Hi everyone,does anyone knowabout worm gears on these machines?I have a T Q II 1655 model and the worm gear has cracked,so are they as bad to repair as people say?I have looked at it and it seems a bit more complicated than my Elf models.I'm not sure about the other functions of the machine as it's not running due to the worm.Can you recommend any u.k Bell and Howell parts suppliers thanks in advance Mark

Hi Mark,
I have had many experts tell me that it's a complete tear-down of the machine (several loborious hours) to replace a worm gear. In addition, there's a gear in the lower end of the unit that you cannot see - when this other gear goes - the unit is KAPUT! Apparently, it's this other elusive gear that is not replaceable. There are many people out there that refurb projectors here in the states and sell them at very fair prices. I've been told that sometimes it's better to just keep these things for parts and invest in another unit.

About ten years ago I also had a B & H worm gear split, and a repairer quoted me £25.00 for a replacement gear, with £75.00 labour costs. Heaven knows how much they charge today.
Is it worth spending this amount of money on an old projector? Only you can answer that question.

I decided against it, and brought an Elf from a local school for £20.00. Only needed new belts. Had no trouble with it at all, and sold it last year still in good working order.

If you still want to use B & H projectors then do as Brad suggests above. Keep it for spares, and buy another machine.

To change the gear yourself you might be able to obtain one from http://www.projectorservicesni.com/
I believe that you will also require the aligning tool, but am not certain of this.

Personally I would phone up all the camera repair people who advertise in Yellow Pages.
Some of them must repair 16mm machines.

Wierd! My earlier post on this subject has now gone! Anyway, any B & H projector is repairable (despite previous thread messages) but the TQII was the worst of B & H's range (even admitted by them!). B & H projectors are also the best; kinder and more robust that Elf or any other make.

MARK: I have found a box of spares for the TQII...which spares do you need? This box is the product of stripping down an old machine.
