hey guys, i just put my '88 Si tranny back together. took it apart to replace some bearings. All went well but i was left with one extra part, its a thin washer almost 1.5" in diameter and it looks to be a spring washer of some sort because it is bowed. the tranny seems to go through all gears ok and everything moves good. does anyone know where this might go? btw i never took any gears or synchros off the shafts, took shafts out as an assembly and put them aside. i think maybe it might go in the hole that the mainshaft drops into but i'm not sure, any advice, how important is this thing. should i rip it all back apart or no

 

It is probably a thrust washer that the mainshaft goes into, it is necessary to maintain the proper clearance in the trans. I bet you would run into problems if you didn't put it in there, and the ISB would probably wear out pretty quickly.

 

damn, thats where i thought it went, aight guess i'll pull it back apart. lol fun times

 

there is another spring washer that is on top of the bearing at the back of the countershaft, just below the nut

 

i never took the nut off the shaft, i pulled it out as an assembly so that would rule that washer out right? i'm pretty sure it has to go in before i drop the mainshaft in, i just looked at a diagram on majestic honda.com and it says there's supposed to be a 36mm spring washer there, i think thats its. thanks for the help guys
