    Sitting Duck got a reaction from Spacemonkey in Pinion to Bevel Shimming   
    Shims UNDER the bevel are not too fussy either
    it is the one place you don't have to shim to perfection
    as the pinion once installed is never going to allow the bevel to move
    Not saying don't bother shimming under bevel...
    Just that you won't need to shim it to fine tolerance like other instances to hold in position
     
    Take up some of slack under bevel - but don't fret over say fine 0.1mm tolerance say like other instances
    Try not to use larger diameter shims under bevel, if you pack a considerable bit with larger diameter shims
    it can impede/rub slightly with teeth on spur meshing to bevel I've found
    So I tend to/try to use smaller diameter shims under bevel & on top of sector
    (smaller diameter shims on top of sector is to reduce possible catching/snagging of tappet fin on sector shim)
     
    Rough ball-park figure...
     
    Bevel gear: 0.1mm to 0.2mm, maybe 0.25mm on TOP OF BEVEL
    (take up some of slack underneath)
     
    Spur gear: 0.1mm to 0.2mm UNDERNEATH SPUR
    (whatever is required on top)
     
    Sector gear - roughly 50/50 centered, check for rubbing against COL if too low
    & sector cam rubbing on box if shimmed too high (or thick chunky delay clip installed)
    (often a ball-park is whatever the spur has underneath - then add 0.1mm
    or 0.2mm under spur, then 0.3mm (ish) under sector, then whatever req on top)
     
    When spinning gears, also lay box on its side to listen for more friction/rubbing from gears or against box
    (you'd be surprised how sweet it sounds upright, but a tin of wasps on its side, so investigate if you got OCD)
     
    Once you got the gears "roughly spaced" or as you got the sector/spur "stacked up" nicely
    Turn box over so the selector plate side is facing upwards....
    lift sector gear up, checking for play - BUT look closely at spur axle...
    If when checking the sector play, the spur's axle lifts too...
    then they are stacked a little too close together and/or too much slack on those gears
    (if left unchecked - it can produce those "swirl marks" on spur gear)
     
    Another check & easier to see on a v3, once finished - have a look at how much of bevel's teeth
    actually mesh with spur's teeth through motor entry point...
    You want to aim for as much of the bevel/spur's teeth meshing as possible
    BUT you will never get it meshing as closely as say the sector-spur - you can get these close without touching
    but often the bevel-spur will not mesh anything quite as close...
     
    If there is very little meshing at bevel-spur, then try to shim the spur and sector higher
    by swapping some shims from top to underneath - keeping the gears together without becoming too tight
    (as said say shim the spur (0.3 or something now and also the sector increase underneath & less on top)
     
    Reason for this checking the bevel's teeth mesh with spur more...
    Moment you get any strain/lockup, the light meshing contact between the bevel-spur
    will result in those 10 teeth flying off as little may have made contact with spur
     
    You can view this as a weak point - at bevel to spur shim/meshing if you wish
    but it stands to reason, if little of the bevel's 10 teeth is making solid contact with spur's teeth
    only the tips of 10 teeth mesh with spur - then under load,
    the bevel's 10 teeth will tear themselves out at slightest sign of stress
     
    BUT - as said, you just won't get enormous near full contact across the width of the teeth like spur/sector
    Just check for hardly any contact width & adjust/lift up if possible, the spacing of spur/sector
     
    Some bevel's have chunkier and wider 10 teeth cut to spur, meaning better contact than others
    It is the instances where hardly any of the bevel's 10 teeth contact the spur
    (here is where a bevel may encounter "tooth decay" at some point under stress)
     
    Everybody's shimming technique varies & every box is different
    (heck some gear sets are smooth as silk in one box & rough in another box)
     
    But I check for sector lifting spur (selector plate side up)
    how much actual contact bevel to spur, if poor, look to lifting/shifting spur/sector shimming if required
    (as said it will never be extremely close, but look to ensure decent contact without throwing out stuff much)
    Spinning the gears upright AND on on both sides to listen for rubbing/contact of gears/gearbox case etc... 
     
    TL-DR
    check for gears being too close together (sector/spur example)
    check for decent contact between bevel/spur, or as much as feasible to reduce tooth decay
    spin gears upright and on sides (both sides) for any excess rub/friction if you have OCD  like moi
     
    or fuck it - just slap them in like the 5yr did at the factory sweat shop
    (and just say Homer Simpson style - it was like that when I got here/bought it)
     
    PS for the record - I know absolutely FUCK ALL tbh...
    my latest was a v3, shimming was the bollox - really smooth
    dropped motor, that was I thought meshing nicely at height/angle - even angle of cut of gears 90 degrees
     
    FUCKING PILE OF SHIT - 10.2amps, low draw but sounded absolutely fucking awful
    wobbled motor cage - still sounded SHIT - just doesn't make sense at all
    Had to shelve it on Monday & hope to look into it this weekend, likely change motor
    or investigate just WTF is up with it, never expected it to sound so crap
    after all the attention to detail & sweet it all seemed to go
    yet proof of pudding was a tin of angry wasps trapped inside a tin of rusty ol' nuts & bolts
     
    So what the fuck do I know - ignore my advice, I know completely fuck all
