Accidentally spun the motor backwards a bit

[Nodak]

Hey guys. While removing the clutch I wasn’t paying attention and spun the motor backwards. Not much maybe 45 degrees. I’ve heard that’s bad. What are the consequences of doing that? The motor is coming out anyway so what should I look for to make sure nothing got messed up. Thanks guys.

The timing chain can become slackened and the cams can jump time. If you’re pulling the motor anyway just verify the timing marks are still properly aligned and you should be good to go.

Thanks. Felt like it had good compression still after turning the correct way. I imagine it’s not a problem unless it is started and ran after something like that happens? Turning by hand is slow and gentle enough that it can’t really bend anything?

You shouldn’t hurt anything turning by hand, no, but you def want to double check the timing marks. If timing jumps a single tooth you shouldn’t break any hard parts but you’ll see funky running quality issues.

It's very rare, but possible.
