Here is a video from the Global Cycling Network showing the process of installing a Square Taper Bottom Bracket and Chainset on a Track Frame, please note the video shows a Campagnolo Chainset as an example however the process is the same for all Square Taper Bottom Brackets and Chainsets. The video also shows a “dry-fit” with no grease or lubrication, you would obviously need to grease and lubricate all parts.
