[QUOTE="peebeeaitch, post: 61855, member: 8318"] [U]29 Dec 2012[/U] ROPS off. Motor firewall off. Oil tank (original) and petrol tank (not so original) visible. I assume that the blue stuff is not sound deadening padding - the mice have also used this as a source of food as can be seen from the nibble marks: [IMG alt="2012-12-29_FuelAndOilTank.jpg (3264×2448)"]http://bobcat.thesouthpole.co.za/BloodSweatAndTears/2012-12-29_FuelAndOilTank.jpg[/IMG] While continuing my dig deeper into the machine, I came across this connector, which had been plugged into the oil pressure gauge: [IMG]http://bobcat.thesouthpole.co.za/BloodSweatAndTears/2012-12-29_HydTempAndPressSender.jpg[/IMG] The plug is not connected to anything. What is interesting is that the hydraulic oil pressure gauge shows some signs of motion - when turning on, the gauge remains at 0 till the engine fires up and then springs to 1/2 full range. I am now thinking that this gauge has been wired to indicate something else, maybe engine oil pressure or something. The excavation of the machine innards continued and when I could finally access the motors, this is the pile of mulch that I had excavated from within the innards of the machine: [IMG]http://bobcat.thesouthpole.co.za/BloodSweatAndTears/2012-12-29_MulchUnderMachine.jpg[/IMG] 4 hours later, Valhalla: [IMG alt="2012-12-29_ChainCase.jpg (2448×3264)"]http://bobcat.thesouthpole.co.za/BloodSweatAndTears/2012-12-29_ChainCase.jpg[/IMG] Err, maybe not. I am going to have to get hold of an old brake disk to make the special tool to remove the motors. Does anyone have a dimensioned drawing of one so that I can laser cut it? Or is there some other way other people have used? I assume that this oil level is a little high? This would mean that there is leak by from the motor(s)? As I am this deep into the machine, and clearly there are seal issues, would it be prudent to remove the pump and just do it as well while the machine is gutted? How do I check if there is a master link on the drive chains? The manual says to remove the hydrauliuc hoses after breaking the chain, but the only way that I can see to check for a master is to remove the lines, turn the wheels by hand and check. Or is there some other way? Any thoughts or opinions welcome... [/QUOTE]
