This is the part we are waiting on now. Not your fault Torvy, you and others gave the best personnel experience information you had. I am concerned that all of us are driving around with thin walled hubs like this one, but even if they fail I don't think they will cause the loss of the wheel like the clips would...fwiw, this tractor DID have the new clips vs the old "dog eared" ones so TYM has already corrected that problem in newer builds.
To your point, I guess it is good they don't have the part in stock because maybe the failure rate is not high...but 6-7 months is still too long for any part IMHO...my berco dealer had to wait that long for the foward/reverse switch for his big 5 series TYM last year.
