I had a seized King Pin on a vintage Tractor ,had got it slightly out with a sledge hammer but it stuck fast in that position.Tried a screw type puller of reputable manufacture & it broke the foot off the puller leg.I ordered this Device without much hope but it worked easily & the adjustment for the leg length is excellent as the top yoke is on a long screw & can be progressively adjusted as the object gets pushed out which saves the need for spacers!Overall an Excellent Buy, would highly recommend & I'm a Time Served Mechanical Fitter who has worked on Railway Locomotives so have had much experience with such tools!
