149 Differential cover torque specs
 

Hi all,

Need to button up the diff cover on the 149. What are the bolt torque specs? I checked both the service and owner manual and didn't see any specs. Don't want to over tighten and cause a leak. Star-pattern tightening like on a car tire for best results, right?

Secondary question: anyone got a good video or step by step write up with pictures on how to tear down the K321A engine and rebuild one? Never done it before and I like being able to follow along.

Thanks!

50 in-lbs? That doesn't seem very tight at all. That's like, 5 Nm and my torque wrench doesn't even go that low.

It's a 3/8" bolt which is normally 32 Ft Lbs. But I'd pay close heed to the Cub Experts. They know their stuff.

It is your tractor. You can tighten them to what ever you want.

I ain't saying I won't do it, I'm just surprised is all.

If that were an aluminum rear it would be 30 ft/lbs so I'm thinking going into CI I would do at least 30 but no more than 50 ft/lbs.

Tighten to specks,
if it starts leaking,
tighten more,
when that don't work,
take cover back off and hammer the inward puckers around the bolt holes at least level, maybe a bit outward then reinstall using either the gasket OR RTV, not both.:beerchug:
Or you can hammer the puckers out first, then once and be done
BTDT. multiple times :biggrin2:

I tightened to 50in-lb and filled her up.

No leaks after a test drive; runs amazingly smooth with new tires and new hydro fluid.
