the grease path is correct and mark the

rubber bearing along the top casting.

Pay close attention of how you

disassemble gang. Remove 5/16 x 4 hex bolts

(2) and 5/16 lock nuts and slide thread

protector (3) off 1 3/4 slotted nut (4). Remove

1 3/4 slotted nut (4) with gang wrenches.

Slide all components off gang bolt and lay in

order you took them off. If it is a used

machine discard all the bearings (5) and short

half spools (6). If new machine you will re-

use bearings.

You are now ready to re-assemble

gang. Clean bearing casting top (7) and

bottom (8). Hand tighten the 1 3/4 slotted nut

on one end of the gang bolt about the same as

it was before disassembling or to where the

5/16 x 4 hex bolt will go through slot in nut

and hole in gang bolt easily. Install a gang

wrench over castle nut (4) and install 5/16 x 4

hex bolt (2) only to hold first castle nut

position during re-assembly. Re-assemble

components as shown on page3. Install new

bearings, if applicable. Use new half spool

short (8) on all applications. Be sure to install

new Bearing Shield (10), one on each side of

bearing. Make sure grease path alignment is

correct during re-assembly, and grease zerk

(15) is to the rear of the machine, see page 3.

On Model 4336DH you will need to

install another bearing (5) on the right front

and left front gang in position shown in

placement drawings on pages 4-5. This will

go between the 3

and 4

blade from outer

end of each gang. You will also need to add a

bearing shield on each side of this new

bearing and a new half spool long (9) & short

(6). This is a list of the part numbers in 4336

update kit that are used on gangs.

After getting all components

assembled you can torque the 1 3/4 slotted nut

on other end to the torque specs on page 6.

Before installing thread protector caps (3), fill

both castle nut slots with grease and fill the

thread protector caps 1/3 full of clean grease.

Reinstall the two thread protector caps (3) and

5/16 x 4 hex bolt (2) and 5/16 lock nut.

On Model 4336DH you will need to

install a new c-shank assembly on the right

front and left front gang in position shown in

placement drawings on pages 4-5. Bolt the c-

shank RH or LH, (11), c-shank plate top (12)

and c-shank plate bottom (13) using 3/4 x 5 x

6 1/2 u-bolts (14), 3/4 lock washers, and 3/4

hex nuts as shown on page 3. Don’t tighten u-

bolts until you get gangs back in position.

When you have gangs

reassembled you may start bolting them back

to machine. You can lower the wings down,

then slowly lower the machine down and bolt

gangs on just like you took them off. Slide

scraper bar assemblies back in position and

tighten 1/2 x 2 x 3 1/4 u-bolts. Now you can

tighten all bolts.
