Guys I will be conducting repairs on the Surplus/ 2nd hand Bobcat 743/ 743B that my company recently bought. I will be documenting everything so that you guys could help me in giving me some hints/ points on how too's.
I am only using the manuals as my basis, thanks to southpaw and also to thetool as well as to tazza. It's my first time on everything. that's why the manuals and your ideas gave me a good picture on the problem.
I first checked everything and found out that the seals were broken and there's a large clearance with one of my axles and much worse its in the rear. Here is the game plan. Hydraulic System: Hydraulic Oil - Milky White Work - Bleed and Change old Hydraulic Oil need some advice on this - how to bleed and where to start Hydraulic pump.
Weak pressure work - new hydraulic oil and bleed. let air out am gonna try changing oil first before deciding to replace the pump. base on what i read.. how will i disconnect the return valve/ hose so that i could remove all dirty hydraulic oil.. do i need to replace my old hydraulic hose??
Chaincase Chaincase oil is also milky white Work - Change Oil Replace - axle Seals and Bearings Oil - What oil should I use? tools needed - ?? could i just use hydraulic jack to undo the axles unbolting the axles- what appropriate tools to undo them?
Reduction Gearcase Gearcase sounds terrible work - what work should I do. could the reduction gearcase be damaged? or the drive motor is the one making all the noise Replace - do I need to replace the oil seals and bearings?
Electrical rewiring of entire operator panel change new indications for fuel, oil temp, voltmeter, ignition switch, headlight switch. might rewire engine harness. GOOD thing is the Engine. its is in good condition/ but i might replace glow plugs. having hard starting.. plus white smoke when the engine starts.. gonna post some pics soon.. its 3:00 am Sunday.. gonna do the work on monday.. by the way.. I'm from the Philippines.
I already started working with the chain case yesterday. got it down for in 4 hours. One of the supports that we did for the front blocked the chaincase by a 3-5mm. right now my pump is supported since there is no chaincase.
How can i upload pics here?
