top cut off
5x5x.5 aluminum with 4.00 hole to weld in top

 Bulkhead fitting with o ring for the pump discharge

          lid seals with o ring

Powermaster booster pump repair

Replace vanes, rotor and cam ring. This pump would run but made no pressure
pump parts come out the end after ring is removed
         Drilled a hole to get at an end of the wire ring
        wear plates, cam ring, and outlet only fit one way as they are keyed or pinned
       Vanes had worn enough that one got out and no pumping happened.
          going back together

Sometimes the wire snap ring can be reused, We used a snap ring on this one with some machine work

Trigger wheel for LS going in Dakota. Tach drive

            Eight space trigger for Dakota tach signal going on the harmonic balancer
 This eight space trigger wheel is used by Dodge on their 5.9's. GM did not do this.
                Plug weld on to the balancer
            There was about .160" clearance from the seal to the balancer. Made the    wheel about .1" thick  for clearance.
                 Puller still fits if needed
          Starting to make the sensor mount, attached to accessory mount.
      Trimmed the Dakota sensor and bolted to new mount. Dakota ECM should be happy with an original sensor.
Wheel and sensor clear all the LS stuff
