Taka,
I've used a Motor Drive A for 15 years and not had problems. They are
pretty
durable. Make sure you have good batteries in them. They will stop
before
they pull the film out
Taka,
The winder mechanism is directly geared to turn the small roller that engages the
sprocket holes. The big roller with the 'Magic Fingers' is just there to take up the
slack after the small roller pulls the film across the pressure plate and out of the
cassette!

Thanks, I'm just trying to make sure that the drive isn't the cause of
the problem,
as I do not want the warranty period to run out, find out that I have a
bad drive and
now be stuck with a piece of junk.
I never held the rewind knob, that's not the problem. I just hate
worrying about
A follow up question- why is the drive so sensitive to a tiny amount of
dirt
in the camera? I'm afraid that the drive is marginal, if it can't
overcome a
bit of friction.
I had 2 2ndhand MDA few years back and both worked perfectly (except the
aging rubbers). I don't think they are not

The rewind crank? Are you saying that I pull hard on the U shaped
bit and the crank comes out from the top? Should I use anything to
lube the shaft before reassembly, like a Teflon dry lube?
No - hold it w/ a flatblade screwdriver, then the top screws

Taka, I will check with my repair guy on this one. Don't discount the
possibility of an oxidized electrical connection causing the motor to
torque out under load though. Give me 18 hours to find what he says.

Taka, Here is what my repair guy sez:
There is a gear set in the motordrive that starts to wear out.
The symptom is that as more film is advanced onto the take up
spool, and more torque is required to drive the film, the

I just checked Pentax USA, they no longer support the Motor
Drive Eh! either.
If the camera does what you describe without the drive, then
likely the film advance is weak, and should be adjusted while it
still works.

Does this sound like my Super A needs a CLA, or does it still

The Super Series can gett friction hang-up in the shaft/sleeve
of the rewind crank. Mine has, but its easy fix. You just take
out the rewind crank and

Thanks. If it is just gears, do you know if anyone can
fabricate the
gears if they
are not available? If they are made of plastic, I also wonder
if it
would be wise to
see if they can be fabbed in brass or stainless

Wouldn't poor contacts cause the motor drive to stop working
completely at times?
I'm not able to run a single roll through the camera w/o the

drive acting funny, but it seems as though when it works, it

Hi,
I bought a defective Drive A at Ebay. I found the problem: the connection
between the battery contacts and the wires inside is done by a metal part
which is clamped inside the housing onto the inner side of the battery
contacts. The wires are soldered to the clamping metal part. At my drive
