SOURCE: where can i put lubricating oil for karcher jet wash machine

It sounds like you are referring to the oil in the swash plate housing. You can use a multi grade motor oil such as 20w50 or 10w40. Fill to about half way over the swash plate. If the old oil has gone amilky colour, please replace the oil seals first.

You may need to replace the jug gasket or whatever gasket it is leaking from. If it is by a connection or line, you may be able to use silicone or o-ring

SOURCE: Karcher K2.26M water leak

I have the same Problem, the leak is from the seam of the Manifold housing. There is a small crack in the seam. A manufacturing defect.. A New Manifold Complete Replacement K2.26* Part # 97501760 is $61.03, about the half the price what I paid for this pressure washer at Walmart... :( If under 1 year old, and you can find a receipt,Karcher will replace the whole Pressure washer under warranty.

SOURCE: karcher pressure washer leaking oil

Usually electric pressure washers only have oil on the pump, so its very likely that you will find the problem there. I'd say check all the pump seals and if that doesnt solve the problem, you can check to see if all bolts are tight when you close the pump back.
If by any chance you are looking for a new machine and/or parts for your machine, log in to where you will be able to find pretty much anything for your preassure washer.

My sunbeam alpine 65 series 2 is leaking oil from the oil filter seal and I can't stop it, any ideas

Remove the filter and check you haven't damaged the threads as you put it on. The filter should only be fitted HAND tight and a little bit of oil should be smeared on the rubber seal ring. This stops the seal twisting out of place when you tighten it. Over tightening will strip the threads on the filter destroying that part of the seal.

Karcher dirtblaster leaking at the end

If it's leaking it obviously has a bad seal or is broken. I would try to disassemble and see if it has a seal or not. Sounds like you could have a bad "O" Ring or some other type of seal leaking but I'd bet on an "0" Ring damaged or wore out. Dissemble it and see what is sealing it and proceed accordingly.

What causes the oil to leak?

1. Oil generally leaks because of mechanical failures.
To contain oils there needs to be a mechanical seal of some sort. This may be for the sake of argument a rubber ring or a flat strip or gasket seal of an appropriate material or even a propriety sealing agent which can be squeezed from a tube.
Simplistically a jar can be filled with oil and the lid which has a seal in it is placed on top secure enough to stop the contents leaking.
If that jar is connected to other jars by pipes to form a system they too need to have seals inserted where they join the jars so that there there are no leaks.
2. Seal failures can be caused by heat, chemical corrosion and or erosion , mechanical stress such as vibrations or bending or longevity of material properties such as the elasticity depreciating. Finally other causes can be attributed to wrongly fitted or inappropriate types of seals being fitted.

Oil leak 2000 alero, just replaced plug, not it, leaked out all the oil after I drove it 20 miles, please help, could it be a gasket or what

Check the oil filter. The old gasket might be stuck on the engine (two gaskets stuck together), or the new gasket might be defective, misaligned or missing.

Water leaking out of the bottom of the pump - low pressure leak, light stream

Will be a gasket, o-ring or seal that has blown. Could even have a cracked fitting or a split hose.... remove housing where leak is coming from and inspect. call service part agent and order new part (make sure you grease seal or o-ring with rubber grease. If it is a gasket you may need to use a gasket sealant and find out what the torque setting are for the component you have disassembled.
General quide is: 10mm head = 10 - 12 newton meters 12mm Head = 18-20 newton meters
Hope this helps... hard to diagnose accurately with your vague description

How do i repair oil filter housing leak?

The oil is most likely leaking from the oil cooler seal. The oil cooler is the square aluminum piece that the oil filter screws onto. To replace the seal, remove the filter, remove both coolant hoses that attach to the cooler, remove the nut that secures the cooler to the block and slide the cooler off the tube. Replace the rubber o-ring seal which is available at the VW dealer. It's inexpensive. Replace everything in reverse order. Good luck!

Oil is leaking from around the oil filter

The rubber O-ring from the previous oil filter most likely stuck to the engine when filter was replaced. Remove oil filter and ensure only 1 rubber O-ring is sealing the oil filter to the engine.
