  1. NGK BP6ES-11 plugs are no longer available? I guess I’ve fallen behind the times . Nine months ago I replace my 75 280 NGK BP6ES plugs and no problems finding them. I just tried to purchase new plugs at my local parts store and all they have is the resistor version. My research indicates that NGK is no longer making this plug? Has anyone used these in the 240/280 without problems?
  2. Do you need the white lens or the entire light unit? ron

  5. Hey Steve did you find the pictures of your 200sx clock? Would like to see which one you have. Ron
  6. Steve, Sure I'd like to see what you have . I might even have one the 200sx clocks. Ron
  7. Just thought I would add a couple of comments. The prices that are being mentioned are from 2012. This was for a 240 clock converted to a quartz unit. Costs on everything has really gone up. Look at what gas prices are today. If your talking about converting to a quartz mechanism you first have to find a quartz clock and then refurbish/repair the mechanism. The cost for a quartz mechanism, Kanto Seiki, use to be $20, in 2012 , but today everyone thinks their clock is worth over $100 because it says quartz. Most quartz clocks don't work correctly or need major repair. This gets into trying to find parts, which are not available. In my shop I have to mold gears for the mechanisms I use because parts are not available . Finally you have to modify any quartz mechanism you use to fit the clock housing, especially the 240. This all takes time and patience. The current Kanto Seiki quartz mechanism I use has 17 unique parts I have to fabricated/modify so that it will work in the 240 clock housing. I'm currently working on using a different quartz mechanism that is available, cost effective, and will work in the 240 clock housing. However, it 's not a plug and play as and will still require many modification to the mechanism. My goal is to significantly reduce the price of a 240/280 clock converted to a quartz unit. The right up on the Equss quartz clock was good , but left out a lot of detail. I have done this conversion years ago and it's not easy and you have to fabricate or modify nearly every part. It can be done, but plan on spending several weeks getting everything to fit and work. Just my 2c......Ron
  8. Well, I'll join in with my spam story. On this site I had a spammer send me a picture of a clock he was trying to sell. The numb nuts sent me one of my own clock pictures I used several months ago in an add. Oh, and another tell is "my paypal has problems, but I can use my son's" or "please send payment with friends and family and send me a copy of the transaction". right.
  9. Where did you get the picture of the clock ? You might look at the site where you pilfered it from as there is a copyright infringement.

  12. I noticed this tread and have a couple of comments. There are three clocks talked about here which are all different and have unique problems. The 74 260z was delivered with two clocks. Very early 74 the clock was the same as the 240zand the later clock was the 280 version. So we have the 240, 280 and what appears to be a VDO clock that are all different. As far as the 240z goes if you put 21volts on any of the clocks you will cook the parts. This clock is very sensitive to dirt, grease and oil. If you look at the enclosed you will see what oil does to the clock gears. Oil collects dirt like a magnet and turns into grease. This is what stops the 240 clocks. Disassembly and cleaning is the only way to put the clock back in service for many years. Also, inspection of the bearing points in necessary or you will be disassembling the clock within a short time. Again the enclosed shows a worn bearing and this part needs to be re-bushed. All the oil in the world won't help this condition. The 280z mechanism has very few bearing points and does not need any oil. The caps on the circuit board are the main problem and the spring is the second as well as the pink gear (missing teeth) on the enclosed. The other problem is the coils on the circuit board. Either of the two can be open,shorted, or incorrect resistance. As far as cleaning DO NOT use the cleaning solution as mentioned. This is an old clock makes formula and is VERY VERY caustic / dangerous. This is as dangerous to your lungs as using epoxy paint without a respirator. The cost to make such a formula is about $60--80 depending on where you can get the items. Also, the ammonia(20%) can only be purchased at a chemical supply house and runs about $35 / quart! Also, this formula will destroy and degrade the nylon and plastic of your clocks. DO NOT use it. Isopropyl alcohol is the best solvent and yes it takes a little elbow grease, but it works. I am not a clock maker, but I have repaired , cleaned and refurbished many grandfather clocks as well as hundreds of 240- 280 clocks. Oiling is something you should due for a grandfather clock as it has weights that drive the mechanisms that weight several pounds. With this kind of force on pivot points and bearings need to be oiled. Our Datsun clocks do not have this kind of force on the pivots. The 280z mechanical clock has several bearing that support pivots that are plastic and they do not need to be oiled. The correct way to oil something, if you must, is one drop of oil on the bearing/pivot and wipe off all visible oil. Clock oils today are synthetic and have a much higher load and degree of temperature resistant than organic based oils of the past. Hope this helps. Ron
  13. If ZKar doesn't have one I have a couple of other sources that might. If you do find one I would have it rebuilt. There's a good place in nothern CA which charges like $190 , but they do a really good job. My damper looked go after I removed ,but the rubber was cracked. On the car it was wobbling about 1/4 in.
  14. You might e-mail zKars and see if he has one. I tried to find one for my 280 and couldn't so I had mine rebuilt. Not cheap , but better than no air. Ron
