Thorstone 46pcs Harmonic Balancer Puller Set
This multi-function kit suits harmonic balancers, flywheels, crankshafts, steering wheels, pulleys, and similar two- or three-hole applications. It is built with heat-treated carbon steel and oxide finishes to resist rust and handle tough pulling jobs. The 30 bolts and four-yoke slot provide broad compatibility for cars, trucks, SUVs, and small engines. Best for shops or DIYers needing a single, versatile set. Caution: verify bolt pattern compatibility with your specific vehicle before use.
Flywheel Puller Removal Tool 91-849154T1
This set is focused on Mercury/Mariner outboard engines, offering a flywheel puller with crankshaft protection and a lifting ring. It fits most 45HP outboards and newer Mercury/Mariner/Force/Yamaha models with 1 1/2″-16 TPI threads. Best for boat owners replacing stators, triggers, or moving motors without damage. Limitation: verify that your outboard’s thread specification matches 1 1/2″-16 TPI before purchasing.
91-849154T1 Flywheel Puller & 91-90455-1 Lift Ring Set
This 4-piece set includes the flywheel puller with a crankshaft protector plus a lifting ring. It targets Mercury, Mariner, Force, and Yamaha outboards from the 1960s to present, with OEM-size precision threads. Best for users who need both removal and safe lifting capabilities in one package. Caution: ensure the lifting ring threads match your motor’s lifting eye specifications to avoid incompatibility.
59 Pcs Harmonic Balancer Puller Kit
This upgraded 59-piece set expands compatibility with multiple bolt sizes, including M16, M14, M12, and various UNC/UNF threads. It includes a puller forcing screw and a bearing puller plate with six-way slotted holes for precise alignment. Best for those who need a broad range of bolts and a thrust-bearing design to minimize shaft end damage. Limitation: ensure the included bolts match your vehicle’s thread pitch to avoid cross-threading.
Harmonic Balancer Puller Kit, 46 Pcs
This kit focuses on two- or three-hole applications with four yoke slots and 30 bolts for a flexible puller setup. It’s a practical choice for technicians dealing with diverse pulley configurations across several vehicle types. Best for cost-conscious buyers who still need reliable interchangeable hardware. Caution: verify your exact yoke pattern to avoid misalignment during pulling.
Buying Guide
What should I look for in an outboard flywheel puller kit?
Key factors include bolt pattern range, thread sizes, and whether the kit includes a lifting ring or crankshaft protector. A versatile set with multiple hole configurations and a robust construction (heat-treated steel) reduces the risk of damaging engine parts.
Is compatibility with outboard engines important?
Yes. If you service Mercury, Mariner, Force, and Yamaha outboards, prioritize kits explicitly listing these brands and 1 1/2″-16 TPI threads. For multi-application vehicle use, check for both metric and standard bolts and broader hole configurations.
What about protection and ease of use?
Cranshaft protectors and thrust-bearing designs help prevent damage to shaft ends during removal. Lifting rings are beneficial for safe handling when moving a loaded motor. Consider a set with clear assembly instructions to minimize errors.
How many pieces do I need?
Smaller projects may be fine with a 4–6 piece kit focused on one application. More complex jobs or routine maintenance benefit from 30–60 piece sets that cover harmonic balancers, flywheels, pulleys, and steering wheels.
Are there any downsides to watch for?
Some kits include many bolts in sizes you may not need. Ensure the included hardware matches your specific vehicle or engine. Also, verify the presence of a crankshaft protector to reduce risk during removal of stubborn flywheels.
