Getting ready to tear into the front half of the transmission that was on my 57 3100 when I bought it. I have great pics from the manual that walks you through the repair of the overdrive section, but the service manual is a bit sparse on tips and tricks for the leading half.
I still have the adapter plate in place while I check with you fine folks to get your recommendations, tips, tricks, and "I wish I woulda's." I think I can do this, though I have minimal mechanical skills.
I have already looked at the tailshaft bushing and found it scratched up, so got the bushing for that. Here's what else I found that needs addressed:
-The 1-R slider gear has a good number of teeth rounded and some that are nearly halfway gone. Got a replacement for that.
-The countershaft assembly middle gear set was chewed up, nicely matching the damage to the 1-R slider gear. I sourced a NOS part that set me back $150. Ouch.
The sm319 rebuild kit I bought seems to have everything I need, but not everything seems to match up to what I've pulled so far. For instance, the access hole plug at the top of the transmission is about 1-1/4 inches. The one in the kit is about 3/4 or one inch. I bought a 1-1/4 inch freeze plug that I think will work for this, but wonder what else I will find. I haven't disassembled the 3-speed section yet, so will report more anomalies as I find them.
Do you use permatex on the paper gaskets?
In researching here, I have found that folks sometimes have issues getting the front bearing out. Any tips on this?
Anyone do a comprehensive photo walk-through of the entire procedure? Would love to see it!
Here's the
transmission on the bench:
And
here are the internals.
Thanks in advance for the tips.
