SOURCE: What kind of oil can

Hitachi hammers use 30wt non detergent oil. But you can use lighter oil in cold climate. If too much oil accumulates in hammer, it may just come out bit retainer or build-up inside gun. Oil enters the hammer by wick process, of wick is missing oil will enter too quickly. If your brand label is glued on, you may have a hitachi copy from china (most hitachi labels are rivited on). China hammers may use different oil.

How to put oil in Hitachi H65

OIL ?? I think Hitachi has always a yellow grease lubrication
hitachi grease demolition hammer Google zoeken never seen heart of oil in Hitachi demolitions. but there could be models in your Country thats new for me .
Otherwise BOSCH HILTI and the one and only brand DUSS demolition hammers and also a few brands of Chinese hammers need oil lubrication . an expensive sinc-free hydraulic oil the same as used in some pressure washers life lasting oil but for HItachi look at the link for the grease 2 tubes a enough . good luck and dont forget the piston pin to replace with a new not only the gaskets and o-rings and also the oil and dirt seals on the front where the striking pin is that must be absolutely not air leaking because all your work burns in a few months again out . you can start all-over again.

Will a blocked pcv cause oil to blow out crank seal

A blocked PVC valve will not reduce the crankcase pressure and may induce oil leaks. If your lucky, a new valve will fix the problem, but I have never been lucky. Once oil starts coming out it seems to always come out until the seal is replaced. If it's coming from the top of the engine , it may just be a valve cover seal which is usually pretty easy to replace. All other engine seals are harder/more expensive and you have to decide whether the cost to fix is worth the pain of checking the oil, keeping it full, and the mess where you park. Also depends on whether the the oil leaks out abnormally fast - then it needs to be fixed. Usually the leak created by a blocked PVC wont be major - 1 quart @ 3,000 miles.

1996 chevrolet impala ss oil leak rear of engine

Is it engine oil or transmission fluid? Is it driven often or does it sit in the garage? If engine oil, then possibly the rear seal is leaking into the bellhousing as you drive and then draining on the floor after you stop. If ****** fluid, then possibly front seal on ****** is leaking. If car sits for long periods of time the input shaft seal can allow fluid to leak past the shaft. This usually will fix itself when driven. Can't promise it will fix itself permanently. Will not be an easy fix if either seal needs replacing (or cheap).

I have a 2006 chevy aveo and it has developed an oil leak. I took it to my repair shop and they were unable to locate the leak. They said it wasn't a big deal and not to worry about. I am wondering if...

Depending on the location of your oil leak, yes, it could be something that's expensive to fix. However, the reason for that expense probably wouldn't be the parts (it's probably some rubber gasket or seal), but rather the labor required to get to the rubber part and replace it. For example, if your rear seal has developed a leak, you may have to take off quite a lot of engine parts to install the $4.95 (I just made that price up, but it's not a particularly expensive part) seal.

It is possibly worth taking the time and modest expense to figure out the source of your oil leak, just to make sure that it's either something easily fixed or something that can safely be ignored. The tried and true method for tracking down the source of your leak is to get your engine steam-cleaned, so that you can see new leaks instead of chasing down old leaks or things tossed up onto your engine from the road. Then, put a sheet of clean cardboard under your car when you park it for the night. The oil will leak down onto the cardboard, giving you a place to start looking. Note, however, that the oil may have leaked from somewhere entirely different than where it is dripping--the leak may have first fallen onto a structural member, which then permitted the oil to flow downward to the ground. Still, with a clean engine, you should be able to trace the oil drip back to its source pretty easily.

The most common oil leaks occur from an oil filter whose seal has gotten pinched and isn't fitting correctly (something that will fix itself with your next oil and filter change) or a worn oil pan drain plug gasket (also something that can be fixed for pennies at your next oil change). You might also find oil weeping from an oil pressure sensor--again, an inexpensive and relatively easy fix. Next up, you might find oil weeping from a valve cover gasket or possibly even from the gasket between the engine and the oil pan itself. Replacing a valve cover gasket is a relatively minor repair; replacing the oil pan gasket would likely be more complicated because I don't believe you can drop the oil pan on this car without first having to pull the drive shafts (a fair amount of labor). You can also check out your EGR system to see whether any of the hoses in that system have become oil saturated and are starting to drip. Once you're past those possibilities, though, you're quite possibly starting to look at seals and gaskets that are rather more expensive to access and replace.

Lots of older cars tend to start "marking their territory" with the occasional drop of oil on the ground. If it's going to be an expensive fix, you might just learn to deal with that new behavior. A bit of clay-based kitty litter under your car, for example, can absorb quite a bit of oil. Conversely, if you have a serious oil leak, it's something you'll need to address so that you don't run the risk of a catastrophic blow-out, major loss of oil, and the potential for engine damage.

I have a Hitachi demo hammer modle # H 65 When I frist was using it the bit had oil on it. When I got done using it I cleand it all up.When I went to use it again there wasent any oil on the bit after I...

Demo hammers do not oil/grease the bit. The grease in the tool is to lubricate and cool the parts in there doing the hammering. The bit should have grease on the end going into the hammer to make it work in the tool better and make it easier to take out when you are done. You have to put the grease on the bit yourself.

Repair instructions for a leaking power steering pump on a 1997 honda accord. leaking from the shft bearing behind the pulley. need instructions to replace the oil seal.

Not a simple job unless you have proper tools. You'll need a gear puller to remove the pully and a compressiondevice to install the seal and retaining ring. Try a auto junk yard for a used pump. It'll be cheaper and a simple bolt on job.
