NC Ohio | Before season started I took apart variable speed sheaves a part on header drive on my S 670
Noticed some wear on the drive lugs inside so I replaced both halves on upper pulley new bearings and put new belt on
I smeared some grease inside and put it all together Pumped some grease in it and cycled header speed up and down a few times
I slowed head down all the way on hooked our bean head on combine and started running beans
I unhooked hyd coupler and greased it again after about 30 hours and cycled it again a few times no problems
We got rained out over weekend so hit all grease fittings and checked belts and such and figured all is well. I backed combine out of shop and figured I would cycle header drive and cyclinder drive again after greasing and header drive would not speed up
I checked front pulley and it would spread apart fine so tore upper pulley apart and found where the cog ran into groove had worn a deep groove into both upper pulls
My concern is how can they wear that much after less then 50 hours. With both pulleys being brand new from Deere New bearings and belt
I understand that on a grain platform that pulley never gets cycled but the one I took off was not as bad of shape as this new one
Also I am very anal about cycling it every time I grease it. Granted I don’t grease it every 10 hours like book says but am I the only one that doesn’t grease the upper pulley everyday and unhook header and cycle it
The original didn’t get greased every 10 hours either and it lasted 11 seasons. Combine is a 2013
Also I made sure cog was in the slot when installed. As you can see from pictures
Do you think it could be some bad steel on replacement. I kind hate to spend another thousand and buy both hubs again Only to get another 50 hours out of them
