That looks to be correct. I tried to install the 189c (17mm, THICK) on my '69 and they were a chore. A friend and I put the 189 (10mm, regular) seals on his '68 and they went in much easier. Both kept the output shafts dry.

Chloe's sand rail seals never leaked in the 40,000 miles or so since the procedure. My rebuilt Rancho transaxle seals started drooling within a couple of thousand miles. Oy.

BobD is perfectly fine at 110,000 miles with 38 year-old factory seals, and this baby, Naranja, at 46,000 miles is likewise perfectly dry with 39 year-old seals.

My plastic lockplates are brittle and pieces are starting to break off. The seal doesn't seem to be leaking though. What will eventually happen when the plastic lockplates totally disintegrate? My bus came from Yuma, AZ and most of the plastic on it is crumbly from the desert heat.

My best guess is: nothing will happen. But there's always the option to replace before failure:

OK, I got the sealing caps for the flanges from Bughaus.com and replaced the plastic lockplates. Mine had thin washers under the circlips that held the flanges. Colin's trick of prying off the flanges with two screwdrivers using the lockplate screws as fulcrums worked great. They wouldn't budge if you pried one side at a time but if you pried both sides at once they came right off. When putting the circlips back on the ends seated right in but I had to tap lightly around the circumference with a screwdriver to get the rest of them to seat in properly. My seals weren't leaking so I didn't go any deeper than replacing the lockplates. There wasn't much left of the old ones.

You gotta stop driving past all that ozone out there in the pastoral splendor.
"What ozone?" you ask.
I have no idea, because I have never seen brittle plastic up at the transaxle side covers.

The brittle plastic is a result of it's previous life in Yuma, AZ. :angryfire: All of it's plastic is brittle. I've been gradually replacing all of it.

Does anyone know which WAY the spring washer that goes between the circlip and drive flange goes? In other words, is it positioned so the inner raised edge faces outboard? Or flipped so the OUTER raised edge faces outboard? Hope that makes sense ;o)

Rule Of Thumb

The Outer Raised Edge of a Dished Washer Needs To Contact The Larger Surface, i.e. The Flange.
The Inner Raised Edge Therefore Is On The Other Side Of The Washer and Contacts The Smaller Surface,
i.e. The Circlip.

Wow. That was formal.
