Beluga-ga-ga-ga-ga on August 10, 2025 10:16 am I think Howitzer cranks use an ISIS BB, so you’ll probably need an appropriate puller.
Impressive_Meat_2961 on August 10, 2025 10:18 am I believe this requires a crank puller for Isis / octalink cranks. It’s essentially a standard crank puller with a larger diameter driving pin on the end. Quite commonplace and cheap to order online.
