troubleshooting milwaukee press tool 2763-20

archibald tuttle

my faithful milwaukee 2763-20 long throw press tool just started not responding to the trigger button despite having solid green light indicating ready to press. but if I knock the thing on its side it presses fine for a few reps and then goes back to the same behavior. kind of like some sensor switch is not springing back or some plug is a little loose was my first guess.

milwaukee techline suspects the planetaries are possibly locking up and requiring too much amperage to start turning and the distinct tap free's them from that position, but I never get a red light, always green and don't hear them try to start. its brushless so i'm not getting the brushes unstuck. literally I just gave the thing a good solid tap and it's like there was never a problem for a few reps. it never slows down or works harder than it used to to my hearing. now I suppose if the bearing/bushings for these planetarys always stop the same place maybe they could have developed a habit of jamming up and the brushless tech reads what is happening so quickly that i never even hear it trying to start.

I've got a nice schematic milwaukee sent me. this being an older unit the trigger switch is no longer available although some outside shops bought up the old stock and have them available for serious money but I don't think from those symptoms that it is the switch.

the switch assembly seems to also have conductors running to in included "bolt sensor" on a common ribbon cable. they tell me the bolt sensor tells the location of the bolt and the pressure. not really clear how it picks up the pressure signal. maybe it will be clear to me once i open the thing up.

just trying to see if anyone ever benched one of these before.

thanks, brian

send it in to be factory rebuilt or replace it.
if it’s not right the liabilities are high.

Isn't it nice that everything made in China has no replacement parts after you spend 2k or whatever they cost now. Used to be tools would last

Well to be fair in this situation we don't know:
-How long the OP has had the tool.
-What if any abuse it may have taken.
-How many cycles.
-How is it stored when not in use.
-Did it ever get exposed to excess moisture.
And on and on.
Like @pecmsg said, send it in.
I do have 2 Ridgid press tools. Price is better. They seem more durable. And Ridgid customer service is a lot better than Milwaukee's (IMO).

Milwaukee tools has a 5 year warranty .

with the price of factory rebuild that really means replace it and then that goes to @EBEBRATT-Ed 's point that it's a pricey piece. now this is older than 5 years @Big Ed_4 so out of warranty. it has had a decent service life but we aren't running new systems all day everyday. if it has 2500 presses i'd be surprised so from a use standpoint I'm not worried about it not getting the right. it really seems like some locater preventing it from starting and when i tap it some friction or return spring fully functions and its ready to go. when i run it it seems to regulate the piston travel just as it always has once triggered and run the entire cycle. never shut down in the middle.

Anyway, that's a dollar a press for the unit ( presuming the jaws don't wear anywhere near as much as the tool and would last through another one or several more press tools). Just when i start to feel i'm getting my money's worth it craps out. Silly me to think this ought to be user servicable and at least able to check calibration or read faults, cycles, etc. does seem a little bit early in the lifetime of a $2000 tool for milwaukee not to have the trigger switch anymore.

haven't ever seen a go/no go template or read of any other way to check it. There is a 7 conductor male plug end under the service cap in the the handle so i'm betting there is an analyzer that you can plug in and read this thing and might be able to tell me what is going on. hoping maybe someone has benched one of these or gained more insight into troubleshooting and calibration but maybe i'm going to be a guinea pig.

@HydronicMike a little of all the above. low cycles, been rained on lightly occasionally. really seems like a physical and not electrical issue. haven't dropped it from height. its tipped over once or twice but not off a bench onto the floor. case is in decent shape. not cracked.

interesting that you find ridgid has better response on service. i got this one because i liked the form factor. i think ridgid has a straight one now. i can't say i'm unsatisfied . this is prob. going on 10 years old, but low cycles. maybe the only thing i'm unsatisfied about is I don't like being sidelined from working on my own tools. if i were able to query for faults and it was unsure on calibration or I could check and find it out of calibration then i could probably get a quote out of milwaukee and send it in. but they give a range $700 to 1400. that's a wide range. i could see at the low end, forget it at the high end.
