CS 100 Tight bolts on blades

[raafbeard]

Coming to turn blades for first time. Torx nuts are proper tight and in danger of major roundings.

 

Is there a recommended torx bit to use or technique for loosening these for the first time?

 

Without slating the product is it worth changing these to an allen bolt?

 

Additionally is overgreasing the cassette bearings really an issue?

 

Apart from that its a beautiful little compact machine, although there is a tendancy for shredding on whippy bits but this is true of all chippers.

 

Any help appreciated.

I had the same issue and it took two hours to eventually remove the bolts as they’d been untouched for a long time when I first bought it.
I’ve now gone to Allen bolts and problem solved as well as using a little copper grease when on the threads.
Not had an issue with the greasing as yet.

On my Jo Beau I use an impact driver; it saves the bolt corners.

Toro bolts are used for a reason!

A Torx head can... actually accept more torque than a hex head or Allen socket head as long as the proper torx bit is used, It's the same principle as a philips head screw as opposed to a slot head. The torx pattern has more bearing/contacting surface area to spread the torque force over.

Failure is usually due to incorrect size, worn tools or incorrect angle of use.

In relation to the torx bolts holding the blades on, a good quality impact driver (the type you hit with a hammer) with a socket style torx the correct size (IMPORTANT! Clean out torx head with small screw driver or pick) first tighten the torx bolt! One good blow of the hammer, then spray with penetrating fluid (WD40) now undo the torx bolt twith the impact drive 2-3 good hammer hits and they will normally be turning.

Once removed

Clean bolt threads with wire wheel or wire brush apply copper grease not loctite retighten
To torque setting.

As above, invest in an impact driver. I had to drill a couple of rounded torx bolts out of mine.

Please ensure you only torque these blade bolts to the recommended 28Nm.

If you can't remove them I've found the easiest method is to simply drill the heads of the bolts off using a sharp drill bit.

It's easier than you might think..
