5th Gear Bearing & Sleeve Update Kit See
detailed discussion |
1985-1992 |
$46.62
|
The Mitsubishi 5 speed used
in the Ford Ranger from 1985 to 1992 has had a notorius problem with the 5th gear
bearing sleeve wearing into the 5th/reverse synchronizer hub. This problem further
has cause the failure of the 5th gear on the mainshaft, causing the 5th gear to seize
to the 5th/reverse hub and then break.
The problem is inherent, because the mating-surface area of the 5th gear bearing
sleeve is too small. Although pressures against the hub are amplified while the transmission
is a high operating temperatures, they decrease significantly when the transmission
cools to ambient temperature. This continual pattern causes the sleeve to work loose
against the 5th/reverse synchronizer hub and then begins to wear into the splined
area of the hub.
As this wears, the preset factory clearances for end play are diminished to the point
that the 5th gear on the mainshaft begines to heat the hub and scuffing begins to
appear. If this situation is not corrected, it will cause the 5th gear to seize to
the hub, breaking the gear teeth.
Given the size and load characteristics of the 5th gear, correcting the problem by
simply changing the gear design is next to impossible. Now available is a unique
answer to this nagging problem. Not only is it simple but also it is very inexpensive
to install. The entire kit includes only tow pieces, a newly designed caged bearing
and bearing sleeve (see Figure 1). Further design change directs the radial pressure
from the gear to a more specified area on the bearing sleeve. |

Installation
During inspection for a repair or re-build of the Mitsubishi-built 5 speed, closely
examine the area where the 5th gear bearing sleeve contacts the 5th/reverse synchronizer
hub. If there is any noticeable wear, replace the 5th/reverse synchronizer hub. Also
compare old design 5th needle bearing sleeve to new design (see Figure 1), and after
inspection install new design 5th bearing sleeve with flange against 5th/reverse
synchronizer hub (see Figure 2). Figue 1 also shows the old design.
Apply assembly lube on all mating thrust surfaces and assemble remainder of main
shaft. Torque mainshaft nut to 181-195 ft. lbs. Check that the .006" - .010"
clearance is maintained between the 5th gear on the mainshaft and the 5th gear thrust
washer (see Figure1).
This installation will end you problems of poor th gear end clearance on the Mitsubish-built
rear wheel drive 5 speed. The update kit is approved by the OEM manufacture.
