Engine, Chassis & Pump Maintenance in Jenison, MI

Engine, Chassis & Pump Maintenance

Need reliable engine, chassis, & pump maintenance that keeps your apparatus mission-ready and downtime low? You’re in the right place—service that’s precise, transparent, and built around your response schedule.

What You Get With Routine Engine, Chassis, & Pump Maintenance

You protect your community. You deserve a maintenance partner that protects your uptime. Our team builds maintenance plans around your fleet’s run volume, duty cycles, and seasonal demands so your rigs start, pump, and steer exactly when you need them.

Engine Care That Prevents Surprises

We inspect and service cooling systems, fuel delivery, charge-air plumbing, belts, and sensors. We perform oil and filter changes using the correct specifications, check valve lash per OEM guidelines, and run battery/charging diagnostics. Where applicable, we support aftertreatment health with DPF condition checks and DEF system inspections to keep warning lights at bay and power consistent on scene.

Chassis Checks That Keep You Stable & Safe

Expect thorough inspections of steering linkage, kingpins, suspension bushings, springs, and shocks; brake lining thickness and rotor/drum condition; air system integrity and dryer performance; wheel bearings; driveline U-joints; and lighting. We address tire wear patterns and alignment concerns that lead to drift and increased stopping distance.

Pump Services that Keeps Water Moving

We evaluate primer performance, intake relief operation, pressure governor response, and packing/mechanical seal condition. We verify gearbox fluid, check impeller clearance where applicable, and test for air leaks or cavitation symptoms that can flatten stream quality. Need annual testing aligned with NFPA 1911? We’ll prepare your apparatus and coordinate the flow/pressure tests so your documentation is clean and your crew is confident.

When Should You Call?

If you notice slow cranking, intermittent power loss, brake pull, longer stopping distances, steering play, unusual vibration, suction loss, or pressure fluctuations at the panel, it’s time to schedule. Catching these early keeps small fixes from becoming big outages.

What Makes Us Different

You want a crew that simply gets it done. Our founder built this shop on a plain promise: we don’t like to turn anyone away. If you have a problem, we’ll put the right eyes on it—and we keep at least one technician available who can fix the issue and move your apparatus back toward service. That mindset is why departments trust us when the clock is tight.

The owner’s story matters, too. Born in Tasmania and raised on a working farm, he learned the trade the hard way—by keeping equipment running when downtime wasn’t an option. That practical, never-quit approach guides how we diagnose, communicate, and deliver for you today in Jenison.

For parts, you benefit from efficient sourcing and dependable components. As a Certified Parts Plus service center, we match quality parts to your apparatus quickly, control costs, and support faster turnarounds. Fewer logistics headaches for you means more time with your rigs where they belong.

Working on fire apparatus requires proven qualifications. Our EVT Master Certified technicians bring the discipline and documentation your municipality expects—clear findings, prioritized estimates, and repairs aligned with OEM procedures and industry standards. That certification level isn’t just a patch; it shapes how we verify safety-critical work and sign off repairs.

Running Toyne apparatus? You’re covered. We provide dealer-level support for Toyne products, so you can expect informed diagnostics, model-specific guidance, and the correct parts pathways. It shortens the path from “out of service” to “back on the road,” especially when your pump or chassis systems are model-dependent.

Bottom line: you’ll get straight answers, clear timelines, and repairs that respect your budget and your duty to respond.

How Often Should A Fire Pump Be Tested And Serviced?

Most departments conduct an annual pump performance test aligned with NFPA guidance to document capacity and pressure stability. Between annuals, routine checks of primer function, packing or mechanical seals, and pressure governors catch small leaks or cavitation early. Any pressure fluctuation, hard priming, or unusual vibration during drills warrants a prompt inspection.

What Are Early Signs Of Chassis Problems On An Apparatus?

Watch for steering play, shimmy under braking, or wandering at highway speeds. Uneven tire wear, air dryer purging too frequently, or longer stopping distances also indicate developing issues. Addressing these early protects stopping performance, keeps alignment true, and prevents accelerated wear on suspension and steering components.

Customer Testimonials

"Kleyn goes above and beyond in making sure you get back on the road. They have somehow found a group of a dying breed of people that put in the extra effort to make sure the job is done correctly and quickly."
- Dan

"It was our first breakdown with the motorhome we bought a year ago. Uncharted territory for us. Kleyn was able to come out the same day, the techs were no-nonsense and quickly determined we needed a new water pump (diesel engine), got the pump, and replaced it. They were efficient, polite, and did the job in a hurry."

Ned

They make sure you know what’s wrong and help you figure out the solution. 10/10 would recommend taking your car to them! I will be coming back for any or all of my car needs."
