My timing chain on my FE 501 did just break....
And now I'm wondering where I can get a new one and if its smart to use the old one? It was only a link that did break if I get a new link it will be as good as new? And how should i fit the new one?
 
would be a good idea to get a new one, I use the parts suppliers in my signature

I would also be checking piston and valves for damage after the chain has broken, checking the cam follower bearings and valve springs would also be a good idea

edit; re how to.... the workshop manuals are located here http://husaberg.org/service-manuals/

Don`t

Head off! i did the mistake to just change the cam chain when it was broken on my 501.
One valve broke few hours later.
Had to repair the engine for 16500:- SKR!

Every good friend from Slovakia and near area would give you following advice: buy an used chain link (new one would rattle), put the old chain on and get rid of the bike, dont forget to say the new owner that the engine is after complete rebuild worth at least 1000€, that everything is new inside the engine and that you are stealing your own family selling the bike so cheap. I love my country, it is so beautiful, but the people are ... still dont know the right word. And yes, put the head down, the halves apart, you must see what else is wrong, be prepared to get upset. It is allways better to know what is the reality. And another good advice: listen to people who know what they are talking about. You are most probably new here and to fourstrokes in general (asking such question), so first one of them for you to know is bushmechanic.
 
Hi skjetvingen,
Please check your engine thoroughly!!!
It may look that the engine has a good compression, but it's very good possible that the valves are bend and rammed into the cylinderhead that hard and so it seemes that the compression is O.K IT'S NOT!!!!
Be wise and follow the advise given here above !!!

p.s.Be aware!! The wizard from down under could cast a spell on you:D
 
Taffy has timing chains too and allegedly ships to Norway ( hehe). Anyway, don't be penny-wise and pound foolish. Check the motor thoroughly and replace the chain. It's relatively cheap compared to the damage a chain break can do. Indeed, listen to Bushie!

you could leave the head on and leave the ports full of white spirit.

but as Edelwiess might put it - I'm not worth listening too.
 
taffy, what is wrong with you? dont take it personally, u are allways like that. I just suppose that if someone failed to change cam chain in time, there can be more mess down under, checking valves may not be enough. thats it, no more, no less.

Hi

its your bike dude! you can do whatever you want

you don't need to take the head off but it could be expensive later if you don't... but if you have to pay someone to take the head off it will be expensive anyway

you can buy a single link for about $3.00 .. if you want

can we see a picture of the broken chain? im curious which part of the chain failed.

good luck

cheers Bushie
 
Took the side cower of and did find a half tappet lock nut... I think this is going to be expensive anyway so the next thing I will do is to take the head of ;)
 
Hi Skjetvingen,
It's a wise decision to disassemble the engine and to take a good look what's
gone wrong!!
I once had,as a mechanic,a V 8 engine with a gear wheel driven camshaft wich broke on idling,as told before that this happened with a lot of force that the valves were bend in their guides.
The valvesprings were good,the valves seemed to seated good,even with the white spirit test in the combustionchamber ,but when i looked into the in and exhaust channels i saw the bend valves!!!:(
Hoping that repairs will be not to expensive.

p.s.And Sket you can look at the bright sight to it,you get to know your bike even better;)

@Goose love the expression about pennywise,poundfoolish :)

now how do I find out if they are bent?
 
Hi Skjetvingen,
I don't know if you can look into the intake and exhaust canal maybe you can see it,if not you have to disassemble the valvesprings to take them out.
Hoping for the best.

best way is in a lathe

but you could take the valve springs off and rotate the valves by hand in the guides you will see a wobble of the head if they are bent a lot

then put a bit of Prussian blue or texta color marker or even lapping paste on the valve seat and rotate the valve pushing it into the seat, you will see the contact area, if bent there will be asymmetrical contact on the valve
 
Thanks, but what's the best way to make a tool to take of the valve springs? I remember you did make one bush?
 
Hi Skjetvingen,
I don't know how my wizard maestro did it, i modified a glueplier, wich are used to glue pieces of wood to gether, it worked perfectly on the Husky cylinder head jobs.
If you look at google you can find pictures of what i mean, in Dutch it's called "lijmtang".
It should be possible to get one at a hardwarestore.
I hope that this works out for you.

Grtz Rens

p.s.It's possible that if the valves are bend, you need some brute force to get them out of valve guides.
