Abstract: A multi-axis tool for pre-tensioning a camshaft-drive element tensioner in an engine includes a housing having first and second faces and a length. The housing defines a first passage arranged along a first axis and a second passage arranged along a second axis. The second axis is parallel to the first axis and each passage extends through the length of the housing. The tool also includes a first lug arranged on and extending beyond the first face. The first passage extends through the first lug. The tool also includes a second lug extending beyond the second face and arranged along a third axis that is parallel to the first axis. An indicator rod is arranged partially within the second passage and configured to selectively extend beyond the first face. An elastic element is arranged inside the second passage and configured to extend the indicator rod beyond the first face.

Abstract: A camshaft assembly for a vehicle engine includes a camshaft member, a cam phaser and a cam nose. The camshaft member includes a front end and a rear end. The camshaft member may be configured to actuate at least one intake valve of a combustion chamber. The cam phaser affixed to the front end of the camshaft member while the cam nose may be disposed at the front end of the camshaft. The cam nose further includes a cam nose face with a curvilinear groove surrounding a central axis region of the cam nose. The curvilinear groove may be configured to engage with the cam phaser to prevent oil leakage out from the central axis region and/or to rotationally lock the cam phaser to the camshaft member.
