Yamaha royal star motorcycle cluch whine and shudder in 4th and 5th gear at any speed


It is slipping. These big yamahas normally have slipping clutches. Mine slips, I've just learned to baby the clutch. Make sure you are in the most comfortable gear for the speed you are running at. Avoid rolling on full power at low speeds in higher gears. It's the nature of these great beasts. Clutch springs are too weak in these bikes, you may consider an aftermarket clutch spring assembly. The "shudder"(intermittent slipping) is caused by glazing. Make sure you are using the right lubricants for your bike, some synthetics can cause problems.

1)Adjust clutch cable correctly, check
2)Pull the clutch assembly apart, if there is little wear then you have "glazed" plates, clean each plate with 600 grit sandpaper and reassemble...get a new clutch spring assembly (weakened spring causes "shudder", slippage, and consequently glazing). Reassemble and adjust correctly (many forums out there with info).
3)Replace the full assembly and adjust correctly at setup. Adjust regularly....I check adjustment about every 300-500 miles.
4)Pay a shop to do these things for you.

When printing, the paper in the tray does not feed. It lifts but doesn't catch.


The printer's pickup roller needs to be cleaned or if its worned needs to be replaced. The pickup roller is the little blue rubber roller behind the cartridge. If it still doesn't catch you'll need to strip the machine down until you get to the springs that lifts the papertray. Stretch the springs a bit. This will cause the paper to be pressed against the pickup roller. Re-assemble the machine and try it.

THE ROLLER ON MY SHARK NAVIGATOR WILL NOT STAY ON, I CLEANED ALL THE HAIR FROM THE ROLLER AND IT STILL WONT STAY ON. IS THERE A BELT I NEED TO CHECK


We have only had our Navigator for 6 months and the bar won't turn. We took the whole beater bar head apart and it was a wiring problem in the beater bar motor.
What a piece of junk this is, very poorly made and has many design flaws.
Looking for something now to take it's place!

Need to check primary drive level on my FXDL 2003 as have developed slight leak from drain plug.Is it shared with engine oil?


No, the primary oil seperate from the engine oil. To check the level, you must remove the derby cover and stand the bike straight up. The level should be just to the bottom of the spring in the clutch assembly. Now, look at the clutch assembly and you'll see that most of the stuff is bright and shiney. Just inside the outer hub, you'll see a dark colored flat piece. This is the spring. It is a circular spring, not the conventional wound spring people think of when talking about a spring.

Good luck

The paper in my fax 575 always get jammed when receiving a fax.


Rubber rollers in the paper path probably have lost their grip; the surfaces become glazed and slip instead of transporting the sheet as they should.
Gaining access to the paper path varies in difficulty since many later units may be partly snapped together and use few screws for assembly.
If you decide to attempt this, use a hard cloth and naptha (lighter fluid) to scrub the rubber rollers; this should produce some black smears on the cloth if the rollers are glazed. Don't use alcohol since this will dry them out further. Naptha is safe for most plastics and aggressive enough to cut the glaze. While you are inside, check to make sure there are no scraps of paper complicating things.

My printer does not pick up the paper sheets from the paper tray.When I took paper sheet in to slot it works.


Well - I don't know if this will solve it (since there could be many causes) but it worked for me.

1 - Remove Paper Tray
2 - look at rubber rollers in printer undercarriage
3 - carefully remove "rubber bands" from roller
4 - turn rubber bands inside out and carefully return to rollers

5 - remove toner cartridge
6 - remove print drum assembly
7 - return printer drum assembly and toner cartridge

the roller trick helps the printer pick up paper
the toner/print drum trick helps reseat the inner workings of the printer correcting any misalignments that impede paper flow

The paper won't feed into a lexmark X3480


There are a pair of white rollers on a spring loaded assembly that feeds the paper into the machine. If these rollers are glazed or very worn, they will not feed the paper.

Also, the mechanism is known for its temperamental nature. I also recommend removing the paper tray and manually lifting the paper feed assembly gently by hand, insuring that it returns downward in a smooth and unobstructed manner. There are tiny clips that must be released on the white feed rollers, if you decide to remove them. However, I suggest giving them a good cleaning with a soft cloth moistened with dish cleaning detergent and water. Use very little detergent -- just a drop or so, and water. Wipe the feed rollers until the entire "tread" area is clean on both rollers.

Sony VCR


I'm not sure how old your unit is but over time, the rubber parts in a VCR become cracked, glazed and begin to slip.

There is a rubber wheel about the diameter of a nickel that is called the pincher wheel and does exactly what its called.

It pinches or compresses the tape against a shiny metal spindle called a capstan. The capstan spindle is connected to a motor. The pincher wheel rests against the turning capstan with the tape in between the wheel and capstan.

The pincher wheel can become glazed and coated with a brown oxide that has worn off of the tape. This causes the tape to slip and it can spool out into the VCR.

There is another wheel called an idler tire. It lays flat and pivots between the sending reel and pickup reel. Its used during play, fast forward & rewind. This wheel too can become glazed and worn causing slipping. If your unit won't play, fast forward or rewind, most likely the idler tire is the culprit.

There are also belts that can also become glazed and worn. These belts are used along with motors in the tape load/eject mechanism and capstan drive. If the belts slip, the tape may not load or eject properly and the capstan might not be turning properly.

When I owned my repair shop, one solution was we to remove the belts and/or tires and apply a re-grip solution on the rubber with a cotton swab, while roughly rubbing the the entire rubber surface back & forth with the swab. The re-grip solution actually eats away the top surface of the rubber leaving the rubber surface course and causing it to grip better.

Another solution was to just replace all of the rubber tires and belts. These parts including the re-grip solution may be ordered through www.mcmelectronics.com

Please let me know if I may be of further assistance to you.

Good luck!
