Transmission diagnostic
Lubrication PM extends gear life dramatically. Reactive transmission rebuilds are expensive.
Commercial mixer gear and transmission failures cluster in three areas: speed-selector mechanism wear ($280–$540), worm-gear wear ($580–$980 on premium Hobart, $480–$720 mid-tier), and full planetary transmission rebuild ($880–$1,800) — and the single biggest driver of which one you face is whether the unit got its annual lubrication PM ($120–$180). Skipping PM moves worm-gear wear from year 10–12 up to year 6–7. The most urgent signal is a transmission oil leak: the seal repair ($180–$380) is far cheaper than the rebuild it prevents, because oil loss runs the gears dry within months. Our techs address any leak or grinding on priority. The $120 commercial diagnostic is waived when you approve the repair.
Commercial mixer gear and transmission failures cluster around three areas. (1) Speed selector mechanism (gear engagement at speed change) wear year 6-9, $280-540 service. (2) Worm gear wear (premium Hobart H600, A200) year 8-12, $580-980; mid-tier year 6-9, $480-720. (3) Planetary transmission gear set year 10-15 premium, year 7-10 mid-tier, $880-1,800 rebuild. Annual lubrication PM ($120-180) extends gear life dramatically; reactive transmission rebuild without PM is the expensive scenario.

FAQ
Speed selector grinds when changing speeds. Repair?
Yes. Speed selector mechanism wear is year 6-9 typical; grinding indicates internal gear damage starting. Service $280-540 catches it before full failure. Continued operation with grinding selector accelerates damage and may require full transmission rebuild ($880-1,800) instead of selector-only service ($280-540).
Transmission oil leak — when do I worry?
Now. Transmission oil loss damages internal gears within months. Leak source ($180-380 seal replacement) is much cheaper than rebuild ($880-1,800). We address transmission oil leaks priority on every mixer service call.
Annual lubrication PM — actually critical?
Yes. Hobart published manufacturer recommendations call for annual lubrication on H600, A200, M802. Operations skipping PM see worm gear wear at year 6-7 (vs year 10-12 with PM). The math is obvious: $120-180 annual lubrication vs $580-980 reactive worm gear replacement.
Spiral mixer bowl-rotation gear — different from planetary transmission?
Yes. Spiral mixers (Univex SRMF, Varimixer V-Series) have a separate bowl-rotation gear that drives the bowl rotation while spiral hook spins. Year 6-10 typical wear, $580-980. Different component than planetary transmission.
Worm gear vs planetary transmission — different?
Worm gear is one specific component within the planetary transmission. Some failures localize to worm gear only ($580-980 service); others involve full planetary set requiring rebuild ($880-1,800). Diagnostic determines scope.
Hobart H600 transmission rebuild — worth it on year 15 unit?
Often yes. Hobart H600 chassis is built for 20-year service life. Year-15 rebuild $880-1,400 on retail-$10K-15K mixer extends 5-7 more years of service. Math works.
My commercial mixer is making a grinding or whining noise. How urgent?
Urgent. A Hobart Legacy, H600, or A200 transmission is a sealed, heavy cast-iron design that runs quietly when properly lubricated, so a new grinding, whining, or knocking noise means something inside is wearing — most often the speed-selector gears starting to chip or a worm gear running short on oil. Continuing to run it accelerates the damage and turns a $280-540 selector service or $180-380 seal repair into an $880-1,800 full transmission rebuild. Our techs open the transmission, check oil level and the gear set, and catch it at the cheap stage whenever possible. The $120 commercial diagnostic is waived when you approve the repair.
My mixer slips out of gear or won't hold a speed. What causes that?
Grinding when you change speeds, popping out of gear, or not holding a selected speed points to speed-selector mechanism wear, typically year 6-9, $280-540 to service. The selector engages different gear ratios inside the transmission, and as its internal gears wear the engagement gets sloppy. The reason to fix it promptly is the same as any transmission noise: running it while it grinds chews up adjacent gears and can push the job from a $280-540 selector service to an $880-1,800 rebuild. Our techs service the selector before that escalation. The $120 commercial diagnostic is waived when you approve the repair.
