sl560 Rear Crankshaft Position Sensor
Hi! I've been looking for months for a CPS for a 1986 560SL, according to my EPC my PN is 0021536028.. I looked everywhere with no luck.. I tried with alternatives parts like Bosch, Intermotor, Wells, etc etc..and nothing... Any Idea if CPS 560SEC fits my car? (according to my EPC no) any suggestion??
Thank you!!
Boris

Your profile does not indicate your location, but I ordered a crankshaft position sensor from AutohausAZ about a year ago, and I believe they still stock them. About $275.

Thank you..I live outside of USA but I usually buy in USA. At this time the part No 002153628 is out of stock in all stores including Mercedes Classic, Mercedes dealers etc. I've looked in Germany, Spain, Chile, etc. Bosch does not make them anymore. There are many other companies that have an equivalent like Intermotor, beru, etc but all are out stock. Sometimes their websites show some quantities but when you buy the sensor..they tell that the system was wrong and they are out of stock. there are very similar parts for 560SEC, 560SEL but they have a different part number. I'll keep searching and in the meantime I'll buy the 560SEC CPS to try and see if it works.

I just looked on Autohauz AZ and I apologize - they no longer show it! Even the TDC sensor is out of stock. At this point, you may consider Ebay. There could be some out there.

I've been waiting for months to see if one appears on Ebay but nothing so far.. I've bought one in Amazon 1 month ago and I have to wait one more month (first time that I see a 2 months delivery time in USA) but for all SL560 owners there must be an easier option..I'll order the 560SEC and in a couple of weeks (I live in Bolivia) I'll post if it worked. If the 560SEC does not work. Then all 560SL owners could have this problem and no solution

I sold my 1987 560SL last year but in my parts bag I still have a new, unused genuine MB/Bosch crank position sensor for the M117 motor.

I have the same problem as you do do.
Did you find a solution, the one from the 560 SEC worked.

Sold a few weeks ago to a forum member in New Jersey. It really makes me wonder what the solution is - there has to be a way to fabricate a useable sensor from another MB unit.
For what it's worth, the person that did all my heavy mechanical work - now retired - said that in his 30+ year career as an MB / Ferrari tech, he never had to replace a crank sensor on an R107. Most of the time the real issue - as it was with my '87 - was the ignition control module. Naturally, these are very scarce now, too.
The way he described a bad crank sensor for these motors was that the problem would be intermittent - the car would die....then start again a couple of hours later. The crank sensor itself is made from two dissimilar metals - when hot, a bad sensor will have these two metals separate, breaking the electrical connection and bang - you're dead. The way he told me to check to see if my stalling issue was in fact a bad crank sensor....and it was not....was to carry a gallon jug of water with me. When the car died, he said open the hood and pour water back over the bell housing where the crank sensor is located. The cooler water will cause the metals to contract. If the car starts right after this dousing, then it pretty much proves it's a bad sensor. If it stays dead, look elsewhere - like the ICM.
MY 87 had a thermal issue due to a bad fan clutch. The car would get too hot and before actually over-heating, the damn motor would stall. An hour or so later - it would start. Drove me crazy. When I finally replaced the fan clutch, it was obvious that the old one was not allowing the fan to move enough air. I could really hear that fan push. It made all the difference.
Someone a lot smarter than me is going to have to figure out how to either repair or develop a replacement for the sensors that actually have gone bad - otherwise there are going to be a lot of dead R107's gathering dust or getting engine transplants.
Good luck.
