BEARINGS AND HUBS

Note: Check wheel bearings periodically by the following procedure:

CAUTION - Leave the trailer connected to the tow vehicle with brake set and wheels choked. (Trailer must be on level ground).

1. The first step in jacking up your trailer is to block the wheel on the opposite side, both front and back.
2. Position the jack on the frame as near to the wheel as possible.
3. Proceed to spin the wheel and listen for any noise. Feel the wheel for any roughness in its rotation. If your trailer is equipped with brakes, be certain that the brake shoes are not dragging.
4. A quiet and smooth rotation indicates that the bearings are in good shape. If a noise or grinding sound is evident, please contact your dealer for proper procedure.
5. At this time the wheel bearing adjustment should be checked. We have set the proper torque to maximize the bearing life but on occasion it may be necessary to make an adjustment.
   
   To check to see if an adjustment is needed, grip the edge of the wheel to see if it rocks, or can move. If the wheel moves at all, an adjustment is necessary.
   
   First remove the bearing protector or dust cap (refer to the section on bearing protectors in Section F) and the cotter pin. Tighten the spindle nut a little more than "finger tight" (approximately 20-24 inch pounds). When the nut is positioned properly the wheel should turn easily and have no end play.
   
   Reassemble the reverse of disassembling using a new cotter pin.
   
   Note: This bearing adjustment should be checked after the first 75 miles and about every year after that.
6. If needed, grease hubs carefully before launch or before storage. Do not add grease when hub is cold, too much grease will damage brake shoes and hub seal.

Smaller trailers are built with a steel dust cap and must be lubricated by repacking the hub by hand at the end of each season. Bearing protectors can also be added as an option.

Larger trailers are equipped with a patented lubrication system which incorporates an internally cored spindle and grease fitting. This allows the hubs to be easily greased without disassembly, and assures lubrication to the inner bearing. Using a high temperature grease (such as Shell Darina, or Drydene 4000) and a hand-operated grease gun, lubricate each wheel periodically or before a long trip with a few pumps.

NOTICE: It is highly recommended that once a year, each wheel be pulled, and the following items visually inspected and replaced if necessary: bearings, bearing races, seals and brake components, Repack with new grease and reassemble using a new cotter pin.

All work should be performed by a qualified mechanic.

NOTE- The drop type axles allow a visual check of the grease as it is purged from the rear of the spindle. Straight axles do not allow this visual check and therefore the dust cap must be removed if there is any question as to the quantity of grease in the hub.

To remove your bearing protector or dust cap, place a piece of wood against the side of it. Carefully strike the wood with a hammer. Then place the wood on the opposite side, and restrike. Continue this procedure until you have "walked" the protector out of the hub.

To reinstall your bearing protector or dust cap, line it up with your hub, place a block of wood over the front of the protector and carefully tap the wood with a hammer.

NOTE: All bearing protector caps are designed to fit tightly into the hub. Please take care in aligning the protector cap with the hub.

To determine the proper tire size, designed for your model, refer to your certification plate (located on the front left side of your trailer). This plate will also give you the proper tire rim that is needed.

The recommended air pressure can also be found on your certification plate and it will be found molded on the tire.

Should your certification plate be damaged, your marina dealer can help you in determining the proper tire and rim size.

When jacking up your trailer, to change tires, please follow the same procedure that you used in checking hub bearings.
