Hello all
I have just purchased another Cat D7 17A
She has not been running for 10 - 13 years but ran very well by all accounts Owners just lost interest in it
She has foot rot but all else is in tact and I just want to get it started so I can get her home for parts
A part from cleaning out the starting engine carburetor checking fluids clean out diesel filter and lines etc (bit of water in trany etc but will do till I get it home) what else should I be looking at before I try to start her
Any help always useful
Thanks all
LOOKS LIKE YOU HAVE A GRAND PROJECT. IM ASSUMING IT HAS THE PONY MOTOR AND IS DIRECT DRIVE WITH THE CABLE POWER UNIT? YES, LIKE YOU SAID, GET PONY MOTOR RUNNING OF COURSE( MAYBE CONVERT TO 24 VOLT ELECTRIC START LATER). CHECK AND CLEAN FUEL SYSTEM BY DRAINING ALL OLD FUEL. BLOW OUT FUEL LINES. CHANGE ALL FUEL FILTERS, CHANGE OUT THAT OLD OIL FILTER TOO. CHECK YOUR TURBOCHARGER TO ENSURE IT IS FREE AND WILL SPIN WITH NO EXCESSIVE UP AND DOWN IN AND OUT SHAFT MOVEMENT. PRIME THE FUEL SYSTEM ALL THE WAY UP TO THE INJECTOR NOZZLES. BEFORE STARTING ( IM ASSUMING YOU HAVE ALREADY ROLLED ENGINE AT LEAST 3 COMPLETE REVOLUTIONS TO ENSURE NO FLUID IS IN CYLINDERS) CHECK ALL YOUR CONTROLS. ENSURE THE STEERING CLUTCH, TRANSMISSION CLUTCH, STEERING BRAKES, TRANSMISSION DIRECTION CONTROL, TRANSMISSION SPEED CONTROL, BLADE AND IF EQUIPPED ROOT PLOW CONTROL, COMPRESSION RELEASE, DECELERATOR AND THROTTLE LEVER CONTROL LINKAGES ARE ALL OPERABLE. GO AHEAD AND SOAK ALL THE LINKAGE PIVOTS WITH A GOOD PENETRATING OIL AND AFTER THAT A GOOD LITHIUM SPRAY GREASE YOU WILL HAVE TO REMOVE THE FLOOR PLATES. IM SAYING ALL THIS IS FOR #1 SAFETY. YOU DONT DONT WANT A RUN AWAY MACHINE WITH FROZEN CONTROLS. WHEN STARTING IT. AFTER ASSURING ALL FLUIDS ARE ARE ACCEPTABLE ENOUGH TO GET HER HOME BE SURE TO FOG THE ENGINE WITH WD40 TO LUBRICATE UPPER CYLINDERS AND VALVES. I WOULD TRY TO AVOID ETHER IF POSSIBLE. IF YOU CAN FOG IT GOOD ENOUGH WITH WD40 IT WILL START POPPING OFF BUT BE SURE TO HAVE ANOTHER PERSON AT THE CONTROLS AND HAVE THE INTAKE OPEN AT THE TURBO SO YOU CAN SMOTHER IT WITH A BOARD TO SHUT IT DOWN IF THE GOVERNOR IS STUCK, DONT NEED A GRENADE. ONCE IT IS RUNNING SET THROTTLE AT ABOUT MID HIGH IDLE AND LET IT BLOW OUT ALL THE COB WEBS. THEN BRING HER DOWN TO IDLE AND OBSERVE OIL AND FUEL PRESSURES. WATCH THE TEMP TO ASSURE PROPER COOLANT REGULATOR OPERATION. VISUALLY INSPECT FAN AND BELTS AND LOOK AROUND ENGINE AND UNDER MACHINE FOR AND LEAKS. ONCE YOU FEEL CONFIDENT YOU CAN KEEP TRANSMISSION IN NEUTRAL AND ENGAGE THE TRANSMISSION CLUTCH. YOU SHOULD FEEL A WALL WHEN PULLING THE LEVER BACK AND WITH MORE EFFORT FEEL IT SNAP IN AND YOU WILL HEAR THE TRANSMISSION GEAR TRAIN SPINNING. KICK IT BACK OUT AND PUSH IT FORWARD TO SEE IF THE TRANS BRAKE IS OPERATING( WHICH SHOULD BE INSPECTED AND GREASED PRIOR TO STARTING) YOU WILL NOTICE A RATHER RAPID STOP OF TRANSMISSION GEAR TRAIN IT IT IS WORKING. CHECK YOUR BRAKES, STEP ON THEM TO ENSURE THEY ARE OPERATING AND THAT THE HYDRAULIC BOOST IS WORKING. SAME FOR THE TRANSMISSION CLUTCH IT HAS A HYDRAULIC ASSIST TOO. BRING HER DOWN TO AN IDLE AND PUT TRANS IN LOW IN YOUR PREFERRED DIRECTION AND EASE INTO THE CLUTCH TO SEE IF SHE MOVES. IF ALL IS GOOD LOAD THE OL GIRL AND TAKE HER TO HER NEW HOME. I DID FORGET TO CHECK OR PUMP UP THE TRACK TENSIONERS BUT THEYRE PROBABLY GOOD IF NOT YOU WILL SEE A PILE OF GREASE AROUND THE PISTONS AFTER YOU MOVE IT INDICATING THAT IT NEEDS PISTONS AND OR SEALS. I FORGOT YOU CAN SPIN THE HECK OUT OF IT WITH THAT PONY MOTOR WITH THE COMPRESSION RELEASE ENGAGED TO SEE OIL PRESSURE.
