08/12/19 – Brake Overhauls continue

Another weekend and the brake overhauls for the van train continue.  Nick, Jake and I in attendance. First cylinders on B777728, B780282, and B777171 were prepared for removal.

Once the three were ready, we dropped B777728s cylinder.

This was promptly overhauled,  insides vacuumed, piston rod polished, seals replaced and the cylinder rebuilt.

The cylinder was then replaced under the vehicle and as the light failed B780282s was dropped.

The final task for Saturday was to reseal the joints on the through pipe of B850498

On to Sunday Nick, Ross and I in attendance B780282s cylinder was stripped, cleaned and overhauled internally and replaced under the vehicle.

As quick as B780282s was lifted B777171s was dropped and again split and overhauled.

This was also refitted and our attention turned to coaxing life back into the test rig. With the warmer weather and after a little persuasion the rig fired up and the vehicles worked on so far tested.

E87674, B786348, B763305, B777728, B780282, B777171 and the through pipe of B850498.

The through pipe of B850498 was improved but exceeded the minimum 4 inHg drop over 5 minutes. The South end hose of this vehicle has yet to be changed and this will be the next course of action.  B763305 held vacuum for 16 minutes, the only item not looked at for this cylinder was the release valve as this is a C type westing house vacuum cylinder which has a different design of piston and release valve,  we have yet to overhaul this type of valve so further investigation into this type is our next course of action. E87674 required an adjustment of the brakes which was carried out and once a number of applications of the brakes on the various wagons were carried out and the timers started.20191208_151559
