I have been using electrolisys to derust them. so a couple of questions , am I being completely stupid to attempt to reuse the discs? does anyb...

450 hydraulic hoses

hi guys, I'm replacing a bunch of hydraulic hoses on my loader and backhoe today. do I need to bleed air out of them before final fitting hookup? with some of the hose run lengths it seems that an air pocket in the ram would not go back to the reservoir when cycled.

Re: What is the Cut-Off Temperature for Bulldozers?

the jd manual calls for atf at cold temps, it has a low viscosity and the proper additives for hydraulic seals and such. DO NOT put diesel or any engine type oil into a hydraulic system, it will destroy seals and does not lubricate the internals properly.also not a good idea to mix hydro fluids try ...

Re: 450 diesel engine no serial #

I put 10/30 from tractor supply into it along with lucas oil .I didn't want to put high dollar stuff in until I figured out the coolant contamination problem.today I'm adjusting the oil pressure regulating valve a little bit. guess I could be running a heavier weight oil in it which would probably b...

Re: Body more worn out than my equipment

Re: 450 diesel engine no serial #

Re: starting 450 after 15 years

I put 1 1/2 gallons of coolant into the radiator to fill it up. drained the oil sump and got 1 1/2 gallons of coolant out before oil started coming out. for a second almost wondered if I had opened a coolant drain of some sort ? water level has stayed constant in the radiator for 24 hours now so may...

Re: starting 450 after 15 years

thanks for the good advice, I didn't give the crank and cam much thought but I see how that would be way more expensive than some rings and new liners. I like the zip tie tip. I will try to pull the injectors out to lube the rings but if I cant I still have to start it to get it where the tow compan...
