🛠️ Service Notes

• At 12.683 kg this sits in the same weight class as the other ~12.7 kg EVC-D servo units listed under this item type, rather than the ~20 kg or ~8 kg servo units also sold here — confirm the exact drive variant your installation uses before ordering, since weight alone does not confirm fitment
