Lufkin Gearbox Repair and Rebuild

We are a family owned shop in southwest Houston, established in 1998, and every job stays in house from teardown to test. When a Lufkin unit comes in, we strip it completely, document every clearance and contact pattern, and find the real root cause before we quote a single part. A wiped bearing or a pitted pinion is usually a symptom, not the disease, and we want to fix the disease.

Houston runs more oil and gas rotating equipment than just about anywhere, so we serve Lufkin owners across the Gulf Coast and far beyond. Free shipping both ways means distance never decides whether you call us. If you are local, we pick up, crate, and rig at no charge, and we handle the same for our oil field customers every week.

We have torn down enough of these to know the patterns. The failure mode depends entirely on whether you are looking at a high speed turbo unit or a slow oilfield reducer, and a good repair starts with reading the wear correctly.

On the high speed parallel shaft and integrally geared units, the bearings tell the story first. These run hydrodynamic tilting pad and pressure dam journal bearings with Kingsbury style thrust packs, and the babbitt is the canary. Babbitt softens around 250 to 275 degrees and begins to melt near 455 degrees, so a brief oil interruption, a varnished cooler, or a misaligned coupling will wipe a pad before anything else complains. On the gear mesh itself we find scuffing on the high speed pinion from boundary lubrication and shock load, micropitting from a marginal oil film, macropitting and spalling from contact fatigue, and in the worst cases subsurface initiated bending fatigue at the root. Thrust collar distress and shaft journal wear usually ride along with all of it.

On the Lufkin pumping unit reducers the story is slower and grittier. Herringbone teeth take the abuse of years of reversing load, water in the oil, and cold start surge, so we see tooth pitting, wear that opens backlash past spec, slow speed bearing wear, and cracked or worn output shafts where the crank arms key on. Whatever the unit, we measure tooth contact, runout, and bearing clearance against the original ratings, not against a guess.

Our shop sits at 8449 West Belfort Ave in Houston, in the middle of the densest concentration of oil and gas, petrochemical, and power generation equipment in the country. Refineries, gas plants, compressor stations, and pumping operations all run Lufkin gearing, and being local means we can pick up, crate, rig, and deliver a Houston area unit without you lifting a finger. We do free pickup and delivery for our neighbors as a matter of course.

For operators outside Houston, free shipping both ways takes the math off the table. Whether your Lufkin unit is in West Texas, Louisiana, or another state entirely, you ship it to us at no cost and we ship it back the same way. Free inspection and a free quote come first, so you know exactly what you are dealing with before any work begins. See the industries we serve and our brands coverage for the rest.
