It&#8217;s been a challenge finding technical information, as Quaife has nothing other than an exploded diagram, and Radical has moved on to the slight bigger Q72 for the latest SR8s. Still, after a lot of searching I&#8217;ve found that the pinion depth should be 109.9mm, the differential bearing preload should be 12-15 Nm, and the backlash should be between .004-.008 inches. I&#8217;ve worked out how to measure and set up the pinion depth, and I&#8217;m working on the preload and backlash set up now. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I made the following video about pinion depth and how to measure it in the gearbox:<\/p>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"584\" height=\"329\" src=\"https:\/\/www.youtube.com\/embed\/m1qgjNNnIKo?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en-US&#038;autohide=2&#038;start=6&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span>\n<\/div><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">I&#8217;ll be posting more videos about the rest of the gearbox refresh process. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>I refreshed this box two years ago, and it&#8217;s back for another look.
