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.

4.
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.

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.

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.

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.
