Can't get any gears - ER-5 kawasaki Motorcycles

The derailleur mechanism, as its name implies, 'derails' the chain from one rear sprocket to the next, either larger (for a lower gear) or smaller (for a higher gear). It is spelt that way as it is a French invention.

All the gears inside the transmission are driven off a main gear called a cluster gear. Though the gear ratio changes as you select different gears, each "gear" you select engages several gears inside the unit to achieve the one you selected. Actually if it was possible to have a straight through arrangement, that would happen in fourth gear. Fifth is overdrive... the input actually turns slower than the output so the engine turns slower and saves fuel.

Hi,

This might be because of the gear box problem. By any chance, did your car face flooding? In such cases, please drain the gear box and replace it with new gear fluids. Also, check if you go in low speeds, you might be able to engage it with ease. Please come back to me if you feel this doesnt solve your issue.

Regards,
Hari

The kick shaft gear, idler gear, and clutch drum gear on the 1985 xr250 and below are smaller tooth gears than 1986 and newer. I have an 85 and an 88. I had to replace the 85 kick gears 3 times. The last time I replaced them I found that the larger gears on the 88 fit as long as you replace only the gears. The kick gear comes off the shaft and the larger tooth gear fits on the shaft. The larger idler gear fits where the smaller tooth idler was and the drum gear comes out and the larger tooth gear will fit there. Or the drum you have with the larger gear will now fit the other gears. This is a better solution than finding another drum with the smaller tooth gear because the smaller tooth gears will not last. I hope this helps.

closest I have is 94 explorer. may be similar.

A broken gear tooth will cause a clicking sound. Start out in 2nd gear going slow. Hear any clicking? If so then TWO gears need to be replaced > the broken gear and the gear that meshes with it. If enough pressure was on a gear tooth to cause it to break, then similar pressure was on the gear it was engaged in. The gear may look okay, but it isn't. ALWAYS replace gears in sets.

Please rate this answer. Thanks John!
