IMPORTANT: To properly operate and maintain your DIXON BAYCO hose swivel the

following instructions are provided. Please read with care as improper handling or
maintenance may cause a hazardous condition.

CAUTION: Do not modify your DIXON BAYCO hose swivel for any reason. It could

result in a hazardous condition due to operating difficulties or malfunction.

Disassembly or tampering will void the product warranty.

Installation: DIXON BAYCO hose swivels are properly adjusted, tested and ready to

use upon leaving the factory. When connecting the hose swivel to the hose or pipe

fitting, apply a thin layer of a suitable thread sealant (such as DIXON “LCTS 1”) to

the male threads on both the hose swivel and the connecting fitting. Tighten each end
snugly to ensure a leak proof connection. WARNING: DO NOT over-tighten during
installation. DO NOT use a pipe wrench, which can cause distortion of the body and
possible leakage. A spanner or crescent wrench is recommended. Tightening with a
pipe wrench WILL VOID WARRANTY.

Care & Handling: DIXON BAYCO hose swivels are tested at the factory and are in

proper working condition when shipped. Hose swivels are designed to be tough and to
provide long service with reasonable care and handling. However, never drag hose
swivels across rough surfaces as this may cause damage and malfunction. Immediately
remove from service any hose swivel that is not performing satisfactorily.

Inspect for Loose Set-Screws: Hose swivels can fail to perform properly if not

maintained. Occasionally check all three set-screws for tightness. If found to be loose,
retighten securely; take care not to strip the threads. If one or more set-screws is
missing, immediately replace with a new set-screw and lock washer. Please see back
page for available repair kits.

Lubrication:

DIXON BAYCO supplies each hose swivel already lubricated. However, should the
hose swivel become difficult to rotate it is recommended to re-lubricate. The hose
swivel can be lubricated without disassembly. HOWEVER, MAKE SURE THE
HOSE SWIVEL IS NOT UNDER PRESSURE. DAMAGE TO THE COMPONENTS
OR PERSONAL INJURY MAY OCCUR!

 Order repair kit SWMF-RK1.
 Remove one of the three set-screws (3) from the hose swivel with a 1/8” hex key.
 Insert the grease-fitting adapter into the screw hole; connect grease fitting to

adapter; be careful not to strip the threads inside the screw hole!

 Apply a lubricating product until it begins to emerge through the screw holes

(loosen one additional screw to ease emerging grease) or from the dust seal end. It
is highly recommended to use such a product as DuPont Krytox GPL-204 to ensure
superior cold temperature performance and longevity of the internal seals.

 Remove grease-fitting adapter; reinsert the set-screw (3) complete with lock washer

(4); tighten snug, but be careful not to strip the threads!

Inspection and Rebuild: The DIXON BAYCO hose swivel may be rebuilt while still

connected to the hose fittings. However, the hose line must be depressurized and
completely emptied prior to disassembly TO AVOID COMPONENT DAMAGE OR
PERSONAL INJURY!

 Remove all three set-screws (3) and lock washers (4); gently pull swivel housing

(1A/1B and 2A/2B) apart.

 Remove dust seal (13) and rear bearing (10); remove front bearing (9); remove o-

ring holder complete with o-ring seals (7, 11, 12); remove support washer (14).
At this point it may be decided to simply replace the main seals (7, 11, 12), the dust
seal (13) and the radial bearings (10, 9). If this is the case, use repair kit SWMF-RK2 /
SWMF-RK22. Then, skip the next two disassembly steps and proceed to the bottom
paragraph describing reassembly. However, if a complete rebuild is required
(including ball bearing [5, 6] and support ring [15]), use repair kit SWMF-RK3 /
SWMF-RK32 and proceed with the following instructions.

 Remove retaining ring (8) with proper removal pliers, be careful NOT TO

SCRATCH any sealing surfaces on the swivel inlet (2A/2B) when pulling off.

 Remove thrust washers (6) and thrust bearing (5); remove support ring (15).

Thoroughly wipe off the old grease from all removed components with a clean rag.
Visually examine all components. Remove any burrs and sharp edges that could
damage the seals during reassembly. Replace any damaged parts. Before assembly,
liberally apply lubricant (DuPont Krytox GPL-204 is recommended) to the inside
diameter of the swivel body (1A/1B), the outside diameter of the swivel inlet (2A/2B),
the o-ring holder complete with o-ring seals (7, 11, 12), and the thrust bearing (5).
Reinstall all components in reverse order as disassembly instructions.
