I have all the gears.
Ya going to call me?. ..............lm

I took a break from spending money on parts today to clean out the lower crankcase, which was pretty filthy. In the muck, I found a sheared off gear dog, which made me give the transmisson shafts a closer look. I already knew that 1st on the secondary shaft was bad, but only because the kick start teeth were worn. Sure enough, I found that 1st & 3rd on the primary and 3rd on the secondary shafts were missing half of their dogs. Where the other broken dogs disappeared to, I do not know, but now 4 new gears are needed. A bit disappointing, but certainly not the end of the world. It really wouldn't be half so fun if everything was easy.

Also send me a pic of the shift drum so I can see the pointed end in the roller slot. .........lm

Will do, LM. I’m almost done cleaning the lower crankcase and will get to the transmission next. Probably tomorrow.

Thank you, rrekr, I think you might be right about what I'm seeing. My knowledge and understanding of the transmission is limited at the moment. I've only been into one other. I'll be studying it more today. Right now, I believe that the 1 dog I found in the bottom of the case is from 4th on the primary. I've also found a gear tooth, but I don't see one missing on any of the gears. I suspect that someone else has been into the transmission at some point in its life and has replaced the gear that the stray tooth came from.

Hi Seadog
The sliding gears had six engaging dogs while the fixed gears had three. Is that what you are seeing?

Email sent with photos, LM. Thanks!

Thanks, Geoff. The stand has good and bad points. I might try to come up with a slightly different design someday that engages more than one set of engine mount locations. It really depends on what I decide to do for 305 projects in the future.

I like the engine stand John, I was too lazy and just used two blocks of wood. If I have to pull the engine apart again I'll make a stand similar to yours.

Please turn the part on the right over. ..............lm
