Three Torque Converter Problem Symptoms
Last month, we talked a bit about some of the common torque converter problems. Despite the excellent capabilities and reliability of the torque converters we provide problems do arise from time to time—especially considering the extraordinary torque converter performance your extraordinary projects require.
This month, lets take a look at a few symptoms that you can spot to detect when something has gone wrong. After all, spot the problems early on, and they’ll be much easier (and cheaper) to fix.
Here are three:
1. No Power from the Converter
You know the feeling—you ask for power, and get very little of it. A problematic torque converter can play a big part in this, because it plays a vital role in converting horsepower to torque. To get proper power from the torque converter, you need to allow enough time for converter pressure to form. If it doesn’t, you won’t get the power you need.
2. Surging and Lagging
If your machine “surges” or “lags” during operation—in other words, if it can’t seem to maintain constant speed, power, or lift—it might be a torque converter problem due to erratic converter fluid pressure or flow. This could be due to low converter fluid in the day tank and/or air present in the converter fluid circuit.
3. Power Loss due to Clutch Slippage
You’ll notice this when, especially after heavy acceleration, the clutch tends to slip. It will feel just like the converter is loosing power while all along, the engine is making power, but the master clutch assembly is not transferring power to the torque converter. A simple clutch adjustment and you can be up and running in no time. If this condition goes untreated for too long, excessive damage will occur to you master clutch assembly requiring removal and replacement. The key to saving money is maintaining your equipment and fixing problems quickly before they grow into bigger problems.
At K&L Clutch, we provide only top-of-the-line torque converters from brands like Twin Disc, Allison, Clark, American, Link Belt, and Manitowoc. But in those rare times when problems arise, our unparalleled service department can get you back up in running again in no time — whether from our home in Hurst, Texas, or just about anywhere in the world you need us to be. Take a second from time to time to inspect the torque converter for visible problems like fluid levels, pressures and clutch adjustment to catch potential problems before they exist, but know that we’re here for you when more serious problems arise.
Three Common Torque Converter Problems

Industrial Torque Converter
Industrial torque converters provide the torque and horsepower that makes your projects go—but they’re not immune to to breakdowns. Here are four common industrial torque converter problems you might run into (especially if you’re using one of the top brands we provide):
1. Overheating
The most likely problem you’ll run into, overheating can usually be directly traced to low converter fluid pressure and/or air present in the system. This can be caused by several factors: when fluid levels get too low, when the filter gets clogged, suction lines are cracked or the charging pump begins to fail. Overheating can damage the seals, o-rings and gaskets leading to fluid leaks and a lack of proper fluid circulation.
2. Deformed Blades
Fragmented or deformed turbine blades is another sure way to see an industrial torque converter quickly lose its effectiveness. This can happen as result of rapid overheating of the torque converter or contamination ingested into the system which can lead to the turbine blades beginning to break and pull away from the hubs. With extreme heat, the blades can even break into pieces. Torque converters with deformed or fragmented blades require significant and expensive repairs (or a complete rebuild) to avoid a prohibitive loss of torque converter efficiency.
3. Proper Installation
When installing a new K&L torque converter, it is best practice to install new cooler lines and have the radiator/cooler professionally cleaned. This insures that all contamination from the previous converter installation is removed from the system. If coolers and lines are not clean, then debris from the previous converter failure will be ingested into the new converter causing a very quick and costly failure.
From our home office in Hurst, Texas, we supply only the best torque converters from the best brands. But we also stock a full catalog of replacement and repair parts, can manufacture customized specialty parts from our warehouse, and can meet you with a service team just about anywhere in the world should you have a problem.

A Tale of Two Ancient Civilizations (and the Cranes That Built Them)
From construction to freight to salvaging forsaken ships at sea, cranes are simply the arms that do the heavy lifting powering our global industries. The world just wouldn’t be the same without them—and it’s our goal to make sure your cranes will perform powerfully, flexibly, and effectively until the jobs are done.
So how did cranes become such an integral part of all of our lives (whether we realize it or not)? Let’s take a look back through history:
Democracy and Devotion: Greeks Invent the Crane
Necessity is the mother of all innovation—and you won’t find a more urgent group of inventors than those under threat of being smote from above. For whatever reasons, the Ancient Greeks felt compelled to build huge temples to their gods, and traditional methods like ramps for moving and lifting the enormous building stones of massive monuments like the Parthenon just weren’t going to get the jobs done. Meet the crane: at first a simple winch and pulley system, and later a compound pulley system credited to Aristotle.
Today, you can see the difference in the way temples were built in different time periods. Pre-cranes, building blocks actually tended to be much larger, because so much effort was required to push each one up a ramp that it was less labor-intensive to use bigger and fewer blocks. Post-cranes, blocks were smaller, but stacked higher, in more complicated and advanced structures, and more quickly.
In the end, the Greeks proved just how much more ambitious projects could be with the help of a crane. The Egyptian slaves responsible for building the pyramids block by ramp-elevated block are still squirming with envy in their graves.
Mobility and Versatility: Cranes Power the Roman Empire
Rome wasn’t built in a day, but without the introduction of and improvement upon the Greek cranes, construction would’ve taken much, much longer than it did. In fact, the Romans were the first to use multiple cranes for cooperative lifting tasks, as is evident by the massive cornerstone blocks used in some of the famous structures.
But beyond the beautiful, historic, crane-built city still very visible today, perhaps the most impressive aspect of Roman crane use was the way they were used far from their home. Again—necessity drives innovation. And as the Roman Empire stretched further and further away from Rome, and as conquering armies became more and more ambitious, mobility and versatility in their cranes became key. The Roman army needed cranes that could move quickly, be assembled and torn down quickly, and perform a variety of tasks—all without losing their powerful lifting capabilities.
Today, you can see that influence in how mobile cranes are used all over the world. You find them on boats, docks, trains, and trucks, often able to be quickly adapted for difficult, unusual tasks. Lifting capacity has skyrocketed, up to 1,000 tons. In the end, the Romans proved just how much mobility and versatility multiply capability.
At K&L Clutch, we understand just how many ways your business relies on your lifting capabilities. When a crane breaks down, we can be there—just about anywhere in the world—with the industrial machine parts to get your project back on track in no time.
Three Things You Didn’t Know About Heat Exchangers
Young MOC-8 heat exchanger
Our Young MOC-8 heat exchangers help maintain oil pressure, avoid air flow resistance, and keep your machines running at peak performance better than any others in the industry.
But beyond industrial machinery, heat exchangers play several vital roles in shaping our modern world, from industry to nature to our own, fragile bodies.
Here are three facts you might now know:
1. They’re used all over the place
Anything that needs highly optimized cooling and heating, really, as heat exchangers can reduce heat loss and redirect it to other purposes. Various types of heat exchangers are used in industrial sectors like power plants, petroleum refineries, and chemical plants. They keep jet fuel from freezing at high altitudes. They make up an important part of the wine production process. And they help keep waste water treatment plants operating at optimal temperatures, fostering the growth of microbes that remove pollutants from the water.
2. A similar system can be found in… birds, fish, and whales
Basically, arteries carrying warm blood to the skin get crossed and exchange heat with veins carrying cold blood away. The result is basically a “countercurrent” heat exchanger that reduces overall heat loss in cold waters—for baleen whales when the swallow enormous amounts of water to catch their evening krill, for storks, flamingos, and other wading birds when they stand in cool water, and for fish while breathing underwater.
No word yet if anybody has modeled an industrial machine after a blue whale.
3. We couldn’t live without them
Similarly, human bodies perform heat exchanger functions in two ways: Thanks to their large surface area, the lungs help moderate and optimize the hot or cold air we breathe in, before the oxygen is passed on into the blood stream.

How Young Heat Exchangers Maintain Oil Pressure and Avoid Air Flow Resistance
Mobile oil coolers need to be durable, rugged, flexible and reliable. With that in mind, our mission to supply Texas with its heat exchanger needs came down to one brand and one brand only.
Our line of heat exchangers from Young Transmission do every job efficiently, and provide simple solutions to complex cooling problems. The mobile oil coolers come in eight standard sizes, each of which can be piped at installation in one or two pass oil flow arrangements, and boast performance ranges of 100 GMP oil flow and heat transfer capacities from 5,000 to 350,000 BTU per hour.
The result is low cost oil cooling systems with minimum oil pressure drop and low air flow resistance.
When mounted in front of in rear of engine cooling radiators, the MOC coolers make effective dual use of vehicle’s existing:
- Air stream
- Cooling hydraulic transmissions
- Torque converters
- Fluid power systems
- Lube oil
- Fluid couplings
- Hydrostatic drives
- Power steering
And when remotely mounted, Young MOC-8 heat exchangers can be used with any external air flow system for cooling process fluids.
Young’s been doing this for more than 75 years. So here are some of the superior construction elements that make Young’s heat transfer and exchange equipment so effective:
- Core: Basically, the core is the heat transfer surface, built from round steel tubes that can withstand multiple pressure shocks, plus a handful of aluminum allow fins and welded tubular steel manifolds. There’s also a permanent bond between fins and tubes, forged by mechanically expanding the tubes into specially formed fin collars (this provides double-walled continuous metal heat transfer surfaces).
- Turbulators: Young’s turbulators are inserted into each tube, which eliminates laminar oil flow. The result? Improved heat transfer by more than 100 percent.
- Mounting Brackets: Four steel “U” section outrigger brackets form the MOC’s mounting brackets. The small, but critical pieces come with multiple mountain holes to allow for maximum positioning ability.
- Connections: Young MOC heat exchangers feature both inlet and outlet oil connections with male dryseal threads. This creates a more efficient fluid flow, while still maintaining minimum pressure drop.
- Manifolds: The MOC’s manifolds are electric welded, heavy-gauge tubular steel manifolds that have drain-vent connections and plugs.
