I have a 2000 Murray rider mower model # 40507x8A. The motion drive belt came off the pulley drive ( sits on the transaxle). While i was putting the chewed up belt back on I noticed the pulley drive plate was wobbly. My question is how much play should be in the pulley drive plate? Could this be the cause of the belt coming off? I do plan to replace the worn out belt. Would it be worth replacing the key, woodruff and e-rings. Are there bearings in the drive pulley?
thanks for your help
