Sprocket spindle stripped from plastic engine housing

Firstly what make and model is your bike,the rear sprocket should no be able to interfere with the carrier or swimming by arm ,if it is then your spindle is loose,the sprocket nuts are loose or the sprocket carrier hearing has collapsed.

I think you need to replace the drive gear. look inside the main housing. if you see white plastic shavings that would confirm the gears are stripped.

kits are available for under $25.00. don't buy the one with just the gears, get the new shaft sprocket etc.

Not a difficult repair. However, be sure to follow the instructions carefully. the position of the chain & sprocket when you put it back together do matter.

Good Luck

Use a press, your local garage or engineering shop should help.

Mr. RAGSDALE.
I do not know if you did strip the belt yet or not. If you did not,I will advise you a just easy and good way to do it yourself. String for the stripping,you just remove the outside belts and pulleys,remove the plastic covers of the timing belt. Just put on the crankshaft the pulley bolt and slowly slowly turn the engine until you see all the marks aligned. On the Camshafts the two sprockets do have the letters "E" and "I", E= Exhaust and I= Inlet.means that the inner to dashboard side is the inlet cam and to the vehicle front the exhaust cam. These two cams with the letters must be aligned,with the crankshaft sprocket
having on the side a small groove which mus be aligned with a small point ball behind the sprocket on the cylinder block. There are your marks. Loose the tensioner and remove the belt.

Good Luck!

If the one you bought is too big you need to get a 17mm centre one. 17t is the teeth and the next important bit is the pitch.

either 420 or 428. You can check by measuring how thick your sprocket is at its widest point, 6mm is 420 7mm is 428 :)

Notes on replacing drive sprocket on Genie 2042 belt drive garage door opener.
The unit originally came with a cast metal sprocket disk with a plastic sleeve insert that formed the sprockets themselves. The plastic insert's sprockets shattered when I tried opening the garage door that had frozen shut with ice. Genie's service assistant was of no help, as she suggested that I remove the entire rail then call them back. Removal of the rail was totally unnecessary. I purchased an all metal sprocket designed for the 2042 from an on-line supplier. Neither the owner's manual nor on-line instructions were available to assist me. I followed these steps:

1.With the door open, loosen the tension on the belt by turning the bolt in the tension assembly located on the rail opposite side of the motor. Slide the belt off the pulley and let the belt hang.
2.The sprocket housing is located on top of the motor. Unscrew the two Phillips screws that hold the sprocket housing onto the motor assembly.
3.Using a screwdriver, force the cover up. The cover is on a hinge-like appendage that is riveted onto the rail frame. With the housing pried up, the belt and sprocket can be seen.
4.Pull the belt out of the housing to allow the old sprocket to be removed. Be careful to locate the black plastic bushing/spacer on top of the old sprocket and save it for the new sprocket.
5.Install the new sprocket and bushing/spacer into the motor shaft along with the belt.
6.Replace the two Phillips screws on the sprocket cover.
7.Place the belt back on the tension assembly and tighten to manufacturer's specifications.
8.If the motor won't run from the wall switch, the up/down limits need to be reset. The motor will move the garage door up and down using the control buttons on the bottom of the motor unit. Follow the manufacturer's instructions on setting the up/down limits, which include holding the "set" buttons for over 5 seconds once the garage door is in the desired up and down locations.

Thank you for contacting FixYa with your inquiry. I have been going
over some of the older help requests that have been archieved and
trying to provide solutions for those that didn't get answered. Hope
this information helps.

Take the bag asm. and handle off. Then remove the plastic strip covering the switch, remove the screw there, remove the 3 screws on the housing, turn it over and loosen the screw near the back, the housing should come off. Then remove the screws on the back of the fan casing. You shouild be able to get to the fan, hold the fan and turn the spindle to the right to take off. If it would turn off, then you may have to lock the armature so it can't turn to move it. Then re-asemble in reverse.
