Complete central drive spool.
Includes grade 5 titanium center spool shaft, two 6mm bore hardened steel drive cups, two hybrid ceramic bearing and 4 piece spur gear spacers.
Spool shaft is 8mm diameter to take standard 8mm bore spur gears (NOT INCLUDED!). The 4 piece spacers are designed to give a few spacing options including Arrma or Saga spur gears. Other spur gears may be different widths and may require different spacers.
Like other drive components, these require degreasing and application of high strength loctite (including on the drive cup bore) if you want them to stay together.
Bearings are usually supplied oiled, but please check and oil them yourself. The oil that comes in them is quite thick. The bearings spin freely when dry or with very light oil. We sell an oil and hand applicator elsewhere on this website.
