Using our 50 years in manufacturing experience we have made the perfect gears. We have manufactured a set of gears from stronger materials that should have been used originally. Brass on plastic is a perfect combination for gear wear, it reduces wear significantly compared to plastic on plastic like the original, whilst more expensive, it is a far better solution to your M engine! We have also manufactured a replacement shaft and pre fitted the gears meaning less work for the mechanic!
