Yes, I see now. My mistake. I removed all of the gearing as a unit and then unscrewed the motor. So, lots of gears, it looked similar and I assumed it to be the same. Thanks for the info.
Hi Harold, thanks for the comment, this new problem has been caused by the replacement of the original bushed motor with this new bearing motor. So the chance of having problem happening in any of the new Yaesu is greatly increased. Yes some rotators may have less grease/oil to cause this problem, only time will tell. I have had a couple of customers hand me their brand rotators to do the upgrades I do, before they install the rotator, Regards Peter
I have the exact same problem with my 3yr old GS450 adc. I stripped it down after watching your excellent video and sure enough, there is oil dripping out of the servo motor. When i apply power it has the same slow jumpy movement. My question is: this unit is exactly the same inside as the G1000, including bearings. where is the added value?
Hi Mike, thank you for the comment, Yes I have found the same issue with a couple of my customers G450ADC & the G450CDC but I never made a video on them. The G450CDC is not the same inside as the G-1000 (even though they both use the same lower housing), they have different gearing & layout, different gear pitch, gear chassis are also different. The G450 only has one set of final drive gears onto the top housing, where as the G-1000 has two sets of final drive gears onto the top housing, These final drives have a different pitch in both rotators, small pitch for the G450 & larger for the for the G1000.

Hi, I disassembled a G450 and I didn't notice where the cap is located, how do I reset the potentiometer that will be calibrated to the rotator? Thanks
It is not understandable that I dismantled my 450, the switches for the rotation limiters are located exactly in front of the 7-pin plug and that you are the train that put the engine with the switches to the left at 90 degrees...how does it work? Not clear
would you know if my yaesu control box needle is not going smooth, likes flutters and jerks going to the next degs. would that be the rootor or the control box that is bad? its a G450ADC, Thanks Tom K1CXS
Hi Tom, thank you for the comment. There could be a number of things that causes that. 1) Faulty potentiometer or slipping POT gear in the rotator &/or the controller, 2) Control cable &/or plug problem, 3) Controller PCB problem, 4) Question is the rotator moving in a similar way slow & jerking motion. For more info please get in contact via my web site the link is in the description. Regard Peter of Duoro.

Yes this is a current version rotator (under 4 years old I think the customers said). This version of Nidec (DMN37) ball bearing motor it now used in the G-1000, G-800 & possible the G-450DC as well, going on what a customer described to me about his G-450DC that had the same problem. And yes this could be an on going problem if the bearing in the top of the motor is not covered up, too stop oil pooling up on top of it. If Yaesu is using oil instead of grease in the BK Brake assembly this is the main problem, but also don't forget grease has some oil in it, which can separate & cause the same problem. As stated the original DME series motor (that was used in these rotators) had bushes instead of bearings it not have this problem.
@@plproductions8887 There are other brands of rotator around other than Yaesu, like Create & PST. Plus it all depends on what antenna your you are going to be put above it. I'm the Create dealer for Australia, you can view their RC5 series on my web site, while there have a look @ my Rotator Sale page & view all the refurbished rotators I have in stock.
Interesting, I have a motor not running with 10v +/- it makes an attempt but no run. I did not notice oil, and did not dismount the motor. I also have a DMN37B-046. I need a replacement motor.
@@frankhagen4380 Hi Frank, I would bet, the same is happening to your DMN-37 (covered in oil on the inside). I have this model motor in stock, get in contact with me via my web site which is in the description. You will be stripping down & cleaning up your motor when you hear the price of a new DMN-37 ($250.00 AUD).
Hi Jim, Thanks for the comment. The bearing race & it's seals were OK. The oil has come down from the BK Brake assembly, migrated between the sub chassis & motor plate as well as between the motor & motor plate. Then pooled above the bearing race housing & bleed down through the bearing onto the wire windings, down & out all over the commutator. Regards Peter.
Good call Peter, I have a buddy in TX with this rotor, Been using it for 10 month's since new.
Watched this while having Tea I loved it the wife didn't understand much. Enjoyed your film not keen of yaesu rotators.
Great work Peter...

Great video sir!
I’m about to pull the trigger on one of these. Have you found a lot of these with this problem?

Is this an newer type YAESU G-1000 rotator.?? And could be a on going problem??

In the market for a rotator what would you advise looking at a g1000dxc

Looks like to me that the oil seals in the bearings let go.

ur audio is horrible ,sounds overdriven hard to listen to
