    This is an excellent how to but unfortunately a new bush bearing kit does not solve all problems on these dryers and many buy the bearing repair kits hoping they will work: The gas version is much sought after and probably still worth repairing? The poor plastic bearing bush design on all these dryers wears and the drum starts making creaking, cracking and clunking noises. A repair using a new bushing kit may be too late, because the aluminium spider retaining the bush can wear oval and over size causing the new bush to be a sloppy fit and rotate. In some cases, rivets holding the aluminium bush carrier can work loose and the drum will never run quiet and true. Symptoms of loose rivets are noises when the drum gets hot. The rivetted aluminium drum support is not available as a spare part. Some claim the drum itself can be cracked (or is it?). Unfortunately, and there are no longer any expensive new drums available.

    However, if the drum is still good, the bearing carrier assembly can be removed completely and modified to accept larger M6 HT cap bolts. The aluminium bush carrier can be reamed out to 22mm and a ptfe ‘top hat’ profile bush turned in a lathe and fitted. This should extend its life considerably. Increasing the size of the steel spigot to 12mm and machining the ptfe bush to fit is a further improvement.
