Royal Enfield Timing Cover comes off

[kanakaken]

After stripping down the engine I found the thrust washer left in the timing case was not the cause of the big end going. The oil pump still worked, not perfectly, for some teeth were worn off. The cause was either poor material in the big end, or the OPR valve. Enfield have played around with the OPRV for years because it has given trouble before, so I'm guessing that's where the trouble lies. Only time will tell, the dealers & their mechanics don't know & Enfield HQ, will say nothing.

A crank nut going loose....thats not good...i see ur bullet has standard timing gear pins...i have recently got myself a adjustable...it works great....i shall upload the video soon...

Sometimes when my 2005 Bullet gets hot from sitting in traffic, I hear a loud knock on every stroke too. It is very loud and metallic. When I accelerate and get moving, sometimes it stops knocking suddenly and I feel a little boost in power at the same time. I am not sure if this happens when the engine cools down from air movement or what. I am trying to pinpoint it and thought maybe it was the head gasket since there seems to be fresh oil around there.

@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....................

When I removed my timing case cover I found a thick thrust washer had been left inside the case during factory assembly, causing the oil pump to fail which cause the big end to blow. Resulting in a major engine rebuild. Bits of bush metal every where. One item of a long list of factory faults on my 2006 Bullet. BUYER BEWARE,,, Indian quality control,,,,,, what's that ??

[faisalfurruq]

@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....

@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.

[faisalfurruq]

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



[faisalfurruq]

@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]

@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.

@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]

@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........

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.

[faisalfurruq]

@tk409 Dear Friend... My name is Faisal Furruq I am from India.... after seeing the video uploaded by you, I am a user of a bullet too.... I've noticed that the cam wheels have a play. there few reasons of over heating of a Bullet, first remove the spark plug then take the piston position right to the top the your cam wheels will come to the matching point of six dots, then remove the small pinion by removing warm nut, and replace it with the 1 or 2 size pinion.

[faisalfurruq]

@tk409 I do see that your bike's timing is not proper due to that your engine may be over heating... before opening the engine do follow some steps..

the Gobbling sound may be of a lose clutch chain just adjust it and see.... it may help you in killing the sound....

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

One thing, i would have removed the oil "jet" first, it makes it a lot easier and the risk of it breaking is smaller.

[joralebedev]

Did you find out what was wrong?
