st_lupo Posted December 1, 2017 Report Share Posted December 1, 2017 Hi all, I realize I've got two strikes against me from the start (non TD bindings and a European board), but here goes... I just bought a used Kessler 162 sight unseen, and received it not to long ago. There has obviously been a plate system mounted on it previously. I'm just trying to mount a pair of F2 Race Ti bindings and the stock screws are not long enough for the job. It looks like there is a lot more material above the threads of the 4x4 inserts than I'm used to and the stock F2 screws get probably get a max engagement of 1.5 threads. I obviously can't ride the board like this... So the two question are: 1) I though that 4x4 was a 4x4 so I'm surprised that these screws don't work... Can I use my Race Ti bindings without a plate on this board, or are the inserts designed to support a plate? 2) If I can use my bindings, what is the proper screw dimension? ok three, questions. it's actually three questions 3) What do all of the numbers mean in the first of the attached picture? Thanks for any help! Quote Link to comment Share on other sites More sharing options...
SunSurfer Posted December 2, 2017 Report Share Posted December 2, 2017 (edited) Those look like absolutely standard 4x4 binding inserts. Your bindings should be fine. You can work out the screw shaft length required by taking an M6 screw of say 20mm length. Screw it gently into the inserts all the way till it JUST stops. DO NOT OVERTIGHTEN. Measure how much of the shaft (do not include the head of the screw) is above the surface of the board. 20mm minus that distance is the length of shaft you need. I'm assuming you have the standard alloy plates that come with F2 bindings, like the one below. The thickness of the alloy and the rubber gasket under the binding will prevent you bottoming out in the insert when you crank the screws up tight with the binding in place. I have often needed to create custom length screws to get the correct size. (This disc has had some modifications to allow Burton 3 point inserts to also be used) Edited December 2, 2017 by SunSurfer Quote Link to comment Share on other sites More sharing options...
drschwartz Posted December 2, 2017 Report Share Posted December 2, 2017 Hardware store, stainless M6 screw about 3-4 mm longer than the ones you have. If they happen to bottom out, cut them slightly shorter or add a washer on top of the binding plate. Quote Link to comment Share on other sites More sharing options...

yamifumi Posted December 3, 2017 Report Share Posted December 3, 2017 I had exact same problem when i had kessler. I had white kessler and it had thick Ptex and stock F2 binding screw was too short. I bought exact same size screw but longer. Just make sure you dont by too long and damage the bottom. Quote Link to comment Share on other sites More sharing options...

slapos Posted December 3, 2017 Report Share Posted December 3, 2017 on the numbers: 11,46 - looks like radius to me 4x4 upm4 - i bet you there is a universal plate mount around your standard 4x4, underneath the topsheet 50 - seems like stance 260/239 - tail/nose width - dont know which is which, take a measuring tape and see if thats right 200 - waist width - same here take a measuring tape 70.1 - probably the recommended rider weight? plate marks - looks like vist to me or kessler kplate world cup - mounted directly to 4x4 let me know what did you find out - as last resort you can always write to Hansjorg Kessler - he will be able to help for sure.

skategoat Posted December 5, 2017 Report Share Posted December 5, 2017 I used to get this question a lot and without a single exception, the problem was that the user was not pushing down hard enough on the centre disc to engage the screws. Be very careful about getting longer screws. I've seen more than one brand new board with screws punched through the base. Quote Link to comment Share on other sites More sharing options...
Corey Posted December 5, 2017 Report Share Posted December 5, 2017 You want 3 full turns of screw engagement. Agreed that sometimes the F2 rubber ring needs some encouragement to seat, but sometimes the screws really are too short. For F2 bindings I like to screw them tight, then put a dot on the screw with a felt pen. Then unscrew while counting. When it pops up, your count is your thread engagement.

Tanglefoot Posted December 5, 2017 Report Share Posted December 5, 2017 st_lupo, you seem to have a sixpack of Aass on your waxing table. Is this for flex calibration or for something else? Quote Link to comment Share on other sites More sharing options...
st_lupo Posted December 6, 2017 Author Report Share Posted December 6, 2017 the stock screws are definitely too short. The discs are still seated in the bindings from last year when they were on an F2 Silberpfeil. For giggles I took a calipers and measured the depth to the opening of the first thread and the Kessler is a hair over 2mm deeper than both my Coiler and Silberpfeil. Yes, that Aass Fatøl was to provide an easily relatable length scale . In my house it is called by it's proper name Fat Ass beer While we're on the topic of bindings, I've always been a little unclear as to the different mounting schemes beyond 3-D, 4x4 and Burton's channel system. Below is a picture of 6 Kesslers with apparently 3 different hole patterns (for plates). Can anybody clue me into what the different hole patterns are? .
