My Tranny Teardown

[Onefast99gsx]

Use a punch and hammer those dents outward on those 2 big nuts. I didn't have access to an impact wrench at the time so i shoved a rag in between the gears and loosened the nuts. Whatever you do, DO NOT shove a screwdriver or something between the gears to keep them from spinning while you work the nuts off. There is a good chance that you will chip the teeth. Lay everything on a table in the same direction it came off. Some things look the same on both sides but in some cases, there are small differences, such as a notch or groove, etc...

You can use a penny in the gears if you want, but it has to be an old one that is still all copper because they are soft and wont hurt anything. Yep the punch will make it way easier to get the nuts off.

Yes, I used a penny once. That works great as well. Good point.

Sweet now i'll just get my hands on a gear puller and i'm pretty much good to go. I like using a rag in between the gears makes the most sense to me. I haven't ever taken a tranny apart before so this will be fun. Like i said im just trying to replace the main input shaft seal and then throw it together so i have a working tranny. thanks for the info and i'll keep you all informed!

Hey yeah I've been wondering what happened to you guys! You should stop by sometime, although my tranny is at my work in pieces :)

I have been thinking about taking apart my tranny to replace the synchros as kind of a bandaid til I can get it completely rebuilt.

I have never had a DSM tranny apart before though and dont really know what all would need to be done. Maybe someday. The 2nd gear grind really pisses me off though.

Good job tearing it apart. Most people would take off the front case and go " Holy shit, where are the bolts at !? " So props to you, for a successful teardown. Now just hope you get everything put back exactly as it was supposed to be placed or you can plan on tearing it down again :P

If that is what you think, pay someone to do it because I can almost promise you it won't go that smoothly. To replace your synchros and not fix your problem would simply be a waste of time and money. If you are into spending money, buy some nice gear lube ( royal purple 75 90 I think). That might smooth out your grinds a little depending on how severe it is. Otherwise just suck it up and deal with the grinds.

tim, you probly will need to replace your blocker rings and the syncros, possibly a few other parts too just to get rid of the grinding, but you never know until you get it apart.
