Ok I have tried numerous times now to get responses on here on a real technical question. I went and bought the Honda Clymer manual for my fourwheeler like u suggested and looked at everything I can figure out, and I still cant figure out how to see if my cam has slipped time without opening the case. I need to know how to see if my cam has slipped time without opening the care, please please please help me, this is urgent.

 

The rear engine cover must be removed to view the timing marks. If you remove the recoil starter, stator cover and flywheel, the marks should be visible. The cam alignment cannot be changed without removing the rear engine cover, as the camshaft must be pulled back from the block to allow for cam chain slack available to permit it to be adjusted to the proper tooth alignment setting. Also the cam chain tentioner is under this cover and must be removed to let the cam chain be removed. The cam in this engineblock and is not in the head, rather below the cylinder in the crankcase which makes cam chain timing difficult to check. Everything involved is under the rear engine cover which requires the rear suspention swing arm to be removed which will allow the rear cover to be slipped off the rear output shaft which in turn is splined onto the driveshaft which runs through the swing arm. This is why the rear swing arm, and rear engine cover must be removed to check cam timing

Plain and simple facts

Keep in mind this motor has been bored three times to approximate .30 over. There appears to be no problems with piston, jug, valves, etc only carbon build up ontop of piston and on valves but not enough to hurt anything.We think if its not the cam chain and tensioner it could need a stock jug and cylinder and piston to create a more genuine stroke. We are thinking of possibilitys and because the four wheeler would pull the wheels off the ground the day it stopped running we doubt its the piston rings or jug, it had good compression/has. We are trying to figure out whether its in time without pulling the whole motor, and without pulling the rear case and removing all differentials etc, we need help.

 

Im sorry for the constant post but this is nerve racking and driving me crazy is it common for a rancher or honda fourwheeler to slip time, is it possible for the cam to slip time and need new chain and tensioner? what causes it?

 

I answered this yesterday (on your last post) ..


I wouldn't pull the cam out to re-time it with the cam followers (cam buckets) still in the crankcase , if 1 drops inside the crankcase you will have to split the transmission to get it out ..

 

Ok so most suggestions on here didn't help except from Gimpster about how to get to it. Anyways I worked my *** off today on the Rancher. I started at 1230pm Its one hell of a job for something that seems so damn simple. I had to remove brake lines, and all lines in way of swingarm removal I had to take off side clips and use 17mm hex to remove left side axle and right side didnt have special tool and heated it up and it had no function and bearing were shot so get swingarm off and took off mud guards, starter, recoil starter, removed 3 million bolts and finally removed rear case at about 530 pm and the flywheel has a special tool we dont have so not sure what we are going to do if honda wont let us borrow it. The chain is extremely loose, and the cam is far out of time, so we will get it in time, put on new cam chain and tensioner use adjuster to adjust it put back together put top end back together with new gaskets, and im going to put new swing arm bearings then start it once put all together without plastics take it to our car wash and wash all the old dirt, and corrosion off of it, and make it like new then im going to wax the plastics spray paint the racks like new, and put plastics back on, I cant wait to have it all done 900 dollars spent 100-200 dollars in parts, eventually brakes, and hopefully I have a awesome fourwheeler does anyone klnow of a way to get flywheel off without specialty tool or hurting nething suggestions would be greatly appreciated/\

 

Ironic, I have one that came across my bench this morning with the same problem. I came on here to let you know what I will find with it this afternoon after tearing it down. I see you found it was cam chain out of time on yours though.

If the flywheel was installed with an impact, you will have to borrow a puller. A lot of times when the flywheel is installed by hand and torqued to spec, they will nearly fall off when the center bolt is removed. Kind of tells me something about the tech who rebuilt that engine last.
