wingless' Hein Warner HW93657 4 Ton Hydraulic Floor Jack


Recommended Posts

About 30 years ago I purchased a used / rebuilt / old commercial Hein Warner hydraulic floor jack. 


This has been a dependable workhorse tool for me. This has been my go to jack for all my automotive service projects. I REALLY love the large, stable, heavy-duty frame.


My automotive work that requires the vehicle suspended in the air ALWAYS includes blocking two wheels, lifting the opposite end of the vehicle from a chassis member, then lowering the vehicle frame onto a pair of heavy duty jack stands on a stable surface. If required the process is repeated for the other vehicle end.


Recently I decided to retire / upgrade / sell my old Hein Warner and replace it with a new Hein Warner HW93657 4 ton floor jack. Other than the cost I am very happy with that decision.


The new and old are similar but different. The biggest difference is the method for using the handle to position the far end side-to-side. The tool is massively heavy so positioning the far end requires the large handle lever to lock from downward movement, so additional downward pushing raises the wheels near the saddle, permitting moving the handle left / right to move the saddle right / left. The old jack had a locking pin control near the tee handle, locking the lever in several positions.


The new tool doesn't have ANY lock and initially I was lost for how to effect that required positional movement. Instead the new tool has the expected tee handle knob that rotates to release or hold hydraulic pressure, but it also may be pulled to release a pin. The pin permits changing the pump arc position. The 90° pump arc, from the large handle pump lever vertical to that lever horizontal is segmented into three ranges. This permits using the large handle pump lever to arc to the bottom of one of the three ranges, then push down further to lift the wheels near the saddle for positioning.


It initially sounds confusing, but after using it several times it becomes very intuitive.


The tool has VERY smooth movement when raising or lowering. When going from hydraulic turned from the hold pressure stop position there is a "large" (less than one turn) dead zone before affecting the saddle height begins. It is super easy and very controlled to get the desired position / speed result.

Looks like a nice heavy duty Jack.  I have been looking for a jack for a while.  Not that I use it a ton but always nice to have it when I need it.  My wife had a flat about two ago and would have been so nice to just use a jack like this instead of the junk one that comes with the car.
