Maytag Transmission O-Ring, where is it? |

I'm rebuilding a very grumpy Maytag A702 for Classiccaprice and have hit a snag.
We've got the washer apart. The top of the transmission is off and all the transmission's guts have been removed. I know the O-Ring in the bottom of the transmission failed and dumped oil on the floor. Whee the heck is this O-Ring? I assume it's in the input shaft tube in the lower part of the transmission case, but how far from either end is it? I've pulled out the input shaft and cannot see the ring. Dave | ||

O-ring is below the upper brass bushing. CLICK HERE TO GO TO DigAPony's LINK | ||

It's difficult to find if you're not familiar with its position. Even with a very small LED light shined at the perfect angle, it's still a PITA to locate. Here's a pic of where it's at. It's about an inch below the top of the tube. You'll need a pick set (a pick with a 45 degree angle works best) to get it out. I've done so many in the past I can extract them in a couple of seconds but that's experience talking. The first one took me FOREVER.

I think I've found something. | ||

The Ring.
In the thread linked above, there are specs for the O-ring. Since Ace Hardware was closed today, I had to go to Lowe's, where they hadn't heard of an O-Ring. I found some in the plumbing department, but they are all sized in fractions of an inch, not millimeters. They are also numbered (#35, for example).
Might any of these work? Dave | ||

Thanks
I'm using Brian's guide as my primary instructions and it's going pretty well. It's a team effort of me, Classiccaprice, and Elginkid, with some help from Combo52 via phone. Today, we'll try to get some O-Rings we know are the right size.
I do have a lingering question, however. Since so much oil leaked out the bottom of the transmission, how do I clean out the lower part of the transmission (specifically, the input shaft tube). Once it's cleaned out, how do I lubricate the lower bearing or bushing at the bottom of the input shaft tube? Dave | ||

Dave,
I used kerosene to rinse off all the transmission, including the shaft tube. You can put the transmission housing in a large plastic container and pour the kerosene through the tube by dipping it up with a can and rinsing until it and the other parts are clean. As far as lubrication, I put a little transmission oil on the o-ring to help it slide down to the groove below the bushing. You can put a small amount down the drive tube with your little finger or small brush that doesn't shed, if that helps you. Just keep it clean. Lube the drive shaft and thread it down the tube as described. The oil will work it's way down to the bushing and stop at the o-ring, if all goes well. It's the gear case cover bushing that gets starved for oil as the machine ages and the oil gets thick. Hope it works for you. Brian | ||

Doug,
One could put some power unit grease on the lower bushing if he wanted to or felt it might help facilitate installing the o-ring. Coating the drive shaft before inserting it in the drive tube will supply plenty of grease as the drive shaft is pushed down. Anyway, gravity with along with the oil channel groove on top of the drive shaft should keep the lower bushing lubed. The spline could be greased where it engages the brake. I would use a heavier grease than power unit grease though. Something a bit more sticky, like center seal grease. Something that won't sling. I don't think any grease has to be used here at all, as the splines just fit together for breaking and to stop tub indexing. I suppose a small amount could be used on the splines to facilitate assembly or to help stop knocking during agitating if the splines don't fit together tightly. As I recall, I just dropped the transmission down in the break w/o grease. My take on it. Brian | ||

Okay, no heavy grease on the bronze gear housing bearings. I mentioned applying some grease on the splines because the A512 I disassembled recently had grease on that area, it couldn't have been from a trans oil leak, the lower oil seal was fine. | ||

We'll see from here.
We got the O-Ring seated in the groove, but I think the interior dimension might be a tad too small. I coated the input shaft with oil and installed it. In the process, I very slowly and carefully spun the shaft as I inserted it up to the O-Ring. Then I continued to turn as I applied pressure. It took a fair bit of force, but the shaft suddenly popped past the seal and down the tube. It was so sudden that I took a tumble across the room as I had lost my balance. I fear that the O-Ring may have been dislodged.
I put the gears back in the transmission and put in some fresh oil. I placed some fresh paper towels under the transmission to catch any drips. Right now, my plan is to check the paper towels and oil level tomorrow afternoon and hope that there oil level is the same and that there are only a few drops on the paper towels from the brake (the lower half of the transmission is in the machine). Thus far, it's been almost 2 hours, and no change in oil level and no drips. Have I lost my mind? Dave | ||

Next Step.
Tonight, I'm going to use a Dremel to cut off the old agitator spline so I can reinstall the top of the transmission after filling it the rest of the way with oil. As of this morning, there was no change in oil level (a partial fill from last night). I'll then put the drive pulley and stop lug back on, bypass the pressure switch, and let it agitate and spin for some time to see if I get any oil leakage. It would be easier for me to fix an oil leak now rather than once the machine is completely reassembled.
