Assembly tools or aides assist the installation of chains and sprockets for a power take off in a motor vehicle automatic transmission. A first tool is an assembly clip having a semi-circular channel that engages the periphery of a chain disposed about a socket. The clip facilitates installation of the chain and a first sprocket through a slot or other opening in the side of a transmission housing while a second sprocket is being secured to a transmission shaft and the chain is engaged thereabout. The clip also facilitates positioning of the first sprocket in a desired location, typically on a driven shaft while retaining the chain thereabout. A second tool includes a pair of elongate, parallel pins which cooperate with the clip and the first sprocket to hold it in place during assembly of certain components of the transmission such as a power take off shaft or bulkhead.

The present invention relates to a belt attachment tool used for further winding a belt, which is wound on a first pulley (1) and a second pulley (2), on a third pulley (3), the belt attachment tool containing a side surface part (10), an attaching part (11), a first belt holding part (14), and a second belt holding part (15), and the second belt holding part (15) is arranged so that a point (F) of intersection between a first extension line (L1) extending the belt wound on the first belt holding part (14) from an outer periphery of the second pulley (2) and a second extension line (L2) extending the belt wound on the second belt holding part (15) from an outer periphery of the first pulley (1) is located to a front side in a rotation direction (A) of the third pulley (3) with respect to a center line (L3) connecting a center (1S) of the first pulley (1) with a center (3S) of the third pulley.

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.

A belt assembly for a vehicle and an arrangement for a vehicle including the belt assembly are disclosed. The belt assembly comprises a belt body having at least two ends, at least one of which is loop-free, wherein the belt body is fixedly provided with a first attachment at the at least one end, wherein the first attachment forms a step with respect to at least one side surface of the belt body at the respective end of the belt body, wherein the first attachment, together with the belt body, form a first mounting end of the belt assembly. The belt assembly may have improved appearance and improved accuracy.

A belt attachment jig includes a jig body (10) located along a side surface of a pulley (1), and a belt guide portion (15) which protrudes forward in the pulley rotational direction from a contact portion (11) near one end of the jig body (10). The belt (B) is held between the twisting preventing plate (12) which forms the other end of the jig body (10) and the side surface of the jig-attached pulley (1) such that an inner circumferential surface of the belt (B) faces the jig-attached pulley (1). As the pulley (1) is rotated, the belt attachment jig is moved in the pulley rotational direction together with the belt (B) in a manner that makes the belt (B) fitted in the pulley groove.
