Hi folks,
I am having a recurring problem with the above machine. The bolt attaching the drive pulley wheel to the back of the drum keeps working loose. It is 'locked ' using a mild steel plate with its lugs bent over the flats of the bolt head. The plate is so soft it doesn't hold for long.
I have tried a lockthread type glue with only a marginal improvement. I can think of several potential cures but would appreciate your help/advice. Firstly, the thread on the bolt looks rather sad - does anyone possibly know the thread size of the bolt, and would a replacement be worth a try? Secondly, would it be worth making a new locking-plate from a stronger metal, or would this cause a potential problem? Thirdly, would it be worth using a stronger glue on the bolt thread?
My latest attempt is to use a split sprung washer. I will know in a a few washes whether it's successful. Apart from this problem the machine works well and I am reluctant to replace it for this relatively minor, but annoying, fault.
Thanks in advance, Alan D
