How do i fix oil leak in seals of jackhammer


by a service kit that are made for your model

I do you a suggestion how you can do it yourself if you have a burner to heat up the bolts because of loctite sealant i think you know something of forces on that parts ? because of the tools that are neccesary to service it .
Here is a suggestion of a brand that is maybe there or coming in your Country . thats why i do this suggestion by a dutch link .

If you know the brand of your hammer ? sometimes bought secondhand and no modelname google it on 3 words powertools the brand service or choose pictures if you will see pictures where you can see your hammer but there are can be marketing technical differences by the models because a suggestion i made by Hitachi the H90 and H90SE are not compatible by service kit a part of spares can only be used.
The time you spend is meaningless if you only think its leaking oil. because there is a thin lubrication inside most jackhammers and if that's leaking ,the working hours are on it, for time wasted re prematurely burned grommets make high-priority work bolt seal the front of the machine at the stroke chisel the first rings oil seals as well as the size of the stroke bolt must be tight and smooth, as if only a little air leaks burned den all your new o-rings (ie be hard in the short term) by overheating, use lubricants, not just fat because of the high temperature internal structure and the thermal conductivity of the parts together.

What kind of oil can I use in my hitachi H65?


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.

I have a hitiachi DH38ye drill and it won't accept the Bosch spline bits. they go in ok but the chuck won't lock. The drill accepts the hammer bits fine but won't accept the drill bits


you have me stumped on this one. The tool you have is a spline shank hammer and it should accept all standard spline bits and also hammer iron that is made for these. Is it possible that the Bosch bit has a burr on the splines not allowing it to lock? I have checked the Hitachi site and found no reason it would not work. I will continue checking though.

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.
