Tomos A35 No shift

todd amundson /

A35 with newish pads 1st and 2nd. Bike just rips in first gear and won't shift into 2nd. I have tried all fluid levels with both Type A and F. Has J spring installed and shimming installed correctly.

I can ease off and sometimes bump it into 2nd but this sucks.

Re: Tomos A35 No shift

either your "stock" motor ain't making enough power or there's something up with your second gear. it'll shift to second around 10 - 15 normally. but when you say you can whine it out in first then it's probably something up with the clutch. inspect.

Take apart your second gear clutch apart. notice the wear where the spring clip that holds 2nd onto the shaft is beveling and the wear on the clutch bell, something is binding it up, rubbing, loose etc. Make sure you have all the right washers/thicknesses, location. I wanna say by memory there is a thick washer before clutchs go on.

if thats missing or the spring clip is missing i suspect something is missing,

while you got it open, clean on the inside of pads, kinda tarrry somtimes, balance, check pins not damaged, right orientation, etc.

Incorrect installation of the leaf springs maybe? Read step 5. here http://www.myronsmopeds.com/category/service/new-tomos-transmission/

Thanks I have gone through my factory service manuals on this. I have opened up the trans cover a total of 5 times. The Fluid is now at 300ml. It will shudder now into 2nd but pretty violently. I even took apart 2nd and reassembled it last night. Bumping it into 2nd has become easier too.

I don't have much Tomos trans. exper. but does spring tension control how long the 2nd gear clutch takes to contact the drum...
