Our mechanical lubricator
is available in both single (ML4) and double (ML5) feed versions as well as right and left hand and now includes a fluid
level gauge. The above illustration is a right hand lubricator. Normal
locomotive installation would mount a right handed lubricator on the fireman’s side with oil discharge forward.
The maximum dimensions are 2.5"high by 2.5"long by 2.875" across the crank.. Both
lubricators use identical parts and are of the same size, the only difference being the single outlet on the ML4, which is
in the center of the case. All pawls, ratchet wheel, cams and rams are hardened steel. The
ram is packed with an o-ring, which is easily replaced if it should become worn. This lubricator is designed
for long hard use with large bearing surfaces and robust components. Spare parts are available.
The lubricator case base has four mounting holes for
attachment to any suitable surface. The lubricator can also be mounted to rails or brackets in the locomotive
frame by removing the lid bolts, which are brass (4-40) and replacing them with steel. The lubricator can
be used to pump any oil from 10 wt up through light steam oils. The pump discharge is through a union fitting
suitable for silver brazing to 1/8 copper tubing. Filling is through a 3/8 opening fill plug on the top
of the case.
should be mounted on a sturdy surface, which will stand the forces delivered to the lubricator when in use. The
pressure stroke of the actuation arm should be set up in such a way that the link to the valve motion or other actuating device
will be in tension during the pressure stroke. It does take some force to turn the lubricator because it
is generating pressure as well as working against the ram return springs.
Also available is the
CVL6, a small right angle check valve, threaded ¼-40 MTP for insertion into the steam line and set up for 1/8”
copper tubing. This valve maintains oil in the line after shutdown and prevents steam from entering the
lubricator if the discharge check fails.
