Donny, I don't know. The CK30 manual error is just a fluke...
a simple typo. It Happens to all of us. The other figures are likely ok.

The 9-0 transposing just kind of hit me. Victor mentioned it a
couple of times, but it didn't sink in.

This begs the question of whether folks that properly retorqued the wheels to the incorrectly specified 290.7 lb ft
have caused serious damage.

I can only give a guess because I do not know the fastener
steel properties.

IF the studs/nuts are grade 8 or better and IF they were
retightened to 290.7 not more than a time or two you are probably ok. It just ends up being an unintended TTY fastener.
Do it four or five times with perhaps a little grease on the washer and you will have a 2WD tractor with a really good built in trenching attachment!

Tractorlegend's discovery of loose 30 lb ft fasteners is far more likely to cause rapid failure. It's good he found that
and told us about it.

Still the overtorque is not a good thing. This needs to be corrected immediately. It's a safety thing.

When I got my tractor all I did was hit all the lug nuts with a 1/2 air gun. Have not checked them since. I really should next time I go out.

I got my CK30HST last week. I went over every bright external bolt I could find with a 1/2" air wrench set to medium with a 4 hp compressor. I would estimate 90 ft lbs. at most.

A lot of the bolts did tighten half a turn or so, especially the big frame-to engine bolts.

My wrench setup couldn't move the lug bolts to tighten them, I didn't try loosening.
