Turbo_Jet Sep 2nd, 02, 9:09 PM I have an old unused early M20 input shaft that does not have the small hole through the threads, near the gland nut, into the center of the shaft. Do I need to drill hole or is it OK to use as is? thanks, Joe Wally Sep 2nd, 02, 10:04 PM Is there a hole in the input, on the inside? If not then you need to drill two holes. That stuff is hard! ------------------ www.muncie4speed.com (http://www.muncie4speed.com) Gold 67 1967 Malibu, 2nd owner. 1971 Malibu, been in the family since new. There is nothing like rowing through the gears at 7500. Stick cars are so much fun they should be a controlled substance! DZAUTO Sep 3rd, 02, 1:30 AM Two questions: 1. Are you absolutely positive it is for a Muncie and not a T-10? 2. Are you abssolutely positive it is for an early Muncie? If so, it will ONLY work in a 63-65 Muncie. ------------------ Tom Parsons Turbo_Jet Sep 3rd, 02, 7:26 AM Tom, 1. yes, I think... 2. yes I need it for an early Muncie. I bought it from a guy that did not know what it was for, he had a bunch of NOS gears he got from a dealer. It is identical to the early M20 in every way -- 24 teeth, diameter, length, etc. It just does not have the hole. Any help IS appreciated... If it will help, I can post a picture tonight. thanks, Joe DZAUTO Sep 3rd, 02, 1:59 PM I suppose that it is possible that some of the very early inputs did not have the hole and later it was determined the hole was needed. Why, I don't know. I can see no need for oiling purposes because the front bearing has no seal on either side, thus, the front bearing should be thoroughly oiled from inner circulation. It may have been needed for internal pressure releif, but then again, I don't see that either because pressure can be relieved between the front bearing balls. If it's in good shape and you need one, then heck, I'd stick it in. If you want to take a shot at drilling the hole, go for it, but like Wally said, it's hard (on the surface). ------------------ Tom Parsons Turbo_Jet Sep 3rd, 02, 9:27 PM Thanks Tom, I once read a post (can't find it now) about the Supercase having a thicker front housing and bearing. This caused the gland nut to block the hole in the input and cause problems. I can't remember but might have had something to do with the sealed front bearing or some combination of the two. Guess I will drill the hole, just to be safe. --- Joe | ||
