Has anyone replaced clutch plate 313/310/371? They are similar machiches. I am attempting to change four clutch plates, belly of machine is open, two clutches on each side(forward reverse). I will release inner and outer chains and pull apart clutch. This machine has electric slow /high speed clutch that is rigged to toggle switch on control arm(not this way from factory). Will drain oil from pan that chain drive and clutches sit in and replace with new oil. I have picture and will post of 313 chain drive system.
 
Parking brake not working on 313 bobcat. which position is on? Its on left side of machine when sitting in it. Guy I purchased from said it was always down. Is down off position for 313 bobcat parking brake?

Help, I can't figure out how to pop out clutch. Looks like a bolt runs through the gears from outside where the clutch adjuster is. I cannot figure out how to get this out. I keep turning the nut counter clockwise but just keeps turning. Help.

Can you try and get someone to hold a lever to put force on the cluth to maybe get the nut off? or am i wrong on how its fitted together?
This setup is totally alien to me, so i'm just guessing, sorry.

All four clutches replaced, turns on a dime. Next going to replace filters and fluids. Getting to know this machine is a learning curve, but not too bad. Would like to talk to someone who has 310/313/371.

It really is amazing how much you will pick up when doing your own work, and even when you need to figure out how to do the work. I know i learnt a LOT from my old 731 when i was doing repairs.

How did you end up getting the clutches out? I have removed the shaft that goes all the way through, but can't seem the get the clutches out from there.

Hello Piep0, Did you ever get your clutches out? I just saw this thread tonight and just joined the SkidSteer Forum tonight so I could ask a question. I have a 310 also and it is difficult to make left turns unless I'm on dirt or snow. It does not seem to have the power to turn on pavement. Everything else works fine. I think I will try to get new clutches from Bobcat and try an install since the previous gentleman said his machine was like new after the install. I know this thread is old but thought I would post here first. Thank you, Mogger

Please try to take pics and update us as you go. That way everyone can learn. Us mods will help with posting pics if needed. I had a 371 but never did the clutches. They are a cheap little home owner machine though and simple to work on.

We did get the clutches out. I will explain how down below. If you are having problems turning it's possible that you just need to adjust the clutches on that side. Does it have the same problem whether you are trying to turn forward or backwards. There is a separate clutch on each side for each direction. If one of the levers moves really far forward or backward, you might be able to fix that by adjusting that clutch. (This can be done without opening anything up and is quite a bit easier than replacing the clutch) I think the manual says the top of the lever should go about 3" in either direction when properly adjusted. To actually remove the clutches: You must remove pretty much all of the chains on the side you are replacing. Then you will have to take off a wheel to be able to get the shaft going through the clutches out. The shaft is a single shaft but has a nut on both sides. If you put a wrench on both nuts, when of the sides will come loose and then you can pull the shaft out. Next comes the part we had trouble with, which was getting the actual clutch out. (They were in there really tight) We ended up using a come along attached to the rollcage to pull the clutch out. It should be pretty much reverse to put it back in. If you have any other questions let me know. We had to fix the bearings in one of the big jackshaft sprockets in the very back, so we had almost everything out.

Make sure to remove the square adjusting plates on the outside of the frame before trying to pull the clutch packs. The squares have keys that interlock with the clutch and allow adjustment. I used a piece of 1/2-13 threaded rod with coupling nuts on each end to spread the frame apart near the clutch shaft holes. Everything comes out (and goes back in) very easy that way. Working the unit in high gear is very hard on the internal drivetrain. I've had both needle bearings go bad in my large rear sprockets. Replaced both with bronze bushings (drilled holes for oil) and haven't had any issues since. Now we only use high gear for moving snow. Low gear is slow, but it's amazing what the little machines can push.

I have a 310. I think the clutch set up is the same. To adjust the clutches, do you loosen the small nut crank the 1" 5/16" nut? I've been staring at the manual for hours.
