RA axis tight section

[email protected] #59944 I'm in the process of cleaning/regreasing again, and this time noticed when reassembling that there is a definite stiff section when rotating the RA main spur gear by hand with the clutch moderately tightened (the worm is NOT installed).? I believe that the RA bar is not quite square to its upper plate, resulting in the two surfaces that are compressed together? not coming together uniformly.? This is a terrible explanation, so please see the picture in the link, where I have removed the clutch pad to visualize the gap (on the left, which is then on the right when rotating the RA axis by 180). Now I'm sure this has always been this way and I've just never noticed, so just wondering if there's anything not extremely invasive I can do about, or whether I should just move on and ignore? Thanks, Keith
tom #59945 May not be relevant to this issue, but I seem to remember in the earlier G11 models the shaft is secured to the plate assembly with an allen screw. I had to re-tighten it once when I found as bit of play. Tom toggle quoted message Show quoted text On 1/22/2018 12:10 PM, keithnakonechny@...

Michael Herman All Messages By This Member #59946 Definitely worth a call to Losmandy to discuss their view...their possible support options.? if it was a mfg defect they might repair it free (aside from shipping).?

Chip Louie All Messages By This Member #59947 Hi Keith, If these parts have not been obviously damaged or dropped this should be addressed by Losmandy. Call and talk to them and send the photo and they will have a plan of action to resolve this issue. This is one of the problems I have run into while helping people get their G11 clutches to hold. As you can see the gap will prevent the full clutch surface areas from mating which significantly reduces clutch holding power. Call Losmandy. Chip??
[email protected] #59948 Given that this is not a new mount (over 10 years old) do you think Scott will be receptive?? Worth a try I suppose. Thanks, Keith

Eric Chesak All Messages By This Member #59950 This looks suspiciously like the same problem I had with my GM8. This mount had this problem for quite a long time.? Nothing was damaged so it's possible it was like this as new.? The anodizing was worn off the DEC shaft (see the link in the post below).? Have you checked to see if the end-caps are pressed in straight. it only takes a couple thousandths to throw off the entire system. Mine had this issue.? It turned out to be pretty easy to fix. After the repair, mine is smooth as silk.? Take a look at the topic here for my situation: Also feel free to ask questions.? I have a solution that you can try, even if you don't want to measure anything.? All you need is a coupe blocks of wood and a hammer.? Problems with the bearing caps appears to be fairly common. Good luck. Eric
[email protected] #59951 Thanks Eric.? I'll check for bearing marks on the shaft.? I'm pretty certain the end cap is not on straight but will try to confirm this evening independent of mounting the shaft (i.e. the photo I included).? Will report back. Keith
[email protected] #59955 Just to follow up, I contacted Losmandy and they offered to re-machine at no charge (except shipping).? The links below are a few more photos for reference, compared against a high-precision machine square at my work's machine shop (part rotated between photos): Keith
photon_trap All Messages By This Member #59962 After reading this thread I ran out and checked the shaft squareness on my disassembled GM8 thinking that might be another "issue" contributing to very similar symptoms I am experiencing. Mine is in fact square but the thrust bearing surfaces are not parallel, (w/no gaping) resulting in the same effect. I am in contact with Losmandy - Sadly I see similar examples on here here quite often, it's frustrating that their idea of good enough is often just not.
