- Taking a look inside the Black & Decker 40 volt hedge trimmer. This was originally on a different channel of mine so I'm sorry that the annotation links are not there.

Great Video! Yesterday I sent email to B&D Customer Service asking for maintenance schedule for the internals, like gear lubrication. The message back was there is none and opening up the unit would void the warranty. WHAT! If you don't lubricate gears, they will fail sooner than running dry. So this video will get me going in disassembly and lubrication. You are doing a service for B&D customers far beyond what I got from the Customers Service department.
Just FYI, this trimmer did not last. A month after this video, there was smoke coming out of it and it never worked again.
@@AutistiVision Not surprised. Mine has a "burning insulation" smell recently. I suspect a fresh motor would be good to have or use this unit only for light duty work. Glad you posted the failure.
Thanks for this detailed video, I took mine apart to sharpen the blades and was having trouble reassembling the trigger. It turned out from watching your video, that the missing part was the trigger pin, which had fallen on the garage floor. I cleaned and sharpened the blades and freshened up the gear grease with Duralube, it works and performs like new.
I'm so glad my video helped you! Thanks for telling me. I really enjoyed making videos like these and I had always hoped they might be good info for somebody. :)
Late to the discussion but for anyone that might find this thread. The black stuff he talks about is, in fact, metal filings most likely from the pinion drive wheel attached to the motor shaft. You can see the shiny worn surfaces in the video.
The blade drive mechanisms are identical to B&D trimmers including AC models driven by universal motors. I owned one of these and it lasted about 5 years or about 10 hrs of use. What eventually happens is the drive pinion wears out since it is very small and only 1 tooth is engaged with the large reduction gear.
The wear is accelerated by larger blades and when the blades become slightly dull thereby increasing load on the drive gears and motor. This is further accelerated by the grease drying around the gear contact area. The result is that the gears will start jumping teeth. You will recognize this as it will start to sound like a machine gun with an increase in vibrations and poor cutting action. At this point it's all over and any attempt to repair will involve sharpening/replacing blades, replacing the motor since ( for the universal ac motor at least) the pinion is integral to the motor shaft.
This could have been mitigated by a replaceable pinion gear which would allow economical replacement of the worn part instead of replacing entire motor and this would have added a few dollars to the cost but then you would not be back in 5 years to buy a newer ( and cheaper yet) model.
Safe to say the unit in this video is long gone to that dumpster in the sky unless it was used sparingly on tender leaf growth and blades sharpened meticulously every few hours of use.
Oh yea, it has gone to that great dumpster in the sky. If I say I smoked it, it's because it literally started billowing smoke out on the day that it completely stopped. I have a Ryobi brushless now and wow, it's nice.
@@AutistiVision Hello, pls advise Ryobi model number you are using now. My Black&Decker smoked too. Thank you.
Was torn between this and the much more expensive Stihl - maintenance access alone for the Stihl seems much better
Get the Stihl
I just want to know how to charge this thing. I found a few battery pack things and some plugs for Black and Decker cordless things but don't know which goes to which? My husband passed away 5 years ago and am cleaning out the garage.
Shaft of motor snapped off on mine, terminal, they don’t sell replacements, lasted 10 years of pretty heavy use 🤷🏽♂️
I am surprised yours lasted so long. Mine broke shortly after making this video.
@@AutistiVision I actually just bought a new one since I’m invested in batteries and chargers for it and there other tools, I really liked it!
It seems my motor's gear shaft has had all it's teeth shaved away, it's such a perfectly cut recession that I didn't realize it wasn't manufactured this way, but there was a visible gap between it and the big gear. This video seems to be the one place on the internet that shows the motor's gear shaft as it's supposed to be, and this confirmed for me what the gear shaft is supposed to look like. Sadly I can't find a replacement motor.
@@audx2338 Glad it helped, but this trimmer is really no good. I highly recommend the hedge trimmer from Powersmart. I do lots and lots of reviews on one of my other channels and so far that one has been the best hedge trimmer by far.
Do you have the serial code or part number for the motor? I wanna look at the specs
The 3R1741 string doesn't bring up anything
I'm sorry, I threw it out when it broke.
How is the motor separated from the transmission Housing.I have yet to get a response from B and D
2 bolts on blade assembly, if it’s like mine the shaft sheared off, motor runs gear doesn’t
Please "show" how to remove the battery! Thank You!
