What can I do to get the air out of a 5400 JD, I removed the loader and installed a new clutch and pressure plate, I got tractor back together and have no hyds or power steering. It acts as if it has air in system nothing is working except the PTO and transmisson. Does the liness on the back have to be changed some how I have no books.

Question edited for clarity and typos.

The link should explain installation and removal of both.

Clutch disk is rusted to the pressure plate.

Remove transaxle. Remove clutch pressure plate. Remove clutch plate. Inspect the flywheel for damage and resurface or replace as necessary. Replace pilot and throwout bearings. Install new clutch plate. Install new pressure plate. Re-install transaxle.

The biggest problem here is the alignment of all the parts. Firstly the clutch plate spline and the spicket shaft bearing in the flywheel have to be perfectly aligned, many clutch kits now supply the correct alignment tool as part of the service. Then the spicket shaft has to go into the clutch plate and the spicket shaft bearing perfectly straight, if all parts are aligned, the two halves of the tractor should slide into place easily. If you did not get an alignment tool, you can make one up using a shaft that fits into the spicket shaft bearing and then build up the thickness to fit into the clutch spline with masking tape. Using this method you will have to check your assembly by eye to ensure perfect alignment.

My son and I took apart the toy as we have the same problem with ours. The green terminal on the motor moves when we apply pressure to it and the motor speeds up considerably. It appears that a weak or bad terminal is the cause of loss of power. We are not sure how to maintain the pressure on this terminal.

We are going to put it back together and see if it works.

In order to remove the clutch from your bike, you must have a special tool. You'll need H-D #34761 in order to remove the snap ring holding the clutch together.

Disconnect the battery, drain the primary, and remove the primary cover. Once you have the primary cover off, you can remove the nut from the compensator sprocket at the engine end of the primary chain.

Install the H-D 34761 or equivalent tool and compress the clutch spring. Remove the snap ring and then back off on the tool to release the pressure on the clutch spring. Once the pressure has been removed, remove the adjusting screw assembly, the outer clutch spring seats, the clutch spring, the inner clutch spring seat, and the pressure plate.

Then you can disassemble the rest of the clutch. Remove the remove the four friction plates and three drive plates. Then you can remove the spring plate and the remaining plates after that. Remove the snap ring that holds the clutch assembly onto the transmission clutch gear and remove the inner and outer clutch shells, the primary chain, and the engine sprocket as a group.

For this job, I would recommend that you purchase a service manual. It's has pictures that show you what you're dealing with and in this case, a picture is truly worth a thousand words.

Good Luck

Jack up car unbolt axles, unbolt transmission, remove wires and other attachments. Remove transmission. Take out throwout bearing clutch and pressure plate, replace and put back together.

First you go to mechanics school so you know the basics on safety etc.
Now you can block the car up in the air and remove the driveline and all electrical and mechanical connections from the transmission. Next support the engine while you unbolt the transmission from the engine. using your transmission jack slide the transmission back far enough to get easy access to the pressure plate. remove the bolts holding the pressure plate in place and remove the old clutch. Of course you got a new clutch, pressure plate and throwout bearing right? you may need a pocket bearing for the tip of the transmission input shaft as well. installing is the reverse of removing though you will have to consult the manual for torque specifications and you will need to make sure the clutch is centered before you bolt the pressure plate back down.
OR you could take it to a transmission shop and have them do it for a couple hundred bucks.,

REMOVAL:

1. Lift clutch pedal to uppermost position to disengage clutch and brake pedal pivot shaft.
2. Push clutch and brake pedal pivot shaft forward and unhook clutch release lever cable from clutch and brake pedal pivot shaft and allow it to slowly swing rearward.
3. Raise and support vehicle.
4. Remove clutch release lever dust shield.
5. Disconnect clutch release lever cable from clutch release shaft.
6. Remove retaining clip, then clutch release lever cable from flywheel housing.
7. Remove starter motor from flywheel housing, then engine rear plate to front lower flywheel housing bolts.
8. Remove transmission.
9. Remove flywheel housing back just far enough to clear clutch pressure plate, then remove housing.
10. Remove clutch release shaft from flywheel housing by pulling it through window in flywheel housing until retainer spring disengages from pivot.
11. Remove clutch release hub and bearing from clutch release shaft.
12. Loosen six clutch pressure plate bolts evenly to release spring tension gradually and avoid distorting clutch pressure plate. If same clutch pressure plate is to be installed, mark plate and flywheel so pressure plate can be installed in its original position.
13. Remove clutch pressure plate and clutch disc from flywheel.

INSTALLATION:

1. Position clutch disc and pressure plate assembly on flywheel, noting following:
   1. Three flywheel housing to block dowels on flywheel must be properly aligned with clutch pressure plate.
   2. Bent, damaged or missing flywheel housing to block dowels must be replaced.
   3. tart clutch pressure plate bolts but do not tighten.
   4. Avoid touching clutch disc face, dropping parts or contaminating parts with oil or grease.
   5. Align clutch disc using suitable alignment tool inserted in pilot bearing.
   6. To avoid clutch pressure plate distortion, alternately tighten bolts a few turns at a time, until they are all tight, then tighten to specifications.
   
   
2. Install transmission to flywheel housing.
3. Install engine rear plate to flywheel front lower housing bolts, then connect clutch release cable to flywheel housing and connect retaining clip.
4. Connect clutch release lever cable to clutch release shaft, then install clutch release lever dust shield.
5. Install starter motor.
6. Lower vehicle, then install clutch release lever cable as follows:
   1. Lift clutch pedal to disengage clutch and brake pedal pivot shaft.
   2. Push clutch and brake pedal pivot shaft forward and hook end of clutch release lever cable over rear of clutch and brake pedal pivot shaft.
   
   
7. Cycle clutch pedal several times to adjust clutch release lever cable

Buy clutch cover gasket
Unhook clutch cable at clutch cover
Remove clutch cover
Remove 5 clutch spring bolts
Remove springs
Remove pressure plate
Remove plates and disc noticing order
Replace with new plates/disc in same order (after soaking in oil for at least a few hours, over night would be better.
Put everthing back together in order of removal.
