Motion Pro Crankshaft Puller Tool 08-0631

Motion Pro Crankshaft Puller Tool 08-0631

Product Description

Assembling a high-performance bottom end requires seating the crankshaft into the engine cases without introducing destructive lateral forces. The Motion Pro Crankshaft Puller Tool is a precision workshop device engineered to pull press-in crankshafts smoothly into the main bearings. By avoiding the unsafe practice of hammering on the crank web or using an unguided shop press, this professional-grade tool ensures your critical tolerances are maintained, providing the ultimate dedicated crankshaft puller setup for meticulous engine builders.

CNC-machined from premium billet aluminum with a durable blue anodized finish, the tool body is paired with heavy-duty steel adapters for robust longevity. The kit features interchangeable 25 mm and 40 mm face plate adapters that square up flush against the crankcase surface, ensuring the crankshaft is pulled perfectly straight. It also includes a reversible pull stud equipped with both M10x1.25 and M12x1.25 threads, alongside a universal steel nut adapter configuration that interfaces seamlessly with virtually all modern powersports crankshaft snouts.

Frequently Asked Questions

Q: Does this tool pull the two crankcase halves together, or does it install the crank?
A: This tool is designed specifically to pull the crankshaft snout through the inner race of the main bearing. While it seats the crank firmly into the case half, a separate case assembly tool or standard perimeter bolts are used to pull the matching case halves together over the transmission.

Q: Will this puller kit work on both 2-stroke and 4-stroke dirt bike engines?
A: Yes, as long as the crankshaft thread matches the provided M10 or M12 studs, or utilizes the universal nut adapter, it works perfectly on off-road, street, ATV, and UTV engines.

Expert Pro-Tip: Before using your 08-0631 puller, freeze your new crankshaft overnight and gently warm the inner race of your pre-installed main bearing with a heat gun right before assembly. This thermal trick creates a temporary slip-fit tolerance. When you thread the tool on, the crankshaft will glide effortlessly into place with minimal mechanical resistance, ensuring you place zero unnecessary stress on the precision thrust washer or aluminum tool threads.
