Right Angle Drive Repair
Right angle drive and right angle gearbox repair — bevel gears, bearings, seals and shafts rebuilt, including cooling tower gear drives. Pickup & delivery to our shop, nationwide.
Right Angle Drives That Turn the Corner — and Keep Turning
A right angle drive takes power in one direction and sends it out at 90 degrees — to a cooling tower fan, a conveyor head, an agitator or a mixer. When its bevel gears, bearings or seals wear out, you get noise, heat, vibration and, eventually, a stopped fan or line. We rebuild right angle drives and right angle gearboxes to restore quiet, cool running.
Right Angle Drive & Right Angle Gearbox Repair
The heart of a right angle drive is its bevel gear pair — straight, spiral or hypoid — and that pair is only as good as its setup. We check the tooth contact pattern, backlash and bearing preload, and replace worn gears, bearings and seals. Shafts scored by failed seals are repaired or remade, and housings are checked for worn bearing bores that let shafts wander out of mesh.
We have repair experience with right angle drives from many manufacturers, including units used on cooling towers. We are an independent repair shop, not an authorized agent for any manufacturer, and we work to the unit's original specifications.
- Bevel gear pairs: straight, spiral and hypoid — inspected, replaced or manufactured
- Bearings & seals: full replacement, correct preload and end play
- Shafts: repaired, re-ground or made new
- Housings: checked for cracks, wear and bore condition
- Cooling tower gear drives: see below
- 24-month warranty on our rebuild work
Cooling Tower Gear Drive Repair
Cooling tower gear drives live a hard life: constant duty, heat, moisture and fan vibration, often in a corrosive atmosphere. The usual failure pattern is seal leakage that lets water in and oil out, followed by bearing damage and bevel gear wear.
What We See in Cooling Tower Drives
We rebuild cooling tower gear drives — including units from Marley and SPX — with attention to the things that kill them: seals, bearings and the bevel gear mesh. Worn seals are replaced, shafts are checked where seals ride, bearings are replaced, and the bevel pair is inspected for pitting and wear. If a gear is too worn to reuse, we can manufacture a replacement. We are not affiliated with or authorized by Marley or SPX; we repair their equipment based on our own inspection and measurement.
Because a cooling tower drive failure can shut down process cooling for a whole plant, many customers send us a spare to rebuild while the installed unit keeps running — then swap during a planned shutdown. Ask us about that when you call.

Signs Your Right Angle Drive Needs Attention
A whine that rises with speed, oil leaking from the input or output seals, heat you can feel through the housing, vibration at the fan, or backlash you can feel by hand at the output shaft — any of these is worth a look before the bevel gears are damaged beyond repair.
Noise & Vibration
Often worn bearings or a bevel pair that has lost its mesh pattern. Caught early, it is a bearing job; left alone, it becomes a gear job.
Oil Leaks
Hardened seals and scored shafts. We replace the seals and repair the shaft surface so the new seal actually seals.
Heat & Backlash
Excess backlash and heat point to worn gears or bearings. We measure, report, and rebuild to restore proper clearances.
