Axles

·         Axle length is measured from tip to tip of bare Axle

Specifications

39mm Round Axles   -    750kg per Axle rating. Runs LM (Holden) bearings

40mm Square Axles  -    1000kg per Axle rating. Runs LM (Holden) bearings

45mm Square Axles  -    1400kg per Axle rating. Runs SL (Ford) bearings

TO WORK OUT YOUR AXLE LENGTH - WE NEED THE FOLLOWING MEASUREMENTS:

OR

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.

LM (Holden bearings) suit 39mm Round & 40 mm Square Axles

·         Outer (small) bearings   # LM 11910 - Cup

                                                # LM  11949 - Cone

·         Inner (large) bearings    # LM  67010 - Cup

                                                # LM  67048 - Cone

SL "Slimline" (Ford bearings) suit 45mm Square Axles

·         Outer (small) bearings   # L 68149 - Cup

                                                # L 68110 - Cone

·         Inner (large) bearings    # L 12749 - Cup

                                               # L 12710 - Cone

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:

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

Mini                                           -   7/16" UNF studs   -   4 Studs   -   PCD 101.6mm   -   5 1/2" hub   -   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.
