I'm doing a tranny rebuild

73 914, the synchros are shot. I cant shift into 1st 2nd or 3rd without grinding, 4th is ok and so is 5th. I adjusted the cable and its doing the same thing. So it isnt the cable. I have the Hayes manual but I dont feel the 'installation is the reverse' comments are enough to help me.
What, if any, other manuals exist for this type of tranny and what special tools would I need?.

Thanks
Steve M

One special tool you will need, if my memory is correct, is a 30 mm deep well socket. This is needed for the removal of the speed-o gear.

Also, count the number of gaskets between the back cover and the middle plate.

You might want to consider new dog teeth for first gear.

Good luck.

Steve I have had a couple of these transmissions apart for myself, and two friends in the past 3-4 months. If you need further info give me a call after 8 eastern (I'm in Northeast Pa) I'd be happy to help. Study the 1st gear rebuild article on this site as a first step though.

Tools - 30MM Socket, Heavy Duty snap ring pliers, to get the brake bands off. There is an alignment block made of plastic to hold the gears and shift rods in place while you set them up, check with Tom at Pelican he can get it for you. AND a willing trans guy to eyeball the gears and dog teeth to tell you if too much wear has taken place.

Update on the trans. I was driving the car to the garage where I keep it on my way to work. Now I have to search for 2nd and its even worse in 3rd. But I may be at fault in that department, at stop lights I used to keep the shifter in the 1st position notch. You know, where the spring action is. Without actually putting it in gear, I think that may be the cause. Just as soon as I weld the elbow that keeps my engine lid on, I pull the trans. Possible in about 2 or 3 weeks. Thanks guys for the input.
Bill, I will definatly be calling you.

Thanks

If you rae having trouble *finding* the gears, then the linkage might be at fault. It may be worth replacing the bushings and so forth (look for "shifting improvements" tech article in the 914 Tech Articles section of this site) before tearing into the tranny.

If you're doing 2-3-etc. gears/synchros, then you'll have to remove the intermediate plate. Chances are good that the ball bearings in the plate are shot, and you'll have to replace them. They're over $100 each as I recall. 8^( You also have to VERY CAREFULLY measure the thickness of the gasket between the intermediate plate and the tranny housing--that is what sets the gear lash on the ring and pinion! You have to add some amount for the "squish" of the gasket, and I have no idea what that is!! With luck, whoever you order the parts from (maybe Pelican? Hint, hint...) will know how much to add.

GOOD GOD MAN!, are you implying that I would order my tranny parts from somewhere other than Pelican Parts!. You have insulted my sensibilities, good day.

Seriously, a hunerd bucks for bearings, looks like I'll be digging a little deeper into my pockets.

I had replaced the cup bushing and the bushing at the point of entry of the rod (is this too pornographic?) at the shift housing on the tranny about a year ago.
But I didnt replace the one at the firewall. Either way I have to get into the tranny to replace the synchros.

Thats $100 for each of the TWO bearings. Don't forget to replace 1st (and probably 2nd) gear dog's teeth. While your at it, check the slider for 1st. If it is badly worn the new syncros will not help problems going into 1st at a stop. Finally, I think the intermediate plate gaskets come in three standard thicknesses and are included with the gasket set.
