OTC 1180 10-Ton Push Puller Set

The OTC 1180 bundles three complementary bar-type pullers in a plastic storage case: a No. 927 10-ton push-puller with a 2-1/8 to 7-1/4 inch spread and 8-3/8 inch reach; a mid-range gear and pulley puller (listed as No. 522 in feature bullets and No. 832 in the product description — likely the same tool under updated model numbering) covering 2 to 7-3/4 inches, used with 1/2-inch cap screws (not included); and a No. 7393 gear puller covering 1-1/2 to 4-1/4 inches with two forcing screw lengths (5-1/2 and 13 inches). The No. 927 push-puller uses a yoke-and-leg forcing screw mechanism through tapped holes — a different extraction geometry than jaw-type pullers — suited for harmonic balancers and components where jaw purchase is unavailable. OTC is a professional shop brand sold to dealerships; reviewers consistently note brand trust and general quality, though the available 34-review sample contains no application-specific descriptions of structural performance under named extraction loads.

The 1180 is right for a professional or well-equipped home mechanic working on heavy-duty trucks, construction equipment, or industrial machinery who encounters gear, bearing, and harmonic balancer extraction via tapped holes. The 10-ton capacity and 7-3/4 inch maximum spread are sized for HD applications beyond what standard 3-jaw passenger-car pullers address. Skip this for light-duty passenger car bearing and hub work — a mid-range 2-jaw/3-jaw passenger car puller set covers the 3 to 5 inch hub diameters typical of sedans and light trucks at a fraction of the cost. Note also: the No. 522/832 puller requires 1/2-inch cap screws that are not included; those need to be sourced separately before the tool is fully functional.

Steel hand tool — no chemical exposure in normal use; no SDS. Steel construction is highly recyclable through scrap metal channels; the plastic storage case is the only non-recyclable component and represents a small fraction of total tool mass. Penetrating oils, thread-release compounds, or bearing greases used during the mechanical operation carry their own hazard profiles — check the individual product review for guidance.
