Fusible drive flanges

[thinfourth2]

I have a hybrid trialer and a lathe in my garage.

Now so far i have had one diff fail on the hybrid, which meant thats the day over on the trialing front and a few hours and expenses to replace.

It seems diff is the weak point on the landrover drive train along with the CVs.

What i was thinking is would it be practical to get some drive flanges which cost about a tenner and machine out 25% of the length of the splines to make them the weak point in the drivetrain.

That way the first thing lible to pop is the drive flange which means should one fail you are five bolts to swap it out between courses and you are up and running before the next course.

Also would machining out 25% of the flange make it the weakest part of the drive train?

Is anyone able to calculate this or would it be a case of trial and error.

Or shall i just buy some shiny knobs

I'm fairly sure what you're planning is already in place from the usual reputable retailers. It might be worth a quick Google rather than spending time reinventing stuff.



(Knobs are good btw)

indeed - might of been ashcroft or similar.
Basicly a drive flange with a clutch in it - it would slip when overloaded.
