Whenever you are taking apart something like that, I found it helps to use a sharpie marker to mark alignment then there is no guessing how it goes back together.
I know it's 2 Years ago , but like I said ! Bro ! I'm catching up ! I'll be working on a 943 Bobcat tomorrow . Keep Digging Brother ! Like your Stuff !!
Interesting to see the inside of a hydraulic motor! Always wondered what was in there. I know it was very frustrating to go thru all that trouble and time for a seal kit, and then find some parts weren't the right size. I can totally relate to that!
Nice work, I think age will be the culprit with seals that crumble, if the case drain is plugged the pressure will force the oil into the chain case. I have seen hydraulic cylinders with little or no use blow out the seals. It would be wise to check the filters in the case drains, but I doubt that was the cause. Hope it all works well!👍😎
Nice work! Looks like you have a great machine there 👍 I just bought an older Yanmar mini Excavator! It’s going to be really useful to have around my property. Take care my friend 🙂
@@Ants_Pants The shaft of the hydraulic motor turned the slots on the drive shaft, on the left side completely and on the right five teeth broke. Drive shafts are expensive in price.
Just watched a guy "HowIdidit" do this same repair to his drive motor. He was very knowledgeable on the motor and showed in detail how to replace all the seals in the kit including giving torque specs. I believe you would find this helpful.
Now that im thinking about it, why was that odd-shaped seal so badly destroyed? My guess is that the case drain line was blocked somehow and overpressure killed the seal, any thoughts?
Hi Ant, good video mate, just in case you are not aware, the higher the current rating of the battery you use with that impact driver the more powerful it will be, you should use at least five amps, you may be already I couldn't see, but just in case you are swearing at a tight nut but only using a 2 amp battery.

I don't know if it is possible but if you could modulate your audio so that your voice commentary (which I much prefer) and your music are the same level it would be very nice. I have the audio set and the music comes on at a much higher level than is comfortable. I jump for the volume control and next your commentary comes on at a much lower volume than is clear. Back and forth back and forth..... I haven't noticed this as much on most of your other videos but this one is really that way. Enjoy the content.
Yes i have done that now. Before rendering a video i have to reduce gain of any music by atleast 50% to make sure their kinda on the same level. Sorry 4 the incovinience.
Can I ask was the issue that your 751 would not turn left? I have a 751 that wont turn left but it goes strait back and right no problem, I am thinking I have to rebuild the same motor you did in order to fix.
Its easy to diagnose. Remove the motor from the machine and plug the case drain line or your hydraulic reservoir will empty itself. The bigger lines will stop leaking pretty fast. Then open the motor its only held together with 9 long bolts if i recall. And see in what condition the seals are. Takes about 30mins. To put back together you need a tourqe wrench though.
@@Ants_Pants I bought a seal kit for both motors just want to start with the most likely candidate, which way turning did you have the issue left or right?
@@billerskine7911 depends on wich side the motor was i swapped them with eachother and the problem went to the other side. Going forward was more problematic then backwards

@@Ants_Pants lol...
Really interesting to see this job done. This one required a lot of mental strength and skill.
A lot

Yeah it was weird feeling. Luckly it had the seals that were busted

Great job. My tractor has broken the slots on the drive shaft, both sides.
ooof, that sucks bro, how did that even happen?

Bonjour , quel probleme de fonctionnement faisait il ?
le moteur n'avait pas de puissance de rotation car l'huile fuyait à travers le moteur plutôt que de le faire tourner.
