Seized Front Sprocket.

  1. You'd think that a tap with a hammer would get that off by now :eek:

  2. :thinkingface: Will try and take your word for it, but I’m talking about the F.O.big long screwdrivers, I’m pretty sure if I did this one or other of the two would result.
     
  3. Perhaps the sprocket and engine are a single part.

    Have you checked the parts list? Maybe you need to replace the engine when you change the front sprocket?

  4. Can you get a mirror behind the sprocket? Previous owner had several bad experiences with sprocket coming loose so welded to output shaft before assembly. :upyeah:

  5. Seen it done but always two tiny welds at the front, never the rear.

    I'm still amazed a screwdriver between the two halves won't split it wide open.

  6. The hydraulic puller exerts tons of pressure.
    As the force is exerted, it is contained within the assembly and doesn't load the bearings etc. It will pull the sprocket off.

    The centre of the puller stays still and doesn't rotate. The hydraulic screw puts a force into the ram and that's what pulls the sprocket off. It will not drill itself into the shaft.

    I do use this stuff most days..

  7. Although the cuts extend down to the shaft at the front do they also cut through the shoulder at the rear?

  8. I did mention that..
     
  9. Yes, but are the cuts all the way through to the back?
     
  10. He thinks so - hard to prove conclusively.

    Made final cut with hacksaw blade so by 'feel I guess
     
  11. Yes, Andy said that earlier Derek, and I believe Paul has used a hacksaw for the final part so certainly must go all the way through.

    You beat me to it Harry.

  12. I think he's waiting until someone starts up a crowdfunder for him and then - £1000 later - "Magic happened, the sprocket is off!".

    You'll see.

  13. I think the sprocket came off two days ago and he’s just having some fun.

  15. Depends on the hacksaw. If the cutting edge of the blade doesn’t extend beyond the frame (Like my junior), the frame will hit the shaft before the blade gets there.
     
  16. Think he just used a blade, you cant get frame in :thinkingface:
