I've been working on the 5th synchro replacement, and it was going smoothly- took everything apart per dgeesman's writeup and found a broken 5th synchro. I replaced it with a new one from malloy mazda and I just put on the 5th gear and the little silver ball&washer.

Now, when I try to slide the lower set of c-washers into the groove that is just above the silver ball's washer they will not go in - it's like the c-washers are too thick or the synchro+gear+silver-ball-washer is about a mm too high... any suggestions? Is it supposed to be a tight fit? should I try to force the c-washers in their groove or try to press down the 5th gear? I'm pretty sure I put the synchro on right and I took care to align the gaps with the gaps on the hub. When on the synchro would only rotate a few teeth distance in either direction. Also, it was difficult to get the little ball to go back in to its hole in the mainshaft.

Anybody else ever had this problem? have any suggestions?

hey little cat i was just wondering...im gonna have to do that my self here in a little bit...could you possibly add some pix to this so we can see what our talking about ...i like to kinda learn from other peoples experiences... also on a side note...what ship are you attached to?

there should be a pretty loose fit with the c washers, they slide right in and out.

lilroach

is this the c-washers above or below the main bearing? if they are above, the bearing may not be fitted down far enough.

thanks for the replies - it was the c-washers below the main bearing and above the 5th gear.

I went back and managed to get the little ball out again(not easy after I had more or less jammed it in) and took off the 5th gear and synchro again. I put it back together again and this time everthing went together with no problems. I guess I just didn't have the synchro seated right....so, for those of you who are planning this in the future, the little ball and c-washers above it should fit in their respective hole/grooves easily and with no force.

I'd post pics but I don't know how to upload pics to this website...

Anyway, it sounds like you have things sorted out. When you place 5th synchro, note the 3 pockets in the ring and the keys in the 5/R hub. The pockets fit over the keys, and thus limit the synchro to rotating a maximum of one-half dog tooth in each direction. If the ball/ring don't fit, it's because the assembled parts underneath it aren't fitting right. The c-washers should slide right in with very little clearance, but not a physically tight fit.
