Will do.
I plan to weld the gear to the shaft with the trans in the car. The old gear came right off, so I'm thinking the new gear will go on somewhat easily. I am going to use the red Locktite along with this method. I've considered trying to drill through the two surfaces and install dowel pins instead but I need to see how that would go. I don't think this is a good option but I may give it a try. While I'm in there I might try the mod for better oiling too.DirtySouthJacket gave me his fifth gear puller when he sold his car.
I have not inspected it, but think it is a standard puller with the jaws ground down.
If you have your case apart you might consider this as well: fifth gear improved oiling
If I'm not mistaken doesn't the smaller gear in the .658 set equate to *lower* torque loading on the output shaft? It's spinning the output faster, with less force, right? Or is there something else I'm not considering here?You will wreck that gear if you install it on that shaft , even with loctite.
That gear is taller and will encounter more torque loading than the previous gear, loctite is not enough to compensate for the spline wear.
I would find another good used transmission, tear it down and replace the output shift or continue to drive in 4th...
If the Output shaft gear is larger, then yes, torque will be reduced. I tought you went with taller gears.If I'm not mistaken doesn't the smaller gear in the .658 set equate to *lower* torque loading on the output shaft?

Either way, your point is still valid and it's exactly what I was afraid of: my output shaft is too far gone. Turns out the shaft I need is an 0A4311205E or 02J311205N, which both run about $350 everywhere I can find them. So, rather than go through the pain of tearing all the gears off my shaft and putting them on a new one, I took your advice and found a cracked GQQ and I'll just yank the output shaft outta that and drop it in mine. Replacing the bearings should be...fun?
The 660 is made for splines and gears. It is also made to fill small area. Did you try this one at all?Yes I did. No you should not. See my first post.
It lasted around 23k miles for me, however when it failed, it wore the shaft even more to the point that I had a concentricity problem with the new gear. If I had used red from the start, I wouldn't of had to fix it twice, get another gear and the first time there was still enough engagement with the new gear and old shaft that the gear still went on with little slop. again when it failed after the green.
Just use the red loctite. There is no benefit to trying another type. You can still disassemble the gear later by heating the loctite.
you won't lose too much in terms of mpgs. maybe 1-2 but you will miss that 5th gear on the highway. i drove mine for about a year when i lost my 5th and putting in the 6 speed.Bumping this thread as it has some useful info, and I have same problem. Small gear wiggles on shaft when I took bolt out. I think I will have it welded for now or just drive it in 4th and see what my mpg's drop to...
