new shift shaft?

esworp · Jun 30, 2008

My shift shaft on my 1978 dt205 project is bent.. mebbe about 5 degrees right at the narrowing part 3 inches in from the splines.

How crazy would it be to heat up the bar with a torch and try and bend it back?

Barring that, anyone have one to sell? Speed and Spend has them for 80 bucks, which feels a little pricier than I'd like.

the only reason I need to fix it is that the oil seal is opened up at this angle, and the crankcase oil dribbles out. Part of me just wants to goosh a blob of rtv sealant into the hole. :|

If you knew a machinist, there are center marks in that shaft. Put it between centers on an engine lathe and true it. 60 to 80 dollars.

The part is no longer available from Yamaha.

Straighten it like foxforks said.

You don't have to heat it. Just put it between centers or on V-blocks and spin it to find the high spot. If you don't have access to a press you can put it in a vice with aluminum jaws and place a piece of pipe over the bent end and bend it back until it's straight. Then re-check it in your V-blocks. You can make a set of V-blocks using angle iron.

I took it to a local machine shop, and the guy did just that. He did a great job, too. I was very happy.

And he didn't charge me. other shops wanted to bill me $35 for an hour's worth of work. yikes.
