AWO 425 Forum

Hi Michael

OT is correct for Top Dead Centre.. and the answer is YES to all the questions you asked. Apart from compression...

HOWEVER, I opened the cylinder head and found 2 bent push-rods!!!! (Druckstange??)

So that would explain alot! Now I just need to buy some. Can you reccomend where I can get these from? I have looked on oldtimer-teiishop but they are not the same as what I have on the bike.. it as a 1955 AWO

many thanks

Tom

Hi Tom,
it's recommended to find out the reason for your bended push-rods. If you apply the new ones another damage is possible. I would recommend you to remove the cylinder-head and to check AND to renew (or at least to clean) the valve steering and to check (and at least to clean) the rocker arm.

If I read the thread I guess it could be better to overhaul the entire engine (and the rear-wheel-drive?). You could send the parts to germany. In this forum there are some professionals (e.g. mopedprinz, ....). Perhaps they take Pounds too

Please remove the oilpan and check for rough dirt or even fragments. In this case you should overhaul the engine unconditionaly.

Yes push rod= druckstange
valve steering = Ventilführung (http://www.leo.org)
rocker arm = Kipphebel
rear-wheel drive = Hinterachsantrieb
oilpan = Ölwanne

HI Guys,

thank you very much for the advice, it is so helpful!

The good news is that there were no fragments or dirt in the bottom. I checked the valves and they are leaking so I will re-seat them. Poor adjustment could lead to bent pushrods?

The engine has already been overhauled (apparently) by the previous owner, and I have see the pictures. If there is still no change after reassembly I will do it as you suggest.

Many thanks

Tom

I would like to remove the magneto, but first I must remove the alternator (generator), but I understand there is a special tool needed for this, is that correct?

If so, where can I find one to buy online?

thanks,

tom

Hi Tom

To remove the magnet, you must the generator does not to be removed !
The hexagonalscrew from the rotor has a left thread ! (The screw in the center of the rotor). The rotor must be blocked,
example: http://www.ost2rad.de/images/product_im ... cheibe.jpg
or an old belt

The stator is fixed with two normal slotscrews.

Hi Tom ,
Here is an instruction manual in German http://www.ostmotorrad.de/simson/awo/be ... t.php#a529
You can translate it for example with Google http://translate.google.com/translate_t?hl=de#
