PART NUMBER: 10.109.420

DESCRIPTION: AUTOTECH Sport 260° Hydraulic Camshaft

Note: If the job seems to be beyond your abilities, we recommend that you refer this installa-

tion to a qualified mechanic. Please read through the instructions before starting your

installation to ensure that you have the tools and understanding of the task.

PROCEDURE:

1. Remove the upper drive belt cover by pulling back the clips at the top of the cover and

lifting the cover up and out. Remove the idle stabilizer valve and hose to facilitate valve

cover/camshaft removal and installation. Remove the two braces running from the valve

cover to the intake manifold. Disconnect the crankcase ventilation hose from the emission

control valve (fig 1, disregard arrows.) Disconnect the electrical connector at the fuel after-

run control valve. Remove the eight nuts holding the valve cover down. Lift off valve cover

while taking care not to damage the rubber valve cover gasket.

2. Move camshaft sprocket to cylinder number one TDC mark by turning the crankshaft

clockwise with a 19mm socket until the dot on the camshaft pulley lines up with the upper

edge of the camshaft drive belt inner cover (fig 3.) Check TDC by removing the distributor

cap and making sure that the rotor is lined up with the notch on the distributor (fig 2.) The

flywheel should also be at TDC (fig 4.) If these marks do not line up, you will need to continue

to rotate the crankshaft until they do.

3. Loosen belt tensioner with a 15mm open end wrench and slide off the camshaft drive belt,

while keeping the belt tension on the lower sprockets so that they don't move or slip. If they

do, you will probably have to re-align them in a time consuming procedure described seperately.

By tyingthe belt via a bungee or other cord to the hood or laying the belt towards the rear

using a weight (wrench etc...) to keep the belt tension, you can install the cam without having

to re-align all of the lower sprockets.

4. Remove bearing caps one and three, in that order. Take note of which end of each cap is

pointing towards you. Caution: The bearing caps are offset, and will break if re-installed

backwards and tightened down. Next, remove the nuts from bearing caps two and five a

little at a time and crosswise so that the spring tension is evenly relieved. Lift cam with

attached sprocket out of the head.

5. Loosen the camshaft sprocket bolt 1/2 to 3/4 turn and tap the sprocket loose using a soft

faced hammer. Remove the bolt completely and remove the sprocket, woodruff key, and cam

seal. Lightly coat the cam seal with oil and place on the new camshaft. Install the woodruff

key and sprocket onto the new camshaft and torque the cam sprocket mounting bolt to 59

ft/lb.
