mattd860 162 #1 Posted February 7, 2013 I was using my 1963 753 today and while traveling in 1st gear all of a sudden the shifter became really loose and I could not shift out of gear into neutral. I'm able to move the shifter all around but cannot get out of 1st gear or into neutral or another gear. I'm going to have to open up the transmission at some point to see what happened. Any guess? What should I be looking for in there? Share this post Link to post Share on other sites
TT-(Moderator) 1,129 #2 Posted February 7, 2013 The very first thing I would do is loosen the set screw & remove the shifter. More than likely, you will need to make a custom hex key ("Allen wrench") by cutting the short end even shorter. Inspect the shifter pivot ball for a broken roll pin and make sure the ball at the end of the shifter is still intact. Once the shifter is removed, you can use a screwdriver or similar tool to move the shift fork back to neutral. (centered) If the shifter is fine but the fork won't move, you'll need to split & diagnose. 1 Share this post Link to post Share on other sites

stevasaurus 22,295 #4 Posted February 7, 2013 Sometimes, if you loosen the hex nut, the dog point set screw may back out with it. :) Share this post Link to post Share on other sites
TT-(Moderator) 1,129 #5 Posted February 7, 2013 Sometimes, if you loosen the hex nut, the dog point set screw may back out with it. It's always better when that happens. When installing the shifter, I hold the set screw until the jam nut is tightened - or it ends up turning with the nut and getting too tight. There is very little room to work through the hole in that style of hoodstand, so I shortened a hex key - instead of mutilating the hole in the hoodstand like some I have seen. I usually remove the seat & spring too. 1 Share this post Link to post Share on other sites
mattd860 162 #6 Posted February 7, 2013 How much gear oil do these rear ends take? Share this post Link to post Share on other sites
rmaynard 14,986 #7 Posted February 7, 2013 1-1/2 quarts Share this post Link to post Share on other sites
stevasaurus 22,295 #8 Posted February 7, 2013 90wt...like Bob said, but to be accurate...fill until it runs out the plug hole beneath one of the axles on the back of the trans. It is on the right in the early trannys, but may be on the left. :) Share this post Link to post Share on other sites
mattd860 162 #9 Posted February 8, 2013 It's all fixed. The shifter is still in great shape but somehow it fell out of the 1st gear and reverse forks. Once I took out the shifter I was able to realign the forks in the neutral position and reinstall the shifter. I even changed the gear oil while I had the seat off. Thanks again for all the help! 1 Share this post Link to post Share on other sites
