This is a “How to” on replacing the worn shift linkage bushing for the 69-72 tail shift 914’s.
I picked up the 914 Shift Bushing Super Kits form Pelican Parts http://www.pelicanparts.com/catalog/shopca...t_pg1.htm#item0 Parts needed: 1 New Ball Cup Bushing 3 New Firewall & Shift Rod Bushings 2 New Shift Rod Bushings Tools I used: 10mm socket 12mm socket 13mm socket 2-13mm open end wrench 4mm, 5mm Allen keys 1 flathead screwdriver Grease for bushings Paper towels Magnetic pickup tool (not needed but helpful) Needle nose pliers Jack & jack stands or ramps if you can in reverse 700 Tech Book & Haynes manual When my 71’ 914 arrived it started but would not go into 1st or Reverse. I was told the tranny needed some help from the previous owner. First thing I did before buying the 914 was order & read thru the 700 Tech Tips by George A. Hussey. Great read and a must for 914 owners, pg. 48 #344-352 was very helpful in solving the tranny issues I had. 1st- The tranny would not go into reverse, but it felt like it was going into 1st or maybe 3rd I couldn’t tell do to how loose the stick felt. I knew that the shifting bushing needed to be changed (the car is 39 years old). Now for the fun: Jack up & support the car with two jack stands or if you can use two ramps so you can get under to remove the shifting rod and to replace the bushings. This is what I found: Tail shift mechanism has lost its cover & some rubber things are around it. (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280811789.1.jpg) This is the cover that houses the two ball shifting bushings. Look at what’s left of the boot.

To remove the Ball Cup Bushing holder use a 4mm or 5mm Allen key, when the retain screw is remove push out the Ball Cup Bushing holder with a large flathead screw driver or if you have one a chisel and tap it off
(IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280812099.1.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280812101.2.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280812102.3.jpg) Pop in the new shaft bushing add some grease and slide back over the shaft. (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280812104.4.jpg) Next "The ball cup must be snapped onto the shifter ball while outside of the cup (to allow room for expansion), then the shifter with bushing is inserted into the shift rod head." thanks Jwest. Add some grease to the ball cup before snaping into place and add some grease to the holder. (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280877937.1.jpg) Now slide the ball cap bushing holder back on the shaft, locate the small hole for the 4mm or 5mm Allen bolt and tighten. (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280812109.6.jpg) Replace the shifter base, make sure you slide in the ball cap bushing into its holder and bolt the three 13mm bolts and two 10mm bolts. (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280878653.1.jpg) Next you’ll need to remove the selector shaft rod form the car to replace the firewall bushing (thin red line) and the ball bushing on the selector shaft rod (thick red line) (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280812112.7.jpg) Between the seats under the tray/third seat is a black access cover remove, I used a Philips screw driver. (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280812113.8.jpg) Use a marker or something to mark the locations for when you put it back. (It’s a reference point for reassembly) Next loosen and remove the 13mm nut and bolt. FYI the retain collar will not slid off without the bolt removed, it has a notch for the bolt don’t try and force it off just remove the bolt & nut. (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280812115.9.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280812116.10.jpg) Next go back under the car and pull out the shaft. With the shaft out pull off the ball. I use a vise and pliers for both. (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280812118.11.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280812119.12.jpg) To replace the new plastic bushing ball I first greased the stud and put some grease into the ball, then I gently used my 3lbs hammer to pop the ball back on. (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280812121.13.jpg) Now with the new ball bushing in place, replace the old firewall bushing and put back the selector shaft, add a little grease when sliding it in. (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280812123.14.jpg) Next slide the shift rod back under the engine mount and put it back into place, (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280813201.1.jpg) Pop the rear of the shaft onto the tail of the tranny and tighting the two 13mm nuts and put back on the ball bushing cover. (IMG:http://www.914world.com/bbs2/uploads_offsite/i494.photobucket.com-11882-1280813202.2.jpg) Now attach the shafts line up your earlier marks, replace the nut & bolt then tighten At this point the bushing replacement is completed you should now make adjustments to get the teener to shift like new. After completing the bushing install the shifting was much tighter. I hope this "How To" helps anyone interested in replacing the shifting bushings. |
