The SEW S77 is a helical-worm unit. A full rebuild — teardown, inspection, new bearings and seals, gear work as needed, loaded test run — typically runs $770–2,400 with a 5–10 business-day turnaround, versus $1,350–3,600 and a 16–30 week factory lead time for a new unit. Emergency 24–72 hour service is available.
Have a SEW S77 you'd rather not fix? We buy them — running, failed, or surplus-new on the shelf. Send the nameplate for both numbers: the repair quote AND the cash offer.
We repair and buy the full SEW range. See the SEW brand page or the rebuild price guide for the complete model table.
