Been through 4 clock springs so far. For such a good loader and batteries its a real pain in the ass to have the weak impellor.
www.viewloaderparts.com states that the standard impellor setup can be used instead. Although the standard set up seems alot stiffer than the clockspring, one hopper load of paint has gone through ok. Trying it out with lots of paint tomorrow at training.
I've been searching for a Dynasty conversion kit in the uk but stores have told me they are like hens teeth and may start to be availble in the uk in 4-6weeks.
Hope thats of some help, but warrenties from the store are always the first port of call.
