Probably going to get a lot of 'manual says grease' replies in this thread but I'll post anyway.... I'm replacing chain,did gold, sprockets, 42/15 so decided to clean eccentric hub at the same time and thank you to all that have made the job easier than it looks, biggest issue I thought would be the circlip but bought a set of circlip pliers 13" of ebay and was pop but after searching here for what grease should be applied (greaseB) to the hub I decided to call to a local specialist who is very well respected in the North East and he said 'NONE' the hub works on frictions and applying grease only acts as lubricant and also holds small particles of dirt and that's not what the eccentric hub needs, Give it a thorough clean and wipe with wd40 and replace, he's been doing them this way for 20years and wouldn't do it any other way and never had any failures or problems, I've followed his advise and now waiting on new sprockets to complete the job...which tbh isn't that hard and very therapeutic
Why ask the question if you're not interested in the answer? Are you waiting for someone to say the service manual calls for grease so you can argue against it?
I'll change the title as yes it looks like I'm asking the question when really I'm not, I've gone with advise I've been given, it will be interesting in a year or so time when I clean it again and can't get the hub out and then be thinking to myself....s*^t, should have greased it
“Grease” covers a wide range of product. I’ve always rebuilt them with anti seize to prevent corrosion issues. No issues over the years but the hubs stay easy to adjust and come out like butter at the next service. Everyone is going to have different ideas and many will work, but the newer stuff, particularly MTS and Diavel, seem to take on a lot of debris and water in the arm. For my mind, the two clamping surfaces need something to stop water ingress and corrosion. Factory fit dry and and I see more seized hubs in that state than after I’ve serviced and rebuilt with “grease”
I used to use this - https://www.ebay.co.uk/itm/Castrol-Molub-Alloy-Paste-White-T-100gm-Tube-/184295920857 on splines etc, on shaft drives on GS's . recommended or - this https://www.amazon.co.uk/Duralac-An...c+paste&qid=1597565518&sr=8-1&tag=googhydr-21 basically the same .....
I could always take it apart again and grease it before fitting sprockets I did actually call in to get the correct grease to apply as didn't know what grease B was and was quite surprised when he said DON'T In a very firm way. So do you use any anti seize or a specific one ?
I use alu slip. I have pots of the stuff around the shop as it’s my go to anti seize. I don’t tend to use copper based ones, can’t recall why tbh, but the aluminium based ones have done all that I’ve asked of them.
Galvanic action is why you wouldn't use a Copper-based product, which is why you don't have issues with your Aluminium-based one. Here are some interweb words... "...Aluminum will be very susceptible to galvanic corrosion in contact with copper, assuming that the two metals are also in contact with a common electrolyte (such as water with some ionic content.)..." ...that put it better than I could 'cos I just woke up
It’s called Alu Slip iirc. I’ve used a few just as a general workshop go to. The Alu slip works well, and is cheap as chips in half kilo tubs. Higher melting point than copper slip and less conspicuous when used on fasteners. I hate seeing screw heads covered in copper slip....almost as if to say “look we used some grease”, but that’s just me probably. The Alu slip is also great for assembling exhausts. Keeps the slip joints slippy and easy to demount when changing rear wheels etc.
A greased eccentric hub will never rotate when properly torqued. There's very little force being applied to it in this way
While we're here, with people talking about crud in their swingarms, my 939Hyper has an oval rubber swingarm plug at the front. Do the Multi swingarms have a gaping hole there?
No. The holes are plugged there also. There’s a hole inside the chain gallery where most of the crap gets in.
