5th syncro rebuild. Need Help

racerxrx7 · 01-07-05, 01:46 PM

I'm changing my 5th gear syncro and I wanted to have a leg up on the replacement. Does anybody know where I can find some pictures or write up on the whole process. Also, any special tools that I might need to facilitate this job.

Thanks

I bought the syncro for $15 from Mazdacomp add in a few seals and it totalled up to $28 or so.

I took the trans out to my local tranny shop and they charged me $166 to install it. I probably paid on the high side to replace the 5th gear syncro but I had the tranny back in 3 hrs so I was happy

the job can get expensive quickly depending on how much the syncros on the gear and hub are worn.

i think i had 300$ in just parts to put mine back together

If you get stuck at any point, I can provide some extra pictures. I took a boatload so far in my tranny rebuild.

I bought a jspec tranny to replace my stock tranny with a bad synchro...do you guys think I should replace the synchro in the jspec tranny just to be safe...I mean I really don't have any way of knowing the condition of that transmission. Is the job easy enough where it would be worthwhile even though that 5th gear may be fine? I've never dealt with any type of transmission but am pretty mechanically enclined. I already have the synchro as well

I'm planning to do my tranny also, but was wondering if anyong could tell me what size the nut is that you have to take off on the gear cluster. Just want to make sure I have the socket to make my job a little easier.
Thanks

1-1/4". Buy a new locknut. Also, take off the 5th/Rev clutch sleeve - if the teeth are worn and slightly sharp to the touch, it needs replaced. Fortunately you can buy the sleeve without buying the rest of the clutch assembly.

Easy Job to do with a buddy, Make sure you have the long Bearing pullers and Make sure you buy New Bearings They have been upgraded from Mazda TOO !

It's Kinda Like playing JINGA !

Take it apart in order and put it back together in reverse order.

I wanted to thank everybody with they're input. I partly have the syncro changed. I found the rear bearings needing replacement. I ordered them today and hope to have them for tomorrow from Malloy Mazda (Ray Crowe has been great in helping get the parts that I need.)

I hope to have some pictures for you guys.
