'One-Shot' to grease nipples

[GlennBurnage]

One-Shot to grease nipple conversion.
Before pumping Castrol Spherol semi-fluid grease with little added sae 140 (to thin it a bit) into the rack, I decided to try to assess any ‘stiffness’ this more viscous lubrication might produce. I looped a loop of string around a spoke of the steering wheel and attached an expansion spring to it. I pulled the spring until the wheel turned and noted how much the spring had stretched. Before I changed the lubrication, the spring stretched to 110mm before the wheel moved. I repeated this several times and got the same result each time – 110mm. I then took all of the One-shot system out of the car and let any oil drain from all the connections. After adding the grease nipples and the s/fluid & 140 mix I repeated the wheel movement test. Every time I repeated the test, the wheel moved when the spring stretched to 75mm. So much for making it stiffer, though I can understand the reasoning.
