Pinion gear How to install pawl for pinion gear

Replacing the pinion bearing in a 2004 BA Falcon Ute can be a complex and challenging task. Here are the general steps to follow:

1. First, raise the rear of the vehicle securely on jack stands and remove the driveshaft from the rear differential.
2. Drain the gear oil from the differential and remove the rear cover.
3. Remove the retaining bolt from the pinion yoke, and use a puller to remove the yoke from the pinion shaft.
4. Use a suitable tool to remove the pinion nut and washer.
5. Mark the location of the pinion flange relative to the pinion shaft to maintain proper gear mesh alignment when reassembling.
6. Carefully remove the pinion flange from the pinion shaft.
7. Use a bearing puller tool to remove the old pinion bearing from the pinion housing.
8. Install a new pinion bearing onto the pinion shaft using a bearing installation tool.
9. Reassemble the pinion flange, washer, and nut onto the pinion shaft.
10. Use a torque wrench to tighten the pinion nut to the proper torque specification.
11. Reinstall the rear cover and refill the differential with the recommended gear oil.
12. Reinstall the driveshaft, making sure to properly align the yoke to the pinion flange.
13. Lower the vehicle off the jack stands and test drive to ensure proper operation.

the pawls are positioned so that when the wheels rotate in a forward direction they lock up the pinion and drive the cutter blades ,
they release when the mower is pulled backwards
as for grease , if it had none then none is what is used
If it had grease then a water resistant bearing grease would be prefered

Pawl for yr and make

Try it in all the timer cycles. If it still does it then your transmission might need to be inspected. It is a simple design. Remove the agitator and then yank out the tranny. Remove the clutch and transmission cover. Inspect the main drive gear and the spin pawl beneath it.The main drive gear show in this 30 sec video is plastic (click on the link). The new gear comes with a matching pinion for around 75 bucks. More HERE

This washer is easy as heck to repair. Don't be scared to repair this washer.
You could have a broken brake cam driver. To inspect it you remove the agitator and drop the Tranny. Hay you already had the motor and pump off there so 4 more bolts (3 for the tranny and 1 for the agitator) Slide out the tranny and check the brake cam actuator. The little ear on it breaks off and won't release the brake. The part is held with a small easy to remove C clip. The next thing to do is remove the clutch and tranny cover. Inspect the main drive gear and pinion.
If that seems to be good remove the main drive gear and look for a smashed down spin pawl.Under that main drive gear is 3 spin bosses. over time the spin pawl takes a beating catching the boss as the neutral pack pauses from pump out to spin. This is the flip side of the main drive gear. Note the 3 notches. These are claeed bosses. Older model washers would spin and drain at the same time. Newer washers will allow the water to be pumped out first by keeping the spin pawl in check. A built-in pause allows the cent force to toss out the spin pawl where is can catch a boss and take off like Moody's goose in a tailwind. Nothing is hard about repairing this washer.

First, make sure you've got the oil pump drive gear and the pinion on the pinion shaft of the crank and the nut properly torqued. Identify the cams. You should have a "1W", "2W", "3W" and a "4W". "1W" is the rear exhaust and "2W" is the rear intake. "3W" is front intake and "4W" is front exhaust. They go into the engine cases in order 1W in rear, next 2W over the pinion gear, 3W in front of the pinion gear, and 4W all the way to the front of the engine.

Install the "1W" cam. Then install the "3W" and the "4W" cam with the timing marks aligned. Now position the pinion gear with the timing mark straight up and lock the crank. Now, you must install the "2W" cam last making sure that the three timing marks are aligned with the pinion gear, the "1W" cam, and the "3W" cam.

If you can't figure it out, contact me directly at [email protected] and I'll send you a picture.

Good Luck

Rear wheel drives like this have pinion gears with rachet pawls that allow them to go backwards freely while locking when the transmission drives them.

You need to take off your rear wheels and carefully remove the pawls. They look like little squareish metal shaft keys with springs under them. You should notice that the keys or pawls are covered in what looks like grease.....which is actually worm metal from the pinion gear and oil mixed together to form this pastey greasey substance. Clean all that stuff off and lightly oil *( light oil...3 in 1 kind of oil) and reassemble.

You should hear the nice clean clicking of the rachet pawls as you roll backwards again!

Good luck and be careful!

They are two totally different pins with different jobs. The carrier pin holds the differential pinion gears sometime called the spider gears in place by pinning their shaft to the differential case. The park pin secures the park pawl to the transaxle case. Neither pin can be changed without removing the transaxle and disassembling it to get to the pins. They are both in the bottom end of the transaxle case on most automatic transaxles.

here is a diagram on how to replace the front pinion seal.
please do not forget to rate and comment about your experience with fixya.

1. Before servicing the vehicle, please familiarize yourself with safety procedures.
   
2. Remove both half shafts.
   
3. Mark propeller shaft and pinion flange for installation reference.
   
4. Remove front propeller shaft.
   
5. Rotate pinion gear three to four times, to verify pinion rotates smoothly.
   
6. Record pinion flange rotating torque with an inch pound torque wrench for installation reference.
   
7. Hold flange with Holder 6719 and four bolts and washers.
   
8. Remove pinion nut.
   
9. Remove flange with Remover C-452.
   
10. Remove pinion seal with a pry tool.
    Removing the companion flange
    Measuring pinion rotating torque
    Pinion seal installer
    Tightening the pinion nut
    

To install:

1. Apply a light coating of gear lubricant on the lip of pinion seal.
   
2. Install seal with Installer C-3972-A and Handle C-4171.
   
3. Install pinion flange onto the pinion with Installer C-3718 and holder.
   
4. Hold pinion flange with Holder 6719A.
   
5. Install new pinion nut and tighten nut until there is zero bearing end-play.
   
   CAUTION Do not exceed the minimum tightening torque when installing the companion flange at this point. Damage to the collapsible spacer or bearings may result.
   
6. Tighten pinion nut to 271 Nm (200 ft. lbs.).
   
   CAUTION Never loosen pinion nut to decrease pinion bearing rotating torque and never exceed specified preload torque. If preload torque or rotating torque is exceeded a new collapsible spacer must be installed.
   
7. Record pinion flange rotating torque, with a torque wrench. Rotating torque should be equal to the reading recorded during removal plus an additional 0.56 Nm (5 inch lbs.).
   
8. If rotating torque is low, tighten pinion nut in 6.8 Nm (5 ft. lbs.) increments until rotating torque is achieved.
   
   CAUTION If maximum tightening torque is reached prior to reaching the required rotating torque, the collapsible spacer may have been damaged. Replace the collapsible spacer.
   
9. Install propeller shaft with reference marks aligned.
   
10. Install half shafts.
    

The number Jakeyjones gave is the customer service number. Call it and describe your problem.

As for the gear, I had the same issue. I called customer service and was told that there was a supplier material issue that caused some gears made last year to break more easily than they are supposed to. They are sending me 2 new pinion gears completely free of charge. These are the black plastic gears that engage against the orange wheels to make the blades spin. Make sure you don't lose the pawls (metal rectangular pins that go through the shaft to engage the pinion gears).

I called at noon eastern time today. The woman I spoke with was very helpful and knew exactly what parts to give me.
