    Hello everyone,

    I'm having the hardest time of removing my small bevel wheel on my 2 cycle stroke engine? Can anyone tell me how to remove it? I try using a screwdriver, but it just turns along with the bigger clutch bevel wheel. Is there a certain tool I have to purchase? I spent a couple of hours trying to figure this out.

    Any advice will be greatly appreciated!

    There is a special puller tool that threads into the gear.

    The puller also reverses to remove the 10 tooth sprocket and to pull the clutch.

    Do you know what the tool is called? And where can I buy it?

    sounds like you can't get the bolt out - one must stick a rag between those gears to lock them together so they don't turn, then use a hand impact driver to remove the bolt - after that, the gear puller sold with some kits or available at most kit supplier sites is used to pull the gear off the shaft

    the hand impact driver is cheap at many places - harbor freight is one - google for a pic

    Out of curiosity, why are you removing the gear?

    Thank you all for the replies - I was finally able to remove the bolt, but I still can't remove the bolt until I order the gear puller.

    I'm not removing the gear - I want to tighting it up so it will be flush with the bigger bevel wheel. I've attached a couple of pictures of the problem I'm having.

    I think because the smaller bevel wheel isn't fully engage with bigger bevel wheel is the reason the clutch won't fully engage and start.

    Does anything this can be issue?

    For those folks who don't own a hand impact driver, 6 point socket used with a ratchet can work. Smacking the ratchet end with a 2 or 3lb sledge usually can persuade the nut/bolt to turn. Make sure you hold the ratchet and socket square to the bolt head.

    OK, stop.

    The bevel gear has wider teeth than the clutch gear, so may have some tooth edges hanging off one side or the other, but this doesn't affect the clutch operation. Read on this board the many posts about properly adjusting clutch cable and then the clutch flower nut. Also, you may find that the drive sprocket or the clutch is turning without turning the shaft, which will mean a broken or missing woodruff key.

    something doesn't look right about that picture they are at an angle on purpose to reduce noise try tightening up flower nut and then as tight as you can get the screw that holds it shouldn't have a problem long as you can push it in back and forth with your hands you should be good

    that gear DOES look like its hanging out suspiciously far... therefore something is more than likely up with that lil woodruff key.

    no,the mismatch in the gear faces wont affect the clutch, unless the issue youre experiencing is that the clutch is "slipping". it isnt. its that gear missing the key! if the gear wont simply push back in place with a light tap...the key is probably wedged in behind it... or the shaft/hole snuck past quality control while they werent looking (or possibly, while they WERE looking!)

    hint. experience has taught me that while its extra work... pull the rear sprocket off. that lets you push the clutch shaft out, along with the big gear. which then makes getting the small pinion gear and the key lined up without trying to throw any tools through walls after the twenty third attempt a LOT easier. not necessary...just easier. if they were straight cut teeth, different matter entirely. be thankful they arent herringbones!

    also, gluing the key to shaft helps hold it in place during assembly (they cant fall out in operation, only during assembly!)
