My wife's '73 was leaking a huge amount of oil out of the speedo drive. I contacted McMark to try out his newly designed speedo drive.
As you can see, this drive was leaking quite a bit. Just sitting in the garage it would drain out a major spot just in a couple days. (IMG:http://www.914world.com/bbs2/uploads_offsite/i171.photobucket.com-179-1269017475.1.jpg) Here is my core sitting next to the new unit. Notice the extra O-ring: (IMG:http://www.914world.com/bbs2/uploads_offsite/i171.photobucket.com-179-1269017476.2.jpg) The swap was straight forward. The only difference I noticed from a regular speedo drive was a little persuasion required to very lightly tap the drive into position. I just used a small rubber mallet to accomplish this. I am confident that I did not pinch the O-rings, and it felt like a good solid seal. Once in place without the set screw in, I could not wiggle or move the drive from side to side at all. A quick fill of the trans: (IMG:http://www.914world.com/bbs2/uploads_offsite/i171.photobucket.com-179-1269017477.3.jpg) A quick wipedown to get rid of any oil: (IMG:http://www.914world.com/bbs2/uploads_offsite/i171.photobucket.com-179-1269017477.4.jpg) Also put a strip of cardboard underneath the trans...I want to make sure this isn't going to leak. (IMG:http://www.914world.com/bbs2/uploads_offsite/i171.photobucket.com-179-1269017478.5.jpg) I will snap another picture underneath in a couple days. I highly doubt that this will leak at all! Such a good idea IMO...I wonder why no one thought of this before! |
