Removing Existing Cutterhead

1. DISCONNECT MACHINE FROM POWER!

Remove jointer fence and cutterhead guard.

2.

3. Remove rear panel and belt guard, then

remove V-belt from pulleys.

Lower both tables to make enough room for

4.

the cutterhead to come out (see Figure 2).

Note: When lowering, make sure that the

fence support does not come in contact with
the cutterhead pulley.

Jointer knives are extremely sharp. You
must remove the jointer knives, or mount
the knives blade side down to avoid the risk
of serious personal injury during the follow­ing steps.

6.

Wearing heavy leather gloves, carefully

remove the cutterhead from the casting (see
Figure 4).

Note: Your cutterhead may have paper shims

stuck to the bearing block or where the bear­ing block rests. These were included at the
factory when they calibrated your cutterhead
to be even with the outfeed table. Your new
cutterhead may or may not need these. If
you see any shims, carefully pull them off
and set them aside for later use—or keep
them with your cutterhead in the event that
you re-install it later. Also, mark the side of
the cutterhead where they were used, so the
future install will go smoothly.

1–

5. Remove hex nut and lock washer on bearing

block stud, as shown in Figure 3, and repeat
on the other side.

T31849 6" V-Helical Cutterhead

Installing V-Helical Cutterhead

Cutterhead inserts are extremely sharp.
Wear heavy leather gloves to avoid the risk
of serious personal injury during the follow­ing steps.

Move straightedge to the other side to deter-

5.

mine if one end of cutterhead body is higher/
lower than the other. (Place feeler gauge
between cutterhead body and straightedge to
determine the height difference.)

If cutterhead is even or within 0.003" with

—

outfeed table from one side to other, skip
to Step 7.

1. DISCONNECT MACHINE FROM POWER!

Install V-helical cutterhead (see Figure 5)

2.

with bearing block studs, lock washers, and
hex nuts included with the Model T31849.

Figure 5. V-helical cutterhead installed.

Tighten cutterhead in place, and ensure pul-

3.

ley set screw is tight.

If cutterhead is over 0.003" from one side

—

to other, go to Step 5.

Loosen hex nuts securing both bearing block

6.

studs, lift V-helical cutterhead slightly, then
place a shim beneath bearing block that
needs to be adjusted.

Note: Use shims from your old cutterhead

if available. If not available, newspaper is
approximately 0.003" thick and will work for
shimming (we don't recommend shimming
more than 0.003" on either side, as this may
affect how the bearing block seats in the
casting).

Repeat Steps 3–5 and adjust as necessary,

7.

then tighten hex nuts on bearing block studs.

. Using straightedge and feeler gauge set,

4

inspect cutterhead parallelism with outfeed
table as shown in Figure 6. With straightedge
in position, raise or lower outfeed table until
cutterhead body (not the carbide insert) just
touches straightedge.

8. Place a straightedge on outfeed table
so it extends over cutterhead, and rotate
cutterhead pulley until one of the carbide
inserts is at top-dead-center (TDC), as shown
in Figure 7.

9.

Lock outfeed table, then re-install fence.

Re-install V-belt on pulleys (refer to instruc-

10.

tions in your G0813/G0814/G0814X manual
for details).

IMPORTANT: When correctly set, carbide

insert will just touch straightedge when insert
is at its highest point of rotation.

Straightedge

Outfeed Infeed

Figure 7. Cutterhead insert at top-dead-center.

— If your outfeed table is correctly set, no

adjustments are necessary.

— If insert lifts straightedge off table or if

table is below straightedge, adjust outfeed
table height with handwheel until straight­edge just touches an insert at its highest
point of rotation.

Re-install rear panel and belt guard.

11.

Install cutterhead guard back over cutterhead,

12.

making sure that spring tension in guard
is properly set so guard springs back over
cutterhead when it is pulled back and
released.

T31849 6" V-Helical Cutterhead

Replacing/Rotating Indexable Inserts

The Model T31849 V-Helical Cutterhead is
equipped with 4-sided indexable carbide inserts.
Each insert can be removed, rotated, and re­installed to use either of its four cutting edges.
If one cutting edge becomes dull or damaged,
simply rotate it 90º (see Figure 8) to use a sharp
cutting edge.

To replace or rotate an indexable insert:

1. DISCONNECT MACHINE FROM POWER!

Set fence to 90° and move it all the way back.

2.

Remove cutterhead guard and lower infeed

3.

table as far down as it will go.

Remove belt guard to access V-helical

4.

cutterhead pulley.

Reference Number

Figure 8. Rotating indexable carbide inserts.

The inserts have a reference number on each
corner. The position of the reference number on
installed inserts can be used to track which edges
are sharp/unused and which edges are dull or
damaged. Replace inserts once reference num­ber has been rotated back to its original position.

and hands.

8. Remove Torx screw and indexable insert.

Clean all dust and dirt off insert and cutterhead

9.

pocket from which insert was removed, and
replace insert so a fresh, sharp edge is facing
outward.

Note: Proper cleaning is critical to achiev-

ing a smooth finish. Dirt or dust trapped
between insert and cutterhead will slightly
raise insert, and make noticeable marks on
your workpieces the next time you cut.

Lubricate Torx screw threads with a light

10.

machine oil, wipe excess oil off threads, and
torque Torx screw to 48-50 inch pounds.

Note: Excess oil may squeeze between insert

and cutterhead or in screw hole, thereby lifting
insert or screw slightly and affecting work­piece finishes.

11. Re-install belt guard and raise infeed table.
