Maytag Bravos dryer model MGD8200VQ0
« on: August 12, 2021, 03:35:50 PM »

This dryer was given to for possible repair by a friend. It had a pretty bad noise when I plugged it in and started the unit to rotate the drum.. The unit was dis mantled to see where the noise was coming from.   The blower was the source of the problem. This unit has a blower that lays flat on the bottom of the dryer housing and is operated with a separate belt from the motor, I removed it and found the wheel inside the housing has  2 bearings on the shaft one of which was worn a lot . So far I am unable to find a p/n for the blower or for these bearings.  They are 1.25" OD X .50" bore  X .375" thick and sealed both sides. I have checked with Grainger, Motion Industries, and another source for these bearings but no one has this size and type. Can anyone help me to source these bearings ?

Bearing number should be on the seal face or rim of bearing, recheck measurement with digital Vernier, may be a metric bearing with imperial ID for shaft, or (if you haven't pulled it) a flanged bearing, with additional 1/8 flange.

The bearings have been removed and they are not flanged bearings. Unfortunately they are Chinese bearings and the info on the face is in Chinese. I have double checked the dimensions and they are as stated---1.25" OD X .50" bore X .375" thickness with shields both size .Grainger has one that is close but the OD is not the same since it is 1.125" not 1.25 ". I am still looking !

If it's a plastic housing you may me able to squeeze in a metric/imperial bearing as I mentioned in my first post? 6201-12.7 10 thou bigger OD. Heat the housing up with a heat gun carefully to install! Thicker by ~18 thou too......

The housing already is built with a steel sleeve so I cant put in a larger diameter bearing.

Special bearings are made for OEM applications and done in a production run for the customer, they aren't available for general sale. So once the customer no longer carries the stock, that is the end of it.
If you don't find a bearing and you want to make a fix, easiest way is without having to machine up a shaft etc. If you buy a 1.125 bearing, you can buy a bush/sleeve and slip it over the bearing, i.e., chop a piece off. Depending on bearing containment, use some loctite or your favourite locking compound , or superglue etc!

Thanks for the info. I will persue this bushing as a last resort.

This Maytag Bravos dryer   design appears to have a significant noise problem as the blower bearings  start to wear.  The blower lies flat  as compared to other dryer blowers . I have worked on a ton of dryers and this one appears to be a poor life situation as regards the bearings  .Has anyone experienced  this poor life with the resultant noise ? Is there any alternative  since the blower parts are apparently no longer available ? Comments ?

A bearing of the size needed for this blower application was not readily available but one of approximate size was found at an ACE hardware location nearby. It was very slightly larger in the bore size and   very slightly smaller in the OD. A shim arrangement using very thin steel  material  was used to take up the gap in both locations and the bearing was carefully installed. Testing showed it operated properly with a significant reduction in noise.. It still operated with some noise but much improved. As mentioned before IMO this is a poor design as compared to the other horizontal  blowers used in the  Maytag or Speed Queen dryers.

Glad you sorted it. I hope it lasts for years. If I correctly understand the arrangement of shaft and bearing, I offer the following to you to consider for future repairs.  You would have been far better using a bearing and outer bush. Reason, you have a radial load on this shaft and bearing from the belt. Every single rotation applies the load on the shaft at every different degree of that circle, continually changing. Shim material in this situation can compress or wear and migrate. Had you used a bearing with the correct diameter inner, the shaft would have been solidly located in the inner bearing. The outer of the bearing in the bush has load in one constant direction, and a bush is a formed tube that can not dislodge or migrate. YMMV.

Thanks for the info. I would prefer to have used the proper sized bearing but none were available at least that I could find. If the bearings fail again  I will probably  put in a bushing as you suggest.
