Good call, I was assuming that since the spec sheet had a Sugino cranck set, this was that! I couldnt find it on VeloBase, but I didnt try very hard. I remember selling bikes with Japanese cranks back in the day, but any really high quality ones were ususally Campagnolo, and to my eye all Japanese ones were either cheap swaged units, or Campy copies. I didnt give it much thought.

I have plenty of Sachs-Aris 8-speed freewheel bodies and sprockets. However, make certain you save the current freewheel for the sprocket spacers.

Sachs freewheels from this era often suffer from grease contamination which degrades into a sticky peanut butter mess. If your freewheel feels stiff, it has this condition. Also, this model used red plastic bearing cages which doubled as seals. This prevents the "dribble and flush" shortcut of service. You can't really get any oil or solvent in between the halves of the body.

As some will point out, there is a small hole in the side of the outer body which is accessible when the sprockets are removed. Again, you can attempt the "dribble and flush" shortcut through this hole, but it will be challenging, because this is what the interior of a Sachs-Aris freewheel often looks like.

The contaminated grease is difficult to clean off even when the freewheel is disassembled. Notice the red plastic bearing cages/seals. They do an excellent job of keeping contaminates out of the internals.

Notice how the grease is on the pawls. Sachs used the hole in the side of the outer body to flood the interior with grease. Grease shouldn't be on freewheel pawls.

Otherwise, these are great freewheels and IMO one of the best choices of the early 1990s. A complete cleaning, new synthetic grease, and few drops of machine oil on the pawl pivots, and you have a fantastic freewheel.

Yeah, getting old sometimes sucks.

But it sure beats the alternative.

PB, do you apply grease to anything other than the bearings and bearing races?

Mostly yes.

The exception is the old Regina, Atom, and a few other European freewheels. In those cases the pawls are shaped like flags on short poles. The pole fits in a hole in the inner body. The fit is so sloppy the pawls won't stay and fall out. I place grease in the hole to help it stay in place during reassembly.

I wish someone of your expertise had a video on YouTube overhauling a freewheel. Put the current video hacks to shame.

If I were to do a video, I'd need to hire cudak888 to be the producer.
The videos where the person picks up and places one ball bearing at a time with tweezers are hilarious!! It's a freewheel service not a surgical procedure!

I can place anywhere from three to eight bearings at once, just by letting the thin film of grease on my finger, "stick" the balls for the transfer from the paper towel to the race.

The other laughable is the copious amounts of grease used.

Wow, how did I miss this one? That's a beauty.

You need to hunt down the right Suntour parts and make 'er whole again!

Looks bigger than a 56cm to me though.
