Ken,

I was wondering whether the two parts were not electro-welded. Thanks confirming it's feasible without exploding the stuff.
I understand your method.
But there again the effort will have to be supported by the spring clip and the thin lip that maintain it.
That's true that this effort will be more evenly spread all around the spring clip.
I'll try it. I have to figure out how I can fabricate the needed hub plate with the limited tools I have in hands
Thank God, I have the press.

I used a "bearing puller" I got at the local Harbor Freight in conjunction with a press. Much better ones can be had elsewhere. These are the $30 snap ring pliers I got from the snapon truck. Worth every penny!

I used the exact same Harbor Freight bearing press as you, tomp. It does the job. It costs $9.99 or $19.99, I can't recall which.

Hi steve, Can you give more info about the Dog gears you bought. Were they new or had they been reclaimed from another transmission. If new I would like to determine the source.

Hi Ken yes the dog gears were new and I had them fitted by the same supplier.I think they were around AU$100 each.He is a well known alfa supplier in Australia especially in the rally and race car building area.

Hi steve, This is the first time I have heard of the dog gears being available new. Here in North America we have been canibalizing other gearboxes. While I knew that similar dog gears were available for Porche after market not for Alfa. So this is good news. As their web site is not up and runnibg can you get any further detail from avantri.

Thanks for clearing that up for us. Too bad the answer didn't go the other way.

reviving this thread to seek advice

Is it possible to change a second gear synchro in the Alfetta gearbox without completely removing the transaxle from the car? I am about to change all the driveline rubber in my Alfetta GT and am considering addressing my grinding second gear issue as I will have many of the necessary removal or disconnection steps accomplished anyway. The shop manual clutch assembly removal section depicts the clutch-gearbox housing and intermediate flange removal process with the transaxle still installed.

G'Day Jim,

Yes, as the manual says it's possible but what has always worried me is sealing the flanges, seems to me that there is always going to be a drop of oil run onto the flange just as you put it together.

It (the removal) is also depicted in the gearbox manual on my site.

Hello:
I wanted to update this very useful forum on my recent experience in removing the dog gear on my 1985 Spider first gear (to do the First Gear Fix). I have the Harbor Freight 12 ton press and the Harbor Freight large bearing separator as shown in Post 32. When I put back on the snap ring I only hand tightened the bearing separator; as a result when using the press (using a 32 mm socket) the snap ring was just deflecting. I then tightened the separator with a wrench such that more of the load is carried on the dog gear. I put it back in the press and started pressing and it looked like nothing was getting lose. So I pulled the assembly out of the press and on the back side it was starting to separate (inexpensive press does not truly press perfectly straight down). I rotated assembly 180 degrees and it then pressed out nicely (put a wooden block under the gear to catch it). The trick was to tighten up that bearing separator on to the dog gear.

Thanks.
