Subject: FW: Problems with ETX-125 Sent: Friday, October 12, 2007 07:55:54 From: Jimbo's Place (email@example.com) I'm forwarding the following email to you to see if you can help me locate a part for my ETX-125EC. I sent the original to Dr. Clay but thought I'd also see if you can help. Regards; JimMike here: You could try Telescope Warehouse (link on the Astronomy Links page).
----- To: firstname.lastname@example.org Dr. Clay, I figured out what was wrong. One of the gears (pictured with red arrow) has three broken teeth. Likely broke off when the Q-tip got jammed in the gears. Thanks to excellent instructions on Mike Weasner's site, disassembly was a breeze. Here's my problem: I called Meade to order replacement parts, and they no longer stock or manufacture replacement gears or gearboxes for the EC. Any Idea where I could find this gear ? The Meade customer support person had no idea if other 125 AT/PE or other gearboxes had the same gears as the 125EC. Regards; Jim > From: email@example.com > Hello Jim...there are no metal gears available from any source for the ETX drive > trains....the grinding is not a result of grease, but likely from a gear alignment > problem...did you check to see if the gearbox is secured firmly to both the base and to > the fork arm?
