Hi, Sisaytul07 and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Fuel line to carburetor or throttle body pinched or kinked.
8. Carburetor float stuck.
9. Fuel injectors clogged.
10. Severely discharged or damaged battery, you need 12.5 volts or better and be able to pass a load test if necessary.
11. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
12. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
13. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2, TPS, ETP, IAC,or BAS).
14. Faulty neutral, clutch lever, or kickstand safety switch.
15. Faulty fuel pump or fuse or relay.
16. Faulty CDI box if applicable.
17. Tilt sensor needs a reset.
18. Security system not disarming alarm needs a reset.

Where can i purchase just a replacement Lexel motor for a white mountain freezer?


Need to have an appliance tech look at it. Some motors have a current limit/thermal cutout inside. Does it cut off without being attached to bucket? Is motor gearbox bound up somehow? If motor is removed from gearbox and turns, then gearbox needs some lube or is otherwise defective/seized
The parts department charges $150 for this motor.

Pride Jazzy 1121 power wheelchair has leaked oil on the floor when stopped. It drags a little on the right side when I start moving. Anything I can do?


There's not too much you can do about the gearbox leaking oil. The gearbox will usually leak at the top gasket or seals. I suppose you could try to re-torque the bolts holding the top gearbox flange, but the other seals are usually leak due to age or overheating. If you pull it apart to re-torque the bolts, you might as well replace it along with the motor and brake. The gearbox grease stains are hard if not impossible to remove from carpeting and flooring.
If the motor drags you could have a bad brake which indicates you should replace the entire assembly. If the chair veers to the right you might have one motor spinning faster than the other due to age or damage. You can go into the programming menu with a hand held programmer and adjust the steering correct to compensate for the motor difference.
The bottom line is that you are due to replace at least one brake/motor/gearbox very soon. I usually replace them as a pair since the other side will also need replacement soon.
The motor/brake/gearbox assembly will run you about $700 for each side. Labor cost will be about 1 to 1.5 hour per side.
This is an older model Jazzy which was very sturdy, reliable and popular. You should evaluate the condition of the other components when deciding how much to spend on the repair. Replacement for a comparable chair has gone up considerably and I personally don't think the motor quality is as good. Hope this helps.

Noisy spin cycle


If the machine has been overloaded you may have partially damaged the coupling between the motor and the gearbox.or you may have damaged the gearbox itself...The coupling is a simple job for a tech but the other problem can be more expensive. Fortunately changing a gearbox does not take a long time. Check with a tech....Good luck....Nomess

Kenmore 70 series won't spin


If the washer makes a noise from the front bottom center, when not agitating and not spinning, the motor/gearbox coupling has broken.
closed2a0a669.jpg open7976f3d.jpg It is designed to break, if the load gets enough that the motor may be damaged and is simple (enough) to replace

whirlpoool 285753, parts common to whirlpool roper ge kenmore and about a dozen other brands.
dissassembly instructions vary slightly between models but close enough, some have 2 clips some 3
  • remove trims from ends of control panel 14db4bb.jpg
  • remove screws under trims
  • raise control panel and flip it over backwards
    (note: do not dislodge air tube from level selector)
  • remove brass retainer clips at rear corners
    (note: position for reinstall)
  • remove lid switch connector
  • remove lid and body
the motor and gearbox are now exposed
  • undo bolt(s) holding spring clips to pump,
  • remove spring clips holding pump to motor(note position for reinstall)
  • unto bolt(s) holding spring clips to motor
  • remove spring clips holding motor to gearbox
    (note position for reinstall)
  • there will be a plastic 3 legged 'spider' on the gearbox, and one on the motor, and a rubber ring with 6 holes that match the positions of the legs
  • remove the ring and spiders
  • take the ring and spiders to the local parts guy and get replacement,
    (Note the local parts guy will have the replacement, it is common to ge, whirlpool, roper, kenmore, new maytag, frigidaire and many others.)
  • use a piece of dowel, to hammer the center of the spider to the input shaft of the gearbox and the motor shaft,
    (note dont hit the legs they break.)
    (note: new spiders have metal center hubs, this is a common failure and the replacements have been strengthened)
  • turn gearbox shaft 1 leg up 2 legs down
  • turn motor shaft 2 legs up 1 leg down
  • insert new rubber ring over gearbox spider
  • insert motor into rubber ring
reinstall springclips
pump
pump springclips
body
control panel
in reverse order to above

gearbox coupling ~$17.00
time ~25 minutes, but I do 3-4/month

Top starts to go down then stops.


There is no gearbox. A motor runs a pump which moves the cylinders. You are probably low on fluid.
Behind the rear seat is your motor/pump/reservoir combination.
With the top down, fill the reservoir to overflowing with ATF.
Cycle the system a few times and repeat.
Do this till the reservoir will take no more fluid.
Check the lines and cylinders for leaks. The fluid must be going somewhere.
If you replace any lines or cylinders, always do them in pairs.

Kenmore 90 series washing machine


there is a coupling between the gearbox and the motor, it is broken, it is easy to replace, and inexpensive
the coupler can be purchased at a local parts store
'Kenmore motor/gearbox coupler' will get it for you, there is only on for all the models.
it is an easy fix
  • unplug washer
  • remove trim ends of control panel
  • remove phillips head screws from bottoms of control panel under where trim was
  • slide control panel forweard & up about 1 inch, then flip over the back of the control panel, do not dislodge the air hose
  • remove brass clips in rear corners of top with screwdriver, remember how they fit
  • unplug lid switch connector
  • lift body 1inch and slide forward to remove
  1. front center is the motor pump and gearbox
  2. do NOT disconnect hoses
  • remove spring clips holding pump on to motor shaft, note where they go for reinstall. there may be a lock screw in the top right clip.
  • swing pump to the left and use a string or bread bag tie to hold it out of the way.
  • remove spring clips holding motor to gearbox shaft, note where they go for reinstall. there may be a lock screw in the top right clip.
  • heave motor forward, to separate the coupling
  • remove coupling halves from gearbox shaft and motor shaft and discard.
  • using a wooden dowel and hammer, on the center of the new coupling halves, drive them onto the motor and gearbox shafts, (dont hit the fingers, they break, note the new couplings have metal centres to solve ongoing problems.)
  • rotate gearbox coupling, 1 up 2 down
  • rotate motor coupling, 2 up 1 down
  • install rubber shock pad on gearbox coupling
  • install motor on shock pad
  • reinstall spring clips and lock screw if fitted (bottom first, rock the motor on rubber shock mount to ease spring clip installation)
  • rotate motor shaft to align with pump input
  • install pump on motor shaft
  • install spring clips and lock screw if fitted
reinstall body in reverse order

it takes less time to do the repair than it takes to type this
