There will be small seals or "O" rings in the pump shaft cover. Manual details will be on the net but best if you have a case technician repair it as it will be done quickly and properly.

I have installed a new starter on my 580C backhoe When I turn the starter switch it will not engage wheel and just akes a whirring sound Have taken it out and reinstalled it but get the same results

I can talk to you in automotive terms, I know nothing about a backhoe.
I can usually lay the starter motor on the ground, hook up jumper cables properly from starter to battery, at the least, it should kick out the starter drive gear and spin. If it doesn't kick out the drive gear, starter is faulty. I don't know if starter solenoid sits on top of starter motor? I replace as an assembly. Did you check flywheel teeth? I've never worked on a backhoe.

Where do I check the brake fluid on a 580C?

I am going to have to guess you are referring to a 580 C Case backhoe.
In any case never ever put anything in a brake fluid reservoir but brake fluid, and the right fluid to be sure, or you will seriously damage or destroy the brakes "forever".
The brake fluid reservoir is usually plastic, and often you can see through it just enough to see the level of brake fluid.
It should be located near the front of the brake pedal, and is usually sort of white in color, with a black cap that can be screwed off.
God bless your efforts.

I have a 953 track loader the throttle shaft on the injector pump is leaking oil do i have to replace the injector pump

Bad O-ring on shaft. You may be able to do it yourself, but definitely not a complete pump unless you have a cracked pump or serious injection performance problems thus bad engine performance. Double check pump shaft. area. may need to remove a cover to the drive. Usually, there is a diesel return line I suppose there is a slim chance that is pinched or plugged somehow. Check to make sure it's clear. Possible that supply line to Injunction pump is leaking at the connection, also usually a bad O-ring. Find a leak by
wraping a paper towel in places to discover the leak. Or there is
a black light kit with dye to discover leaks.

Any Codes?

Check for vacuum leaks with a can of carb cleaner engine running - when engine race up or bogs down there is a leak. Spray all around intake, vacuum hoses, brake booster, and throttle body.

Can I Replace The Throttle Shaft O Ring Without Removing The Injector Pump On Pergeot 405 Diesel To Stop Fuel Leak

I have done this before a few times, you can remove the top of the pump in situ. It is very awkward to put the top of the pump back on though. but can be done:)

My 1965 turbocharged John Deere 3020 started last week but I couldn't get it to throttle up past idle. I shut if off to investigate and now it won't start. Throttle linkage is fine. Fuel lift pump seems...

Try looking to see if the fuel-shutoff is working, open only one fitting instead of two injectors. Check the glow-plugs or intake heater if applicable. You can put an in-line electric fuel-pump in place. This can help you find out if there is a hidden fuel-leak, system loosing its prime, or bad lift-pump. If this still doesn't help then you may want to dig deeper and see if the shaft broke on the injection pump. Remember to mark the pump so you put it back exactly where it was. Rule of thumb is to set the timing to TDC on cylinder #1. Mark the gears with ink or white-out. and the injection pump case too. Let me know how its going.

My 1986 volkswagen jetta won't stay running and i think it has something to do with the throttle body or injectors, when i start it, it stays running for 4 to 5 seconds then shuts off how do i fix this...

normally you will find if you replace the filters it should solve the prob although if it does not then fuel pump acumulator valve might be faulty or vacuum hose to it leaking ( located on the end of the fuel rail to injectors)
