Unit would not run and backfired through carburetor. Removed valve cover and found broken exhaust rocker arm. Replaced both rocker arms. Performed valve lash adjustment. Reinstalled valve cover and installed new air filter. Unit started up on second pull and took a minute to start running normally.
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 pull
... Read moreed 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.
Removed valve cover. Only 4 bolts
Removed lifter pins ( held in by the cover)
Replaced lifters with new parts and set lash.
Replaced cam pulley
Put sealant on back side on cover. Installed cover by tightening 4 bolts
Let sealant set up over night.
Added oil and gas....... Engine started on first pull!
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
... Read more 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.
1. remove valve cover
2.clean valve cover and matching head area using scraper (put rag down around timing sprocket to keep gasket debris from going into engine.)
3. remove spark plug and put a screw driver or socket extension into spark plug hole
4. rotate the timing sprocket by hand until the screw driver or extension
... Read moreraises up to the highest position = TDC Top Dead Center (mine had a red mark on the timing sprocket which made it easy)
5. remove the pin holding the rocker arm in place (you will need to take the adjustment screw off the old rocker arm and put it on the new rocker arm, leave it loose so you can adjust it later)
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)
9. apply new gasket material for the valve cover
10. install the valve cover, tighten the valve cover bolts (be sure not to over tighten)
11. put spark plug back in and attache spark plug wire
12. start your engine
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 ( donGÇÖt over do it). Cleaned up the area, reinstalled the spring and rocker arm.
... Read moreReassemble and pulled the starter rope to verify no problem. Be sure to set valves. Pressure washer runs like new
