Bobcat Skid Steer Drive Motor Repair. Weak drive motor low power.
Вставка
- Опубліковано 8 вер 2024
- Bobcat S205 Drive motor repair, symptoms were weak drive on right side, machine would move forward and reverse but did not have enough power to turn with right side. Checked the case drain filter and found seal material in the filter. Removed motor and inspected the Geroler section for damage. No damage found in motor other than bad seals. I go over the process of resealing and checking the motor for damage and proper assembly. This same Eaton motor can be found in many other Bobcat models.

This is by far the best most professional detailed videos i have seen, this guy is a natural
“If your one of those guys that likes to torque shit” hahaha. Great video. Good job explaining everything on the motor!
I had the exact problem with my bobcat 751 (it looks like exactly the same drive motor as well) also did a video about it way back when... The plastic and rubber combo weird seal was totally smashes in bits when i opened the motor up, just like yours. Now all i got is a belt squeel when i try to do some heavy torque work with it. Should try to change out the belts and make sure it has some good tension on it.
I would definitely change out the drive belt and probably the tensioner as well. I have a video on exactly how to do that but I'm sure you are already know how saying is you've rebuilt a drive motor you obviously know what you're doing. Thanks for the comment, let me know if you have any more questions
You do the best videos. Bobcat should be proud of you being one of their master mechanics. And pay you accordingly.
Thanks for a great video. Love to watch you tear down and rebuild motors. I'm a gear head, so i find these vids very relaxing while i learn something new. Thanks again!!!
That was a great video, I learned allot, I never worked on drive motor before, but with your video I am confident that now I can, I just bought a skid steer my self I hope I did not over pay it’s a 1987 model 741 Bob Cat, I was told drive side motor was bad, it had new tires, I payed 5k for it, I am thinking of doing this drive motor rebuild on my channel and I also want to service it and paint it, I am a diesel mechanic and work on Mercedes diesels, but I am hoping I can figure it put on a bobcat 😊 thanks for the video, Btw I subscribed and hit a like 👍
Thank you so much, 5k is a good price if it starts and runs, even if the drive motor is not able to be rebuilt, they are relatively inexpensive.
The best videos on Bobcat repair on UA-cam...by far. Thanks. We have pulled and resealed a few motors with varying results. We sometimes notice that the geroller is loose and some of the pins slide out quite easily. NO scaring or blueing. Is this normal or a sign of wear and time for replacement.
I think my charge pump is also going bad. Left side drive feels weaker and you have to push the sticks way far forward to go wide open. And my belt squeals every time I go to do a rotation.
Great video! Thank you.
Charge pump would maintain pressure in the system but the charge pump is mainly used for lift and tilt and has nothing to do with drive. Drive is controlled by the hydrostatic pumps. First thing I do is change your belt and get proper tension on it and see if that helps.
Looked at the Cardon shaft an splines, rollers and case and rollers slap a seal kit, no deep gives on the plates. after everything’s been clean . It’ll go at-least 5-20k hrs.
Sweet machine
Super videos sir, thank you so much
Really good videos, Thanks for the info. Is there a way to bypass the Boss sys on a 753.
Another awesome video, I like how you set out a nice clean area
Thank you! Cheers!
Good to see a few more bobcat videos recently. They’ve helped me in the past, so thanks for that. My machine was in a real bad way when I first bought it. Have you ever had to repair or replace the bobcat computer/Ecu? My electrical system is rough, in the process of tidying it up, the circuit board in the computer has some bad burn marks. 2003 753 from the Uk.
nice job on that
Thank you for sharing. Your videos are not only extremely informative but they're relaxing to watch. I have two questions: what Milwaukee impact driver do you use and where do you find the breakdown procedure and torque specs?
I get the torque specs from the bobcat service manuals, sometimes a google search will have the specifications listed. As far as the Milwaukee impacts, I use many of them, the 1/2 high torque is awesome, and the 3/8 fuel stubby M12 is a must have.
@@tetradgroup Just bought the stubby LOL. It's fun being able to fix your own equipment.
New to your channel and you do a great job in explaining the process. Thanks and keep it up.
Great video. Any tips on a 2013 S550 with left side getting slower than the right? Also gaining oil in the chain case.
Is this the same drive motor for a300? Thank you for sharing your knowledge!
Thank you
What do you think of this issue. I can rest my heel on lift pedal and it won’t be hard enough to actuate it. But if I curl at the same time, the bucket goes up. Bad block?
Thank you for the video gracias
Always great videos, thanks
Thanks for watching!
I have a 753 Bobcat and I am having trouble the right and left levers are not coordinated and one side has more drive than the other. Is there anything that is obvious to you.
Did film a video of the machine driving around
Great videos. I’m working on a 843 drive motor re-seal. Seeing long lead times on o ring kit. 8-10 weeks. Do you have a better source?
Does the drive motor on both sides spin freely after you take it out, or does the left side not move
Hello bro I'm Miguel from Argentina
I have a T250 hydraulic drive motor the Bering behind the seal was bad do I have to remove the hydraulic pump and have it rebuilt I replaced the Bering and seal and put it back together but it doesn’t feel right when I ran it I can’t find a video on removing the pump if I need to
How did you get all the air out of it when you reinstalled
Is that a 192-0007-003 Eaton (now White Drive)? I handle the customer claims tor them and by far, these are the biggest hitters. Gives me job security lol
I have a 773 and I don't see leaking from my pressure lines. Does the drive motor connect to the chain case behind and could there have been a seal compromised back there ?? I've been running a jack hammer unit on the machine and I'm slowly finding all the loose parts LOL.
Yes hydraulic oil can leak into the chaincase if the motor seals are bad.
Have a s185 and the strangest thing happened today .Both left side wheels locked up and I was unable to steer machine, and it happened a few times.I let the machine sit for about 6 hours and the machine ran perfect like nothing happened.What could that be ?
I'm also looking for a used bobcat. Was wondering if you may be able to tell me how much you paid for this machine? Thanks
👍Again.
What a bad Drive motor seal push fluid into the lower Reservoir chain area and overfill it?
Actually the carrier seal behind the drive motor
Was that an xud9 Puegeot engine you were starting. ??
Nope but I am working on one next week, I'll try to get a video
I have a s185 that has a whine when driving and turning, it quiets a little at higher RPMS, everything works as it should. Could that be the drive motors?
I'm having the same problem with my T250. Did you figure out what your problem was?
What causes the chain case filling up? I have a 763 1998
I have the same issue on 02-753, Losing hydro fluid in main system but not running out except for axle seal.
@howIdidit Do you have the sizes or a place to get the plugs that you put in the hydraulic hoses to plug them when doing a motor rebuild so you dont lose all your fluid and make a mess?
I get my caps and plugs from Amazon.
@@tetradgroup the problem is I dont know what sizes I need.
I would like to try and rebuild my drive motors on the 853 I just purchased. One of them definitely provide more power than the other. Can you tell me where to get the seal kits? I searched Google but did not find anything specific to the 6720886 drive motor.
Bobcat should have them or check loader parts source
@@tetradgroup Thank you, I will check them out. Would you recommend rebuilding the weak side or just go ahead and do them both?
Can you tell me how you diagnosed the problem please?
This machine would only drive in one direction,
All the more reason to use Amsoil!
Need help with my 753F skid steer bobcat it won’t stay running.
Do you think it's electrical or fuel issue?
Hello sir, I am having problems with a bobcat t250. On the advanced display it is showing low charge pressure and getting a lot of feed back in the sticks when trying to push or turning but no codes. The drive belt is new, the tensioner is new, the case drain filter is new and showed no signs of extensive metal coming from either of the drives, there is no hydraulic fluid mixing with gear oil. The hydraulic filters and oil are both new. Is it possible the charge pump is just weak and could be replaced?
I should probably add that the machine has been ran low of fluid by the previous owner. I bought the machine with many leaks and many issues.
Need to verify charge pressure first. Could be low charge pressure or the hydrostatic pumps themselves
@@tetradgroup I will check the charge pressure, thanks! Do you know what charge pressure should be for a 2004 model? I do not have a service manual.
@@tetradgroup ok, charge pressure at idle is right on 300 psi and does not vary much with loader function, at full speed 2400-2500 rpm’s the charge pressure is around 430 and doesn’t vary much with loader functions. As soon as I take off i get resistance in the sticks and it plungers to 200 but recovers and stays in the low 400s as long as I am tracking straight any twists or turns it starts plummeting and will even go as low as 50 pounds but recovers as soon as I let off the sticks.
Do you need to renew all the hydraulic oil? because the plastic?
All the debris is caught in the case drain filter so no need to flush the hydraulic oil.
@@tetradgroup I have a manifold and do not have case drain filters so I am hoping the filter below the fan catches the debris.
Hello I have a bobcat 753, on the right side I have full power in reverse and almost no power going forward just slight movement and surging but no actual power. I reversed the hydraulic hoses on the drive motor so the controls were reversed so pulling backward on lever made it go forward and the problem was still identical even with hoses reversed the forward movement was still weak and still had full power in reverse. This seems like it wouldn’t be a hydrostatic pump issue then. Any suggestions what you think the problem may be?
That is consistent with a bad seal inside the drive motor, should be very similar to this video right here. When that seal goes out usually have power in One direction and not the other
Ok thanks … one more thing I lifted skid steer off the ground so all tires were in the air and that problem side appeared to respond perfectly the wheels would spin forward and back as they should no noises or anything so the problem is only when it’s trying to move the weight of the machine … still seem like it could be a bad seal in drive motor?
@@tedpeacock3945 yep, oil takes path of least resistance, machines off the ground if lower resistance will turn the wheels instead of bypassing the seal then still a motor issue
Would this be similar in a 2002 CAT 262?
Similar but the 262 will have a bigger motor
Hope you can help me - my 1979 730 has no governor on Wisconsin engine I just installed. Arms go up and down quickly at higher rpm, however the machine barely moves forward/backward, sometimes seems to surge and starts bucking, unable to climb even small grade. I parked it against block of concrete - cannot spin tires. Do these sound like symptoms of a weak drive motor? I started convincing myself it's my missing engine governor...
It’s beautiful cause it’s always broken.
I have a T650 and i am hearing a popping noice in the undercarriage area when its cold. Its seems to get better as i use the machine. Can you help? I can send you my number if thats works
A guy is selling a cat 216 and he saids the machine doesn’t move foward or backwards why could be the problem
Does the lift and tilt work? Its odd that both sides would not work at the same time unless the drive coupler is stripped but you would not have lift or tilt either.
@@tetradgroup it does lift and tilt I believe but he says the boom lifts up by itself
यह मोटर अलग से मिल जाएगा और कितने का मिलेगा बताइए सर
