Newgren
Lift
While the Monroe
system is the more well know lift, the Newgren Equipment Company lift
was also available through Willys dealers. We were searching for a more
common Monroe hitch, when we found a Newgren lift on e-bay. What
we really purchased was "part" of a lift. We picked
up a frame, ram (hydraulic cylinder), reservoir and control valve.
We were missing the hydraulic pump and the implement lift arms.
Hunk
o' rust
We
know little history of our lift. We picked it up in northern Ohio
and were told that it had been taken off a 2a parts jeep.
From the rusted body piece still bolted to the front control rod (visible
in the picture), we do know it was a red jeep. A PTO gear box
was still attached to the frame. It was missing the rear shaft
flange. It was not part of the original lift and would have been
part of the original jeep's PTO package. We do believe it is an early
model The reservoir and control rods vary only slightly from the
1947 instruction manual we obtained from fellow Newgren owner Daron
W.
The first
task was to take the components off the frame. This was straight
forward, since the ram is held by a single pin and the reservoir is
held on by a single strap attached with two screws. Once the ram
was removed, it was clear that a complete rebuild was in order.
We took the ram to a local hydraulics shop. Once we explained
what we were restoring, they suggested that they restore the ram, instead
of trying to substitute a new one. $350 later, we have a beautiful,
like new ram.
The frame had a broken
lift arm and we took it to a local welding shop for repairs. They
cut the short arm from the shaft and reattached it with a stronger weld.
The frame is a fairly simple form and was in good shape, except for
surface rust.
The reservoir
needed only a good wire brushing and cleaning. This was followed by
a quick coat of paint for the frame and reservoir. In the bottom view,
you can see the key components. The reservoir, attached to the
frame by a short strap and two screws. The rear control rod is
clearly visible, the hooked end is attached to the control valve. The
ram is in the extended position. The reservoir drain plug is visible,
and the pump return line fitting is shown at the top right corner of
the picture.
Like a glove
Mounting of the frame
is straight forward once you have rerouted the exhaust, and removed
the drawbar. The frame mounts under the bed, using the same mounting
holes as the drawbar. Pictured is the assembled frame, ready to
roll under the jeep. We had the frame on an old mechanic's creeper
and used bottle jacks to position the lift into place. Pictured
is a top view of the lift. One hose goes from the control valve
to the ram. The second hose goes from the bleed-down fitting on
the ram to the reservoir. The pump pressure side hose attaches
to the fitting on top of the valve. The connections on the top
of the reservoir are difficult to reach, once the lift is installed.
The shiny pipe extending from the rear of the reservoir is the filler
tube.
The lift frame
was engineered to fit like a glove and it does. The rear lift
frame member attaches with two bolts and uses the holes in the frame
cross member formerly occupied by the drawbar braces. As can be
seen in the picture, the rear of the lift bolts directly to the rear
frame cross member. The lift frame is a simple bolt on application.
The rear control
lever (the other lever is located next to driver's seat) is visible,
just to the right of the hitch. This is one of the best attributes
of the Newgren design, being able to adjust the height of the
arms while attaching implements is a must. Even on our Ford tractor
you have to move from the back of the tractor to adjust the implement
arms, the Newgren design makes attaching implements a one man operation.
Having the "dual" control set up was a real plus, that unfortunately
is lost when the reservoir and control valve are moved forward.
The only control lever is then moved to the dash or by the drivers seat
(as in the Monroe setup).
Plumbing
We continue to search
for an original crank-pulley mounted pump. Later models
appear to have used fan belt driven or electric pumps. These pumps
may have incorporated the reservoir and control valve as a single unit.
We have pictures of later model Newgren lifts that do not have the in-frame
reservoir and control valve. The Monarch pump commonly used for
snow plows has also been used to power the lift. We are using
a compromise solution of a 12 volt electric pump, that has its own reservoir,
but not a control valve.
We mounted
the pump along the passenger side frame rail, underneath the air cleaner.
The air cleaner is visible on the left edge of the picture. Hoses,
following the installation instructions, are routed along the inside
of the frame, to protect them to the extend possible.
This is not
an ideal setup. The multiple reservoir arrangement has made bleeding
the system problematic. We continue to search for a better pump
solution.
Arming
Major
missing components were the implement lift arms and the linkage parts
to the short lift arms. The good news is that the arms are simple
metal bars. We have drawings from the instructions and pictures
of other lifts that show the design. What we haven't been able
to obtain are actual dimensions. We attempted to use the drawings
to calculate the dimensions and built wooden prototypes. Shown
is a picture we received of a complete frame and a test fit with a mower
of our wooden models.
Once we were confident
that the length would work, we took the wooden model to our welding shop
and had a set of arms made.
You will notice that our "linkage" is an "L" bracket
attached to a "U" bracket by a bolt to allow some adjustment.
In operation,
we actually flipped the "L" bracket (the leg extends from the
top of the short arm), to increase the height of the implement lift.
All the bolts are grade 8 and should handle any loads we might apply.
It
works!
Shown
are a couple of implements - a "carry-all" and a 2-14 plow
(this is not the appropriate plow, but good for showing the concept).
We expect to move the
lift to the 3a we are restoring. As stated, we continue to search
for a better pump solution. We also will continue to research the
arms and linkages. But we do like many aspects of the Newgren design.
