Decks And Vfx; Drive Belts - Landice L Series Diagnostic And Service Manual

Decks and VFX - Decks are solid pieces of wood with a phenolic coating that rest on the VFX
cushioning system.
1. The deck can make a squeaking noise when the VFX hardware is not properly tightened or
lubricated. You can test for this by bouncing on the deck when the machine is not running.
2. Sometimes the deck will need to be lubricated on the sides that go into the frame rails. Use
Lubriplate grease sparingly.
3. If a part on the VFX system is broken the deck will make a clunky noise when it bounces
against the damaged part.
4. A deck can also make a scraping noise when it is worn out.
Drive Belts- Drive belts make a high pitched squeal when they are worn or improperly tensioned.
It can also happen when the drive pulley and Drive roller are mis-aligned.
Elevation Motor- Elevation Motors consist of an electric motor and screw shaft.
1. Elevation Motor makes a crunchy noise when the main screw gear is dirty or corroded.
2. It may make a grinding noise if the gearbox is damaged.
3. Always check that the motor itself is not damaged and making noises because of broken
mounts, etc.
Drive Motor- The Drive Motor is an electric motor with a flywheel and pulley attached. The only
serviceable parts are the Drive Motor Brushes.
1. Drive Motors can make a clicking noise if the bearings in the motor shaft are no longer round.
2. Grinding noise if the bearings are shot.
3. Thumping, clunky noise if the drive shaft is bent or broken.
4. Tinny or clicking sound if the fan is rubbing against the fan cover.
5. Metallic grinding noise if the motor brushes are very worn.
6. Buzzing noise if the brushes are hung up in the brush holder.
7. Whining noise from bearings or internal problems.
8. Humming noises could be a faulty Capacitor, Choke Filter, or lower board affecting motor.
Visual Clues-
To paraphrase Yogi Berra, sometimes you can see a lot just by looking. The following is a
breakdown of things to look for when troubleshooting these components.
Decks- Check for wood showing through black phenolic. Check for ridges or cupping of deck
especially in front middle of deck. Both of these indicate that deck should be replaced or reversed
if other side is unused.
