What have people found to be the number one causes of broken wheel studs on drive wheels? Just come across some on a sixteen tonne forklift with duals. Thinking tyre pressures run to low? Operators going forwards to reverse to quick or braking to heavy? Fairly new machine under one thousand hours so not thinking metal fatigue is an issue

Can you post some photos of the setup so we can see how the wheels mount. Forklifts have multiple ways of mounting so it's best to see what we're looking at before offering opinions. Also some photos of the broken studs wouldn't go amiss.

Question. Are the holes in the wheel rims wallowed out (i.e. oversize or ovalized) on the wheels where studs have failed..?

Will hopefully get some pictures, a subcontractor is carrying out the work onsite. Just got a report in of two broken studs on the drive Axel. So was more just a general. 'fishing' post., if they are oval that may also indicate loose wheel nuts over a period of time. For a forklift it's getting a good workout, running twenty hours a day, every lift around twelve to fourteen tonnes.

The duty cycle or tonnage being lifted should have no bearing on this. The drive axle ought to be sufficiently robust (at least if the F/L came from one of the major manufacturers) to stand whatever operations can throw at it provided that the basics of wheel installation are being done correctly. Are they having a lot of punctures maybe ..?

The two usual problems are incorrect torque procedure and corrosion. What is the size of the tires and are they duals or singles?
