Hub Piloted - Cone Lock Nut Mounting (CLN)
One nut per stud tightens and holds both inner and
outer duals, or single wheels.  Only right hand nuts are
required.  Wheels for cone lock nut mounting are
identified by the lack of deep countersinks around the
stud holes. Wheels are centered by the close fit of the
wheel center hole to the hub pilot. Hub piloted wheel
systems are available in both 8 and 10 hole
configurations.
Outboard drums (Fig. 1) eliminate the need to remove
hubs when servicing brakes vs. Inboard (Fig. 2).
Stud Piloted - Double Cap Nut Mounting (DCN)
Inner and outer nuts on duals, or single cap nut on
front wheels locate and hold the wheels.  Both right
hand and left hand threaded studs are required.  A
total of 20 nuts required per wheel; 10 inner, 10 outer.
Wheels are identified by spherical countersink around
bolt holes.  Wheels are centered by the fitting of the
ball face of nuts into the ball seat of wheel bolt holes.
Inboard or outboard drums can be used.

Type of Slack Adjusters
Per Docket No. 91-21 Notice of the Federal Register, all air-braked vehicles requiring FMVSS-121 compliance built on or
after October 20, 1994 will need to be equipped with automatic slack adjusters and stroke-indicating air chambers.  Axles
are still available with manual slack adjusters, however these axles should only be used on 121-exempt vehicles. Ultimate
responsibility for compliance lies with the vehicle manufacturer or axle installer.
TRAILER AXLE KITS
Our Axle kits are covered by part numbers made up of codes . These codes represent various axle components.
These components are loose; however axles can be ordered with components assembled by simply adding an "A" to the
beginning  of the part number.   (Example: AS08-1309-2008-09)
Because of the wide selection of axles available from stock, orders for assembled axle kits can be filled on short notice.
Look over the listings on the following pages. If you need more information, call us.
We can help!
Using this guide, we will have a part number similar to
the example below, that we use to order your axle kit.
Part No. AS01-1209-0808-09
Do you want your axle components assembled? Yes / No  The example calls for an assembled axle.
Type of bearings?   The example calls for Timken bearings.
Axle?  In the example, the axle being used is part number 1014057. See the following pages listing axles.
Oil Seals?  Choose the seal of your choice, making sure it is compatible with the axle you are using.
The example is using Stemco.
Hubcaps? Make sure the hubcap you choose will work with the wheels that will be used.
The example is using two six hole aluminum hub caps.
Slack adjusters?  These should be compatible with the cams on your axle.
The example calls for R801074 Meritor auto slacks.
Air Chambers? The example here calls for an Anchorlok sealed type 3030 spring brake part number.
Cast Wheels or Hubs? Make sure it works with the axle being used.
The example calls for a set of ten-stud hub and drum assemblies with RH and LH studs (1013824 & 1013825).
ABS RULES
Because of government mandates, all trailers built after March of 1997 must be equipped with ABS.  On replacement axles,
care must be taken to equip the replacement axle to match existing systems.
