Thanks for your input. I do have the schematic parts layouts. The picture of the piston does only have the one O-ring.
But, looking at several video's that are out there, one can find a piston with two O- rubber rings on it. Mine does have two.
I have two of these drills. One is an 11240...
I just saw a video showing the two rings. This gentleman, just ignored the smaller one and replaced the larger.
Never said Boo about not do it.
He has a lot of video's on U tube and does alot of repair on tool (he is from Irland).
I recently took my 11240 Hammer Drill apart. I found that the piston has two O-rings on it. I have the 11240 Diagram and it doesn't show both O rings on it .
The diagram shows two O-rings close to each other, but I believe that one is for the piston and the other is for the striker next to it...
Dyermullet,
I looked at the http: that you sent. Combo stator and armature. More importantly....... look at the bottom shaft of the armature. This is the armature that will work. Doesn't have that ring around it. Flat and a stop. That is if they send that one to you.
It is an Amazon link!
Texting information is not the easiest thing to do in a forum.
Thank you for looking at this anyway and providing what ever you thought was informational help.
You asked for a "Link to Amazon listing?"
That is exactly what I sent. A link to an Amazon listing.
You didn't ask for a link to what I bought. Doesn't matter anyway.
Problem found, prolem solved with the help from this forum.
I bought this Drill for $25.00 knowing that it was bad. The armature and service kit was around $150.
I pretty well new from the get go that it was an armature. Looked like it was a piece of cake to fix.
One last comment about the purchased armature.
Those were pictures of armatures I got...
