Engine & Chassis Repair in Jenison, MI

Engine Diagnostics, Repair & Overhauls

Engines in emergency vehicles live hard lives: extended idle, heat soak, quick launches, and constant accessory loads. We start with smart diagnostics—scan-tool data, smoke and pressure testing, and mechanical checks like relative compression—to pinpoint the root cause before we turn a wrench. You’ll get plain-language findings, options, and accurate timing.

We handle cooling and lubrication issues, air and fuel delivery faults, turbo and charge-air leaks, EGR and aftertreatment concerns, plus ignition control on gas-powered support vehicles. Typical problems include hard starts, low power, overheating under load, fuel contamination, and post-overheat damage. When repair depth matters, we perform in-frame overhauls with measured bearing clearances, cylinder inspection, torque-to-yield procedures, and documented break-in steps. To verify results, we road-test, data-log, and recheck fasteners after heat cycles.

If you’re chasing intermittent faults, we track heat-related wiring opens, sensor drift, and failing modules with targeted test plans. You’ll know exactly what failed, why it failed, and how we’ve prevented a repeat.

Chassis Repair, Suspension & Brakes

A reliable chassis keeps crews safe and response times consistent. We inspect and repair steering gear, pitman and idler arms, drag links, tie rods, and kingpins, then set toe and thrust angles for proper tracking. On air-ride systems, we replace ride-height valves, bags, shocks, and bushings; on leaf-spring setups, we renew spring packs, pins, and shackles to eliminate wander and brake dive.

Wheel-end services include hubs, bearings, seals, and torque checks. For braking, we service air systems end-to-end: compressors, dryers, governors, valves, chambers, automatic slack adjusters, S-cams, rotors/drums, and ABS sensors and tone rings. We also fix frame and crossmember corrosion, cab and body mounts, and drivetrain issues such as U-joints, carrier bearings, and engine or transmission mounts that cause vibration under load.

Because fire apparatus often use PTO-driven equipment, we verify driveline angles, coupler alignment, and mounting integrity to reduce noise and premature wear. We also chase chassis-electrical gremlins—grounds, power distribution, and harness chafe—so lights, warning devices, and accessories operate as designed. Bottom line: if it steers, stops, rides, or carries weight, we can repair it and document it.

Our mobile team travels within a 100-mile radius for on-site work.

What Are Common Signs Of Chassis Wear?

Watch for wandering, uneven tire wear, vibration under acceleration, clunks over bumps, brake pull, or a crooked steering wheel after turns. Air-ride vehicles may sit low or lean if a valve or bag fails. Addressing these early prevents rapid tire wear, longer stopping distances, and added stress on steering and brake components.

How Often Should Apparatus Engines Be Serviced?

Follow manufacturer hours, mileage, and calendar intervals, but remember emergency duty cycles are severe. Short-trip idling accumulates moisture and soot, so fluids and filters may need more frequent changes. Regular inspections catch leaks, belt and hose fatigue, and cooling issues before they sideline a response or force a costly tow.
