MAH7500AWW Bearing and Tub Seal – How To Replace them and save money

If you own a MAH7500 and it sounds like a jet plane then it is time to focus on your bearings and tub seal. If you bother a Maytag service technician they will want at least $950 to repair your Neptune or even suggest that you junk machine. You don’t really want to scrap machine because you can save money by replacing your Neptune bearings and tub seal and be washing clothes again. The reason they quote so much is because they will want to replace the large outer tub which runs over $500 alone!

The 12002022 seal kit contains two seals. The earlier lip seal and the revised lip seal. If you have the earlier lip seal (with plastic white spacer clip) you will need to replace it with the new earlier lip seal in the kit. If you would like to use the revised lip seal you will have to purchase a new spinner support because its’ shaft is machined different. Here is a video I created for the 12002022 seal kit breakdown.

It should take about 1 – 5 hours depending on how much cleaning you need to do while you’re in there and no special tools are required. You could save time by renting the Tony Tool which pulls the rear bearing out first. You then knock the front bearing out and then after some clean up you use the Tony Tool to install the new bearings and spacer. The tool kit rental includes an extra bearing spacer just in case you need it.

Depending on how long your machine has sounded like a jet plane you may need to heat up the aluminum hub when extracting the inner or front bearing. The aluminum has a higher expansion coefficient than the steel bearing does so the bearing housing should expand more than the bearing does thus loosening it up. Just don’t over heat it since some of the heat guns can really get hot.

Another tip is to stabilize the outer tub by laying the Neptune on its front and placing 2x4’s, old towels, newspaper stack under tub to help keep it from bouncing around when you attempt to knock out the front bearing. Now would also be a good time to spray penetrating oil on the inner bearing since it is closer to horizontal. You can allow the oil to soak in overnight. You will also want to place plywood or equivalent under tub to catch the bearing when it is ejected out.

The good news is that you don’t have the faulty brown tipped wax motor in your door latch. Only the timer knob based Neptune’s have the wax motor which would fail and damage the Q6 triac and R11 and the upper control board. The digital Neptune models all use a solenoid to lock the door. See Neptune Help Song for a video that explains what happens when the original brown tipped wax motor fails. 

I hope this was helpful to you and you save money by replacing your bearings and tub seal.
