Use red loctite and snug up and bend the locktab over. It does not take much to snap the head off.

eas The fork/syncro sleeve are measured and placed equidistant from the dog gears on each side and the fork bolted to the rod. The 5th fork/syncro sleeve must be 12.9mm from the face of the dog gears as shown below

eas The main assembly went in the casing for a trial fit to make sure the rods are in the right position. I had to temporary close the two half's together to flip the case upright to be able to put in the 3 ball bearings, springs and bolt in the retaining metal plate. This will hold the rods in place for measuring the fork position later.

The retaining metal plate will be removed again to put some RTV between it and the case.

eas I did not anticipate how frustrating it will get to get those 3 beans into position. But in they went, starting from the bottom all the way up to the top topped with some assembly lube.

eas The main shaft was fully assembled, axial play and distance between 3rd and 4th teeth measured. All in order.


Here is the final product

The seal glided over it with near zero drag and the tape came right off afterwards. Do not put tape beyond the spline because it will be obstructed by the tube covering the input shaft.

In that other thread somebody suggested filling the input shaft seal with grease to keep the spring in place. My thinking is that I would rather see what is going on so I did not do this. Sure enough, one side of the spring rode up on the inner lip of the seal but did not come completely out. I could easily flick it back down in place with a screwdriver. I would not have seen this if it had been covered with grease.


Thanks for the advise.

eas I forgot to tell you folks that I also got a bearing set, 5th fork, seal for the speedo cable and a magnetize sump plug.

All parts have arrived and assembly time will start tomorrow

eas Update:

After a month waiting, I had lost hope that the 2 dog rings will ever arrive. In the mean time, I had a short business trip to the States and while there I asked the seller (against payment) to send me a second set to the hotel I was staying in. On the same day the parts arrived at the hotel, I received a tracking update on my first shipment that it has arrived at my local post office. On my return home, I picked it up and now I ended with 4 dog rings

eas I am not sure what to do at this point. Still waiting for the two dog rings to arrive.

From the tracking number the package seems stagnant since the 4th Sept. The vendor replied to tell me it is not in his control, and there is nothing he can do from his end. Quote "there is really nothing we can do at this time because 1) the tracking number is still active and 2) it shows that it is still in transit to you (the destination). If something changes we can initiate an inquiry but we cannot do anything beyond that."

Gearbox is in pieces and the only work I can do is to install the bearings on the lay shaft, and the direct drive shaft (4th gear).

exhausted Speaking of bad service I purchased a spring on EBay for the horn contact on my Sprint gt that was on August 7 he emailed me two weeks later and said the springs are tangled up in a box ten days later I receive message untangled, another 8 days go by and then I am told it will be posted today what do you do? it will be another two weeks in the mail, I couldn't find the spring anywhere else good thing it is a long term project.

I only had great service from Alfaholics and ClassicAlfa. Both are exceptional. 2 days and the parts are at my door step.


I wouldn't wish to bad mouth vendors on a public forum. It's the first time I am buying from this vendor and I am very disappointed with the postage costs Vs postage service. Never again unless I need something only this vendor has.
