Teac x-1000r tape skewing off pinch roller


In the Teac X1000R this is most often caused by dirty Pinch Rollers and secondly bu a ring of oxide or a wear mark being developed into the capstan shaft. If cleaning the Pinch Rollers does not do it then a trip to the technician is required. These decks also have a touchy servo tension system that if upset can also contribute to the failure of this kind. I still work on these in Chicago area all the time. Russ the other ex-Teac guy is in New Jersey. Be careful of local shop with this model as many of them turn up the servo tension to resolve this problem which is the wrong thing to do that then burns out parts and the cost goes up. I have seen this mess many times as people bring me these decks as a last stop-- of course I fix then correctly with the use of the Tentelometer as is required. Pinch Rollers are often reconditioned with Naphtha after cleaning then with Denatured alcohol.

95T Treadmill Belt and Deck Replacement


Video Demonstration of a Belt and Deck Replacement on a Life Fitness 95 T Treadmill

  • This video demonstrates the steps necessary when performing a belt and deck replacement on a LifeFitness 95T treadmill
  • Tools Necessary:
    • 9/16" Socket Wrench or 9/16" Hand Wrench
    • Long Flathead Screwdriver
    • Phillips Screwdriver
    • 4MM Allen Wrench or Allen Socket
    • 8MM Allen Wrench
    • Plastic Putty Knife
    • Shop Vac or Vacuum
  • Begin by turning off power at the treadmill and unplugging the unit from the wall
  • Remove the upright tube caps from the inside of the uprights
  • Remove the Phillips screw and tilt the cap in at the top
  • Remove the motor shroud by first taking out all four screws in the shroud
  • Then remove the screws at the top of the front panel and loosen the lower screws
    • This will leave enough play to remove the shroud as shown in the video
  • Now with the Phillips screwdriver, remove the finger guards at the end of the treadmill from each side of the rear roller
  • You will need to slightly twist the finger guards to get them out from under the belt
  • Using the 8MM Allen Wrench, loosen the bolts on each side of the rear roller by 10 full turns
    • At this point, you can completely remove the rear roller bolts while keeping count of the number of turns at each side of the roller
  • Do not include the 10 full turns from the previous step, only count the turns for this step and make note of the number of turns for future referenc
  • Carefully remove the rear roller from the treadmill and set it aside
  • At the motor compartment, use the long flathead screwdriver to lift the tensioner arm and remove the drive belt from the drive motor pulley
    • CAUTION Pinch Point
  • Using the 9/16" socket wrench or hand wrench, remove the bolt from the front roller mount
  • Carefully remove the front roller from the frame and set the roller aside
  • Use the 4mm Allen wrench or socket to remove the 4 deck bolts from the deck
  • Once the 4 deck bolts are removed, you can pull the deck and belt from the frame
  • Be careful to not let the deck drop too far down into the frame during removal
  • Damage to the anti-static tinsel can occur if deck drops too low into the frame (as seen in the video)
  • It is recommended to thoroughly clean the treadmill before completing your belt and deck replacement
    • While the belt, deck and rollers are out of the frame is a great time for cleaning
    • Dirt, debris or other contamination can cause noise, early damage or premature wear on new parts
  • Use a plastic putty knife to scrape away any debris build up from the front and rear rollers
  • Vacuum most of the painted surfaces then wipe clean with a Sportsmith equipment wipe
  • Once you've completed the cleaning of your treadmill, it should now be ready for reassembly
  • It is necessary to install a new deck surface with the new treadmill belt
  • Your unit may have an unused side of the deck that can be flipped into use or the deck may need replaced
  • Before installing the new deck surface, inspect the tinnerman clips
    • The tinnerman clips are what the deck bolts thread into
  • Simplify the installation process by placing the new treadmill belt over the new deck surface
    • Ensuring the belt is installed in the proper direction
      • If marked, use the arrows on the inside of the belt
  • Now place the belt and deck into the treadmill as a unit
  • Install the front two deck bolts (closest to the front roller) about half way
  • Then use a long tool to line up the deck holes by the rear roller while placing your weight onto the deck to allow the bolts to start
    • Install these bolts in about half way
  • Now tighten all four deck bolts
  • Carefully insert the front roller under the treadmill belt and into place
    • Making sure to install the drive belt over the pulley on the front roller
  • Install the pulley end of the roller into the frame and align the other end with its bolt hole
  • Install the bolt and using the 9/16" socket or hand wrench, tighten it
  • Again, use the long flathead screwdriver to lift the tensioner arm and reinstall the drive belt onto the drive motor pulley
    • Practice CAUTION as this is a Pinch Point
  • Install the rear roller under the belt and while pulling back on the roller install the roller bolts on each side
  • Remember to keep count of the number of turns on the rear roller bolts
    • Reinstall the roller bolts using the same number of turns you noted from earlier
  • The belt may still be too lose, but that is ok as it can be fixed in a moment
  • Plug the unit back into the wall outlet and turn the power on
  • Start the unit at a very slow speed and observe the tracking of the belt
    • If the belt is not turning with the front roller, make small equal turns of the rear roller bolts until the belt begins to move
  • If the belt moves quickly to either side of the frame, quickly press the STOP key to keep the belt from being damaged
  • If the belt is moving to the left side of the unit, you can tighten the bolt on the left side of the rear roller
  • If the belt moves to the right side, you can tighten the bolt on the right side of the rear roller
  • Once the belt is tracking straight, move on to the next step
  • Re-install the finger guards over the rear roller with the Phillips screwdriver
  • With the unit stopped, step onto the treadmill and straddle the running belt with a foot placed on each side of the frame
  • Start the unit at a walking speed and begin to walk on the belt
    • If the belt stops on your foot fall or with your weight, make small adjustments such as 1/4 turns on each side of the rear roller until the belt slippage or hesitation is no longer felt
  • Continue this adjustment until no slippage or hesitation is felt at running speed
  • Now reinstall the motor shroud and upright tube caps
  • Log the repair into the Maintenance record of the treadmill display electronics
    • Press STOP then hold the PAUSE key until the display comes on and reads SERVICE MENU
    • Use the UP or DOWN arrow to scroll to MAINTENANCE and press ENTER
    • Display now reads MAINTENANCE MENU
    • Use the UP or DOWN arrow, scroll to REPLACING BELT/DECK and press ENTER
    • Display will read REPAIR LOGGED and will then return to the SERVICE MENU
    • You can press STOP key to exit the SERVICE MENU
  • This completes the belt and deck replacement on the LifeFitness 95T treadmill

Replace belt on teac x1000r


The belt being broken is just the tip of the iceberg. Yes, people change them themselves all the time then they bring the deck to me when this does not work. Besides the belt, the capstan motor has to be determined good or not- sometimes a sticky belt can burn up the motor a $150 part. Typically, pots need cleaning, Flywheels should be extracted and oiled as well as capstan shafts cleaned and reconditioned- the Flywheels are particular as how they go in. I get units in with them reversed and another problem is created. The adjustment of tension arms requires a Tentelometer and the voltage references have to be set- they are usually off due to mechanical changes to the tension arms. The the calibration of the deck should be done. Also people are buying a wide belt in E bay and it does not work- I end up taking it out and putting in a correct sized belt. Rollers and Pinch Rollers need oiling and the washers put in where missing and so on.
If you are in Chicago area look up skywave Tape Deck Repair on the internet- I work on X1000R and X2000Rs all the time.

Teac a-3440 will not play


Hi Gary,
This makes me think the Capstan Shaft is not turning either due to a broken or stretched belt or that the capstan motor itself has stopped working. This may be a job for a Technician. You first determine if the Capstan is turning or not- this is the metal post that contacts the Pinch Roller that rotates and is the way the deck gets it's speed regulation. If it is not turning look inside the deck from the side to see if the flywheel is turning and that the belt is on that flywheel. Lastly make sure the capstan motor is turning.
Beyond that a Tech may have to take over from there. I am in the Chicago area and can repair it if you are close. Many people send me units from all over the USA anyway.

My Nakamishi Cassette Deck 2 is eating tape. It switches off when it does, but how can I fix this? From the look of it this cassette deck has the same cassette drive as the DR-8. Is that correct?


It could be the take up spindle does not have enough torque causing the tape to bunch up after the capstan. If you open up the unit you will notice ether belts or rollers for the tape drive. If it has belts you can replace the belt after cleaning the pulleys. If it has rollers you may be able to clean them with a rubber cleaner (not alcohol which will dry the rubber and cause glazing). Make sure the capstan and the pinch roller is clean using a rubber revitalizing cleaner on the pinch roller. "Goof off" from a hardware store is great for the capstan if it has a lot of metal oxide on it.

The capstan drive roller on my tape deck fell apart. Spindle is .0975" dia. Pinch roller is .862" dia. All other belts and rollers seem OK. Where can I find a replacement capstan roller? Thanks.


You need to locate the supplier of pinch rollers that will fit your tape deck. If that fails, you have a useless piece of gear. If the unit is of decent quality, you should be able to locate a supplier. You didn't include the make or model, so good luck.

I purchased a Nakamichi 480 tape deck from a seller on eBay. All the push buttons work OK except for the EJECT button. It will not allow the compartment to open where you insert a tape. The eBay seller...


Hi there
It is probable that the head assembly or pinch roller assemblies are not returning to their correct rest position. The arms that carry the pinch roller assemblies develop dried grease problems in the bearing/post they are mounted to that prevent their timely return and fouling the casette shell preventing eject. Check them by seeing if they are clearing the cassette shell, and are "sprung into the home position with out binding.
I have repaired scores of these decks over the years, and am happy to talk to you more about the problem. Thanks for using FixYa.

You can get a FRESH belt kit from here. Cost you $10 plus some post. There is a new pinch roller listed against this old girl also could be worth replacing at the same time when you service the deck.

Need pinch roller support pins for the Dragon cassette deck


Hi davejann

These guys can certainly help you with parts for older Nakamichi decks. They are in the UK, and have most parts for pre 1996 tape decks from the legendary makers. The synthesis chassis had dramas with pinch rollers siezing up from dried grease. I always used to strip and relube, and often replace the pinch roller/tape guide assly. Hit them up, if you have any dramas, get back to me here.

I am more than happy to answer any other questions you may have about it, just give me a hoy :) Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.
