Cleveland Gear Repair and Rebuild Services
Cleveland Gear Company has built worm gearing in Cleveland, Ohio since 1912, and units carrying that name are some of the most durable speed reducers we see come through the door. At Solution Gear Co. in Houston we repair and rebuild Cleveland Gear worm reducers, helical drives, and open gear sets every week. Whether you run an M Series or WG Series worm box on a conveyor, a Millennium worm unit on a mixer, or a large RF Series drive on a pulverizer, we can tear it down, find the real fault, and put it back together stronger than it left the factory. Learn more about our full gearbox repair service and the brands we work on.
We repair and rebuild Cleveland Gear worm and helical speed reducers and open gearing at our Houston shop. Solution Gear Co. is an independent gear shop, not an authorized Cleveland Gear dealer, and we rebuild these units as an OEM alternative with free shipping both ways and free inspection.
We are a family owned shop, established in 1998, and we do all of the work in house. That matters with Cleveland Gear units because the worm gear set is the heart of the reducer, and a proper rebuild means cutting a new bronze wheel and hardened steel worm to the correct center distance and lead, not just swapping bearings and seals. When the gearing is gone, we make it. Our gear cutting capability is what separates a real rebuild from a parts swap.
Distance is not a problem. We offer free shipping both ways, free inspection, and free pickup and delivery including crating and rigging, so a plant in Ohio, Texas, or anywhere in between can send us a Cleveland Gear reducer and get back a unit covered by up to a 24 month workmanship warranty.
What Cleveland Gear builds, and what we service
Cleveland Gear, originally Cleveland Worm and Gear, was the first company in the United States to mass produce worm gearing. Over a century they pioneered overhung load worm reducers, box type housings for better heat dissipation, and one piece housings for compact units. We service the full range of what they have put into the field over the decades.
- M Series worm reducers, roughly 1.33 inch to 5.25 inch center distance, common on smaller conveyors and packaging lines.
- WG Series worm reducers, metric center distances from 40mm to 200mm, fixed ratio right angle units.
- Millennium Series worm reducers in the 5 inch to 12 inch center distance range.
- AF and RF Series larger enclosed drives up to 36 inch center distance.
- RM Series helical ratio multipliers, often stacked with M or WG units to make double reduction helical worm drives.
- Open worm gear sets from 3 inch up to 54 inch center distance, plus custom helical, bevel, spur, and planetary drives.
If you run a worm unit that has been overhauled into a double reduction package, or a large custom drive rated for serious horsepower, we can handle it. For helical and parallel shaft work we also point customers to our broader gearbox repair page.
How Cleveland Gear worm reducers actually fail
Worm reducers fail in predictable ways, and after years of tearing them down we know where to look first. The single most important fact about a worm drive is that the bronze worm wheel is sacrificial. It is intentionally softer than the hardened steel worm so that wear concentrates in the part that is cheaper to replace. That design is smart, but it means the wheel is always the first thing to go.
- Bronze wheel pitting and wear. Sliding contact against the steel worm slowly removes bronze. As the tooth profile thins, backlash climbs, the unit gets loud, and eventually it can begin to back drive under load. We measure the wear before deciding whether the wheel can be reused, and most of the time it cannot.
- Worm shaft thrust bearing collapse. The worm carries an axial thrust force roughly equal to the tangential load on the wheel, so the thrust bearings work hard. When they fail or were never preloaded correctly, the worm floats axially, contact pattern wanders off center, and wear accelerates fast.
- Worm scoring and pitting. Worm gearing runs almost entirely on sliding, not rolling, so it lives and dies on lubrication. When the oil breaks down or runs low, you get scoring scratches along the slide direction and shiny galled patches on the worm thread.
- Shaft and seal wear. Output shafts wear at the seal journals and keyways, and leaking seals starve the gearing of oil, which loops right back into wheel and worm damage.
When the thrust and radial bearings are the root issue, our dedicated bearing repair work restores the housing fits and bearing seats to spec so the new bearings actually carry the load they should.
How we rebuild a Cleveland Gear unit stronger than OEM
Every Cleveland Gear reducer that comes in gets a full teardown and a free inspection before we quote anything. We document the wear, check the housing bores, measure the center distance and lead, and find out what really killed the unit instead of guessing.
When the gearing is worn out we cut a new set. We machine a fresh bronze worm wheel and, when needed, a new hardened and ground steel worm to the original center distance and ratio, so the rebuilt unit matches the footprint and mounting of the one you sent. Worn shafts are built up and remachined or replaced outright, bearing seats are restored, and new thrust bearings are installed and preloaded correctly so the worm does not float. We use upgraded materials and modern bearings where it makes sense, which is how we deliver a unit that is rebuilt stronger than OEM rather than just returned to factory minimum.
Because we do the gear cutting in house, we are not waiting on a parts catalog or a discontinued component. If Cleveland Gear no longer stocks a part for an older unit, we make it. The finished reducer is run, inspected, and backed by up to a 24 month workmanship warranty.
Industries that run Cleveland Gear, and why a Houston shop fits
Cleveland Gear worm and helical drives show up across heavy industry. We see them on conveyors, mixers, fans, cranes, and pulverizers, and in steel production and processing, construction equipment, and oil and gas. Many of those are exactly the industries we serve from Houston every day, so the failure patterns are familiar to us.
If your Cleveland Gear unit runs in the oil field or in mining equipment, downtime is expensive and a fast, correct rebuild matters more than anything. Free shipping both ways and free crating and rigging mean you can ship us a heavy worm reducer from any plant without it costing you freight in either direction. See the full list of industries we support.
What we repair and rebuild
What we fix.
Damaged steel worms
We machine, harden, and grind replacement worm shafts when the original is scored, pitted, or galled from lubrication breakdown.
Collapsed thrust bearings
We replace and correctly preload the worm thrust bearings so the worm no longer floats axially and the contact pattern stays centered.
Worn output and input shafts
We build up or replace shaft seal journals and keyways that have worn, then remachine the bearing seats back to spec.
Housing bore and seat wear
We restore worn bearing bores and housing fits so new bearings seat tight and carry the axial and radial loads as designed.
Helical and double reduction drives
We repair RM Series multipliers and double reduction helical worm packages, and we recut helical gearing when it is pitted or chipped.
Leaking seals and oil starvation
We replace seals, correct the lubrication path, and address the wear that leaking and low oil caused inside the gear set.
Open worm gear sets
We replace and cut open worm gearing across the large center distance range Cleveland Gear is known for, including older discontinued sizes.
Common questions
What plants ask us.
Are you an authorized Cleveland Gear dealer?
No. Solution Gear Co. is an independent gear repair shop and we are not affiliated with or authorized by Cleveland Gear Company. We repair and rebuild Cleveland Gear units as an OEM alternative, and we name the brand only to describe the equipment we service.
Can you make parts for older Cleveland Gear reducers?
Yes. We do all gear cutting and machining in house, so when a worm wheel, worm shaft, or other component is worn out or no longer stocked, we make a new one to the original center distance, ratio, and lead. You are not dependent on a parts catalog.
How does the free shipping both ways work?
We cover freight in both directions, plus free pickup and delivery including crating and rigging. You can ship us a heavy Cleveland Gear worm reducer from anywhere in the country and it costs you nothing in freight to get it here or back.
What is the most common Cleveland Gear worm reducer failure?
The bronze worm wheel is sacrificial and wears first by design, so worn or pitted wheels with excess backlash are the most common issue we see, often together with collapsed worm thrust bearings and scoring from lubrication breakdown.
What warranty do you offer on a rebuilt unit?
We back our rebuilds with up to a 24 month workmanship warranty. Every unit is torn down, inspected, rebuilt, and test run before it ships back to you.
