Pathfinder Manual Transmission Rebuild Page 4
Transmission Gear Disassembly in my 1994 Nissan Pathfinder 1.
This is incomplete at best. A service manual is essential.
Would I disassemble everything knowing what I know now? NO!!!!
At this point, though, being ignorant, I want to disassemble all the gears to understand how it works.
But first, lets pay some bills:
Removed Reverse coupling sleeve.
Removed Mainshaft Rear SnapRing.
Removed counter gear rear SnapRing.
Removed mainshaft C rings and holder.
Removed counter gear rear bearing.
Removed reverse idler gear, pin bearing, and thrust washers.
With the counter gear rear bearing out of the way,
these came off easily.
Note orientation of washers.
Pulled Mainshaft rear end bearing.
This step only for 2wd.
Pulled reverse main gear, mainshaft spacer, and reverse syncro hub all at once.
I had to cut some threaded rod to extend the reach of this puller.
Needle bearings are in there too.
Pulled reverse counter gear.
I had to get a smaller bearing splitter to fit in here.
Removed overdrive coupling sleeve and baulk ring.
The whole syncro assembly spilled apart here.
All those clips scattered onto the dusty, gritty, garage floor.
Pulled reverse gear bushing and speedometer gear.
Needed 2 hammers and WD40 to get this thing off.
Bent the splitter bolts, dinged the gear.
Had to file the reverse gear smooth before reasembly.
Pulled overdrive counter gear and reverse cone.
Reverse idler shaft comes out. Don't drop it. Onto the dirty cement floor.
Pin bearings come off.
Pressed the shafts out. Alternating. PITA.
Used 2x4 cut to length so I wouldn't have to keep changing the height of the adapter plate.
1st gear washer and steel ball.
I remove 1st gear and needle bearing, and the syncro falls apart.
Here's the adapter plate and counter shaft,
the main shaft with 1st syncro exploded,
and the input shaft with its syncro exploded.
And then I went ahead and got the counter shaft
the rest of the way out of the adapter plate.
- Next I sold out to make 02¢
so I can fulfill my lifelong dream of owning a 1986 944 with blown head gaskets.
But no minivans!
- Then I finished my beer.
