Yes it is a B'stad.

Now that's what I call a puller.

[nicklouse]

Yep. I have 2 old SP ones from 20 plus years ago that have done me well but with needing to do a verto and not knowing if I had the right bolts and having seen this at the IMM it was a bit of a no brainier.

Thats a very pretty piece of kit there, looks well built...

I have flywheel puller envy now!

[MacGyver]

Woooooo! Me want!!! 😯

[nicklouse]

For comparison here it is beside one of my old ones. Common SP one.

Which has had the bolt speadso you can't wind it all the way into the plate and the end is kinda stuck on it.

What sort of bunce was that?

[MIGLIACARS]

nice

[tiger99]

Just curious. The force the flywheel puller can apply is limited by the three bolts and the strength of the threads in the flywheel. The bolts, if Allen head, will be at least grade 10.9 and possibly 12.9. The flywheel is not made of the same stuff as grade 10 or 12 nuts, so its threads will inevitably fail first. Has anyone had this happen, and how did you recover the situation? Drill and tap for larger bolts, or cut the flywheel off?

[nicklouse]

Helicoil.

I had a nice teng tools spanner set delivered yesterday but you've trumped that! Lovely bit of kit

I was thinking the same thing tiger99! Surely the performance is a lot to do with how " stuck on " the flywheel is and the condition of the bolts and the threads they are going into! I have the old school puller with the larger imperial thread bolt and I've found it to be brilliant! But yes in the case of a stripped thread surely drilling and tapping is the only option? Would a helicoil real be up to all that torque on the threads

[nicklouse]

But it has little to do with anything. The force will be the same what ever tool is used.

The fine thread means less force is needed by the operator.

Yes more force can be applied due to the finer thread.

Yes helicoils are strong enough.

[cian]

Yes force is the same with any tool but not every tool can deal with the force, those cheapo pullers are not up to the task I've had two sheared bolts with them, so far the older puller had performed great! The old saying " they don't make me like they used to " certainly applies, don't get me wrong that pulley is an absolute beut but il stick with the old faithful lol
