What a One-Day Wet Kit Installation Looks Like

If you already know your truck needs a wet kit, the next questions aren’t about what one is — they’re about what happens on install day, how long the truck is down, and what moves the number on the quote. This page is the honest walk-through of how a wet kit installation runs at our shop in Ames, from the first phone call to the handoff. (Still deciding whether you need a kit at all, or what kind fits your trailer? Start with our main wet kit installation page, then come back here to see how the work actually goes.)

It Starts With a Phone Call, Not a Wrench

The single biggest factor in whether your truck is down one day or three is a ten-minute spec call before it ever shows up. We’ll ask what trailer or trailers the truck will power, what transmission it runs, how you use the truck day to day, and where you’d like the tank and the controls to live. From that call we order and stage everything — so when your tractor rolls in, the parts are on the bench, not on a delivery schedule. A one-day wet kit installation is really a three-day job where two of the days happened before your truck arrived.

Morning: PTO and Pump Install

The truck goes in the bay first thing. The PTO and pump install is the morning’s work: the power take-off gets mounted and adjusted on the transmission aperture, the pump gets hung and aligned, and engagement gets verified before a drop of oil goes anywhere. This is the part of the job where patience pays — a PTO that’s rushed onto the truck is a comeback waiting to happen, and comebacks cost you a second day of downtime that a careful morning prevents.

Midday: Tank, Lines, and Controls

Midday is plumbing and mounting. The reservoir goes on the frame where we agreed on the spec call — and where the truck actually has room, because exhaust, DEF tanks, battery boxes, and fairings all compete for rail space. Hoses are cut and crimped in-house, then routed and secured away from heat, moving parts, and pinch points, because a line that chafes through at highway speed undoes the whole job. The control console gets mounted in the cab where you can reach it without leaving the seat, and the plumbing gets tied through so the trailer will do exactly what the handle says.

End of Day: Oil, Test, and Walk-Through

No wet kit installation leaves this shop untested. We fill the system, engage the PTO, and cycle it — against your trailer if you brought it, which is exactly why we ask you to. Every fitting gets checked again warm, because a joint that seals cold can seep once the oil has temperature in it. Then your driver gets a walk-through: how to engage it, the habits that keep the system healthy, and what to keep an eye on for the first week. You leave knowing how to run it, not just owning it.

What Moves the Price

Every truck quotes a little differently, and these are the wet kit installation cost factors that actually move the number:

• Pump type. A simple gear pump setup and a piston pump setup are different jobs — the piston system adds plumbing and components.
• Tank size, material, and mount style. Bigger, aluminum, or an unusual mounting position all add to it.
• Line count. More lines means more hose, more fittings, and more routing time.
• Cab controls. A basic valve handle and a full console are different install days.
• The truck itself. A crowded frame rail or a tight transmission aperture adds fitting time that an open rail doesn’t.

What we won’t do is surprise you. The spec call produces a firm price before the truck comes in, and that’s the price — you say yes to a number, not to an estimate that grows in the dark.

What to Bring on Install Day

Bring the trailer if you possibly can, so the system gets tested against the equipment it will actually run — that’s the difference between “it cycles” and “it’s proven.” Bring whatever you know about the truck’s transmission if it’s new to you, and bring your opinions about where you want the tank and controls if they’ve changed since the spec call. That’s it. The parts, the plumbing, and the plan are our job.

Downtime, Pickup, and Getting on the Schedule

Spec’d ahead, most installs are a single working day — drop the truck in the morning, pick it up ready to work. Can’t spare a driver for the round trip? Our free pickup and delivery within 60 miles of Ames covers install jobs too, and a couple of photos of your frame rail texted to 515-292-2599 helps us confirm fit before the schedule is even set. If the truck needs other work while it’s here — toolboxes, mounts, anything on the upfit side — our truck upfitting crew can fold it into the same visit, and if an existing PTO needs attention first, that’s covered under PTO and driveline repair.

Ready to put a date on it? Call or text Ames Hydraulics at 515-292-2599, or stop by 210 Freel Dr, Ames, IA 50010, Monday through Friday, 7AM–5PM. One spec call, one shop day, and the next wet kit installation on our schedule is pulling your trailer by tomorrow.
