Hyster H60 Mast Cylinder Repair in Ames, Iowa
If your Hyster H60 is dropping its forks slower than it used to, or you’re finding a puddle of hydraulic oil under the mast every morning, you’re probably looking at a worn mast cylinder. We do Hyster H60 mast cylinder repair regularly at our Ames shop, and it’s one of those jobs where doing it right the first time saves you money down the road. We’re not going to sell you a rebuild kit and send you on your way — we pull the cylinder, tear it down, and tell you exactly what we find before we put a wrench to anything else.
How We Handle Hyster H60 Mast Cylinder Repair
Every Hyster H60 mast cylinder repair job starts the same way at our bench: we remove the cylinder from the mast, drain what’s left of the fluid, and open the bore up to see what’s actually going on inside. Most of the time we’re looking at worn or extruded head seals, a scored bore from years of debris riding through the hydraulic circuit, or a piston seal that’s just given up after thousands of lift cycles. We use seal kits matched to the actual bore size — for the H60 that’s typically a 3-inch bore with head seals like the HS686-342 (3″ x 0.062″ x 3/16″), piston seals in the P-AA1062 range (3″ x 1.062″ x 3.25″), U-seals around 1-1/8″ x 1-3/8″ x 3/8″, and a wiper seal like the MCU-1500-D (1-1/2″ x 3″ x 5/16″). Getting the right seal stack matters — the wrong wiper seal will let dirt back into the bore and you’ll be back on our lift within a year.
Once the new seals are pressed in, we reinstall the cylinder on the mast, hook the hoses back up, and bleed the system to get every bit of trapped air out. Air in the line is one of the most common reasons a freshly rebuilt cylinder still feels soft or jerky on lift — we don’t call the job done until the mast moves smooth through its full range.
Common Signs Your Hyster H60 Mast Cylinder Needs Attention
We see the same handful of symptoms walk through our door on Hyster H60 mast cylinder repair jobs. Here’s what usually tips us off that a mast cylinder is on its way out:
- Forks drift down on their own when the truck is parked and idle
- Visible oil weeping or dripping around the base of the mast cylinder
- Jerky or hesitant lift, especially right after startup
- Loss of lift speed or the mast struggling to raise a full load
- Scoring marks visible on the piston rod when it’s extended
One thing we’re upfront about: it’s really common for the other cylinder to blow out shortly after we rebuild the first one, especially on a truck with high hours. Both cylinders see the same duty cycle, so if one’s worn enough to leak, the other usually isn’t far behind. If a rebuild doesn’t hold — which happens when the bore is scored too badly to seal properly — you’re looking at a new cylinder instead, which typically adds $300 to $800 depending on the cylinder size and availability. We’ll always tell you before we get to that point, not after.
How Much Does Hyster H60 Mast Cylinder Repair Cost
A straightforward Hyster H60 mast cylinder repair — remove, rebuild with new seals, reinstall, and bleed — generally runs in the $450 to $900 range, depending on cylinder size and how much disassembly it takes to get the cylinder off the mast. If the bore is scored beyond what a seal kit can fix, replacing the cylinder outright adds $300 to $800 on top of labor. We also charge mileage if we’re coming to you: it’s a flat rate for round trips within 40 miles of our Ames shop, no trailer needed for most mast cylinder work. If you want a broader breakdown of what drives cylinder rebuild pricing across different equipment, our hydraulic cylinder rebuild cost guide lays out the variables in more detail.

Frequently Asked Questions
How long does Hyster H60 mast cylinder repair take?
Most Hyster H60 mast cylinder repair jobs take one to two days once the cylinder is on our bench, depending on parts availability for the seal kit and whether the bore needs machine work. We’ll give you a firm timeline after we’ve pulled the cylinder and inspected it.
Can you rebuild my mast cylinder instead of replacing it?
Yes, in most cases a rebuild with new seals solves the leak without needing a whole new cylinder. The exception is when the bore is scored deep enough that seals won’t hold — at that point we’ll tell you straight up that replacement is the better call.
Why did my other mast cylinder start leaking right after you fixed the first one?
Both mast cylinders on a Hyster H60 see the same lift cycles and wear at a similar rate. It’s genuinely common for the second cylinder to fail not long after the first gets rebuilt, so if your truck has high hours, ask us to check both while it’s already apart.
Do you come to our location for mast cylinder work?
We do. We charge a mileage rate for round trips within 40 miles of our Ames shop, and we’ll pull the cylinder on-site or bring it back to the shop depending on how the job’s set up.
What does Hyster H60 mast cylinder repair cost if the cylinder can’t be saved?
If the bore is too scored to reseal, replacing the cylinder typically adds $300 to $800 on top of the base repair labor, depending on the exact cylinder and what’s in stock. We’ll walk you through the number before we order anything.
