Worm Gear Replacement Tutorial -16mm B&H 1500 Series Projector 

This is an amazing video and was instrumental in my successful replacement of a broken worm gear. If someone reading this is contemplating the fix, I will say it’s quite involved and you need a healthy dose of patience and a well stocked tool box to pull it off. That said, this is the video to follow. No question. Thank you!!

Could not have replaced my worm gear on my projector without your video. Followed your instructions to the letter and had no problems. My Bell & Howell runs like new! Thanks!

Trabalhei em uma oficina de reparos em equipamentos cinematográficos durante 12 anos. Os B&H eram os que mais davam entrada para reparos, principalmente essa engrenagem helicoidal partida. Foi um grande erro da B&H usar nylon na confecção dessa peça imprescindível para o bom funcionamento do projetor. Deixou muitos operadores prejudicados durante exibições. A solução que encontramos era levar a peça danificada para um torneiro mecânico de precisão que a replicava em bronze, resolvendo definitivamente o problema.🇧🇷

Thank you for sharing this insightful video. I just purchased a 1580 on ebay supposedly with a burned out motor when in reality it has a split worm gear, wish me luck!

Great Video! Thank you On some B&h projectors there is a 015533 Lower Sprocket Gear 1575/1580/2580 On which i replace also with the worm a lot on times its cracked where the film bunches up at the sound drum this gear should be replaced even if its not bad . its as old as the old worm gear I have these in stock RC's Classic Collections

I have several of these... Thankfully the worm gears are good.. Good on ya to tackle this.. Who ever came up with all this wonderful old technology.. Not something for me to tackle.. Only a select few would be interested in watching this.. Thanks for posting.

Thanks so much for making this video! Could never have figured it out otherwise. Only had to take it apart twice!

9:40 "An' this gear jus' pops right out..." ...When you said that, I wondered if it would actually pop off, and it didn't dissapoint ;-). Thanks for posting this, and for being brave enough not to stop the vid to look for that e-clip that sproinged earlier. I just bought a 1550 cast-off from a video equipment rental establishment because i have a sound film of my great-grandfather from 1935 for which i had rented a 16mm 30 years ago to videotape, which afterwards i copied to DVD thinking the DVD would last forever. Well the DVD no longer works, and i can't find the original VHS, and no one rents 16 mm any more. The establishment turned the machine on and it seems to work, and didnt seem too noisy, but i didn't want to bring my film with me so i didn't actually check it with film, and still have not yet, for various reasons. Your vid gives me confidence that i can fix the worm gear if it doesn't work properly. I am surprised that the sound systems on these do not seem to be problematic, considering capacitors do not last forever. I'll keep my fingers crossed.

By the way, thank you for making such a great video. I could have never taken apart and rebuilt this projector without it. Also, as a note, you don't have to have the Bristol tools that are sold as a kit. I got the small vortex screwdriver set from Harbor Freight and it worked fine. The most common screwdriver part was the 9mm vortex, six-side.

Super video which will help many people.

I'm going to replace the worm gear on my 535. Can you tell me how many different Bristol flute screw sets I need and the sizes. Thank you, in advance, for your response.

4 months to do the first one... I got ya.. I remember trying to set the timing on a 48 Victor...

How would you approach getting the timing right on a 1574 that does not have loop restorers?

Amazing amount of know how to fix that. What would you charge someone to fix a projector ? Belt and Worm gear ? thank you.

Thank you sir for this video!! I found a dealer in Belgium for the Xcelite 99PS60 set of Bristol screwdrivers. In an answer of one of the reactions you talk about n66. Could you please have a look in the webshop of The equipment depot and let me know if the 99PS60 serie contains all of the needed blades for the 1698 B&H projector? May I also ask you if changing the worm gear of this 1698 projector is much different of the one you show us (1545)? Thank you and greetings from Belgium.

Any suggestions on a good agent or technique to use to remove all the old grease

Pretty good walk through. I wish though, you had worn a helmet cam or moved the chassis over some, as I could not see any of your adjustments of the loop restorer. Also, there isn't any RU-vid videos that I've seen, that cover replacing the worm gear on a 500 series with still frame feature. That's what I have and Urbanski doesn't sell a worm gear for any model with the still feature. There were a lot of parts on the worm gear shaft that ended up being junked, because the still feature can no longer be used. Your video and the British guy's video, helped me a lot, so cheers 🍻

How much time do you recon that someone who hasn't done this before but is a handyman would spend on this?

Do you have a source for the gears? They seem to be sold out on ebay.. Also, about how much time should a newbie budget to do this?

What sizes of Bristol tool do you need. I heard you mention a 66n

Does anyone know where I can get a motor capacitor for my b&h Model 1585 Mine blew up

hi. my film inside the projector is moving fast and jumb,after i installed warm gear.maybe i didn't put the frame right, is not plear the picture,i try to move the focus lens but nothing..can you give me one advice what to do.the projector is grabing the film, it has good sound but no picture the imagine is foggy not clear and vertical lines.

Wow what a pain in the a#$. I'm getting ready to do my 2585 as it's split in half. I hope it's a lil easier. Can't find a worm gear for under $94 shipped either.

I replaced the worm in my 1574, but I obviously didn't get it sync'd. Playing film is a third at the top, 2/3rds below. I'll go in one more time, but how do I know it's correct? Can I send you just that part to sync?

After another 20-25 hours working on this, I've put it together but can't get the gear at 9:35 to "catch" and turn the other gears. I have taken this off, replaced the U clip from another projector and also changed out the gear. Do you have any tips on what it can take to make this all work. Other than this, it appears everything else is good.

Thank you for this tutirourial I tryed www.filmtech.com for parts but google could not fiind it. Can you help?I need worm gear and drive belt for my 2558 BH Thank You.

$94.00 shipped for worm gear, $65.00 for the bristol wrenches, geeze they really know how to screw a guy just to watch my old movies.

And at 37:44 you have a bit of a problem getting the wormscrew rod out and then at 37:45 you have the ball bearing in your hand. What happened in the black zone? I can't get this out very easily either and I don't want to damage it.

Hi, the worm gear is stuck to the rod, in the video it slides right off. I completely removed the set screws on it and the loop restorer cam. I've managed to hammer it to the end of the rod, but it is stuck as if it is bolted in. Any clues?

Is this good to use for a 2585 ? Also, what do you go by in the 16mm group? Couldn't find anyone under " highrollersmusic1. " Thanks for all you've done here ! Anxious to get started on my 2585 !

I would really love to know what tool you used to take out the bottom two screws that are holding the wormscrew chassis. This is at about 20:49, where you show the needlenose pliers lifting out the screw. I have purchased 4 different rachets and two pliers and still can't find a way to get to these bolts. If I could take off the motor in the front, that would be easier, but I can't get the back left screw out of the motor frame. Any suggestions?

After watching your video probably a hundred times, I give up. I posted on your Facebook page about how I could ship my projector to you for final repairs. Please let me know. Thank you.

First try on my rental store cast-off 1530 purchase, and the film autoloads to the pickup reel ok, but machine slows and stops once i get the film on the take-up reel and doesn't want to move forward any more. But turn knob to reverse and film backs out no problem. Machine runs Fwd fine with no film loaded, but stalls once film reaches the takeup reel. I only had a few moments to play with it before wifey rushed me onto other things. Could the introduction of the thin film really put that much drag on it? It had no problem running the film backwards. The reverse button on top of the machine was frozen when i got it, now there's no resistance when i press it. Could the reverse button be causing my issue?

do you know that at the end of each shuttle arm is a very small single roller bearing that the shuttle teeth sit on.

Where do I buy all the tools I'll need, to fix my 1585 c bell and howell, 16mm filmosound projector, is there a website I go to, I'm replacing the worm gear

I'm just a bit unclear at the end here, when your run the test strip through the chassis. Exactly how can you tell that everything is accurately in alignment? Obviously, I don't want to put the entire thing together and find out there's something that needs to be tweaked. Can you outline specifically how to do this final once-over and what you're looking for in the test strip?

This tutorial is for the 2592AX model? It is from the 2500 series, and I have the worm gear broken.

How different is this procedure for installing the worm gear specifically for B&H projectors with the "still function"?

I have a Bell & Howell TQ3 1695 it needs a new worm gear I'm looking for anyone who could do this replacement for me please holla me
