The spike and momentary return to normal suggests a poor electrical connection somewhere. Things to check are: REC/PB swtich (clean with contact...
Have the impression someone posted about this problem before, so I suggest searching on Google (works better than forum search). Given the...
Looking at the board, those traces can't be for the motor as they're too thin and also motor drive IC (IC601) is on the bottom board. It can be...
I think the capstan bearings should also be oiled, since it's a metal to metal contact, especially if the mechanism has been submerged in IPA (so...
Added this and the RX626 to the list, thanks for sharing ! HX head isn't always mentioned, likely because this head existed both in permalloy and...
CX-5 and CX-7 (both with and without radio) are identical as far as the mechanism goes. CX-R7 has the capstan motor on the opposite side, but by...
This SMD electrolytic can't be mounted on a side and vertically it would interfere with the mechanism. I would use something like this instead:...
It's not uncommon for leakeage to corrode traces on these models. Seen breaks at the contact between trace and capacitor pad, usually not visible...
Yes, sparks at the commutator are always produced because the windings of the rotor act as an inductor: it charges when powered, then stores...
Haven't worked on this model before, so not sure what is the reason capacitors were replaced. If caps leakead on the PCB, it's very likely there...
Do you have a W&F measurement screenshot from WFGUI ? The pressure motor spindle puts on the rubber disc is given by the spring tension. If that...
The whirring noise is likely coming from a worn capstan ring, it's quite common on D6/D6Cs to be loud in operation for this reason. It's why I...
The ticking is likely back EMF from the motor (from sparks at the commutator-brush contact). Fact a larger belt eliminates the problem means the...
30Hz difference can be considered in spec. Even the manual gives +/-1.5% REV speed differnece, which means 45Hz. 30Hz is just 1%. Yes, W&F can...
This is very disappointing in regard to the new gears. I suggest contacting the seller and let him know about this problem, as it seems very...
Replacing only the rubber tire I do NOT recommend, because almost always such roller assemblies become eccentric. Generally speaking, don't...
You are sure it's slipping on the hexagon and not on the shaft ? It's possible the hole of new gear is slightly larger (to avoid cracking), case...
