Replacing R32 Manual Gearbox Seals

[adoboy666]

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

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

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.

here is a pic of the seals ( pic 1)

Removing and Replacing front input shaft seal

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 grrove 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, to get it sitting flush take your old seal and place on top of the new seal and hammer flush as shown in the foto, never ever hammer directly onto the seal as you may damage it (pic 8)

placing old seal over new seal to hammer flush, make sure the seals numbers are facing upwards(Pic 9)

Now reassamble in the reverse order making sure you put the bearing shim into the circular groove corresponding to the black bearing again making sure you clean and oil up front input shaft and front seal.Bolt front cover back on.

Removing and replacing rear oil seal

here is a picture of the rear of the gearbox, surrounding the output shaft is the rear seal (pic 10)

grab a flat head screwdriver and lever off the output shaft to pop the seal out (pic 11)

same process goes with the rear seal, clean seal and seal surface, oil the seal and surface up,push seal in and then hammer flush with the old seal.

Thats it Done!!!!

Now sit back and enjoy with the peace of mind your gearbox wont leak.

please note, front cover gasket may need replacing, mine was fine so i didnt have to get a replacement, if you need a gasket ask nissan when you are there and they can get the part number up on their nissan fast computers and order it for you.
