Part III
NOTE: Input shafts lengths vary.
Pre 1995 R150\R151 = 6.5"
1996 up Toyota R series = 7.5"
AX15 = 7.875"
87-92 Turbo Supra R154 = 7.25"
AR5 = 8.2"
MA5 = 8.2"
NV3550 = 7.875"
NV1500 = 8.6"
AX5 = 7.5"
Toyota W series = 6.5"
Toyota G series = 6.5"
Pic 2 Advance Adapters makes an extra long pilot bearing when using a slightly shorter input shaft tranny with a bellhousing that had a longer one. Obviously you can't put the longer input shaft trans into a Toyota bell that had a shorter one. (Unless a spacer is used or the input shaft is swapped. See below.)
The transmissons and bellhousings can be split up into two categories. SHORT SHAFT\SHORT BELL and LONG SHAFT\LONG BELL. They cannot be easily mixed without modifications.
All AX15's, AR5's, MA5's, NV3550's, R154's and Toyota R150's (built after 1996) are LONG SHAFT\LONG BELL. To use one of these in a SHORT SHAFT\SHORT BELL application requires a 1" spacer available from Japanese Auto in Toledo, OH ( http://www.japaneseauto.com/ ), Dellow Automotive or Castlemaine Rod Shop in Australia. Of course, any bellhousing combo one can think of is also available from them...
http://www.dellowauto.com.au/catalog...Automotive.pdf
http://www.rodshop.com.au/
ALL Toyota R150's and R151's built before 1996 are SHORT SHAFT\SHORT BELL. These CANNOT be used in a LONG SHAFT\LONG BELL application or with LONG SHAFT\LONG BELL adapter plates.
Pic 3: Example of a LONG SHAFT transmission hooked up to a SHORT BELL with a Dellow Automotive spacer
The Jeep AX5's 7.5" input shaft does not allow it to be used with the Toyota G and W series bellhousings unless a spacer is fabricated OR the input shaft is swapped between them. (Apparently the short 6.5" G series Toyota input shaft can be made to work in an AX5 case and vice versa). The one exception is shown below.
The Jeep NV1500 has the longest input shaft of the group at 8.6".

Pic 5: All of the small pattern transmissions.

Pic 6: Front bearing covers are interchangeable between the Toyota R series, AX15, MA5, and AR5. NV3550, AX5 and W series are not interchangeable. The 92 and earlier Jeep AX15 front cover is aluminum and takes a hydraulic throwout bearing. The 93 and later AX15 uses an external slave and clutch arm. It's cast iron. The Toyota front cover has a shorter nose of a smaller diameter and is also cast iron.
So... there's no shortage of parts for these gearboxes. Any good shop can rebuild them and they are still not that expensive.

For those Jeep gents that have broken AX5's laying around, Don't ditch the bellhousing. It may be used in a Toyota application and can bolt up any GM 60 degree engine (3.4/3.1/2.8 Chevy V6, Buick 3800 V6, Isuzu 3.2/3.5 V6, etc....) to the Toyota G series and W series tranismissions.
Pic 1 is a Toyota W58 out of a Supra hooked up to an AX5 bellhousing.
Pic 2 shows the AX5 bell planted up to a Chevy Camaro 3.4L V6.
Pic 3 For this to work with the AX5 bell, you'd need the thick (heavy) flywheel from a Camaro/Firebird. It places the clutch disk back far enough to completely engage the splines on the short W/G series input shaft. That's got to be at least 1 3/4" from the back of the block to the front face of the flywheel. The S10 flywheel is shorter (more narrow) and won't work.
Pic 4 is a bellhousing also with the GM 60 degree pattern from the 96-00 Dodge Dakota 2.5L hooked up nicely to an R154 5-speed out 87-92 Toyota Turbo Supra. It also requires the use of the Camaro 3.4L V6 flywheel.
Note: This information applies only to the Rear Wheel Drive versions of the 2.8\3.1\3.4L V6. They have the starter on the passenger side which clears the bellhousing. The Front Wheel Drive versions of these engines, 3100\3400\3500\3900 V6's have the starters on the driver side of the block. That would require either cutting into the bellhousing or finding a way to bolt the starter on the opposite side. Also, FWD flywheels are a different diameter than the RWD flywheels.
