Hi, im looking for spare parts fo a kango type m electric hammer no51877m its 50+ years old & i need the two springs, motor brushes & oil seal thenks steve powell

This is an indication that the hammer needs service. When you take the barrel off you will see the striker. There is a piston inside the striker, when the rubber rings on the piston wear out you have the problem you describe.
time to replace the motor brushes clean and regressed, make sure to use the correct grease, Check the backlash on ring and pinions. Don't put too much grease on the piston or it will stick and not strike. Good luck I forgot to ask which version. This is for the uk atlas coco, silver with blue or red handle

It is very likely the carbon brushes that contact the motor to transfer electricity to the windings. those tend to crack and get stuck or wear out. They need to be moving in and out freely and have spring pressure pushing them in towards the motor. you can get new ones cheap at ereplacementparts.com if they sell them.

Hi Vicki
Is it the old all silver one or the new one with the red motor housing?

If these are the original Kango kangos then you are out of luck. They have been obsolete for many years now and no parts have been manufactured for a long time. The name was bought by DeWalt and they didn't do much with it. The Kango name is now ownd and used by Milwaukee, but there machines do differ alot from the originals. There were a few main models and the main mid sized breakers were the 900 (hammer only) and 950 (rotary hammer) There were a few facelift/variations of each (K, X and B I think) and they did use a couple of different sized seals/pistons/cylinders.
If it is one of the Milwaukee models you can look up diagrams here...

What kango hammer do you have? I am most familiar with the UK kango 900 and 950, pre-milwaukee.

Milwaukee K900K or the English Kango 900K Blue old or Red some younger handle it differs very much English Kango was using a thick brown grease in 2 chrome colored plastic bags . the Milwaukee K900K has a lubrication grease also not oil but be aware of the operating hours i f you have a K900K model from Brand Milwaukee tools replace also a service kit and the bearings on the armature is important also Its neccesary to protect you from damage
if you have a English Kango its hard and expensive to get a spare parts and most times the tools are worn in the front of the chisel stroke bolds do not get right close and the piston pins are worn it was a good tool about 20 years ago i have serviced much of them . but the first thing thats important that its air-tight in front of the chisel and everywhere thats having a mechanic/pneumatic duty



Milwaukee Services and fill k900k with (IMPORTANT) the right number

\charlie use sewing machine oil, as for a book on it put the make model into google and a pdf might be available as for parts not really unless you sroce them through the paper or ebay

what country are you in? in australia atlas copco are the distrbutors. i`m sure you can find out on the internet

Milwaukee now owns Kango, unfortunately I believe the 950sv is the old style. Parts are no longer avail. I have about 20 of the breakers. It is really too bad, they were great machines.
