Brand: Whirlpool Model Number: WTW5540SQ Main Symptom: oil leak What happens & when: wasn’t spinning much
Error Code (if any):
Parts or tests already tried: Replacing the clutch, both transmission seals, motor / transmission coupler.
My question is… While I have it apart, what other seals, parts, or maintenance should I reasonably do? The brake pads don’t look bad at all… but I wasn’t sure what is basic maintenance.
What about the tub seal, should I just automatically replace it?
The seal in the upper end of the basket drive tube? Should I replace it?
Do I oil or gease anything, tube, shafts, etc when I put it back together?
Unit is direct drive Whirlpool and is 20 years old.
Are you mainly trying to correct the oil leak, the slow spin, or both?
In most cases these two problems are actually related. Even a very small amount of transmission oil getting onto the clutch lining will cause the clutch to slip under load, resulting in a slow or weak spin.
Since you already have the machine apart, I would recommend replacing the entire clutch assembly (Whirlpool 285785 Washer Clutch Assembly | Genuine OEM Part ), not just inspecting it. Even if the clutch pads still look good, oil contamination isn’t always obvious. A quick check is to try rotating the clutch lining inside the clutch. If it moves with little resistance, the clutch is worn or oil-soaked and should be replaced. Given the age of the washer (around 20 years) and the work you’ve already done, replacing the complete clutch is inexpensive insurance.
Tub seal: I would only replace it if it has been leaking water or shows signs of wear. They generally don’t need to be replaced just because the washer is apart.
Upper basket drive tube seal: Likewise, if it’s dry and not showing signs of leaking or damage, I would leave it alone.
Brake pads: If they still have good thickness and aren’t oil contaminated, there’s no reason to replace them.
I would not apply any grease or oil to the transmission shaft, basket drive tube, or clutch components during reassembly. Any lubricant that migrates onto the clutch lining can cause slipping. Just make sure everything is clean and dry before reassembling.
Also, don’t forget to reinstall the slinger ring that sits on top of the clutch. Its job is to help keep any oil away from the clutch, and leaving it off can allow another oil contamination issue later.
If you’re replacing both transmission seals and the clutch, you’ll have addressed virtually every common cause of an oil leak and slow-spin condition on this direct-drive Whirlpool. If you have any questions during reassembly, feel free to reach back out and I’ll be happy to help.
