VALVE STEMS

All Gasoline Models

Intake and exhaust valve springs

are interchangeable. Springs should be

installed with damper end (closely

wound  coils)  towards  cylinder  head.
Renew  any  spring  that  is  rusted,
discolored,  distorted  or  does  not  test

VALVE ROTATORS

All Gasoline Models

31.

Normal servicing of the positive

type exhaust valve rotators ("Rotocaps")
cons1sts of renewing the units. It is im

portant, however, to observe the valve ac

tion after valve is assembled. The valve

rotator can be considered satisfactory if
the valve turns a slight amount each

time the valve opens.

Fig. 34-When renewing velve guides, distance

(A)

from top of guide to rocker cover gasket surlace

should be 2.38 mm (3132 Inch).

CAM FOLLOWERS

All Gasoline Models

32.

The mushroom type cam followers

(tappets)  operate  directly  in  machined
bores  of  the  cylinder  block  and  are
available  only  in  standard  size  of

14.262-14.275

(0.5615-0.5620

inch).

Clearance in bore should

0.013-0.046

(0.0005-0.0018

inch).

The

cam

followers can

removed from

below after removing camshaft as out

lined in paragraph

Cam followers

should

reinstalled in their original

positions ifbeing reused. Cam followers

should be renewed if camshaft is
renewed.

REMOVE AND REINSTALL.

First separate t.he fr-ont system from the
engine as follows: Drrun cooling system,

remove front grille panels and discon·

nect battery cables. Remove fuel tank

cap, radiator cap and hood. Disconnect

headlight wires and pull wiring free.
Disconnect both radiator hoses, radiator

brace and, on models

equipped,

hydraulic  oil  lines  and  front  mounted
pump.  Support  tractor  at  front  of
transmission.  Position wedge blocks be·

tween front axle and axle support. Sup

port the front end assembly at front and
rear. Disconnect drag links and radius

rods at rear of models so equipped. On

models with drag links, attach drag
links to axle so wheels will be straight

ahead and will not turn. On models with

power steering,  disconnect lines, remove
the  power  steering  pump  and cover  all
hydraulic  steering  openings.  On  all
models,  unbolt  the front  assembly  and
carefully  roll away from  tractor.

Remove the fan belt and crankshaft

pulley. Detach the spring and rod from
