How-To Install A TF067300AJ Valve Plate Kit

The valve plate design for your compressor has changed.

The new design offers the same performance (cfm) as the  
old, but uses o-ring seals instead of gaskets.  O-rings 
ensure a more reliable seal with less dependence on head torque.

Additionally, the o-rings allow greater heat transfer through
the pump, resulting in lower operating temperatures.  

To take advantage of these improvements, a new head 
--included with the kit you received -- must be installed.

To change the valve plate, follow the steps below:

1) To remove air filter assembly:

(a) Unscrew wing nut on air filter and remove washer

(b) Remove top filter housing and air filter element

(c) Unscrew 3 bolts holding bottom filter housing to head

(d) Remove bottom filter housing and o-ring seal

Save all parts -- they will be used on new head.

2)  Remove 9 head bolts.  Pry off head and valve plate
with a screwdriver.  Scrape the gasket off of the cylinder.

3) New valve plate installation:

(a) Install the valve-plate-to-cylinder o-ring by pressing it
into the bottom groove in the valve plate.

(b) Install the head-to-valve-plate o-ring into the top
groove in the valve plate.

(c) Fasten the head to the valve plate with the head-to-
valve plate screw (self-tapping).

(d) Torque screw to 100 in-lbs.

4)  Make sure cylinder surface is clean.

5)  Install head and valve plate assembly on cylinder. 
Reinstall 9 head bolts and tighten in a criss-cross pattern.
Torque bolts to 500 in-lbs.
