Hi Chris,
I shall do that and take detailed photos to further check for any damage to the teeth. If it is the teeth, that means i would have to get another gear?

Hi Sam,
Sure, but you can see the damage clearly once you remove the grease. Just look closely

Hi Chris,
It would be like last time, i did not remove the head but manually moved the laser head assembly along to clean off the old grease. The teeth if damaged would that be on the lower one, if so i would have to screw the top off? anyway will investigate

HI Sam,
Yes, just take out the gears and use a toothbrush to remove the grease. Where the teeth mesh you might find they are bent or partly torn out. There isn't any play in these gears, so if they hit the end of the travel and have enough power driving them, it'll simply chew the gears up. You might have lost the teeth on the rack on the head, so take it all apart and look at everything carefully, and under a bright light.
I'm hoping they are okay, but better you know than just guessing. A Sony mechanism for another, similar head might have compatible gears and motors. Of course, since you would have an entirely new transport, you would just install it. Look for the KSS-210 complete mechanism if you need the gears.

Hi Chris,
Hopefully the KSS-210 will have the gears i need. Now i see why I was having issues at the end of disc, and the occasional skip.
Teeth on the white cog are munched. The laser head i am not sure how to take it off, but its teeth look fine
I guess I will have to be in contact with seller. I love the player, so a replacement gear or mechanism is needed
I wonder is this place is safe?

An externally hosted image should be here but it was not working when we last tested it.
Hi Sam,
That's exactly what I expected to see. That's what happened when you tested the feed motor and the sled hit the end. That's why we want to motor to be driven just enough to turn and not any more power than that.
I haven't a clue where it's safe to buy this stuff anymore. My suppliers closed down years ago. My one source really hurt when he shut down. Everything was legitimate that he sold.

Hi Chris,
I think it was like that maybe before and this the sled hitting the end did more damage. i only use 3.5v - 4.5v, too much, needed something like 2v or something
WES has some, this catalog is old 2004

Hi Chris,
I am waiting for the email, but from memory the KSS-150A laser was 45$. This is the place my friend who a tech, now makes dacs, said he had 3 lasers dead from them, but at least they use paypal! I need that mech ! for parts.

Hi Sam,
Yes, but they have look-alike Chinese motors that are terrible. I'm pretty certain that the $13 mechanisms are with those. Also, there are KSS-240A and KSS-210A without the brass bearings for the slide rail. The angles of the pictures never seem to show that area.

Hi Chris
so you think they are using the cheaper mechs and selling them for more.
just realised i could search the codes on the retail website
KSM150B mech is $45.05 and KSS150A laser is $45.05
The original motors are made in taiwan I think on my KSS-150A mech.

Hi Chris,
I went to play it again on the first track, was fine at first then all static etc? Laser failing? or is it due to the stuffed cog wheel thing? It was only track 1

KSS-210a based CD player not spinning
I believe the laser unit has died. CD will load, does not spin. The laser does go through calibration attempting to focus, then CD is ejected. I video'd using iphone, forward camera. Only in dark conditions can I see a faint light. Only scope and DVM. I don't believe I have anything sophisticated enough to follow latched signals. If I was able to acquire a KSS-210 with brass inserts is switching a plug and play? Would the unit require any special tools or testing equipment?
thanks.

Hi MaccAu,
Disassemble the laser head from the mechanism. There is a short to go on the head before you disconnect it.
Clean everything right to bare surface, no oil at all. Clean the head and the gears too. Look at the slide opposite the rail for the head. Look for warping and / or cracks. If you find some, the head might be fine and the mech is scrap.
Use some fine, single weight oil, pure. Nothing added. Place one drop on the rail and coat it evenly. Slide the rail into the cleaned head and ensure it travels back and forth easily. Too much oil will stick things up. Use some very light white grease on the slide, then reassemble the head assy. Check that it moves freely back and forth with zero sticking. If it is clear, then put the gears back in, Pretension the anti-backlash rack on the head.
The proper replacement for the head is KSS-210A. The KSS-150A heads had problems and some melted down in the coil area at the top of the head.
The disc motor is probably in need of replacement. New head needed, you do need a new spindle motor. The spindle motor is most often the problem.
Treat the plastic lens like a camera lens. Make certain it is spotlessly clean.
-Chris
Very good advice.
The slide rail does often develop cracks which causes the laser head to stick and jump. I've had good success by smoothing the cracks with very fine abrasive paper.
Also, it is very worthwhile to remove the black plastic lens shroud and clean the underside of the objective lens and top of the collimating lens. On a dirty mech I've picked up more than 0.2V pk-pk on the eye pattern just by doing this.

In the days when KSS replacements were of good quality they were pretty much 'plug and play' although a good tech could always tweak the usual settings to get the very optimum RF quality.
KSS210 with brass inserts I believe are long gone and the generic replacements are just plastic. They are cheap enough to take a gamble on.
Thank you for your responses. The spindle motor? Would the issue be windings or brushes? ie , can I measure whether the motor has gone bad? The player was working with no issue, then, next evening's listen would not load a C.d. It was not a gradual symptom. thanks again. So much knowledge and help in here. amazong.
Spindle motor issues are usually brush related. A quick fix (it does work but is considered a bit of a bodge) is to run the motor up from a 9 volt battery for a few seconds in each direction.
I suppose one measurement would be to at the ripple/noise across the motor but this is not normally done and in any case you would need a reference value to work to to judge if the motor was defective (unless obviously massively noisy). This is something we used to do with early VHS video recorder drum motors and it was an accepted and approved method.
You MUST isolate the spindle motor first if you try zapping it with a battery.
