Wanted to ask if Tech Wiki shows how to identify internal parts of my 5 speed transmission. Ready to put this back together and make sure I place everything in the right order.

Yes, their are parts diagrams showing the order of each part

see 60-Series Transmission Parts

FS5W60A

So it looks like the synchronizer coupling sleeves are interchangeable. The synchronizer hubs are different for 1st/2nd and 3rd/4th. Any way to identify the difference between these two? And no markings or stamp on the gears. Any way to identify the difference between the gears?

According to the Nissan rebuild manual, gears are as follows:
1st-32230
2nd-32264M
3rd-slides on the front of the Main Shaft (not identified below)
4th-??
OD (5th)-32340
Reverse-32245

Where is 4th??

4th is direct drive, so there is no gear

Quote:In the diagram:
* 32601 32601-H7301 HUB-SYNCHRONIZER B
* 32601A 32601-H7300 HUB-SYNCHRONIZER 1ST & 2ND
* 32605B 32601-H9000 HUB-SYNCHRONIZER 3RD & 4TH

Note that 32601A, 32264M, etc. are the diagram markers (not part numbers), so it depends on which diagram you are looking at

I do not know how to tell them apart

In the wiki article are photos along with the two diagrams, and all the PNs. H73 parts are designed for the 4-speeds, and the H90 parts are designed for the 60L 5-speed

This is captioned as a 60A "1-2 hub" in the article. Let me see if I can find a photo of the other hubs

Ok thanks. So main drive gear is 4th gear. Makes sense. Tech Wiki has better images of the gears for the FS5W60L. First time doing a rebuild on a gearbox and fairly straightforward with the rebuild manual and this site. Just making sure I put everything in the right place. All the gears are in excellent shape and cleaned up well. Will post pictures later. There is a hex nut that has tabs that are used to keep this nut in place. The locking tabs don't look too good. Is there a replacement or do I use red loctite so that it doesn't back out?

Well you can solve that problem - take photos of your gears as you assemble it, and post them here

I wasn't able to find a good photo of the three hubs, only the 1-2 hub

The main drive gear is involved in "4th", but is not 4th gear, rather the main drive gear drives the cluster shaft gear. 4th "gear" is actually the input shaft locked to the main shaft, so the input to output ratio is 1:1. The two key parts are the 3-4 Synchro Hub which is splined to the Main shaft (output shaft) and the Main drive gear which is locked to the input shaft. When the box is in 4th, torque is not transmitted via gears

Quote:Are you referring to the 5th gear bolt?

5th gear bolts to the end of cluster shaft







Yes, a new nut should be purchased from Nissan (it is not reusabled), part number 32225-H9700

Yes that is it. Buy it from a Nissan dealer? Or aftermarket like rockauto?
