors carry a screen for it since that
would answer
both questions at once...
Thanks for the info,
Chris

Dear Chuck,
You wrote:
1) how important is it to have the hole covered,
and
"Yes to prevent some tool or debris from falling in.... and no(t)
to allow
heat to escape."
Just before or during the Phoenix Rally, I was told that
the
bellhousing port was for ventilation to allow heat to escape.
I guffawed at this bit of ZF trivia. At the rally, I
checked with
our POCA President and ZF expert, Les Gray. I was shocked that
Les
confirmed that the port was indeed for ventilation. I believe he
said that
serious racing European Panteras have screens that cover the port
to..."prevent some tool or debris from falling in...." and to also
allow
heat to escape.
I have had my two Panteras adorned with the tastefully
color
coordinated port covers for a total of 100,000 miles. There have
been no
known problems. The recent cross country escapade to Phoenix and
back, over
2,334 miles, by the same two Panteras at healthy speeds for long
distances,
likewise, produced no sign of a problem.
So, that is all that I know about ZF bellhousing port
covers.
Experience seems to show that no harm seems to be done in normal
Pantera
driving with the port covered, despite what the original ZF
engineers
thought.
Warmest regards, Chuck Engles
