Hi Muncho
Sadly I Never did find replacement seals.I got a friend to turn 2 steel discs of the right size with a groove in the center of the outer edge to take a large O ring. This sort of works if bearings are not over-lubricated.

@plowmate Did you ever find a replacement for the external lip seals for your Motocart brakes?

We have a Motocart that uses the same the same part number EC300128. It seems external lip seals, with a press fit on the shaft, are much more difficult to find than the usual type that press fit into the housing.

Yes they can be registered for road use, have a look at the DVLA website.

There’s one on eBay. https://www.ebay.co.uk/itm/136250385454
Can they be registered to go on the road?

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.

Andy.

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.
