Durst Pro Gear Replacement

Don't get me started about Jens...

Let's just say that I have the same low (what's the word for lower than low?) opinion of him as Drew.

If someone created a pattern for the gear, maybe someone with a 3D printer could make one up?

Don't know if the printer material would be strong enough?

Found a temporary replacement.

Glennview.com out of Chicago has responded and will be ordering a new gear - he has someone who molds them for him, which is good to know.
I have ordered from Durst-Pro USA in the last couple of years and have had no problems; no response so far about the gear though.

The reason the gear got chewed up to begin with is that one of the students was lowering and raising the head by pushing the head and and down instead of using the crank.

Students, you gotta love them! L

LOL, I've seen the damage inflicted by students at ICP in New York. ICP has a lot of Saunders enlargers. The handle that lifts up the gate for putting in the negative carrier seems to get broken quite a bit.

I haven't gotten my 138 yet, but does it have one of these gears and a crank or is that only on the 184?

[Luis-F-S]

Only on the L184. The 138 does not have a hand crank unless it's an SM-183 like mine.

It's called a pinion gear. There is a #1 and a #2 pinion gear IIRC. On all of my L184's there were two kinds of gears, one made of metal (a brass alloy if some kind) and nylon. The nylon ones were the only ones I ever saw fail. The two kinds are interchangeable. I bought my replacement from Durst Pro back in 2003 and it cost me $170.

I found some NOS what I believe is 3 of the replacement gears. No part #, just in an envelope marked "Durst gear and pin" but I know we replaced these pretty regularly. Only drilled for pin on one side, and the included pin would be a very tight fit. No longer have the 184 chassis. I'll post the over in the FS section.

Hey all,

I've reverse engineered the pinion gear for the 184. I put holes on both sides so you can use a simple cotter pin. I've tested it and it works. Posting here to gauge interest in making more than a few. Likely nylon, as they'll be much cheaper. I could have them machined, but the price is much higher. The one in the image is a PLA prototype but is plenty strong to raise the head, and cheap enough that you can replace it when needed.

Anyway, i know these break often and are difficult to find so let me know if you'd like one thanks!

Sorry, I don't know why the image posted on it's side.

FWIW, for those with similar issues: the gear on the crank of my Durst M800 broke and I found a replacement at this place:
