Question: 11305 Demo Gun

villaroj

Demo Gun doesn't fire into working order. I am getting electrical power, but not able too generate piston/striking action. HELP!

Question: Owner

945201

I have a Bosch 11305 that seems to work fine then loses power and smells like something is burning, any clue ? Thanks

Question: Bosch 11305 Jackhammer Bit Over ...

pissythecat

Could a worn locking bolt cause the bit to get stuck so there is little to no hammer effect ?

Reply: Bosch 11305 Jackhammer Bit Over ...

pissythecat

More on the loss of hammer effect. When the bit gets stuck, if I use a hammer to beat the bit back into the jackhammer the hammer effect works for 20 seconds and then the bit gets stuck again.

WJA

Hello pissythecat,

The locking assembly, if worn could be the cause of the problem you are having, that would be the least expensive fix. You might want to inspect the bit to make sure it is not worn where it fits into tool holder. Also check the tool holder for wear.

WJA

my breaker is leaking black grease/oil and does not have continual breaking ability

Question: LEAKING FLUID

DENNIS

Oil is leaking from the lower body on my Bosch 11305, is this an O ring replacement fix?

Does the piston chamber get filled with oil? If so how much and what type?

villaroj

Hello,
Just wanted to revive this question! (2012 FEB.) My problems is exactly like PAT's, no striking/hammer action! Maybe Cmoorejack can possibly HELP?!

Reply: Everything Working Fine But No H...

Tinkerdave

Hi Pat and Villaroj,
What your going to have to do is remove the the front striker assembly and find the problem.It could be a number of things but replace your o-ring as sets or in other words don't replace what looks worn as the o-ring all have ware on them and replacing one or two will only half fix the problem. Once you have disassembled the striker assembly you will need to clean it and be able to see what of any hard parts are broken.Most of the time this will be obvious.Example would be a broken connecting rod or frozen striker.Once you find the problem ,replace the part and use the Service Pack Part Number: 1617000036 and reassemble.I wish I could give you a simpler way but the way I'm explaining is the right way to repair this tool so as not to have recurring problems with it.hope this helps.Good luck.

Question: Piston Travels, But...

Carl

Hi. My Bosch 11305 demo hammer seems to be in basically good order, but the tool is not being impacted by the impact bolt. I have confirmed that the piston is shooting in and out just fine (motor, gears, piston all good) but it is as though the impact bolt striker are not long enough to reach the base of the tool. Ideas?

Question: Fluid Leaking

Doug C

How much oil is needed from the service pack I received. Is the oil poured into the chamber noted
on Fig//abb.1 # 828

Question: Leaking Fluid

Paul D

I went to use my Bosch jackhammer after lengthy storage and I see evidence of an oil leak on the lower body. Is this fluid I need to top off and/or replace O rings?

I am going to be replacing all of the piston rings and O-rings. But I need to know the correct position to place the Piston, Striker and Impact Bolt when I reassemble it. Also how much and what to greese.

Question: Bosch Demoltion Hammer 11305

Milillo02

Hey guys i have a bosch 11305 hammer. I wanted to know if any1 has a maintenance manual and or owners manual. Mainly i wanted to know if this tool needs lubricating/greasing everyonce in a while. it makes "whining" noises sometimes and i dont know if its lack of lubrication or not. Any1 can help? thanx

Reply: Bosch Demoltion Hammer 11305

cmoorejack

Hey Milillo02,
They do need maintained once in a while..new grease and oil..even when the tool is not used for long period of time the grease's and oil will break down or link removed when the the brush's need to be replaced is the time to do it..[the brush's actually have a 'pop out' feature when they wear sown so the tool quits running] The most crucial components to service is the gear train and the piston and striker assy..along with changing out some o-rings and such:)
as far as the whining noise it may or may not be a problem and can be a characteristic of the tool..if it changes or gets worse,then it is a cause for concern..:(
Parts and breakdowns avail at eReplacementparts.com : Power Tool Parts and Tool Repair
hope this helps.?

Milillo02

Thanx alot. Yea that helps. But my problem would be what grease/oils to use? What to and how to greas them. I meane inside the casing does it have like zerk grease fittings or am i supposed to take apart the gear case and grease it like that? Which "O" rings should get replaced? I saw the parts breakdown of the hammer but there is more than one seal.. :)...a nymore help would be greatly appreciated.

Reply: Bosch Demoltion Hammer 11305

cmoorejack

Hey M,
The best thing to get is the service pack..it comes with the o-rings, grease and brush's..
part # is 1-617-000-036..
no grease zerks and you will have to completely disassemble to service..the oil that is used is a light air tool oil on the o-rings[just a little bit] It doesn't come with the kit but it is a trick of the trade..if you don't have any oil just use the grease on the o-rings sparingly..be careful not to have too much in the piston/striker chamber or the percussion will be weak..
When you are ready to disassemble and service it is recommended that you go to a happy place,light some incense and play some soft rock music..I'm just saying..
Kidding..[sort of]..just be patience and have a breakdown available and you should do just fine..

Question: Bosch Demolition Hammer

Macguyver

What I need to know is how to get the eccentric gear # 11 (1616317015) off of eccentric shaft # 9 (1616110032 ) . In the break down pics it lists p/n 78 but there is no listing for that #. Looks like a circlip but mine does not have one, the on I have looks like it is pressed on and takes a special gear puller.

Reply: Bosch Demolition Hammer

Dale

Yes you will have to press the eccentirc shaft out. To split the case. I haven't repaired one for a while. But I don't remember a c clip ether. Hope this helps. Dale

Thanks for input, used my puller for a power steering pully for a GM vehicle worked perfect.

Question: Bosch Demolition Hammer

keith@acr-corp.com

Looking for bevel washer installation information. The washer came out during disassembly but I did not see if the cup side is in or out. Link to the service info or manual?

Reply: Bosch Demolition Hammer

cmoorejack

Hey Kieth,
The bevel washer should face the front of the tool..so that the shoulder of the impact bolt fits in towards the bevel side..
hope this is helpful..

33 year masonry contractor

I bought this tool new in the 80s and only had to buy 3 kits of seals and grease. Can't tell you how many hours it has on it. I do masonry re hap as a contractor and I never had such a long durable tool ever. Still own it today and its on the job truck every day. I'm a Contractor and my letter hear is not for advertising means. Its just the plain truth,
