I noticed that both lift arms are keywayed. The lift shaft will have to be pulled out of the lift arm housing, repositioned, and slid back into the lift housing. Is this possible to do?

You can flip the lift arm end for end so that the lifting force is against the unworn side of the shaft. Dean [Reply]  [No Email]

DO get a manual or a video before pullingthe lift cover off as you can damage the backpressure valve if you snatcht he cover off without backing it off under the acorn nut. soundguy [Reply]  [No Email]

The center dogbone rocker arm and the outer lift arms all have a matching extra wide spline machined inside them. There is one and only one way you can put this assembly together. If your lift doesn't raise all the way up your cam follower pin is most likely worn. You will need to remove the lift cover and rebuild it. You can buy a video on Fleabay that shows the lift cover rebuild in detail. Hydraulic Video [Reply]  [No Email]
