-I Just finished cleaning one of my Corsair II PTO's recently and I have a few thoughts regarding the process. Ten Tec sells a kit for approximately $20.00 if you want a complete set of new mechanical parts for the rebuild. However, most of the time simply cleaning the existing parts works fine and may give the same longevity results as replacing the parts, IMHO. I believe where the brass PTO shaft is held in place by three steel ball bearings in the front of the PTO is where most of the brass filings that impair performance are generated. It is my belief that after the shaft has worn some, it does not contribute as much debris from the filings and may last as long as a new kit, again, ​IMOH.  I have cleaned a number of PTO's over the last 5 years and they are all still going strong. I do this for a few friends and myself. I have 6 Corsair II's and they are all EXTREMLY EXCELLENT RIGs ! ! +I Just finished cleaning one of my Corsair II PTO's recently and I have a few thoughts regarding the process.

 The following are some suggestions with a little humor that may save you some grief as you rebuilt your unit. It is not difficult but can be a little tricky if you don't make a few notes. I do recommend purchasing the PTO Kit from Ten Tec as it is contains an excellent internal drawing of the PTO, a complete set of mechanical parts and some high viscosity grease, as well as reassembly instructions. Only $20.00 or so while supplies last; who knows if the parts will be available in 5 or 10 years. The following are some suggestions with a little humor that may save you some grief as you rebuilt your unit.

   -Put a sign on the front door letting the Jehovah Whiteness people know that you are already saved but both of your neighbors are HELL-Bound and need their help desperately. Your Neighbors may start cutting their grass at 5:30 AM on Saturday mornings to get back at you but your PTO will be working perfectly and you will be up anyway snagging a new DX contact.   -Put a sign on the front door letting the Jehovah Whiteness people know that you are already saved but both of your neighbors are HELL-Bound and need their help desperately.

   -Put the Cat, Dog, lizard and especially any annoying, loud birds outside. After thePTO has been reinstalled and the Corsair II is working great, leave the Bird outside; the Corsair II will surely work better as a result. I had an African Gray Parrot that liked to mimic CW during contest. This QRM was settled once the bird found a new and loving home. Hope the new owner liked sloppy, left footed CW.    -Put the Cat, Dog, lizard and especially any annoying, loud birds outside.

-  -One of those magnets on a wand is handy if you happen to drop one of the steel ball bearings, springs or locking pin on the carpet. Sorry but the magnet will not help with the brass parts no matter how much you disagree with the laws of Physics. You will also need a #1 and 2 Phillips screwdriver,​ needle nose pliers, lots of low lent, shop towels. I like the blue ones from the Auto Stores. Other items needed are Q-tips, a small 1/4 inch open-ended wrench, 71% Isopropyl Alcohol. Don't clean the pistol or other plastic parts with the Alcohol just the metal items. I cleaned the Pistol and plastic parts with a Q-tip and a water moistened towel. You will need a few drops of Super Glue such as Radio Shack Future Glue, part number 64-2331. Ten Tec uses high viscosity axel grease such as Exxon'​s,​ Unirex N-2 and enough to do several PTO's comes with the Ten Tec kit. I prefer using 1 Synthetic Universal Grease from Mobil, bar code 71924 96102. This product is available from automotive stores for less than $5.00 for 12.5 ounces. This grease is optimized to minimize wear while working under very high temperatures and pressure. I can say that I have not observed any wear between parts using this product for several years and absolutely no CW chirp, at least chirp generated by the PTO.+  -One of those magnets on a wand is handy if you happen to drop one of the steel ball bearings, springs or locking pin on the carpet.

   -There is a little locking pin that has to be removed and reinstalled in the PTO shaft. I use a worn, and very small diameter Allen wrench and the butt of ascrewdriver to tap the pin out. Just gentle tapping is all that is required and once the pin starts moving, it can be pulled out with needle nose pliers. To reinstall the pin GENTLY grip it with a small pair of wire cutters and once started, press the pin in place with a miniature pair of channel lock pliers.This is the worse part of the rebuild and isn't that bad.   -There is a little locking pin that has to be removed and reinstalled in the PTO shaft.

-**From the Ten-Tec Reflector June 20, 2000** 
  
-Phil Wood Bicycle grease sold at bike stores makes the claim that it is good until the inclusion of dirt.... ​  Over the years I have used this grease for PTO applications (and many other applications),​ and have never seen it to separate or harden with time like just about all the others. ​ Try it, you may like it !!

-I called a local fancy bike shop some time back looking for Phil Wood grease and was told they had it, but only in tubs.  They filled a 35mm film canister for me free.  That ought be enough of the stuff to re-grease 50 or more PTO's. 
- 
-It has been in 5 PTO's for only a year but sure did make them work smooth!

-Phil Wood grease is indeed great stuff. In addition to being a great lubricant it is also water proof making it great for fishing gear or other exposed applications. The non-hardening nature of the formulation would make it ideal for PTOs. It is also inexpensive! Most bike shops can get it or it is available nationally from:

-This is a well known mail order discount bike store. The main disadvantage is it is green and tends to stain.

 This is a high quality board that has a look and feel similar to the boards that are used in the Corsair II. I mounted mine vertically along the case edge, just to the right of the .25 filter position, using an existing hole in the chassis. ​ This is a high quality board that has a look and feel similar to the boards that are used in the Corsair II.
