Grahame , with all due respect , when you replaced your sheared B&S key did you just hand tighten the flywheel back on , or apply the correct spec of torque , I suspect the latter. Looking at the photo of your 2A key , it seems obvious to me that it is the result of damage caused by running with an incorrectly tightened flywheel.I’m certain that…[Read more]

Grahame, I wouldn’t worry about reinstating how you took it apart, I look at it as some idiot of an idea to cause other issues when in standard form it would be impossible to get. I have seen this before like a lad on the shop floor knew what he was doing wasn’t quite the ticket but expressing his opinion gets told off from above. A certain…[Read more]

Here are the photos of the sheared Villiers pump crank after a stone came through the suction hose and locked the impeller. Also the 2a grooved key and a cropped image of the bolt threads showing the original paint on them.

The clean cut on the crank vividly demonstrates what can happen when an engine suddenly stops stone (pun intended) dead and…[Read more]

If you google Sheen Flame Wand you can still get all the spares and the operating instructions as well.

David , you’re correct, by Grahames admission the flywheel nut was only “hand tight” if it had been run like that it would not have lasted , the key would have shattered , resulting in untold damage very quickly indeed. JAP2A keys were never meant to shear , a steel key on a steel shaft in in steel housing is so obviously a recipe for disaster if…[Read more]

Grahame, I would restore to original spec so wouldn’t cause other issues, not a modern? bodge up of an idea, flywheel, locktite and fail safe? key with a nut locked with a roll pin as couldn’t see that saving damage as with speed comes inertia. crank with its assisted flywheel with locktite and safety shear key don’t think parts would survive. I…[Read more]

Köszönöm Nagy segítség lenne.de úgy a postaköltség lenne nagy.megpróbálom az eladót meggyözni hogy küldje el részemre.

I’ll have to wait for an accurate close-up of the key before passing judgement. No felt seal present is a further indicator that your engine has been apart before and been tampered with.

H7 is a transition fit, where it’s not a sliding fit, but not a press fit either. The flywheel should fit over the shaft and come off again with very little effort. But have some resistance to rotational turning.

There was no felt seal around the edge of the stator plate.

Believe the engine cowl has never come off since it left the Alcon w…[Read more]

Remélje, hogy teljes visszatérítést kap a kézikönyvért. Ha bármiben tudok segíteni, csak kérdezz. Tagja vagyok néhány Facebook-csoportnak, a tagok gyakran kínálnak kézikönyvek pdf-változatait, hogy segítsenek egymásnak. Postázhatnék valamit, de a motorok ritkák ebben az országban, úgyhogy szerintem nem sok van a kézikönyvvel. Kipróbál…[Read more]

Igen a legtöbb motort Németországban adták el.találtam az eBay egy eladó Tecnamotor műhelykönyvet az Egyesült Királyságban 10 fontért de sajnos Magyarországra nem küldi el az eladó. Pedig pont 1983 szeptemberi kiadású.ami a Tecnamotor első éveit tárgyalja .sajnálom hogy nem tudom megvásárolni.

Grahame , one more question , and it may sound off topic , when you removed the flywheel , was the large thick felt seal present around the stator plate.

Andy.

H7 h6 or js6 , forgive my ignorance , but what exactly does that mean.

Andy.

Sok sikert a javításhoz, és remélem sikerül újra rendesen működnie. Nincsenek brosúrám a Tecnamotor motorokról, ezek nagyon ritkák az Egyesült Királyságban. Ne is gondold, hogy láttam egyet. Köszönöm szíves prospektusajánlatát, de csak az általam birtokolt vagy dolgozni fogott motorokról van és kérek információt. Tartson naprakészen minket…[Read more]

Am thinking very much along the same lines. The pulley should be done up tight against the flywheel, the roll pin prevents that. There is a strong possibility that if it is pulled tight it will pull the crank slightly towards the flywheel end. Am going to grind in the valves, so the stator plate has to come off. Will also get the deposits in…[Read more]

Grahame, I have an idea what someone has done, the flywheel nut should be done up quite tight without the need of locktite, and with it being held in position with the roll pin and flywheel locktited sort of sends shivers down my back. and it could be penny has dropped. Right the crankshaft should be pulled up tight against that mag sides bearing,…[Read more]

Grahame , it would concern me when you said the pulley came of by hand , I can’t help but think all’s not right somewhere and would lead to flywheel/key/ crankshaft failure.All the 2As I’ve worked on the pulley tightens right up , and requires the impact gun to undo.
The points gap is usually stamped into the points inspection cover , I would…[Read more]

If using Windows on a PC, the default program will have a slider in the bottom right hand corner of the monitor with a – on the left, a + on the right. Move the slider to the right to zoom in. Alternatively, with the mouse cursor over the image, roll the mouse wheel up, away from your hand.
