How does the pin that holds the yoke come out. I have tried knocking it out with no luck. I also can't seem to find any retainer holding the pin in.

Well put on engine stand remove front wheel then mark yokes and fork alignment with marker pen undo retaining clamps on yokes if your forks are upside down ones then undo top cover s then there should be a bolt that holds the inner leg to the fork sleeve once u have removed fork leg remove inner leg from sleeve then you will be able to see the retaining clip inside the sleeve remove this then using a large flat screwdriver get under rubber seal and prize out they are not always easy once done replace with new seal reassemble refill FORK OIL !!! THEN reassemble forks to bike job done

The feeder pin used by hitachi has a shoulder on one side and a rubber washer /retainer on the other. There is only one groove and the retainer fills the groove and if the correct pin and spring, no extra room to fit an exstra retainer unless the shoulder is worn so bad that the pin is falling thru the plunger. I have seen a lot of creative ways that owners use to hold the pin in place due to lost rubber retainer or lost pin. I also see many guns that have installed a retainer pin from porter cable which has two grooves (one on each side of the pin and no shoulder ). Porter cable pin works fine and fits perfect. Good luck

Leak around trigger could be trigger valve internal orings or orings on the outside of the trigger valve making contact against the body of the gun. Spray soapy water to determine where the air is leaking from. If air is leaking around the outside of the valve, most likely the orings were cut upon installation of the valve. If leaking from internal valve, most likely worn or broken oring; easy to fix if you have a source for orings.

To remove the trigger valve for service or inspection (take close-up photo of trigger area for reference ):
disconnect airline, remove nails, remove trigger retainer pin, remove trigger, remove roll pin /s holding trigger valve in place (use 3mm punch to remove retainer roll pins which are located in the body of the gun just above the trigger valve). With retainer pin/s removed and with gloved hand (under trigger valve), apply air pressure to gun to blow out the trigger valve (use lower pressure to push out trigger valve because it could come out with force.). With trigger valve in hand notice that there are two slots or groove cut neer top of the valve where the retainer pins rest, you will need to reinstall valve into body with slots aligned to retainer pins. Remove retainer pins holding trigger together to pull out internal valve. Good luck and post again if your have other question about the trigger valve.

You need to take off the Diff cover and you will see a pin in the middle. you need to take out the screw that holds this pin. BEFORE you do that spin the diff around to where the pin will come out and you can get to the screw as well. DO NOT spin the diff any more with the pin out put it back in and then spin if needed.

Anyways, After the pin is out go to the wheel at the end of the axle and kick it towards the middle of the truck. You might need to whack it with a BFH but usually it goes on in. You will see a C shaped retainer This is what holds the axle in. You want to remember where it was so make sure you look. Also try to put it back with the worn side int he same orientation. remove that C retainer and you can pull the axle right out.

Installation is the reverse of what you just did.
If the C retainer not put back in exactly right the Pin will never go back in as well so good to know if you feel like it isn't right. if you have a doubt knock the axle back in and reset.

Hope this helps!

Lift the rear end of the Explorer with a floor jack. Place jack stands underneath the rear axle, by the leaf spring perches and lower the Explorer onto the stands. Pull the floor jack out of the way. mark both ends of the shaft for reinstalation.

2

Crawl under the rear end and unbolt the universal joint retaining straps from the rear differential yoke.

3

Pull the drive shaft and universal joint away from the rear differential yoke by hand.

4

Remove the retaining rings that hold the universal joint into the drive shaft with needle-nose pliers.

5

Support the end of the drive shaft on a jack stand and place the socket extension against the universal joint cap in the drive shaft yoke. Tap the socket extension with the dead blow hammer until the universal joint cap comes out of the yoke.

6

Clean the sockets in the drive shaft yoke with the tip of a pocket screwdriver to remove any built up road dirt or other gunk.

7

Remove two of the caps from the opposite ends of the replacement universal joint. Be careful to keep the bearings in the caps.

8

Position the replacement universal joint in the drive shaft yoke and put the cap on the outside. Use the socket extension and dead blow hammer to tap the cap through the yoke far enough to expose the retaining ring groove. Put the retaining ring on that side with the needle-nose pliers. Repeat this for the other cap.

9

Move the drive shaft back up to the differential yoke, line up the new universal joint with the differential yoke and reinstall the universal joint retaining straps with the wrench. Lower the rear end off the jack stands with the floor jack.

put flat pan under the housing remove the bolts holding the cover usually 10 or 12 (1/2 or #12 metric) bolts? allow the rear end grease to drain... then scape off the old gasket clean with brake cleaner spray install either new gasket or form one with oil resistant silicone put the cover back on , dont refill the fliud for at least 12 hours if using silicone. Also check the front driveshaft rear end yoke seal....they sometimes leak making the illusion of a rear end pan cover leak...if that is leaking you remove the shaft carefully...remove the large yoke retaining nut, replace the press in seal...be sure retaining yoke nut is properly torqued when reinstalling .

It will need to be pressed out.

Disassembly Procedure
Notice: Never clamp propeller shaft tubing in a vise. Clamping could dent or deform the tube causing an imbalance or unsafe condition. Always
clamp on one of the yokes and support the shaft horizontally. Avoid damaging the slip yoke sealing surface. Nicks may damage the bushing or cut
the lip seal.
1. Support the propeller shaft in a line horizontal with the table of a press.
2. Mark the propeller shaft as to which end is the transmission end and which end goes to the rear axle.
3. Place the universal joint so that the lower ear of the yoke is supported on a 30 mm (1 1/8 inch) socket.
4. In order to shear the plastic retaining ring on the bearing cup, place J 9522-3 on the open horizontal bearing cups. Press the lower bearing cup out
of the yoke ear.
5. If you do not completely remove the bearing cup, lift the cross and insert J 9522-5 between the seal and the bearing cup you are removing.
Continue to press the bearing cup out of the yoke.
6. Rotate the propeller shaft. Press the opposite bearing cup out of the yoke.
7. Mark the orientation of the slip yoke to the tube for proper reassembly.
8. Remove the cross from the yoke.
9. Remove the remaining universal joint parts from the yoke. If you are replacing the front universal joint, remove the bearing cups in the slip yoke
in the same manner.
10. Inspect the retaining ring grooves for plastic.
11. Inspect the bearing cup bores in the yoke ears for burrs or imperfections.
12. Clean the remains of the sheared plastic bearing retainers from the grooves in the yoke.
13. The sheared plastic may prevent the bearing cups from pressing into place and thus prevent the bearing retainers from properly seating.
Assembly Procedure
1. Remove the bearing cups from the universal joint.
2. Assemble 1 bearing cup part way into 1 side of the yoke.
3. Turn the yoke ear toward the bottom.
4. Assemble the cross into the yoke so the trunnion seats freely into the bearing cup.
5. With the trunnion seated in the bearing cup, press the bearing cup into the yoke until the bearing cup is flush with the yoke ear.
6. Assemble the opposite bearing cup part way into the yoke ear.
7. Ensure that the trunnions start straight and true into both bearing cups.
8. Press the opposite bearing cup into the yoke ear while working the cross all the time in order to inspect for a free unbinding movement of the
trunnions in the bearing cups.
Important: If there seems to be a hang-up or binding, stop pressing, and inspect the needle bearings for misalignment in the bearing cup.
9. Press the bearing cup into the yoke until the bearing retainer groove clears the inside of the yoke.
10. Assemble the bearing retainer in the retainer groove.
11. Continue pressing until you can snap both retainers into place.
12. If seating the retainer is difficult, spring the yoke slightly with a firm blow from a dead blow hammer.
13. It may be necessary to lubricate the snap ring with a slight amount of chassis grease so the snap ring seats in the bearing cup groove.
