How do I increase or reduce spring tension?

To increase spring tension:

Adding wraps of hose will increase spring tension. This can be accomplished by pulling out approximately 10 feet of hose, hand feed hose back up through roller bracket assembly* until loop is large enough to slip over spool. Add two or three wraps until desired tension is achieved. Do not exceed spring capacity.

To reduce spring tension:

This can be accomplished by removing wraps of hose from the reel spool. Remove wraps of hose from the sheave, one wrap at a time, until desired tension is obtained.

*For dual pedestal reels, you will have to remove the bumper and control handle then feed the end of the hose through the roller bracket assembly to add or remove wraps of hose from the reel drum.

Can my spring driven reel be made constant tension?

Most Reelcraft spring retractable reels can be made constant tension by removing the latching system. There are some models that may not have this capability.

Please refer to our online tech bulletins for more information on converting your reel to constant tension.

How do I install a new drive spring and set pre-turns?

We have several different types of spring-driven reels. Each requires a slightly different set of instructions. For “How-To” instructions on replacing a drive spring, please have your reel model or drive spring number available and consult customer service for instructions.

For how many wraps of “pre-tension” to put on the reel, please reference the chart below.

How many GPMs will I get from my hose?

GPM = gallons per minute is a function of hose diameter, hose length, supply pressure and fluid going through the hose/reel. The most common fluids, air and water, can be seen in charted data. For hydraulic oils, it is necessary to know the operating temperature, pressure and fluid viscosity.

When it comes to maintenance on your reels, replacing the hose is a necessary part of upkeep. A hose gets worn out, overused, tugged on, dirty, ripped, weak, and just old over time. Your hose will be ready to retire way before your reel and you’re typically not going to buy a whole new reel just for the hose. Which is why you replace the hose. This task can be a bit intimidating if you have never done it before. But we are here to walk you through each and every step.

Step 1 – Removing the old hose

When it comes to replacing the hose, you must follow safety protocol for your shop or facility. This could require PPE (personal protective equipment) such as safety glasses or other cautionary actions that you feel are needed to be safe. Secondly, you need to turn off any supply lines connected to the reel or hose and bleed the hose. Once all of this is completed, pull the hose completely off the reel and lock the reel. Make sure your reel is locked. If you let go of the hose and the reel is not locked, nothing is stopping the hose from flying back onto the reel. This is a dangerous situation and can cause injuries.

Step 2 – Removing the U-bolt

Once the reel is locked, check to see if your reel has a U-bolt. The U-bolt holds the hose to the spool of the reel ensuring that if the hose gets over extended, the hose will not pull on the swivel. If your reel has a U-bolt, make note of its location as you will most likely be putting it back into this location. Once the U-bolt location is noted, remove the U-bolt with a proper sized socket.

Step 3 – Prepare the new hose

Once the U-bolt is removed, you can begin using a proper sized wrench and remove the hose from the reel. Once the hose is removed and you are ready to replace the old hose with the new hose, lay the new hose out directly in front of the reel. Remove the bumper stop from your old hose and set aside for later. Make sure the new hose is in a straight line in front of the reel. Apply appropriate thread sealant to your new hose if necessary for your application. Once the hose is straight in front of the reel and has the appropriate thread sealant, you can begin to install the new hose.

Step 4 – Install the new hose

Install the new hose by feeding it through the roller guides, the spool assembly, and into the swivel assembly. Thread the new hose onto the swivel using the same proper sized wrench. Recharge your system and check for leaks. If there are no leaks, verify your U-bolt is in the correct location. Reattach your U-bolt. Be careful not to over tighten it. Make sure the U-bolt is snug enough that the hose will not move but not so tight as it will pinch and damage the hose.

Step 5 – The end!

To finish, attach your bumper stop at your desired location. Once your bumper stop is reattached, unlatch your reel and walk the hose back until the hose is completely back onto the spool. Attaching the bumper stop before retracting the hose back onto the reel eliminates the possibility of the hose slipping back through the guide arms and losing all tension.

Now you have a brand new hose on your reel! To get a visual of these steps you can watch our “How to Install the Hose on a Spring Retractable Reel” video on our Technical Videos page.
