Roller working side

I'm replacing the deck on a Horizon DT850. The side rails don't loosen when struck with a mallet. Is the rail fastened to the frame? Or should I just hit it harder?

How can I remove the deck to replace the belt?


Hi There, yep, you're right, most treadmills allow the deck to be unscrewed from the topside, but some are installed from the bottomside. Screws under the rails. Here's a trick ;o) Usually.....
a servicer can remove the front roller on the side that doesn't have the drive belt on it, which comes off anyway, but should give you more room to see things. Then, try to gently lift one-side of the deck enough to slip the old belt off and the new belt on if there are no frame rails in the way. It's much easier with two people. Rollers may need to come off to get that deck off. What make of treadmill?

Tri Flex Deck Spring Bumper Kit Installation Instructions


Following are instructions on installing the tri flex deck spring bumper kit for the Quinton 3.0, Clubtrack, Clubtrack Plus, MedTrack CR60 and MedTrack SR60 treadmills.
  1. Set the treadmill to 5% grade and turn off the circuit breaker. Unplug the treadmill power cord from the outlet.
  2. Remove the front trim cover, hood, and both side rail covers.
  3. Relax the tension on the walking belt by removing the two screws in the rear end caps and the end caps.
  4. Remove the rear roller, then the front roller.
  5. Remove the walk belt and deck.
  6. Remove the compression mounts noting the position of the short and long mounts.

Replace deck on Precor 9.45i


Replacing a Treadmill Running Belt and Deck Following is a basic guideline of removing and replacing the running belt and deck on a treadmill. Due to different brands and designs of treadmills, the following should only be used as a guideline. If any of the information is not exact to the treadmill being serviced, refer to the service manual or call Sportsmith for further help. Tools Needed: Phillips Screwdriver, Set of Allen Wrenches, Set of Box End or Open Face Wrenches (Tools needed may vary depending on treadmill. )
  1. Switch the Power off on the unit.
  2. Next, unplug the unit from the wall.
  3. Remove the finger guard retaining screws and carefully remove the finger guards from the deck at each end of the rear roller.
  4. Loosen each rear roller bolt by 10 full turns. Then count the remaining turns necessary to remove the rear roller bolts. Remember to write down the number of turns needed to remove the bolts in each side for future reference.
  5. Carefully remove the rear roller from the unit. Clean any wax or debris buildup from the roller and place it aside.
  6. Raise the shroud and secure it with a bungee cord.
  7. Work the drive belt off the motor pulley by hand turning the flywheel while pushing the belt aside.
  8. Now remove the front roller retaining bolts.
  9. Carefully remove the front roller from the unit. Clean off any wax or debris buildup and set it aside.
  10. Loosen and remove the deck mounting hardware.
  11. Move the deck toward the left side of the frame to free the deck from the right side. The deck will move down once the frame has been cleared.
  12. Remove the deck and belt by raising the right side edge of the deck over the frame rail and sliding it to the right to remove.
  13. When installing a new belt or deck it is important to note that a new belt and deck surface should always be installed together. Failure to adhere to this guideline will severely shorten the life of the newly installed parts. Some decks can be used on both sides. However, be sure that each side is only used once. Be sure to install the belt in the proper direction on the unit.
  14. Install the belt and deck by first putting the belt on the deck, and then installing them from the right side as a unit.
  15. Be sure the deck is lined up with the frame and push the deck to the left side.
  16. Now carefully lower the right side of the deck to insert it into the frame rail and then push the deck to the right as far as possible.
  17. Re-install deck mounting hardware. (Check with mfr. for proper torque during install process.)
  18. Carefully place the front roller on the deck under the belt and push it forward into place, while placing the drive belt on the inside of the drive pulley.
  19. Replace the front roller bolts. (Check with mfr. for proper torque during install process.)
  20. Now spin the roller by hand while pushing the drive belt onto the pulley. Be sure to spin the roller several times to insure complete installation of the drive belt on the pulley.
  21. Install the rear roller into unit. Carefully start each bolt and turn one to two threads to ensure no cross-threading has occurred.
  22. Tighten each rear roller bolt the number of turns you kept earlier for reference.
  23. Now, Plug in and power on the unit.
  24. Carefully remove the bungee cord from the shroud and lower it back into place.
  25. Start the unit at a very slow speed and check for proper belt alignment. Remember to start at the slowest speed possible and be ready to stop the unit quickly if needed.
  26. If the belt is moving to right side of unit tighten the right roller bolt, If the belt is moving to the left side of the unit tighten the left roller bolt until the belt is tracking properly.
  27. Caution: make very small adjustments such as 1/4 turns and then watch the belt for several moments before making another adjustment.
  28. Once the belt is tracking properly walk on the unit at a slow speed and check for belt slippage on foot fall. If this is happening tighten each of the rear roller bolts equal turns until the slippage is no longer occurring. Caution: make very small adjustments such as ¼ turns and then watch the belt for several moments before making another adjustment.
  29. Now use the unit at a jogging speed to check for belt travel or slippage.
  30. If slippage still occurs make small equal adjustments (1/4 turns) to both sides of rear roller and re-test.
  31. Install the finger guards once you have enough clearance from the rear roller.
  32. Some manufacturers require wax or lube during the install process, please consult your owner's or service manual for further information regarding this.

What lubricant can be used on the Horizon T92 Treadmill


Go to www.horizonfitness.com then click on e-store then look for part and accessories the silicon lubricant to purchase. Follow this procedure before applying lubricant.
1. Inspect belt and deck. The deck should be smooth. The belt should have a consistent feel from side to side (a belt can be worn out without any sensory signs of a problem). If you feel deep grooves in the deck or uneven wear on the underside of the belt, part replacement is necessary. Continued use of your treadmill may damage expensive electrical components.
2. To inspect the belt and deck visually or to clean underneath the belt before applying lubricant, the belt must have the tension reduced. Loosen the tension roller by following the instructions in your owner’s manual. Do not loosen the bolts in the tension roller too far or the bolts will come out of the roller shaft. This step may not be necessary for your treadmill model or belt and deck condition.
3. Contaminants are the worst enemy of your belt and deck. Some treadmills may have an excessive accumulation of dirt and contaminants. If these are trapped during the belt lube process, significant damage will occur. If contaminant removal is necessary, loosen the belt by following step 2, lay the treadmill on its’ side, and use a nylon brush to loosen contaminants that have accumulated on the inside of the belt. Clean the deck with mineral spirits in a well-ventilated area. Allow the deck to dry before lubing or tightening the belt.

I need to replace the walking belt on a ProForm PFTL40070.


Installing An Icon Fitness Treadmill Belt You can save yourself a great deal of time by following these instructions as opposed to those of the manufacturer. Please contact us if you need any further help. UNPLUG THE TREADMILL BEFORE DOING ANY REPAIR!
Step #1- Remove the plastic railing on the right hand side of the deck. Most railings are stapled down so using a flat head screwdriver or another prying device is the easiest way to do it. The plastic is refastened using screws provided with the belt in a later step. If you cannot see the staples, you may need to remove the cosmetic center insert cover first by simply sliding it to the back of the treadmill. This rail is on the opposite side of the front roller pulley and motor. Some of the models aren’t stapled down and with these, you simply remove the rear end cap and slide the rail off the back of the treadmill.
Step #2- Loosen the rear roller and remove the two adjustment bolts. Some models have a spring loaded tensioner on the right hand side so be careful when removing these bolts. After the bolts have been removed, remove the rear roller end cap(s). The rear roller should now simply slide out of the walking belt.
Step #3- Remove the motor hood. Using a black permanent marker, make a mark on the front roller adjustment bolt on the motor compartment side at exactly where it fits flush with the roller so you will know where to retighten it later. The adjustment bolt is on the right hand side of the front roller. Then remove the bolt with a 7/16” wrench. Step #4- Remove the deck screws which should now be exposed since the plastic cover is off. In this step, also remove the staples with a pair of pliers. Be sure to remove all deck and staple debris before continuing.
Step #5- This step is easiest if you have another person to help but it is possible with one person. Lift up the side of the deck that has been loosened and making sure that the front roller is angled toward the deck, remove the old belt by simply pulling it to the side. A few models had a side hand rail that attaches to the side of the treadmill and if you have one of these, the hand rail must be removed first.
Step #6- Install the new belt just like you removed the old belt. Before proceeding, make sure that the belt is in the center of the two metal belt guides that protrude from the bottom of the deck. The guides should be angled where the sides of the belt are turned slightly upward. Sometimes these can get bent during installation so make sure they are contacting the edges of the belt or the belt will not stay centered properly. Step #7- Install the front roller adjustment bolt where you just start it. Do not return it to its original position yet.
Step #8- Install the deck screws.
Step #9- Slide the rear roller back into position and insert the end caps and rear roller bolts. Most models have a small ground wire on one of the rear roller bolts. Make sure to just slide this over the bolt before it is inserted in the roller. The ground wire dissipates static electricity that is built up on the walking belt to help the roller bearings last longer and reduce static discharge on the electronics.
Step #10- Adjust the front roller bolt to its original position.
Step #11- Tighten the rear roller bolts to where the tension on both sides feels even and you can lift the walking belt 2-3” in the center of the belt from the deck surface.
Step #12- Replace the right side railing with the screws provided using a screwdriver.
Step #13- Start the treadmill and align the belt according to the instructions in the owner’s manual or on our web site troubleshooting page under “Belt Centering Tensioning Instructions.”
Step #14- Once the belt is aligned, test the belt for slippage. If the belt slips at all, tighten the rear roller adjustment bolts equally on both sides ½ turn until the slippage is gone. Do not over tighten the belt where it has less than 2” of lift from the deck surface.
Step #15- Replace the motor hood and make sure no odd noise is apparent and that the belt is tracking and tensioned properly.

How do you replace the walking platform on the Nordic Track A2250 Treadmill?


First, remove the motor hood. There are 3 screws at the front, and 2 underneath. The screws underneath will have to be removed by tipping the treadmill over, or pulling the console towards the rear of the machine.

Next, remove the side rails. This is a little tricky because of the cushion adjusters on each side of the deck. If you look underneath the deck, you will see that the adjusters are on rails that are attached to the platform. Remove all of the screws from the side rail and push it toward the rear of the machine while also moving the adjusters rearward. You'll have to kind of move them together until the adjuster slides off the rail. Do both sides.

Remove the rear roller, by loosening the bolts. Don't mess with the front roller unless you intend to replace the motor belt. You don't need to remove the front roller or the walking belt.

There are 4 bolts holding the deck to the frame. The rear ones go through the frame to a lock nut. The front bolts screw into the isolators. Remove them and the deck will come loose. You can slide it out from the walking belt.

Place the new deck next to the old, and start moving the parts over. Make sure the safety decal is on the bottom like the old deck. All of the holes are pre-drilled except for the belt guides. You'll have to measure for these. Now do everything in reverse to reassemble the machine. I'm also attaching instructions on how to adjust the belt.

Normal 0 false false false MicrosoftInternetExplorer4 st1\:*{behavior:url(#ieooui) } /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} First, ensure that it is the walking belt that is loose. There is a belt hidden under the hood that connects the front roller to the motor (motor/drive belt). Start the treadmill at 3 or so and carefully apply pressure to the walking belt until it slips/stops. Watch the front roller. If it continues to spin when the walking belt stops, it’s the walking belt. It the front roller stops with the walking belt, the motor belt is loose and needs adjusted or replaced.

To adjust the walking belt, locate 2 hex head bolts, one on either side of the deck on the very back of the machine. These bolts will be recessed inside the plastic covers. Your treadmill came with a tool for this, but if you can’t find it, a standard (not metric) allen wrench kit will work. It’s helpful to have a wrench in each bolt so that you can adjust them at the same time, but one will work.

The allen bolts thread directly through each side of the rear roller. As you tighten the bolts, it pulls the rear roller away from the front roller, tightening the walking belt. This also centers it; if you tighten one bolt, it pushes the belt towards the center of the walking deck away from the bolt you’re tightening. So if the belt is too far to the right, tighten the right bolt and it will move towards the center.

Place your wrenches in the roller bolts and turn the machine on to 3-4 miles an hour. Keep your fingers clear of the belt, it will eat them. This method is quick, because you can see the belt move as you tighten one side or the other. It takes a few seconds, but if you tighten the right bolt for instance, you will see the belt move to the left. If the belt is loose but centered, tighten each bolt ½ turn and then get on the machine and see if it slips. The user manual will tell you to pull it up a couple of inches to test the tightness, which is a relative method and doesn’t necessarily work. My wife can pull on the belt and get 2 inches, and I can probably get 3 or even 4 if I’m showing off. The best way to test it is to gradually tighten it until you can run on it without it slipping.

You should lube the belt a couple of times a year. You can get them from iconfitness.com

Good Luck!
