I am restoring a 1940 B My shop manual shows a wick in the back end of the crankshaft to lubricate the pilot bearing. What kind of material is this wick made from and where can I get it. Thanks in advance for any help.

Two answers to your questions, and one comment:
1. The wicks are included in all of the complete "FelPro" gasket sets that I have purchased for the WC tractor engine.
2. I DO NOT recommeng using a wick. I like to plug the hole with a press fitted steel pin "lubricated" with "red" loctite and "stake" it in. Then use a bearing with a SEAL on ONE SIDE, install the bearing with the "seal side" facing the rear of the tractor. Lubricate (grease) the bearing with a high tenperature ball bearing grease and put some of the same grease in the cavity before installation in the tractor(before the transmission shaft goes into the pilot bearing). This gives you the same configuration as the "late WD", the WD45, the D17, and other later models of the AC tractors and most other pilot bearings in more modern engines.
Comment - If you really want to use a wick (which is notorious) for passing excess oil and causing (oily) clutch problems, I will try to find one for you that I may have "left over" from one of my gasket sets. I think that to properly install the "wick" you will need a "puller" (made like a small "chinese finger trap") to pull the wick into and through the hole without damanging it. I have not seen such a "puller" in over thirty years. Someone on this forum may know where to get a "puller" of this type. I have NEVER used a wick. I think that there are many very good reasons that AC stopped using the "wick" many years ago, and that very few other companies ever used the "wick", and that no company uses it now.

Gordon : could you explain what you mean by staking. Also would the bearing that comes with a clutch kit work, or are you refering to a different kind of bearing (seal on one side).

My understanding is these were just cotton wicks like the braided ones for lanterns. When I went looking, I couldn't find one in 3/8" round. Ended up using 3/8" cotton 'piping' cord form the fabric section of Wal-mart. They use it for sewing decorative cord on pillows and such.
