Saw a wheel balancer just down the road for £25 on facebook market place so went and picked it up on the way to work.
Pretty dusty and grimy but apparently working. Its the spin by hand type, but has the computer to work out the weights.
Gave it a clean up and tested it on some wheels, but I was getting crazy results, weights to be added in 100's of grams etc.
Opened it up and gave it a good clean, blew all the dust out with an airline, and cleaned the cutter ring. It works a bit like an ABS sensor, with a force sensor a bit like you would get on a set of electronic scales. Cleaned all that out and tightened some loose connections.
Checked the run out of the wheel mountings with a DTI - all good.
So decided to spin a brand new Mercedes Sprinter rim to check the machine.
Trouble is brand new sprinter rims seem to come pre buckled, at least its not pre rusted like most of the mercedes parts that I unbox.
It spins up with 0 0 now though, before it was spinning at 10 10.
Tried the bent rim that was giving readings in 100's of grams earlier.
Gave me reading of 20 50 this time, I dont have any spare weights so used some scrap ones 25 40, spun it again and got 15 15.
So it seems to be working reasonably well, I will test it properly at home, but pretty pleased with my bargain!
