giobdf 0 Posted August 12, 2015 Hello guys , I have a problem with the replacement of the strap of a u-boat U-51 chimera limited ed ... does anyone know how remove the strap? It has a spring pin or I have to unscrew the screw microscopic that there is on the sides of the loop? TKS for your help!!! Share this post Link to post Share on other sites
Marshall 0 Posted August 12, 2015 Looks like there are hexagon screws there that you need to remove to free the straps. Share this post Link to post Share on other sites
deju 1,858 Posted August 12, 2015 total Pita they are little hex screws on either side that screw into a pipe ... similar to B&R but more fiddly. Share this post Link to post Share on other sites

I tried in the store a key 0.6 mm and it was small , the 0.8 was big.... I ordered the 0.7 and if it does not work I will cry!! Share this post Link to post Share on other sites
