Thanks for the suggestion. It's pretty tight where I'm working. If it comes to it, I'll have to see if I can find a right angle impact wrench.
Either that, or remove the entire roller assembly from the machine so I can get at it.
Good luck in your endevours - and you better post the results! In post 63 it had “somebody’s” results that the ATF/Acetone mix was best. Liquid Wrench was about tied for second with Kroils. If it was me, I’d probably try the liquid wrench (plus I have it on the shelf!)
Tapping/hitting, sokaing, etc. all sound good. I’m no mechanic - but I wonder if a hairdryer on high would be hot enough to loosen things just a little bit, even if to allow the oil to get in farther? And I can’t imagine that would be hot enough to damage the neoprene.
Anyway - good luck! Nothing better than figuring something out and fixing it yourself!
