Maschio- How tight?

[kevindb880]

Will be putting new tines on our Maschio DM power Harrow shortly, I have always done them up bloody tight and a bit more ( never had one come loose)
As I now have a torque wrench does anyone know the correct torque before I ask a dealer?

 

[nick...]

Bloody tight and a bit more then check the torque wrench figure.

It’s the torque figure that I want!

Do a google on torque setting fir the bolt size. If your still not happy give it a tug more. If the ones that are on there haven’t ever snapped of come loose Mark across one and crack it’s loose the use torque wrench to re tighten to the marked position by adding 5ftlb at a time. Then you’ll have your torque. Or just stick with three grunts and a fart.

FT and a bit more, as long as you can get them undone and don't strip the threads. Mind you there is always the gas axe to get them undone

Would FT be with or without lube?

 

[snarling bee]

Definitely without. Or just use a bit of WD40 which will evaporate

I’d still use thread lock with self locking nuts Then cut them off with a torch next time. Better than finding an ovaled out hole and a loose tine.

This is as good as it gets from the operator's manual for a DM harrow.

I'd expect the bolts to be M16X1.5 so torque to 301 or 361Nm.

 

[kevindb880]

Anyone know where you can buy grunts and farts?
Spoke to a very helpful man at Maschio today and it is 361Nm, my torque wrench goes upto 150 so it will be a long length of pipe as usual!

Put them in a bucket of water overnight ,
was told this , no idea if it works ,so its strts them rusting ,
never tried it ,

 

[agrimax]

Think I'd be putting them in with copper grease...they''ll have to come out again sometime.

TT=(L+E)/L
where TT= true torque
L = length of torque wrench
E = Extension
so to get a torque of (361Nm) or 266ftLbs you need an extension as your torque wrench will only read 150max.
If your torque wrench is 600mm long with an extension of 600mm this will double the torque.
So a setting to give you an output of 266ftlb is 266/2= 133ftlbs

i would have thought the spring will still trip the mechanism at the same torque? or one way to knacker an expensive tool. am i being thick( as usual )?

Torque wrenches are a bit old fashioned the modern way is to count how many Ugga duggas you hear with the big impact gun

 

[agrimax]

About 10 Ugga duggas with the impact gun and then 6 grunts and 3 farts with the knuckle bar just to be sure...
