Two dimensions matter: capacity (the force the puller can apply, in tonnes) must match or exceed the breakaway force of the press-fit; reach and spread (the puller's working envelope) must accommodate the component dimensions and clearance to surrounding parts. As a guide, car pulleys and small bearings typically need 2-5 tonnes; larger hubs and heavy bearings need 10-15 tonnes; commercial-vehicle and plant components need 15-30 tonnes hydraulic. Match by component dimensions and difficulty of release.
A puller uses a screw or hydraulic ram to apply controlled steady force — the standard for breaking interference fits where steady pressure progressively releases the part. A slide-hammer extractor uses a sliding weight that the operator strikes against a stop — applying impact force in pulses. Slide hammers are useful for blind bearings (where there's no shoulder to grip behind), inner-race bearings, and components in confined spaces where a puller can't be fitted.
Yes. Replacement centre screws, jaw assemblies, hydraulic ram service kits, and adapter cups are available for the majority of Sykes Pickavant puller kits. Search by the kit model code. If the part is not listed, WhatsApp 07754288583 with the model code and a photograph and we will confirm parts availability.
Harmonic balancers typically need a three-jaw puller with the jaws gripping the outer-diameter sealing surface or a dedicated harmonic-balancer puller that bolts to the threaded holes on the balancer face (where the engine is designed for this). Avoid gripping on the rubber damping ring — it will tear out and damage the balancer. The recommended puller approach for each application is normally listed in the engine workshop manual; the puller product page describes the suited applications.
Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you.
