Hose Fixing Marathon in continuous rain
We recently had a tough challege, to replace a blown track drive hose on a Caterpillar All Terrian Loader. The conditions were far from ideal with cool windy and very wet weather.

Mission, Remove, Manufacture and re-install blown high pressure track drive hose on Caterpillar 359B all terrain loader.
Location, Light Rail Project, Surfers Paradise, Gold Coast Australia.
Weather Conditions, Cool with Continuous Rain.
Environment, Very soft, very wet and gritty with sand.
Status, Very Urgent.
Client V.I.P!
Special tools required, Franer Crane and lifting slings. (Many thanks to the Guys at Gold Coast Cranes)
Method, ground to soft for jacks so had to lift entire machine onto jack stands supported by large steel plate. Slacken track tension, remove track motor drive sprocket and front idler wheel and then pull off entire track. Tilt back cab to access hose manifold. loosen nuts from manifold and track motor and remove from machine. Manufacture new 4000 PSI 4 wire hose on site, re-install hose (with new O rings) , then track, then motor sprocket, then idler wheel, tension track and tilt cab back into position. Top up tank with hydraulic oil and test.
Total mission time 7 hours (including wait time for crane) .
