What oil should i put in Fiat 411r hydraulics?

To remove, clean, and replace the hydraulic oil filter on a Fiat 411R PTO unit, you will need to follow these steps:

1. Locate the filter: The hydraulic oil filter is typically located on the side of the PTO unit, near the bottom. It is often mounted to the side of the unit with a bolt or a clamp.
2. Prepare to drain the oil: Before you remove the filter, you will need to drain the hydraulic oil from the PTO unit. To do this, locate the oil drain plug or valve and place a drain pan underneath it. Then, loosen the drain plug or valve to allow the oil to drain out.
3. Remove the filter: Once the oil has drained out, you can remove the filter. To do this, you will need to loosen the bolt or clamp that holds the filter in place. You may need to use a wrench or pliers to do this. Once the bolt or clamp is loosened, you can carefully remove the filter from the PTO unit.
4. Clean the filter: Once the filter is removed, you will need to clean it. To do this, you can use a degreaser or solvent to remove any dirt or debris from the filter. Once it is clean, you can set it aside.
5. Replace the filter: Once the filter is clean, you can install the new filter. To do this, simply reverse the steps you used to remove the old filter. Make sure the filter is properly seated and tightened down, and then refill the PTO unit with new hydraulic oil.

It's important to follow the manufacturer's instructions when replacing the hydraulic oil filter on your PTO unit. If you are unsure about any of the steps or have any questions, it's a good idea to consult the manual or contact a mechanic for assistance.

This is why they called them 'Tappets', in the days before they called them 'hydraulic valve lifters'.

Make sure your oil is clean and at the correct level. If it continues, the valve lifters need shimming to take out the 'lash', the gap between the lifter and the valve stem.

sounds like the valve clearances are incorrect if your engine has got adjustable valve clearances check that 0.40mm inlet 0.50mm exhaust but the engine changed in 1999 to hydraulic valve lifters and when you refit origional folowers you should compress them to remove the old oil or the new refubished cyl head/valves will have no compression because the valves are not seating

if manual transmission and hydraulic clutch --replace the clutch master cylinder
or cable clutch ---replace the cable
or--- replace the clutch ( 1st two options before the clutch as they are cheaper)
if automatic ---change the oil and have the bands and clutch pack adjusted ( use an accredited auto transmission speciliast shop who has experience on your vehicle)

stop at an auto parts. they will show you where the power steering oil goes.

Service the brakes and ABS .

The oil cap should be right on top of the valve cover, also for summer I would recommend 5-20. Hope that helps you

10w40 semi synthetic oil. or 15w40 is even better. its up to you.

Clean the engine block with a compressor and find out where the oil is coming from.
If there is no leak, and motor stays clean, then the oil is being combusted inside the engine, and you should get black smoke from exhaust. In this case it is time to a major repair to the engine.

you neede 10w/30 or 15w/40 semi synthetic and it takes 3.75 ltrs
