No. J4330 Separator with No.

J4214 6 Ton slotted Crossarm Puller—Used to

remove an electric motor commutator. The

smallest of separators (size #0) has diagonally

positioned threaded holes to accommodate

size 5/16-18UNC cap screws—(Not included

in the J4214 set).

No. J4333 Separator with No.

J4232E 10 Ton Adjustable Jaw Puller—Used to

remove the rear bearing from an output shaft.

Thin, tapered separator edges fit behind bear-

ings when space is too limited for puller jaws.

No. J4333 Separator with No.

J4242 Press-N-Pull

™

Puller—Used to remove

the rear bearing from an auxiliary counter-

shaft. Separator plate threaded holes, and

Press-N-Pull

™

leg ends are threaded alike—

with 5/8-18UNF. Hooks up fast for a positive,

safe, non-slip grip.

Proto-Ease

No. J4333A Separator and

Press-N-Pull

™

2-Way Puller with medium and

short legs. Used to press the pinion shaft

out of a differential housing. Separator’s

extra long 13" threaded rods permit

maximum separator plate spread—

sufficient to straddle the differential

housing and match the spread of

Press-N-Pull

™

slide blocks, extended to

their maximum width along the crossarm.

Proto-Ease

™

No. J4332 Separator mounted

on a shop forcing press, beneath a hydraulic

press ram. Used to remove the bearing from

a rear axle. Ram forces axle down through

the separator opening, freeing the bearing.

To protect the bearing and the gear beneath

it the separator is placed so the bearing rests

on the flat side of the separator plates.

CAP SCREW PULLERS

Proto-Ease

™

No. J4214 6 ton slotted crossarm

puller is used at top left to pull a gear from a

crankshaft. Since both 3/8-16x3 cap screws

are threaded directly into the gear being

pulled, the gear will pull OFF when the forcing

screw’s pressure is applied to the shaft. At

bottom left, the same puller’s cap screws are

anchored on either side of an object being

pushed OUT—in this case, a countershaft,

pressed towards the rear, until it frees the

front bearing.

The larger separator, No. J4333 has 4-corner

symmetrical jacking holes for 5/8-18 cap

screws. Permits separator action where space

does not allow for puller accessories.

Adjustable Jaws also grip separators directly

—mid-point on the threaded rods. For positive

grip, jaws may be angled, tips inboard, and

locked in place, so as to “cradle” the rods.
