Re: RE: [drakelist] C-Line PTO Friction Question
[EMAIL PROTECTED] made an utterance to the drakelist gang -- PS Since the Drake tuned the PTO coil, and other brands tuned a capacitor, there will be some inherent differences in the amount of friction, unless some more expensive measures are taken with the PTO (e.g. Collins).** Need a new ride?

Gary Poland [EMAIL PROTECTED] made an utterance to the drakelist gang -- I have had to several times in the past, disassemble the entire dial mechanism and use emery paper to open up the nylon busing that the front dial mounts to. That is the only way to fix swelled dial parts. 73, Gary -- Submissions:[EMAIL PROTECTED] Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net --

Re: [drakelist] C-Line PTO Friction Question
Curt Nixon [EMAIL PROTECTED] made an utterance to the drakelist gang -- Hi Wade: Not sure about the C line but my original R4A/T4x is still smooth as silk. It won't free spin, but I can place my finger into one of the flutes in the knob circumference and just move my finger in a circle and easily spin the knob from one end of the band to the other. There is nothing in the mechanical mechanism that would create any friction to speak of. Old grease or other lube could get gunky I guess and should be flushed out and replaced with teflon grease or similar.

Re: [drakelist] C-Line PTO Friction Question
Garey Barrell [EMAIL PROTECTED] made an utterance to the drakelist gang -- Wade - I have owned / worked on a LOT of 4 Series units since about 1964, and I've never come across one that would 'spin' the way the old Hammarlund and Hallicrafters flywheel driven dials would. They should however be easily tuned by resting your finger on the side of the knob (or in the button on the C Line) and moving your finger in a circle. The PTO is driven directly by the lead screw and follower within the gearbox at the front of the PTO. All the gears are there solely to drive the dial disc(s). An excellent article on the foibles of this arrangement is at: http://www.wb4hfn.com/DRAKE/DrakeArticles/PTO/Drake_PTO.htm The article is based on the C Line, but is applicable to all the 4 units that use the nylon gears. The big secret is that nylon gears are designed to run _DRY_ , i.e., no lubrication at all, especially petroleum based lubricants. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line TR-4/C Service Supplement CDs www.k4oah.com H D MAC LEOD wrote: H D MAC LEOD [EMAIL PROTECTED] made an utterance to the drakelist gang -- Hi Drakelist.

Re: [drakelist] C-Line PTO Friction Question
Dave White [EMAIL PROTECTED] made an utterance to the drakelist gang -- I've rebuilt a couple of the C Line VFOs using the article referenced by Garey - excellent information. Something that I found affects the freeness of the tuning mechanism is the tension on the spring that holds the idler gears against primary shaft. Too much tension causes the gears to force their engagement and consequently causes more friction and increases overall drag on the mechanism. You can experiment with lower tension springs (or stretching the original), but proceed at your own risk!

RE: [drakelist] C-Line PTO Friction Question
wmacleod [EMAIL PROTECTED] made an utterance to the drakelist gang -- Thank-you both Garey and Evan. From your descriptions I expect the units I have need a small amount of lubrication on the worm gear and main bearings. I am familiar with the article mentioned below and will be careful not to contaminate the plastic gears.
