1974 250a pawl holder was created by Northern hunter

while riding the trail bike the other day into some ugly stuff i noticed shifting was acting funny although I could still feel the clutch opening. After making it to the top and made it down to the hills, on the way though I pulled the clutch in and downshifted like normal and the shifter got stuck at the bottom position after making it back. There was no grinding sounds or anything coming from the transmission, almost like it just got stuck in neutral. I got home and drained the oil and took of the right side clutch cover to find that the pawl holder had snapped. My plan going forward is to pull the side off and have a local welding shop weld the pawl holder back into place. My only question is going forward is there anything I need to know specificly when taking this apart and should I replace any bearing or oil seals while I'm doing this or leave it as is sense the engine has been running fine.

Interesting how weak the case looks in that area when something breaks out of it. In fact i've never seen it happen. Seen just about everything but not that. Generally i'd imagine it'd need a hell of a good hit to cause id, like smacked on a rock from a sizeable crash/accident. If you landed on a rock it'd be bent the other way by lever going up. Or did that happen then you changed down to find a gear so ends up pointing forward. Regardless, she a welding job for a skilled welder.

Can't say I've ever seen that either. 

On what you replace is up to you and how far you need to take it apart for your welder to fix it properly. 

I'm a fan of leaving things alone...  but I would pressure/vacuum test the engine to check crank seals before buttoning back up.

That is a very good point that you mentioned RT3 about it hitting a rock causing it to loosen the metal and then it fully cracked after I shifted down. Cause there was some large rocks that i had went over and was possible also when I posted the original problem to a TY facebook page they seemed to happen more frequently on these bikes. Even the crank cases on ebay have been welded in these same spots. 
Also thank you MarkT i will look into that Thanks.
