In a piston valve, the control of stem and seat leakage is obtained by tightness of the valve sealing rings to the body and valve plug. The bonnet compresses the valve sealing rings against the body and the valve plug. Flexible disc springs automatically assure a tight seal by exerting pressure on the valve sealing rings, keeping them compressed. Opening and Closing the TVS Isolation Valves The isolation valve begins to stop flow when the valve plug enters the lower valve sealing ring. When the isolation valve is completely closed, the valve plug is in contact with the full height of the valve sealing rings, ensuring the best possible seal. In fact, there is no advantage to be gained in torqueing the valve closed. Armstrong recommends that after closing the isolation valves completely, the handwheel should be turned back one half turn. This makes it easy to re-open the valve by avoiding metal to metal seizure. Troubleshooting – Isolation Valves A piston valve will retain its leak tightness for several years without maintenance. In severe service, such as rapid heating and cooling, some field maintenance may be required. Depending on the problem, these simple steps may help: ! ! ! ! ! Isolation Valve leaks, when the valve is closed . First, Check to make sure the valve is actually closed . Check to see if bonnet is seated on the body, if not, tighten the bonnet nuts until the bonnet seats. This recompresses the valve sealing rings against the body and the valve plug. If valve continues to leak, replace the isolation valve assembly

Each cylinder should be deburred on top and generously chamfered on bottom for ease of piston and ring installation. Finish hone with a 280-400 grit hone. A good cross hatch finishing pattern is important for best results. CAUTION: Wash cylinder assembly with soap and water, then swab with new # 10 oil on a clean rag until all tendency of rag discolor is gone. Washing in solvent will not remove the abrasive from finished cylinder walls

High-pressure fluid flow The engine rotates the pump swash plate, which has a gear mechanism. The rotating swash plate pushes the pump pistons to increase the pressure on the hydraulic fluid and feed it to the high-pressure annular chamber. The high- pressure fluid is then fed to the oil motor piston chamber where it pushes the pistons forward, which then push the motor swash plate. Power Fluid flow from pump to motor Fluid flow from motor to pump Low-pressure fluid flow The lower-pressure hydraulic fluid returns to the pump through the low-pressure annular chamber. In this way, the fluid circulates between the pump and the motor. Movement of distributor valves and pistons The distributor valves play an important role in fluid circulation. The valves are placed both in the oil pump and motor. When the pump pistons move to the compression side, the valves connect the piston chamber and the high- pressure chamber. When the pump pistons move to the expansion side, the valves allow a connection between the piston chamber and the low-pressure chamber. The valve in the oil motor moves opposite to its counterpart in the pump, ensuring the circulation of fluid within the system

Upon installation of your WEB-CAM camshaft, check the following. These operations are very important to engine
life, please follow instructions! If your cam is described as a bolt-in in the WEB-CAM catalog, you may skip 1-5
below. Check piston to valve clearance. Provide the necessary clearance by removing material from the piston Minimum .050″ intake, .080″ exhaust.1. Check valve to valve clearance. It may be necessary to remove material from the valves or sink valve seat height in head. 2. Check the valve spring retainer to valve guide clearance at maximum lift. Remove material from the top,of valve guides to provide a minimum of .030″ clearance. 3. Check for valve spring coil bind at maximum valve lift. Clearance at every coil should be at least .015″4. Be certain that cam and/or rocker arms rotate
freely in head or block. Remove material from head,block, or rocker arms where necessary.5. Engine and cam life depend on proper installation. New or reground followers should be used when installing WEB-CAM profiles. Apply the provided
assembly lube to cam lobe and follower surfaces

Boring and Honing Procedures 1. Check again for burrs on cylinder gasket surfaces and remove burrs before performing Step 2. 2. Install original head and base gaskets, CYLINDER TORQUE PLATES (Part Number 33446-A) and TORQUE BOLTS (Part Number 33446-4). Tighten TORQUE BOLTS following tightening procedure given in the INSTALLATION, CYLINDER HEAD procedure in the ENGINE section of the Service Manual. NOTE Torque plates, properly tightened and installed with gaskets, simulate engine operating conditions. Measurements will vary as much as 0.001 inch without torque plate. 3. The cylinder must be bored with gaskets and torque plates attached. Bore the cylinder to 0.003 inch under the desired finish size. 1 WARNING CAUTION CAUTION 1 WARNING Kit Number 4. Hone the cylinder to its finished size (See Figure 1) using a 280 grit rigid hone followed by a 240 grit flexible ball hone. Honing must be done with torque plates attached. All honing must be done from the bottom (crankcase) end of the cylinder. Work for a 60 degree crosshatch pattern. 5. See Figure 1. After machining and honing, chamfer the bottom edge of the cylinder liner. the chamfer provides a beveled surface for easier installation of the cylinder over the piston rings. Break leading edge of liner to a flat surface. The bottom edge of the liner will be somewhat sharp after machining. This sharp edge could easily be damaged during installation of the cylinder. Piston Installation The 1200cc pistons have an arrow on the top of the piston. This arrow must face the front of the engine when piston is installed. There is no front cylinder piston or rear cylinder piston. New pistons can be installed in either cylinder. Check piston rings for proper side clearance and end gap (See XLH Service Manual). Be sure end gaps of adjacent rings are installed 90 degrees apart. Assembly Follow assembly and torque specifications given in the ENGINE section of the applicable Service Manual. Replace original gaskets, O-rings and seals with new components furnished in kit. NOTE Push rod covers on 1991 and later models are one-piece and the correct O-rings are as follows: Bottom – Part Number 17944-89 Upper – Part Number 11190 Engine Break In For the first 500 miles, to wear-in critical parts, observe these few simple driving rules: During the first 50 miles, keep the engine speed below 2500 RPM in any gear. Up to 500 miles, vary the engine speed, avoiding any steady speed for long distances. Engine speed up to 3000 RPM is permissible in any gear. Avoid fast starts at wide open throttle. Drive slowly until engine warms up. Avoid running the engine at extremely low RPM in higher gears. 2 of 3 -J00001 1200cc CYLINDER FINAL BORE SIZE AFTER HONING STANDARD BORE DIAMETER 3.4980 inch + 0.0002 inch Figure 1.

BRAKE LEVER INSTALLATION Do not remove or install the master cylinder assembly without first positioning a 5/32-inch (4 mm) thick insert between the brake lever and lever bracket. Removing or installing the master cylinder assembly without the insert in place may result in damage to the rubber boot and plunger on the front stoplight switch. (00324a) is 01010 Figure 1. 5/32 in. (4 mm) Cardboard Insert 1. See Figure 1. Squeeze the brake lever and place the cardboard insert between the brake lever and lever bracket. NOTE Use the eyelet of an ordinary cable strap if the cardboard insert is not available. NOTE Do not remove the handlebar clamp or switch housing assembly to remove the brake lever. Wear safety glasses or goggles when removing or installing retaining rings. Retaining rings can slip from the pliers and could be propelled with enough force to cause serious eye injury. (00312a) 2. See the Figure 2 and the FRONT BRAKE MASTER CYLINDER section of the Service Manual. Remove the retaining ring (4) from the groove in the pivot pin (B) and discard retaining ring. 3. Remove the pivot pin and retain for re-use. Remove and discard the original equipment brake lever and pivot lever bushing. NOTE New brake levers come with the pivot lever bushing installed. NOTE Follow the instructions in Steps 3 and 4 carefully in order to prevent the actuating tab on the brake lever from damaging the rubber boot and plunger of the front stoplight switch. -J04342 1 of 3 4. Gently press and hold the piston cap (A) forward with a screwdriver. Slip the brake lever into position and align the pivot pin holes. 5. Install the pivot pin removed in Step 2 and new retaining ring (4) from kit. 6. Check the front brake for proper operation. There should be no free play in the hand lever. A slight preload is per- missible. A plugged or covered relief port can cause brake drag or lock-up, which could lead to loss of control, resulting in death or serious injury. (00288a) 7. To verify proper operation of the master-cylinder relief port, actuate the brake lever with the reservoir cover and gasket removed. A slight spurt of fluid will break the surface if internal components are working properly. 8. Reinstall the master cylinder cover. Be sure that all lights and switches operate properly before operating motorcycle. Low visibility of rider can result in death or serious injury. (00316a) 9. Check that the stop light goes on when the brake lever is actuated.
