Torque on forst chipper blades

[dan494]

Why is it then that some chippers have a stupidly high torque and others are basically hand tight? Surely all chippers flywheels have a similar rpm.

 

 

On the timberwolf it had much smaller blades with smaller bolts and 5 in both blades, on the Jensen it's just 2 bolts per blade and they're much bigger. Plus with the silly timberwolf system they're torx bolts so very easy to round off if over tighten. So guess it's that!

I see make sense I suppose. Want do do things by the book so going to ute the bullet and get the wrench

Ive just bought a torque wrench off eBay that goes up to 350 nm for £60.I've not opened it yet but it should be alright I guess.

 

 

Let me know how it is when you do use it, may go down the eBay route. Thanks

right to avoid opening another thread, I just needed some more information on the first st6 I have got. I brought it and have a user manual but not an engine manual. Just wondered if anyone knows what engine oil I need for it? Also if anyone has any ideas on what hydraulic fluid I should be using, there doesn't seem to be anything on that in the manual.

The machine is fine I just want to get these bits there just incase I need them. Also I noticed on the torque settings some go the bolts go up to 1050Nm but I'm guessing that is likely to be things that I wouldn't be going near anyway.

Thanks people
