Bearings

Bearings are used to match the type of axle you have NOT the type of stud pattern you have. Eg. If you have Ford wheels, but your axle is Holden, then you need hubs with a Ford stud pattern and Holden bearings.

·         Inner (large) bearings    # L 68110 - Cup

                                               # L 68149 - Bearing

The best way to work out what bearings you need is to measure the flat part of your axle stub where the bearings sit. Use these measurements to work out what you need:

Mechanical Brakes

Choice of 2 handbrakes....

              Boat Hand Brake                  Standard Handbrake

Boat trailer handbrake              OR              A-frame handbrake

 

 

BRAKE SETUP WITH BOAT TRAILER HANDBRAKE

 (we recommend you customise your own bar to suit your drawbar - as shown in red on the under-side of the drawbar)

 

OR

 

 

BRAKE SETUP WITH STANDARD A-FRAME HANDBRAKE

(Please note: this picture incorrectly shows the caliper mounting bracket mounted to the wrong side of the caliper. The caliper will only bolt on one way - where the mounting bracket is between the disc and the caliper. However, it still gives a good idea of how the system fits together)

Stud Patterns / PCD

(for all hubs / hubdrums / hubdiscs)

Stud patterns are worked out using the PCD measurement. This is the distance from one side of the stud circle to the other (see picture below). Many wheels from different makes and models have the same PCD, ie. even though a stud pattern is referred to as 'Ford', it also matches Mitsubishi, Mazda, Toyota etc.

 

Ford                                          -  1/2" UNF studs   -   5 Studs   -   PCD 114.3mm   -   68mm from stud to stud

Holden HT / Early Holden          -   7/16" UNF studs   -   5 Studs   -   PCD 108mm   -   65mm from stud to stud

Holden HQ                                -   7/16" UNF studs   -   5 Studs   -   PCD 120.6mm   -   72mm from stud to stud

Commodore                              -  7/16" UNF studs   -   5 Studs   -   PCD 120mm   -   72mm from stud to stud

Gemini                                      -   7/16" UNF studs   -   4 Studs   -   PCD 100mm   -   not available in braked kits

Toyota                                       -   7/16" UNF studs   -   4 Studs   -   PCD 114.3mm   -   not available in braked kits

Why use bearing buddies with your hubs?

Because water enters your grease & bearings under normal conditions, and without bearing buddies, air pockets are created within the hub, and get hot and expand.

As you drive down the boat ramp, the bearings enter the cold water. The air and grease inside the hubs shrinks and sucks in water.  The problem with this is that the water then contaminates the grease, turning it into a hard, gritty, muddy muck. This will DESTROY your bearings.

And no one wants to be stuck on the side of the road, in the middle of nowhere, wishing they had Bearing Buddies.

When using bearing buddies, drive to the boat ramp, pump grease into the bearing buddies until it expels grease out the rear seal. It is spring loaded so it keeps a positive pressure and is solid with grease inside your hub, which in turn helps to stop water entering.

Bearings will still need maintenance, but just not as often, the savings you get back from bearing buddies, in grease and labour, will pay for itself in one wheel bearing grease change.
