1982 XC 430. How hard should it be to spin my counter sprocket without chain when bike is in neutral? Feels like it was fairly easy a few rides back and now little harder to spin. Was lining the chain and noticed the wheel did free spin as much as before. Thought I over tightened the rear brake but not the case. Took chain off and wheel spun freely. Use my hand to rotate the sprocket and there is some resistance. Seems odd like something binding. Using ATF in tranny. Other than that the bike runs great. Is this normal or is something binding in tranny?

Hi everyone,
As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.
When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.
Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.
Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.
Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.
Thanks for your patience and support!
Neutral Countershaft sprocket spin

It should not be very hard to spin that sprocket in neutral. It is a constant mesh transmission, some of the gears on that shaft will spin on that shaft at a bushing and some will spin a gear on the other shaft that spins on the other shaft at a bushing. I would check the oil for bearing pieces/chips. That bearing at the sprocket is probably the most likely one to fail. Unlike the 87-88 there is a plate that comes off but without prying out the seal on the bearing it will be hard to see the balls or race.
The rod that two shifting forks in my experience has been found slightly bent a couple of times. Did you crash on the shifter side lately?

I am not sure how to really answer that. It is a single row ball bearing, normal no loading slot, I think 9 balls. If the case is hot enough the bearing will drop in and if the bearing is hot enough it will drop on the shaft. Otherwise some force is needed. It is supposed to be a sealed bearing with a seal on one side. There really is no seal of the sort commonly called a seal with three dimentions id od and thickness. Some people use a sealed bearing and don't take the inner seal off which I do not think is ideal. Bearings generally come either no seals, two rubber seals, or two metal shields, at least to my understanding. OEM can get more specific stuff.

the bearing is pressed into the cases, so the countershaft basically floats inside the bearings inner race with a tight "hand press fit"
i have seen a few swedes with transmissions hard to turn in neutral. every one of them had a few gears completely roached.
