Timing Adjustment Procedure

The timing adjustment procedure for the Honda 3.5 engine involves setting both intake and exhaust valves at specific settings in order to ensure proper functioning of the engine while running at its optimal performance level. The first step in this process is setting the intake valve timing by rotating the crankshaft pulley clockwise until it reaches its full lift point (or stop) when measured with a feeler gauge inserted between the intake rocker arm and its associated cam lobe face plate at the front of cylinder head cover plate (or front cover). Once this point has been reached, adjust each individual rocker arm’s screw until it just contacts its associated cam lobe face plate while still allowing slight movement when measured with a feeler gauge inserted between them as well; repeat this process for all intake rocker arms until they are all properly adjusted according to spec outlined in your owners manual for specific instructions on how far each rocker arm should be set from its associated lobe face plate (or stop).

Intake Valve Timing Adjustment

Once all intake rocker arms have been adjusted according to spec outlined in your owners manual, rotate crankshaft pulley counterclockwise until it reaches its full lift point (or stop) when measured with a feeler gauge inserted between each exhaust rocker arm and its associated cam lobe face plate at rear cylinder head cover plate (or rear cover). Once this point has been reached, adjust each individual rocker arm’s screw until it just contacts its associated cam lobe face plate while still allowing slight movement when measured with a feeler gauge inserted between them; repeat this process for all exhaust rockers arms until they are all properly adjusted according to spec outlined in your owners manual for specific instructions on how far each rocker arm should be set from its associated lobe face plate (or stop).

Exhaust Valve Timing Adjustment

Once all exhaust rockers arms have been adjusted according to spec outlined in your owners manual, rotate crankshaft pulley counterclockwise one more time until it reaches its full lift point (or stop) when measured with a feeler gauge inserted between both intakes and exhauts valves simultaneously at their respective points of contact; once these points have been reached adjust each individual valve’s screw accordingly until they just barely touch their respective faces plates while still allowing slight movement when measured with a feeler gauge inserted between them; repeat this process for both intakes and exhauts valves until they are all properly adjusted according to spec outlined in your owners manual for specific instructions on how far each valve should be set from its respective face plate (or stop).

Camshaft Intake Measurements

In order take proper measurements from camshaft intakes during Honda 3.5 valve adjustment procedures it is necessary to measure two parameters: lobe lift values and cam base circle radius values; these two parameters can then be used together along with other measurements taken during timing procedures such as Theta angles or degrees of rotation (for example: 20 BTDC or 10 ATDC) in order determine if any adjustments need made such as increasing/decreasing clearance between lobes/valve faces plates etcTo measure lobe lift values place an appropriate sized feeler gauge between an intake rockers arm screw head/washer and its associated faceplate located at front cylinder head cover plate (or front cover); record reading obtained then repeat same procedure for remaining intake valves/rockers arms located at rear cylinder head cover plate (or rear cover); average these readings together then record final value obtained which will represent overall lobe lift value measurement taken during inspection phase of procedure; To measure cam base circle radius values place an appropriate sized dial caliper across widest diameter portion found along perimeter edge of intake camshaft; record reading obtained then repeat same procedure if multiple intakes exist within engine design; average these readings together then record final value obtained which will represent overall cam base circle radius value measurement taken during inspection phase of procedure; use results obtained from both lobe lift value & cam base circle radius value inspections together along with other readings taken during timing procedures such as Theta angles or degrees of rotation (for example: 20 BTDC or 10 ATDC) in order determine if any adjustments need made such as increasing/decreasing clearance between lobes/valve faces plates etc

Camshaft Exhaust Measurements

In order take proper measurements from camshaft exhausts during Honda 3.5 valve adjustment procedures it is necessary to measure two parameters: lobe lift values and cam base circle radius values; these two parameters can then be used together along with other measurements taken during timing procedures such as Theta angles or degrees of rotation (for example: 20 BTDC or 10 ATDC) in order determine if any adjustments need made such as increasing/decreasing clearance between lobes/valve faces plates etcTo measure lobe lift values place an appropriate sized feeler gauge between an exhaust rockers arm screw head/washer and its associated faceplate located at rear cylinder head cover plate (or rear cover); record reading obtained then repeat same procedure for remaining exhaust valves/rockers arms located at front cylinder head cover plate (or front cover); average these readings together then record final value obtained which will represent overall lobe lift value measurement taken during inspection phase of procedure; To measure cam base circle radius values place an appropriate sized dial caliper across widest diameter portion found along perimeter edge of exhaust camshaft; record reading obtained then repeat same procedure if multiple exhausts exist within engine design; average these readings together then record final value obtained which will represent overall cam base circle radius value measurement taken during inspection phase of procedure; use results obtained from both lobe lift value & cam base circle radius value

Tensioner Adjustment Procedure

In order to ensure proper engine performance, the tensioner must be adjusted properly. The procedure for adjusting the tensioner on a Honda 3.5 engine is as follows: Start by removing the spark plug from the cylinder head and disconnecting the ignition coil wire. Next, locate the tensioner adjustment bolt and loosen it until it can be turned with a wrench. Turn the bolt clockwise until it is snug, but not too tight. This will ensure that there is enough tension on the timing belt to allow it to turn freely without slipping. Finally, reconnect the ignition coil wire and replace the spark plug before starting up your engine.
