INSTALLATION PROCEDURE Note: All Evolution® “Big Twin” pistons are marked “Front” or “Rear” and come with rings, wrist pins, and locks. • Note: We highly recommend that a dealer or trained mechanic perform the installation of these pistons. Specialized equipment is required for honing and finishing the cylinders to ensure long life of the piston and cylinder assembly. 1. Remove original equipment cylinders from engine. Refer to a shop manual or other reference book for specific steps, if needed. (Note: Care should be taken not to bend the studs or damage the cylinder during removal of the cylinders.) 2. With a small screwdriver, move the wrist pin retainer around to gain access to the tail of the retainer as it lines up with the notch in the bottom of the wrist pin hole. 3. Use a small screwdriver, pick or awl to roll the wrist pin retainer out of its groove. 4. Push wrist pin out and remove piston. 5. Repeat procedure for the other piston. 6. At this point, take cylinders, new pistons, and piston-to-wall clearance specifications to your dealer or machine shop to perform necessary machining operations. • IMPORTANT NOTE (Evolution® and Twin Cam®): The cylinder bore must be machined/honed to provide .0025″ of piston-to-wall clearance. Measure the piston diameter at a point .500″ up from the lower skirt (See Figure 3). 7. Starting with the front cylinder, install new piston rings and one wrist pin retaining clip (Note: Second ring has a dot which must face up when the ring is installed) . 8. Place the piston over the conecting rod, making sure that the intake valve pocket is towards the intake side. (For Evolution ® , see Figure 1. For Twin Cam ® , see Figure 2) . Coat the wrist pin with engine oil and insert it into the piston. Install the second wrist pin retainer into the groove. 9. Lightly coat the piston skirt with engine oil. Place a piston ring compressor over the piston/ring assembly and compress. Place the cylinder over the piston and gently push down until all rings are in the cylinder. Remove the ring compressor, and push the cylinder the rest of the way down. (Note: Be careful not to get oil onto the base gasket.) 10. Place two nuts and washers on opposite corners of the #1 cylinder to hold it down while you repeat the procedure for cylinder #2. 11. Assemble the rest of the engine per factory specifications. Start the engine and let it run at 2000 rpm for about 10 minutes.

The cylinder sleeves provided with the Wiseco V-Rod big bore kit have been finished honed to size and the piston to cylinder clearance has been set. Prior to installation, the sleeves must be washed in hot soapy water (not parts washer solvent) and dried. Coat the bore surface with motor oil and wipe it with a white towel. If the towel shows any remaining grit, repeat the hot soapy water washing process until the towel will only show clean motor oil. CAUTION: Test fit the cleaned sleeve (without O-Rings installed) into the engine block. Sleeve should drop into position. If sleeve will not easily drop into position, warm the engine block with a hair dryer until sleeve will drop into position. Remove sleeve, then continue installation procedures. From the bottom side of the sleeve, gently roll the 2-cylinder sleeve O-rings into the two grooves on each sleeve. Apply motor oil to the O-rings and gently install the sleeves into the block until bottomed. CAUTION: DO NOT ATTEMPT TO INSTALL SLEEVES WITHOUT LUBRICATING THE O-RINGS. FAILURE TO LUBRICATE O-RINGS COULD RESULT IN TORN OR DAMAGED O-RINGS THAT WOULD NOT BE EVIDENT UNTIL ENGINE WAS STARTED. INCORRECTLY INSTALLED O-RINGS CAN RESULT IN CATASTROPHIC ENGINE DAMAGE. NOTE: REFER TO THE OEM SERVICE MANUAL FOR ALL TORQUE SPECIFICATIONS PISTON RING PREPARATION Wiseco V-Rod pistons incorporate an advanced 2 ring system • The top ring is file-fit, and as such, requires that the end gap must be clearanced. The proper end gap clearance is .016-.018″ with the ring installed squarely in the bore. The top ring must be installed on the piston with the dot marking toward the top of the piston. • The oil ring is comprised of the expander and two rails. Install the expander first, and then the rails. Check to make sure the expander tips have not overlapped. It is not necessary to clearance the end gaps on the oil rails. The rails should be installed without modification. PISTON INSTALLATION The Wiseco V-Rod big bore kit is supplied with pistons that are front and rear cylinder specific. Install the front piston 4792M10795 in the front cylinder with the arrow facing the front of the engine. Install the rear piston 4793M10795 in the rear cylinder with the arrow facing the front of the engine. A piston ring compressor is required to install the pistons into the cylinders.

check Piston Alignment in Cylinder Bore The purpose of this procedure is to check for and correct possible piston misalignment in the cylinder bore. During normal manufacturing, engine components such as crankcases, cylinders, and connecting rods can be machined to dimensions within factory specifications but on the extreme ends of the tolerance range. Sometimes these components when combined together form an assembly that is borderline or actually “out of print”. The worst result is that the pistons can run cocked in the cylinder bores causing the connecting rods to thrust to the sides exerting unnecessary stress on the pistons, rings, rod bearings and other related parts. This procedure is not the same as “blue printing”, but it provides almost the same result. We feel that not enough emphasis is given to checking the piston alignment in the cylinder bore. NOTE – All engines should be checked upon disassembly. This applies to any engine receiving new pistons which includes those being completely overhauled. CAUTION – Pistons which do not run true in cylinder bores may cause excessive connecting rod side thrusting. This may lead to premature ring, piston, connecting rod and rod bearing wear and eventual failure of these parts. Visual Procedure A. Reinstall cylinders on old pistons without rings. Hold cylinders securely in place. B. Move piston tight toward camside of engine. C. Turn engine over in normal direction of travel 2 or 3 revolutions and observe piston during process. D. Move piston toward driveside of engine and repeat Step C. If misalignment exists, piston will appear closer to cylinder wall at one point around circumference. Condition can be corrected by bending rod in opposite direction. Figure 1 shows an exaggerated side view. E. Repeat Steps B to D for other cylinder. F. Remove pistons and cylinders. Observe pistons for wear spots on sides above top compression ring. If either side near wristpin is worn clean while side opposite is carboned up, then piston was not running straight and true in cylinder bore. Piston will also generally show diagonal wear pattern on thrust faces of skirts and possibly signs of connecting rod to wristpin boss contact inside piston.
