Abstract
A variable timing limiting device for mounting to a camshaft variable timing mechanism includes a flange having a central opening and a travel limiter extending from the flange, wherein the camshaft variable timing mechanism has a hub and a sprocket having a recessed portion, the travel limiter being matably receivable in the recessed portion of the sprocket. In another aspect of the disclosure, a variable timing limiting device for a camshaft variable timing mechanism includes a free floating travel limiter inserted into a chamber portion of the camshaft variable timing mechanism. In another aspect of the disclosure, a camshaft variable timing mechanism for securing to a camshaft includes a hub, a vane lobe extending from the hub, a sprocket portion having a recess configured to receive an end of the vane lobe, the vane lobe being capable of travel within the recess, and a variable timing limiting device.
