Kodak Carousel S-AV1030 Projector Advance/Reverse Problem

[franco330]

Hello all, first post. I have been sorting our historic family slides and bought a Carousel. It was in great working order until a plastic slide fell apart and jammed the gate. I had forgotten from years gone by how to remove the tray in any non-zero position and extracted the slide in bits!

Sorting resumed. After about 60 slides the transport failed - neither advancing nor reversing.

I found a video on the forum which incidentally showed how the transport should work - and mine doesn’t. The image blow shows the peg which doesn't move.

I have had the case off and admired the German engineering but can’t see how the mechanism should work.

Can anyone offer a fix or a steer to find out more please. Is the a service manual available?

Thanks in advance for any advice or pointers you can offer. I can’t face sorting 3000 slides by holding them up to a light!

With the case off, have you picked out all the remaining slide pieces?

Carousel projector problems often come down to lubrication having dried or become thick and gunky with age. Two places to look (with the case off and the unit lying upside down) are the tongue that moves the magazine and the solenoid between the main motor (not the fan motor) and the two cam wheels. The tongue should be able to move freely in both directions when operating and when changing between forward and reverse. The solenoid operates a toothed clutch but the assembly needs to be able to slide freely along the steel shaft so as to engage and release with a definite 'clunk' when an advance or reverse is required. You can check it by hand (with the power unplugged). If either of these mechanisms isn't moving freely, lighter fluid is very effective at dissolving claggy grease, followed by sparse re-lubrication - don't overdo it. The cam wheels benefit from a careful clean and grease such as Castrol LM (car wheel bearing) but the solenoid should not have anything that heavy. Note that the tongues operated by the cam wheels do so only when the machine is in its normal orientation and will appear to be doing nothing when it's upside down.

There's a site that may be useful at:

and a parts site at:

I used to work at a university where the Carousels got a real thrashing but very rarely did anything wear out if they were maintained properly. Resist any temptation to fiddle with the cam-operated electrical switches - they rarely give trouble.

Good luck!

Great thought. I have a look when I go exploring tomorrow. The Frank

Thanks Steve. Really helpful advice.I shall spend a happy time tomorrow.

Really useful l because there seems to be little published material out there.

Btw I wouldn't be in this situation if I hadn't mistreated the machine to free the slide. Ugh!

Cheers

Well thanks guys, I followed Steve's excellent instructions and all is now well. Brilliant and thank you.

I wanted to attach a couple of videos so that this thread could be a good reference for the future but the upload limit precludes this so I have attached a could of images.

The shaft which ultimately drives the two cam wheels when activated by the solenoid (left) should be lubricated allowing the wheels to rotate freely on the shaft.

and...the shaft upon which the pinions slide also should br lubricated. It is exposed when the clutch (nylon colour) is engaged. I cleaned the cam wheels and lubricated them.

There was not much dry grease but lubricating the shafts has made everything run more smoothly. It also fixed my problem with the magazine/reverse - how the advance/reverse motion works is still a mystery.

Perhaps I'll post the vids on YouTube

So, again thanks of the advice Steve, I have now finished sorting my slides.

All the best
Frank

You're welcome, Frank. Glad to be of help!
