Bell & Howell Cube Projector Main Drive Gear

Timely delivery and exactly as stated

Recently, I hauled out an old Bell and Howell cube projector to sort, downsize, reminisce, and possibly copy some slides. I was ecstatic that the bulb still worked. Unfortunately, the projector didnt. After studying a rather simple looking you tube tutorial, I learned that the most likely culprit was the plastic main drive gear. I ordered this piece from Amazon, it arrived relatively quickly, and I dismantled my projector. The sprockets were indeed chewed up on the original gear. The wiring in my projector was a bit more complicated than on you tube, but still, with a little patience, maneuvering, and the brute strength of a 70 year old woman, I managed to pull out the old gear and replace it with the new one. It fits perfectly. I only gave this piece 4 stars because its nothing more than a small piece of plastic, and the cost is high. On the other hand, at what price do you measure the joy of recapturing your youth while laughing at everyones wild antics in your old slides?

***my old, replaced gear is in the photo, not the new one!!**** Found my grandmothers slide projector and box of slides, and I was very excited. Went through about 20 slides and the carousel started sounding terrible and wouldnt turn well. I looked it up on YouTube, and sure enough there was an exact repair video with reference to this part on amazon. Took me about an hour to replace this main gear with the video instructions, but it was a perfect fit and has me back to enjoying the slides from the 50s! Thank you for offering this part!! (The gear I got was white, not black, but it really doesnt matter!)

Bought this to resurrect an old slide projector and it fit perfectly. No complaints.

When my Bell and Howell slide projector began to fail I determined that the main drive gear was the culprit. There is quite a lot of disassembly required to get at and remove the worn gear so keep track of what youre removing and where it goes. My internet search for the replacement part at Amazon was fast and easy and the new part worked perfectly. One more thing: you have to adjust the gear mesh between this gear and the gear teeth on the slide carrier so there is no binding, but it is easily done. Im pleased to learn there are still parts available for a projector of this vintage!

Has held up through 2000 slides I just duplicated to digital (WHEW!!!!!). On line instructions linked to dont really explain how to specifically replace this gear, so I will: 1) disassemble ONLY ENOUGH TO POP OFF THE BACK SIDE OF THE PROJECTOR. You only need to loosen the top enough to fled up a tad so you can pop out the back panel (which is held in by small tabs that hook on the frame, they just need a little clearance to pop the back off at the top edge & lift out at the bottom edge). 2) take off the lamp replacement access door on the bottom to get better access (from bottom and side, at this point) 3) You can see the (broken) gear at this point from beneath, and the (good?) large white gear that drives it. Use hex socket to remove screw through hub of large white drive gear, slide it off its shaft. You can now slide the broken black gear off its shaft, replace with the new one, put the white gear back on its shaft (wiggle to get its teeth to engage the new black gear teeth) and re-assemble everything in reverse order.

After 20+ years in storage, I brought out my mid-70s B&H 981Q slide cube projector to see if it still worked. It did - sort of - but wouldnt reliably advance slides and when it did the shutter wouldnt reliably open either. Spent several hours tinkering with it before I spotted the mostly toothless top of the drive gear. Went to YouTube (where I should have started), found a video or two about the problem which lead me to order this gear that got it purring along fine again. Looks like this part will be a lot more durable as well. My 981Q projector is configured a bit differently than the YouTube how to example I found: a different non-reflector bulb and no access door on the bottom. So it took me awhile to figure out how to get it apart. 1. Start by flicking the latch next to the slide cube mount and swing up the top to expose the carousel mechanism. 2. Locate the four silver flat blade screws and remove them. 3. Then you can close the top, flip it over or on a side and start working the bottom loose. 4. When you have a bit of separation, you will be able to tilt out and remove the front and back covers. 5. At that point I used a needle nose plier to unbend some clips holding wiring to the bottom piece to free it up to pull off entirely. 6. Now you have pretty good access to the motor; removing two screws gets the motor in you hand (still attached to wiring) and the old gear will pull right off. Putting it back together is basically just the reverse with a bit of added hassle getting things to line-up and screw together.

Installed in Bell and Howell AF70 slide projector worked fine

It worked as excpected. Great material. Saved my projector to see alot of old memeories.
