A mounting method for an anti-detachment elastic retaining ring is provided. A mounting device includes a guide sleeve and a target mounting shaft that is provided with a groove; the guide sleeve includes a conical section; the conical section includes a narrow end with a radial dimension less than a locking diameter of a retaining ring body and a wide end with a radial dimension greater than the locking diameter of the retaining ring body; the guide sleeve is coaxially coupled with a front end of the groove of the target mounting shaft; the wide end of the conical section faces the groove; the mounting device further includes a pressing sleeve; the pressing sleeve is fitted outside the guide sleeve and moveable axially along the guide sleeve; and a side of the pressing sleeve close to the target mounting shaft is provided with a release protrusion.

A system for attaching a PTO yoke to a tractor PTO output shaft comprises gripping a shaft of the PTO yoke using a clamp tool, whereby the clamp tool maintains a slide collar of the PTO yoke in a retracted position with respect to the yoke shaft, such that the yoke shaft is exposed for attachment to the tractor PTO output shaft. The clamp tool may comprise pliers, including plier jaws and plier handles; and a flexible band coupled to the plier jaws.

A manufacturing assembly for installing a snap ring into a bore of a multi-axial joint includes a ram tool configured to axially force the snap ring through the bore towards a retention groove with the snap ring in a constricted configuration. An axially distal end of the ram tool includes one or more engagement elements having a tapered engagement surface configured to apply a radially outward force to the snap ring during passage thereof through the bore to urge the snap ring to expand from the constricted configuration back towards an original configuration upon the snap ring reaching the retention groove. A funnel tool configured to constrict and the direct the snap ring into the bore includes an alignment key configured for reception within a keyway of the ram tool during installation of the snap ring to orient the funnel tool and the snap ring relative to the ram tool.
