My maytag dryer was squeeking, I replaced both drum rollers and belt.still squeeks and now has a ticking sound. i'm thinking idler pulley wheel what else could it be?
Answer Jay, The idler pulley 6-3037050 is the only rolling component left, when it starts to fail it makes a high speed, high intense squealing noise. Make sure you clean the idler assembly shaft and place a thin coat of high speed turbine oil on the shaft and bearing of the new idler pulley. Also check and clean the drum glides on the front bulkhead where the drum rides on the glides, a little dab of silicone grease will help as well.
What kind of bearing is in the idler pulley? How does it work? Does it spin on the shaft or does the bearing stay fixed on the shaft and spin inside itself?
Answer Hello Matt,
The idler pulley actually hasn't got a bearing in the true sense of a bearing. It is more accurately described as a bushing. The bushing is made of a material that actually lubricates itself as it wears so it requires no lubrication. Never lubricate it with a wet lubricant as lint will stick to the lubricant and will be drawn into the bushing and wear it out quicker than if it were not lubricated at all. The only way to lubricate it is with a dry lubricant such as baby powder or corn starch. Graphite cannot be used because if it gets into the wash, it will stain laundry. The bushing spins on the idler shaft. It remains stationary inside the pulley.
Do I need to grease the Idler Wheel when replacing?
Answer Hello Kevin. No, the bearing on the idler wheel 6-3037050 is already prelubed. It does not need grease. Hope this helps.
My idler pulley is making a knocking noise. Would you advise replacing the arm also and are there any bearings or bushings? Thanks
Answer Hello Don. If the arm 6-3033630 is wore, it would be a good idea to replace it as well. The bearing for the idler pulley comes installed in the new wheel. Hope this helps.
