Seized Front Sprocket.

Discussion in 'Technical Help' started by West Cork Paul, Aug 1, 2019.

  1. Put a flat bar on the end of the shaft instead of a bolt in the hole and put the puller screw onto that.

    As I said before, use a hydraulic puller. They have much more force than a std threaded one.

  2. Hydraulic pullers work well however if you have access to an angle grinder fit a thin cutoff disc. If too big in diameter then trim to smaller size using a bench grinder. Cut two quadrants one on each side close to central shaft but far enough away not to damage shaft. With the two quadrants removed use a dremel and cut towards the bottom of each spline on each side. This will cut the remaining sprocket into two halves which will fall off the spline. Use my dremel a lot but for something this thick always start with angle grinder first to aid rapid removal. Will be off in minutes.

  3. Seems a big faff using grinders...go to your hire shop and hire a hyd puller for a few quid.

  5. I'd sue the garage door makers. The mountings were obviously substandard.

  6. Well, I don't feel so silly now. It genuinely can happen to anyone.

    Thanks, Borgo!

  8. Novice mistake! The hole should have gone through the wall not the door :rolleyes:

    Worked a treat back in the day with my mates Honda, we tied it to the front of the car too not the back :thinkingface: but got a bit of recoil, your rope idea is better than a bungy, granted o_O

  9. Perhaps a VET - should've used the tractor..... :thinkingface:
     
  10. The problem there is you were using an Allegro by the looks of it. Should have used something a bit stronger/sturdier:)

  11. It was momentarily connected to a Jag, but perhaps not for long enough :thinkingface:

  12. Agree but works and if you have access to a grinder costs nothing with the exception of electricity.
     
  13. Can I just say something
    There is a groove in the shaft. The splines at the front do not line up with those behind it.
    So if you do get it moving you will need to line it up with the front part

  14. I'm sure you've got that wrong higgy, the groove is for the locking washer and the sprocket would never go on or come off if the splines didn't line up.

  15. Very useful, thanks:upyeah:
     
  16. Has it left yet ?
     
  17. there should be some room to tap it backwards towards the engine, as when i last changed a front sprocket on my 996 the sprocket retainer also brought forward the sprocket in alignment.
    if you can tap it back wards and then pull it forwards slightly you will be able to break the friction between the two.
    take care if you damage the output bearing, you will be splitting the motor to repair the subsequent results.
    if in doubt cut it off as discussed above, go slow and easy and it will go ok, a grinder and dremel will have it off in no time :)
