Is the Grease nipple something you've added in @AHPP? We have a H2 that doesn't have one, just a hole. Can't find any maintenance instructions other than what's on it

Is the hole threaded?

You’ll have to ask someone with a Hobbs!

 

edit: You did. The world doesn’t revolve around me.

Doesn't appear to be

"Thank you for your inquiry. We do not build the H-2 with a grease fitting. There is no need. There is nothing to grease. No bearings or bushing. Someone took it upon themselves to "improve" the H-2 by going to a fair amount of effort to add something that does absolutely no good. If you think about it, the spool is locked solid when it is doing what it does best: providing a means of taking wraps and controlling the descent of sections of tree. When the spool is moving it is in the process of taking out slack in the lowering line or raising a piece to clear an obstacle. The action of raising is slow and deliberate by design, therefore no heat is generated, nor appreciable wear on the spool. I hope this answers your question. Feel free to contact me anytime. Please acknowledge receipt of this email. Thank you.

If you think about it, 

Well I've thought about it Donald, and every single time someone uses that phrase in an explanation it pisses me off.

 

My thoughts, when you're cranking tension to raise a piece there is sliding friction between the drum and spindle. Not enough to cause excessive wear, or get hot, but the coefficient of friction will be lower with a bit of grease - so the effort on the handle for the same rope tension will be lower.

 

Not much effort really either, bit of drilling and a quid for a grease nipple.
