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.
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?
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.
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.
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..
Although the cuts extend down to the shaft at the front do they also cut through the shoulder at the rear?
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.
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.
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.
@Cream_Revenge would have got it off by now where's he been recently c'mon Creamy, cavalry charge needed
These are reassuringly expensive, but appear to have sold out at the moment: https://lostartpress.com/collections/tools/products/lump-hammer
