Royal Enfield Timing Cover comes off

When my Royal Enfield engine heats up, I hear (and feel) a loud knocking sound, so I'm taking the timing cover off so I can investigate to find the cause. The rods have been inspected and they need no adjustment, and we've confirmed that the sound is coming from the area seen in the video.

Nothing wrong inside the timing case. I thought the knock was coming from there, but it was deeper inside. Turns out the nut on the crankshaft was loose. This would never happen during normal wear. Someone at the factory went to lunch and came back and forgot to tighten the nut. I ended up taking the whole engine out to get to the crankcase just to tighten the nut.

@tk409 I had that knock on my 441 with a key on rotor that was too loose. Wrong size shaft key all bad!

@faisalfurruq You talk as though you work for Royal Enfield, I find that rather strange as you information & advice seems arse up with care, and I would expect that anyone working for them would have a semblance of knowledge & understanding mixed with basic communication skills. There are 2 idler gears in the timing case. On the inside of each is a thin thrust washer & on the outside of each there is a thick one. An extra outside one was left in the timing case by some wallah during assembly.

@kanakaken (there WAS an extra thrust washer LEFT IN THE TIMING CASE BY THE FACTORY IN INDIA.) you mean to say that instead of 2 washers there were 3 washers...... generally we use thin washers on the cam wheels sometimes 2 or 3 on each cam wheels..................

@kanakaken I did not ASSUME any thing and for your kind information I did not Moved from using any camels or goats......... I've faced these problems and helped myself from over coming these problems..... if you cannot take any suggestions then it's your problem.... I am sharing this information based on my personal experience, I've three bikes with me which are up and running in good conditions & I do not take my bike to any workshop.... I hope your frustration will calm down........

@kanakaken you mean to say that the oil pump gear or the cam wheels............ kindly clear that.....

@faisalfurruq Another thing, why do you ASSUME that I use the wrong oil? I use the same oil as advised by the Enfield factory 20W50. Did you encounter the 'carbon deposits' in your machine or was it in some poor fool's machine who followed YOUR advices? Just because you have advanced from using camels or goat powered carts to a motorcycle, doesn't mean you have gained any mechanical insights, so please refrain from airing unsolicited your vast banks of 'mechanical' knowledge.

@faisalfurruq I hope people who read your "advice" are extremely careful in following it for you are a rank amateur. What I wrote were observations & you'll note they changed with further observations, showing I admit if I am wrong, & I correct myself. THRUST washers are used to take up thrust in the idler gears, & note this, there WAS an extra thrust washer LEFT IN THE TIMING CASE BY THE FACTORY IN INDIA. It didn't stop completely the operation of the oil pump but it DID strip some gear teeth.

@jabgoon this is called oozing. open the Rocker cover & and fasten up all the six head nuts... then kick start the bike & pore fresh oil on the Exhaust valve spring and check the silencer whether your bike is throwing a white smoke, if yes then time for you to replace the Head valves & guides... this is because of bad oil supply....................

@kanakaken :- no my dear friend this washer are used for stopping the clap sound of the cam wheels... before blaming anyone just check your driving skills....

these washers are not responsible for the oil pump failure... it is because of using a high viscosity OIL........ I faced this problem few days back it was due to some carbon deposits blocking the Engine Oil inlet way....
