Hudson Jet Essential Service Tools
This special adapter has been designed to permit use of the J 2241-A Puller on Jet differential side bearings. The pilot of the adapter fits into the differential case hub thus providing a surface for the end of the puller screw to exert pressure against.

1. J 5365 Rear Pinion Bearing Cone Remover
10. J 5223-50 Pinion Setting Gauge Adaptor
To facilitate removal of the rear pinion bearing cone without damage to either the bearing cage or pinion, use the J 5365 Remover with an arbor press. With the tool in place, as shown, the shaft can then be pressed or driven out of the bearing.

J 5223-50
The new gauge block and mounting discs of this Adapter Set, when used with the J 5223 Pinion Setting Gauge, provide the mechanic with a completely accurate means of setting the drive pinion when reassembling the differential.
2. J 5372 Rear Axle Spreader
According to Hudson Service Merchandiser Vol. 5, No. 10, October 1953, some reports [were] received from the field to the effect that the part #J-5223-50 Pinion Setting Gauge Adaptor, included in the Jet Essential Service Tool order, will not close up sufficiently for use in checking the distance between the rear end of the drive pinion and the center of the axle, on Jet Models equipped with the 4.1 ratio axle.

Pinion Setting Gauge Adaptor Revision

This condition can be easily rectified by drilling out the small stop in (A-Figure above), removing plunger and grinding sufficient metal off small end (B) to permit gauge to close up to the dimension required (2.250") for checking the 4.1 ratio drive pinion.

The stop pin need not be replaced since the thumb locking screw will retain the plunger.
J 5372

J 5372
In order to remove or install the differential assembly it is necessary to spread the differential housing to provide for compensation for the preload or side press between the bearing cups and housing. J 5372 is the tool required to perform this operation.
3. J 883-10 Valve Guide Replacer Pilot
(Used with J 883-B Set)
Proper valve guide installation on jet engines is assured when this essential replacer pilot is used in conjunction with J 883-B Valve Guide Installer Set. Calibration of the pilot insured that the guides aredriven to the proper depth.

4. J 5490 Clutch Finger Adjusting Gauge
11. J 2587-A Transmission Mainshaft Endplay Guide
J 5490

J 5490
The J 5490 gauge plate is the same thickness as the clutch plate and the hub is machined to correct finger height. To use, replace driven plate with gauge so raised lands are directly under fingers. Bolt cover on. Place finger height gauge on hub. Properly adjusted fingers will just touch this gauge.
J 2587-A

J 2587_A
This special tool slips over the front planet carrier assembly spline and the internal threads engage in the threaded portion of the mainshaft. Thus, when mainshaft endplay is checked the two shafts will be held in their proper position, and a quick, accurate check is assured.
5. J 5366 Pinion Shaft Oil Seal Installer
This special tool provides an easy and positive means of installing the pinion shaft oil seal. To use, pilot the tool or the pinion shaft oil seal. To use, pilot the tool or the pinion shaft with the tool flange contacting the outer rim of the seal and tap the tool lightly as shown, to install the seal.
J 5366

J 5366
Proper installation of the rear axle shaft inner oil seal can be accomplished with speed and ease when J 5370 is used with driver handle J 872-5 as shown. The pilot of the tool is designed to assure correct seal placement in the axle shaft.

This dual-purpose tool is sued to replace the clutch pilot bearing without damaging or distorting it and it's also employed to align and pilot bearing so transmission can be installed in true line with clutch.
J 5369

J 5369
This specially designed installation tool provides the mechanic with an efficient means for installing the bearing cone on the rear axle shaft. The tool pilots on the shaft and drives against the bearing cone inner race. The bearing is started in position and driven in place, perfectly aligned and without damage.
