Confession of a road builder

Confession of a Road Builder
Interesting breakdown.
Equipment: Caterpillar 633 Elevating Scraper
Location, Gold Coast Australia.
Weather Conditions,  Getting Hotter and very clear and sunny!
Problem, Hydraulic Pipe to front right suspension system worn out at P Clip after many years of vibration and is now leaking  high pressure hydraulic oil through a small pinhole rupture.
The pipe is not visible as it is located between the front wheel fender and the suspension cylinder,
with other pipes above and below it. Removing front fender (that has been welded in place) to access P Clip and remove pipe in the time frame allowed is not an option as it is Friday afternoon and already half past beer time!
The client also confesses that we are the third company they have called in to attempt repairs.
Simple Solution disconnect pipe from both ends, slide along P Clip until rupture is found and confirmed, cut through pipe at rupture with fine tooth hacksaw blade, Remove both pieces of pipe (one piece from each end) and prepare to replace pipe with high pressure flexible hose and crimp on fittings. Now we normaly stock female O Ring face crimp on fittings in our service vehicles but males are not so readily available or used, so ...... cut of male fitting from removed pipe, clean up and weld (silver solder) it into a crimp on hose fitting (called a lifesaver), manufacture hose assembly and carefully install using new O rings, top up hydraulic tank with oil and test. Pack up, clean up and beer time!

Urgent Repair Request
Equipment: Bomag Tandem Heavy Roller.
Location Gold Coast West.
Breakdown description:
Replace Rear Hydraulic Hose to Vibrator Motor
Original hose recently replaced by another company was found to be just a little too short resulting in the hose rubbing on an internal frame member and eventually wearing through the hose's steel braid reinforcing.
Solution: Crimp one end (Metric Fittings) onto hose, refit to machine and accurately measure and cut hose to length ensuring that there is a clearance air gap all around the hose. We also used a tough cover hose for even more abrasion and wear resistance. Top up hydraulic tank with oil and test.
Customer very happy with Quick Response Mobile Service.

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) .
