Dango & Dienenthal Repair in Fontana
Dango & Dienenthal forging manipulators and forge-shop machines work under loads and heat that destroy ordinary drives — rail-bound manipulators, charging machines and tilting gear that have to move tons of hot steel precisely. LA Trucks and Tractors repairs their gear drives and hydraulic systems at our Fontana shop at 14166 Whittram Ave, with in-house gear manufacturing for parts that are an ocean away or no longer stocked.

How forging manipulator drives wear — and what we do about it
Manipulator equipment that reaches our bench most often shows drive tooth fatigue from repeated load reversals, slew and travel bearing wear, hydraulic cylinder scoring from scale and heat, and seal failure in forge-shop conditions. At teardown we measure gears, shafts, bearings and cylinders before anything is quoted — then renew what the measurements condemn, cut replacement gearing in-house, rebuild cylinders on our hydraulic bench, and run-check the finished assembly before it leaves Fontana.

Frequently asked questions
Can you make parts for a Dango & Dienenthal machine?
Yes — gears, shafts and wear parts are reverse-measured and manufactured in-house, which is usually faster than importing legacy parts.
Do you repair the hydraulics as well as the gear drives?
Yes — cylinders, pumps and motors are rebuilt on our own benches in the same shop, so one teardown covers the whole machine.
Do you offer rush repair?
Yes — 24-hour rush and emergency service runs every day of the year. Call (800) 821-3404 or (949) 400-2937.
