Replacing R32 Manual Gearbox Seals

[adoboy666]

ok, with the r32's as old as they are, at some point will need seals replaced on the manual gearbox.

If your gearbox is somewhat leaking the main culprit will be the old seals which have started to show their age.

Now seals arnt that expensive especially if you get them from a bearing manufacturer as they stock seals for most car gearbox's although they are not genuine but still cheaper.

Nissan Part numbers for the gearbox seals are:

32114-Y4000AU (front gearbox seal) -$4.54

32136-U0100AU (rear gearbox seal) - $8.30

*Prices may vary between nissan dealerships

So either pop down to your local nissan dealer and provide the part numbers or ring up ur local bearing place and ask them if they have them in stock.

Removing and replacing front seal

here is a pic of the seals ( pic 1)

Remove the 5 bolts holding the front cover on(pic 2)

You'll then be able to see the front input shaft bearing and another shafts black bearing.note the shim hanging off, when reinstalling the cover plate put the shim in the corresponding groove in the plate(pic 3)

pic of the bearing shim(pic 4)

Pic of cover plate, note the 2 big circles, the left circle holds the black bearing shim while the right circle contains the front input shaft seal which we will be replacing(pic 5)

flip the cover plate ova and you will see the hole in the protruding shaft, slide a screwdriver through this hole and hammer out the seal(pic 6)

seal is now removed, clean up the cover with degreaser and make sure seal surface is totally clean(pic 7)

oil up the seal and seal surface and push into the hole.

now you will never be able to push a seal in flush with ur own hands a special tool called a bearing drift is needed which is just anything the same size as the seal which is placed on top and hammered to make the seal sit flush without damaging the seal itself(pic 8)

you can use your old seal as a bearing drift, the use of this means the new seal wont get damaged, hammering directly at the new seal will more then likely damage it. Place the old seal on top of the new one and hammer flush.(pic 9)

oil up and place bearing shim into the corresponding circle groove in the cover, oil up the inside of the front seal and front input shaft, making sure the input shaft is clean slide the front cover on and bolt up

removing and replacing rear seal

Here you can see the rear of the gearbox the rear seal surrounds the rear output shaft(pic 10)

To remove grab a flat head screwdriver and pry against the output shaft and the seal should pop out as shown (pic 11)

again clean and oil up seal and seal surface, push new seal in and hammer flush with the old seal as done on the front seal

Done!!!!! - now sitback and enjoy, with peace of mind that ur gearbox wont leak

pleas note depending on front cover gasket condition it may need to be changed, mine was fine so i just left the old one on.
