Belt adjustment how do you get the cover off to check the motor belt

remove motor hood cover and check the belt drive. you might have to adjust the rear rollers to tighten the motor belt

Drive belt may not have adequate tension, motor brushes may be worn out, tread tension may be too tight, one or more of the control devices may have failed, the power to the treadmill is inadequate.

Drive belt can be viewed with the motor cover removed. If it slips, adjust tension until static belt delfection is about 1/8 inch.

If motor halts with load and belt does not slip, adjust the tread tension by turning the track tension bolts counter clockwise 1/4 turn at a time, both adjusters evenly. If no improvement 1 full turn in, check motor and or control board.

if tread adjustment does not help, check the brushes to make sure they are not hanging up in the holder. Remove the plastic caps that retain the brush inthe motor with treadmill unplugged, If they are 1/4 inch in length or shorter- replace brushes. If the motor does not have brushes, it is an AC type motor.

If brushes are fine, check motor voltage with an analog voltmeter- AC range if you have the open frame AC type of motor where you can see the windings (no brushes) and measure voltage on theboard terminals that go to motor. They should adjust from zero to at least 80 volts via the speed control knob. If the AC motor hums a great deal, replace the motor run capacitor.

If you have the DC motor, (usually about the size of a 1 liter bottle.), Check voltage range, it should have the same voltage range as above with meter set to DC range.

If in either case the motor moves fine, but full speed on control does not yield full motor speed, check the devices, usually SCR or Triacs on the AC motor type and MOSFETS or IGBT on the DC motor types.

Check that the belt has not broken or come off the motor pulley. Remove the top cover by removing the screws at the back of the machine and sliding the cover off forwards. Now you need to obtain access to the complete circumference of the drum to fit the belt. Depending on your machine you can either remove the front of the dryer, or release the rear bearing support so that you can slide the new belt over the drum and under the bearing retainer, which may entail removing the back cover as well. The belt then just slips over the motor pulley and you need to check on the belt tension, usually done by adjusting the motor or the tensioner. Good luck and please rate this solution.

All Mitsubishi cars pretty much hide the water pump under the timing belt. You should buy all new belts for the car and if you have 150,000+ miles consider replacing the water pump at the same time.
You will have to take off the power steering belt . First , take off the negative battery cable so you do not blow an expensive fuse on the positive battery cable clamp. Facing the back of the car , reach UNDER the alternator and loosen the bolt on the bottom right side, now loosen the bolt on the adjuster block on top, you can now turn the adjuster bolt and move the alternator to change the belt.
To take off the steering pump belt on the front of the motor, you need to loosen the nut on the back side of the pulley it holds the adjuster pulley in place . With the adjuster pulley loose , you can use the adjuster bolt to move the pulley to adjust the steering pump belt.
Now take off the upper belt cover, support the motor, take off the motor mount, jack up the right front corner of the car, take off the front right tire, take off the engine plastic under cover.
Line up the TDC timing mark on the cover to the mark on the pulley, check that the dot on the cam lines up with the timing arrow on the head, take off the lower pulleys, take off the lower engine cover, observe the timing marks/arrows and highlight with paint (crank marks and cam marks should all line up if not , put the lower cover and pulley back on and rotate the crankshaft one full turn.), loosen the timing belt tensioner pulley ,take off the timing belt, counter balancer belt if there is one. Now you can unbolt the water pump, scrape the gasket, and replace it.
The good news is, if you have tools,a compressor, an air gun (for lower pulley bolt), patience , and four to eight hours to kill, you can actually save money and do it your self.

Adjust walking belt tension at the front of the unit using the provided hex wrench on the exposed adjustment bolts located on each side of each front roller. Be sure to adjust both bolts on each roller the same amount as to not disrupt belt alignment. Tighten (turn clockwise) each adjustment bolt in full turn increments. After each adjustment, restart unit and check to see if belt slippage has been eliminated. Repeat if necessary.If slipping feel persists after several adjustments, stop and see if it maybe the drive belt. Remove left rear plastic cover to expose “v” belt drive line and motor. Tighten nut on the motor tension bolt located on front side of motor in 1/2 turn increments until drive belt slippage is eliminated - DO NOT OVER TIGHTEN. Replace cover when finished.

Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.

1. Loosen the alternator retaining bolts and remove the drive belt from the pulleys. Remove the water pump pulley.
2. Loosen and position the power steering pump mounting bracket and position it aside.
3. Remove the four timing belt outer cover retaining bolts and remove the cover. Remove the crankshaft pulley and belt guide.
4. Loosen the belt tensioner pulley assembly, then position a camshaft belt adjuster tool (T74P-6254-A or equivalent) on the tension spring rollpin and retract the belt tensioner away from the timing belt. Tighten the adjustment bolt to lock the tensioner in the retracted position.
5. Remove the timing belt.

To install:

1. Install the new belt over the crankshaft sprocket and then counterclockwise over the auxiliary and camshaft sprockets, making sure the lugs on the belt properly engage the sprocket teeth on the pulleys. Be careful not to rotate the pulleys when installing the belt.
2. Release the timing belt tensioner pulley, allowing the tensioner to take up the belt slack. If the spring does not have enough tension to move the roller against the belt (belt hangs loose), it might be necessary to manually push the roller against the belt and tighten the bolt.

The spring cannot be used to set belt tension; a wrench must be used on the tensioner assembly.

1. Rotate the crankshaft two complete turns by hand (in the normal direction of rotation) to remove the slack from the belt, then tighten the tensioner adjustment and pivot bolts to specifications. Refer to the necessary illustrations. Make sure the belt is seated properly on the pulleys and that the timing marks are still in alignment when No. 1 cylinder is again at TDC/compression.
2. Install the crankshaft pulley and belt guide.
3. Install the timing belt cover.
4. Install the water pump pulley and fan blades. Install upper radiator hose if necessary. Refill the cooling system.
5. Position the alternator and drive belts, then adjust and tighten it to specifications.
6. Start the engine and check the ignition timing. Adjust the timing, if necessary.

well that is very nice idea you can fix with your self provide talls most commonly use.Set of screw driver,open and socket wrench,pliers etc...Remove the top cover plate by loosening bolt holding the cover and cover besides the handwheel where the motor was installed besure it was unplug from ac source(No power)Check the motor holder that attaching from casing.You can see the motor coupled by the belt.In the motor holder there is a bolt slot adjustment for tensioning belt tighning and loosening.If you want to disconnect the belt and replaced loosen the tension and pull out the belt.Sometime belt are sliping to the pulley it affect
the sewing machine operation,you can tighten from adjusting the tension of the belt.adjust not so tight after adjusting try to run manually first by turning handwheel freely if the motor will run freely with out obtruction no power supply.If your satiesfied try to run with power supply but jag twice first to be sure no problem occured before continous operation.

Hi,
By removing the top cover, or the turning wheel cover,
you will be able to see the belt.
If the belt is not broken, then try to adjust the belt tension,
by adjusting either the height of the motor, or the tension wheel.
