Well bad news is yes to replace shaft you do need to split motor
But I have seen a few solutions that are a bit back yard mechanic jobs but they work !
you could tap and thread a small bolt into the the gear lever 90 degree's to the shaft then it has something to tighten down on the shaft
I have even seen guys put a spot or two of weld on the end so you can reach it to grind off if you need the lever off again at any stage
Some gasket glues can work also if you still get could tight grasp from just tightening the lever on the shaft then some good old gasket glue can be enough to increase diameter of the shaft to get even better grasp from the lock nut and when it sets also helps with securing the lever to the shaft and unlike glue it never sets rock hard so you can always get it off again if you need to

does the selector drum rotate ok and is the gear selector shaft that the gear lever goes on straight and not tight in the crankcases.and have you checked the bearings on the input and output shaft are good.

Just lost mobility of my gear box, bars com loose on gear box a pin that holds gear box drive shaft in place


replace the long shaft in the right lever and use a split pin to hold it in pace . There was probably a rubber grommet in the hole and the lever would have had a flat washer on either side with the split pion to hold it all together.

Shift shaft is broken. Do I need to split the cases to replace it?


Whether it is a four stroke or a two stroke, If you take the right crankcase cover off you should be able to access and replace the shift shaft. The mechanism is on the opposite side of the motor from the shift lever. You may have to remove the primary gear that contains the clutch pack to get the actual shift shaft assembly to slide out. The good news is you should not have to remove the engine from the frame or split the cases to do the job.

I am having trouble trying to split my engine case. I'm am trying to split the magneto side, I have all bolts out that I can see but still it won't come off, is there something inside the other side of the...


I don't know what has not been removed so pardon me if I suggest something already removed. Remove the cylinder, intake manifold, magneto, stator, sprocket and shift lever. A case splitter is highly recommended. They don't cost that much and it makes for a clean separation. The two positioning guides will tend to hamper separation as will the crankshaft and output shaft as they slide through the bearings. That's another reason for a case splitter. Now would be a good time for new crank and output shaft bearings and seals and a new shift shaft seal. I assume the reason for the teardown is either a bent shift fork or broken gear teeth. If replacing a gear with a broken tooth or two, also replace any gears the broken gear meshes with. If you don't, you will get to do the gear repair a second time very soon after the first ride. Whatever pressure broke the teeth on one gear was also present on the meshing gear. It may look good, but it isn't. Please take a moment to rate my answer. Thanks.

Makes noise when on but the blender doesn't turn.


It is most likely a stripped gear. Here is a link to the parts manual which contains the listing of the gears and shows you how to split the gear case.

http://shared.whirlpoolcorp.com/assets/pdfs/literature/Repair%20Part%20List%20-%208212057.pdf

Remove the chrome ring with a screwdriver by prying it off carefully. This exposes 5 screws, however they can't be accessed on all models. Remove the pin (17) that goes through the planetary housing and the drive shaft, and carefully drive the planetary housing from the shaft to expose the screws. Then remove the 5 remaining screws and split the case to expose the gears. The worn gears will be obvious.

Also check the bearings. Replace all affected parts. Remove all grease since metalic pieces will have contaminated it from any worn out gears. The grease is a special food grade grease which you can purchase along with the gears and bearings.

KitchenAid food processor makes a grinding/clunking noise while running. (Not supposed to be there.) Sounds like gears not aligned.

Blades won't turn - motor seems ok


It is most likely a stripped gear and most likely the worm gear which is driven by the motor shaft. Here is a link to the parts manual which contains the listing of the gears and shows you how to split the gear case.

I dropped my 82 CX 500 and snapped off the gear shift spindle - not just the shift lever but the shaft which the gear shift is attached. Any suggestions?


The shaft is pretty easy to replace. Just remove the right side casing and then the clutch and then the shaft is pretty much ready to pull out the right side. The shaft can sometimes get bent on a fall. cut the shaft nearly flush with the casing if it is bent. The bigger problem you will likely face is a bent shift fork or two. That would require pulling the engine and splitting the center case to replace the forks. Unfortunately the chances that a fork or two has'nt been bent are pretty slim. The bike will not shift properly with bent forks.

Clutch will not disengage


Chances are the clutch lever assembly (where the cable attaches to the gearbox) has gotten out of position on the Axle push lever (the shaft that goes into the side cover and the lever is attached to). The shaft is splined for the lever to attach. Re-fit the lever on the shaft and try it now. If the splines are stripped then you may need to drill a 1/8" hole through the lever and shaft then insert a 1/8" cold roll split pin to anchor the two together.

The bottom of the axle shaft fits in the side cover and actuates a lever to separate the clutch plates. This mechanism could be bad.
If that is the case then get the entire COVER ASSEMBLY part number 5NY-15490-00. The assembly comes with a new shaft.

The clutch cover mount bolts should be 8 to 10 ft. lbs. This is not a factor in your problem.
