So a couple weeks ago I blew out the sector gear on the 448. Turned out the pivot shaft was wonky to begin with, making matters worse.
Middle 4 or 5 gears were the worst, but a few on either side were worn hard as well. For whatever reason, the R. side of things got the most hurt.
Broke out the MIG, then the TIG, built the gears back up, got out the files, and made it work again.
The pivot shaft is now bolted tight to the frame ( for however long, not welded ) and I built up a rather , ummm, unique washer system and jamb nut configuration to keep it all in place.
Lash is nice, no binding from side to side in turning, and hopefully the new gears hold . Full turning radius , I think even better than before.
Whatcha think, worth more than the 10 buck gears on e- bay? Prolly cost more to do this than get one of them, but I like fixing what I have. More TIG time is a bonus too.
Oh yeah, the cast bearing section was broke off too. Sorry about the cold looking welds there, trying to save the cast as much as possible, that is a road less traveled for me.
