What's happened here ?

No prizes for guessing :

 

1. What I've just done

 

2. To what machine

 

3. To what make of machine

 

 

Come on TW, it's about time you used something different

[Kev Stephenson]

Tw150 blade bolt extraction by welding enough bolts on to spanner it off

[geoff]

Yep,those star heads are a right inadequate pain,you did well to get that out Dean,feel for you!

[roseyweb]

I agree had to have mine welded out once at great expense.

 

I've just ordered some new bolts for mine and change them every 5 blade changes

 

and also the torx bit, where can you buy them with out having to buy the whole torx set

[likeitorlumpit]

C'mon lads

a bit of mechanics subtlety needed on these

If you put torx into extension on a long arm wrench

Jamb the flywheel with a bit of wood

Then

and this is the clever bit

as you exert pressure on the wrench

keep lightly tapping with a hammer( well get someone else to do this)

works a treat

Also helps if you clean out the torx with a sharp object first.

Also put copper grease on threads of torx bolt before fitting after putting in new blades

There you are

My simple( well maybe not so simple) solution to a TW problem

we've used the same torx bits now for about 20 blade changes

It tends to happen to some people more than others

Also put copper grease on threads of torx bolt before fitting

don’t forget the underside of the head of the cap screw

All the above plus tens of other techniques...

 

 

Top and bottom of it is you should not have to tap on the back of anything.

 

TW need to use a deeper headed bolt, not a shallow one. I even flatten the small dome on the end of the torx bit so the spline sits deeper

[likeitorlumpit]

I know!!

 

Mechanics is frustrating specially when you've had a hard day/ in a rush/ it's about to rain.

I agree it would be great if TW came up with a simpler system but there you are

My solution works every time. Give it a go.

Still having said that, I'd love TW to get back to us on this. With a reason/upgrade

Thats about the top & bottom of it!

[Dean Lofthouse]

I've made a special tool where the torx bit fits in the bolt head, then you rotate the flywheel till the bit goes behind the case, the bit is the exact length needed to touch the back of the case and not let the bit ride out of the slot.

 

But there is very little helps when someone else has had a go and rounded them slightly.

 

My point here is, I have never ever, even slightly rounded the hex key bolts on my Bandit, I know you are supposed to change them, but mine are the original bolts and I have had my blades off maybe 40 times.

 

TW used such shallow heads there is a huge risk of a novice damaging them, whereas on my bandit, the hex bit would snap off before it rounded
