So I just got a good deal on an old Beseler 23c II (not XL), with a 35mm neg carrier and an M39 lensboard. It's my first enlarger. I haven't gotten a bulb, lens or easel for it yet, and after that I still have to learn to develop paper competently. Overall, I'm excited to set up a darkroom where I can make prints.

I knew the Beseler was going to have to have a little bit of work done when I bought it: the (for want of the technical term) carriage that rides up and down on the frame, carrying the head, appears to have been installed crooked. If you look at the photo, you'll see that the plastic washers peeking out on either side of this carriage have been installed so that the big washers are kitty-corner to each other (circled in yellow), and the same with the small washers (circled in red). It seems that this is causing the carriage to be crooked and, consequently, the film plane of the head is not parallel to the baseboard. I will note that everything else functions on the enlarger, but obviously it will be basically worthless until all the planes involved are brought into parallel.

Note that the big frame is not bent in any way; I checked it out and the pillars are parallel to each other, and, in the side-to-side axis, perpendicular to the baseboard. The front standard has been locked in a slightly tilted position, perhaps to compensate for the slant induced by the improper assembly--obviously, once the other part has been fixed, zeroing in the front standard to be parallel to the film plane and the baseboard will be no problem with a spirit level and a crescent wrench. I've looked it over thoroughly, and I am convinced there's nothing wrong with this enlarger that can't be fixed with hand tools-- just an amateurish job of reassembling it after taking it apart to oil the pinion gears or something.

So, ladies and gentlemen of the forum, I come to you for advice on the process of disassembly and reassembly. Would it suffice to swap the washers around so that the big ones are on one side and the small ones on the other? Or do I have to make new soft plastic washers (I can.) Is there something else going wrong? Anything to watch out for in the disassembly/reassembly process? Thanks!

EDIT: My bad, I looked at it just a second ago and all four washers are identical: they have a flange on them, and the ones circled in red are sitting on the flange, whereas the ones circled in yellow aren't sitting on anything at all.
EDIT AGAIN: It's the rack and pinion. One side is off by one tooth.

Yea, I have seen this a couple of times with Beselers- someone reassembled one tooth off. Should be an easy fix, just be careful if there are any counterbalance springs (which the 23C may not have).

So I took off the gear housing on the side opposite the crank. It's one tooth high on this side. The gear appears to be held on with a pin. Is this a drift pin that I can drift out in order to slip the gear off and reposition it? The pin has a hollow "C" shaped profile.

I believe so. Although do you think someone disturbed it? If it was set up that way from the factory I would look first at where the previous owner made their mistake in reassembly.

I see no damage to the enlarger anywhere, save a tiny amount of rust and some paint flaking off the bellows. The pin and gear both look fine.

I have repositioned/replaced plastic gears with drift pins, piece of cake. Just be sure you have the right size drift- then it is very easy.

Thanks for the advice. I will get help from my friend who has a set of drifts.

I did this once upon a time and don't remember the assembly but believe I had someone give a hand
keeping the head lined up putting the pin back

Not sure if this is helpful, but the 23C II manual can be downloaded online and contains a section on realigning the carriage within the frame:

Thanks! I had already downloaded it. The insane thing is that, while I was moving it this morning, I jarred it very slightly and about three teeth snapped off each gear! I was in a bit of a panic because I just spent money on the enlarger, but I see they sell the exact replacement part, complete with drift pins, over at Blimie and Hermann for 30 dollars. A setback to be sure, but life is full of setbacks.

Bummer. Beseler is still in business and sells parts for the 23C. I wonder if they might have the replacement part for less.

Thanks! I was about to check and see if they had a catalogue. It's always nice to see a venerable company like that still in operation. It gives me hope for continued support for darkroom printing in the foreseeable future.
