6. remove old rocker arm and replace with new rocker arm, put pin back in to secure the rocker arm
7. look up the valve clearance for your engine.
8. adjust both valves to the correct clearance using the adjustment screw (they will be different)

Timing belt slipped and broke rocker and camshaft

Difficulty
Medium
Time
1-2 hours
Tools Used
Screwdriver, Wrench Set, Nutdriver
I removed the Honda CVS160 engine from the pressure washer base after disconnecting the pump. After removing the rocker/cam cover and discovering the broken exhaust rocker arm and damage to the camshaft I surmised that the timing belt had slipped and caused the damage. I then split the upper and lower portion of the engine case and pulled out the defective timing belt. I had to remove a crankshaft coupling that was keyed to the crankshaft prior to taking the case apart. I installed the new timing belt and reassembled the lower case. I then replaced both rockers and the new camshaft/pulley and replaced the cam cover with new sealer. The engine started and ran perfectly showing that no damage had been done to the valves or piston.

Broken exhaust rocker arm

Difficulty
Medium
Time
30-60 minutes
Tools Used
Screwdriver, Socket set, Wrench Set, Cordless drill
Removed front cover and broke rocker arm, investigated the problem. Exhaust valve was hard to move, PB Blaster the valve ( problem, carbon buildup) worked it gently by hand until it spun freely. Used drill slowly spinning the valve and moving it in and out ( don’t over do it). Cleaned up the area, reinstalled the spring and rocker arm. Reassemble and pulled the starter rope to verify no problem. Be sure to set valves. Pressure washer runs like new

1. Took off broken blades, blade holder and drive belt pulley. This required a two jaw puller due to bend in shaft.
2. Open up crankcase. Many steps involved. Followed youtube videos. Detailed videos exist.
3. Take out piston. Found lots of black soot on piston, crankcase and valve seats. Apparently due to mistiming from running engine with bent crankshaft since this is a pretty new engine always running smooth before accident.
4. Use carburetor cleaner and lots of work to clean piston and case. Put in new valves and use grinding compound to clean valve seats and "break in" valves.
5. Install new crankshaft (also from ereplacement) and all new parts related to timing. The old ones looked fine but did not want to have to open up again in case there was some damage not visible.
6. Assemble everything. Again lots of steps. Take pictures when disassembling, label parts and use youtube videos. A mechanic friend lent me a puller and a torque wrench.
7. New blade holder and blades.
8. Pull starter cord. Starts right off. Runs very smooth. Cuts very well. Success but it is a major project for amateurs. I am retired thus have the time and love this Honda lawnmower. Kind of expensive because of all the new parts but still cheaper than a new Honda and I have only had it a couple of years. Now it's practically new.
