Hi all

Well, I tried to split my 125cc  engine cases apart again today with no luck, It has been soaking in 50/50 acetone and tranny fluid for the last 3 weeks, we machined a rod to push the steel sleaved out and they did come out using a press, but the flywheels (crank) is that rusted and frozen stuck onto the alloy casings, it wont move.

When I got the engine it had no barrel attached and the motor was filled up with mud.

We did try using heat, Just in case you where wondering.

Question do I give it away to a boat owner so he can use it as a Anker ???????????? It is just a very constipated frozen chook.

Any ideas? Hansdunno

Hi Sunny

I definitely removed every screw and the 2 steel tube sleeves in the engine mount holes, there is nothing holding it except for the rusted bearings and swollen crank onto the alloy casings.

I suppose I'll just keep soaking it in the hope that it will penetrate through, I am to scared to use a long bar onto the crank (sprocket) nut, to try turning or moving the crank.

Thanks Sunny....Hans

Patience and persistence is what you need, together with regular application of a variable inertia device on the crankshaft ends (ie a lump hammer / mallet. - you can't do much more damage!

Take inspiration from the fact that even if the bearings are rusted to the crank's  shafts, bearings aren't generally "rusted" into the ally casings.

Mainly because it's generally a metal to metal contact and therefore devoid of air to enable rusting.

Here's hoping on your behalf! 

No guarantees of course, but I think you will get it apart eventually.

Have you tried the South African lad's idea of using two bits of studding and two pieces of flat drilled steel plate, undoing the nuts from inside the plate forces the barrel studs apart.

Four now on the road and at least several in bits.

Thanks Mags 1 and cocorico, Making the plates to bolt to the casings is our last resort  as it would probably strip the alloy threads out.

I know, I have to be patient, this is why the motor is in my mates shed, ...As I have no patients and would have hit it with the biggest hammer I could find.ranting

This is also why I started to restore the other 1950 frame just to keep myself busy, instead of throwing the motor under a truck.

Thanks for your help and we will try heat again in few day, I'll keep you posted, Stay tuned and watch the next episode of "one thousand uses for Bantam engines" (like Anker's, paper weights, MMMMMMM, must be more uses)

No no no! Not, bolting anything to the case at all.

Imagine two flat strips of steel about an inch wide and an eighth thick and about 5 inches long, two holes drilled in each about 3 inches apart.

They are laid on their edges in the mouth of the crankcases.

Two pieces of studding  with 2 nuts and  2 washers each are put into those holes with the washers touching the inside faces of the metal strips, the nuts are touching the washers and are on the inside of the two plates.

As you undo the nuts, they push against the washers which push on the plates, which connect against the barrel studs, gradually increasing the pressure on all four nuts and keeping everything square, the cases WILL soon begin to part, they have to, they cannot resist the slow increasing pressure from the studs/nuts.

I made some thin Ash wooden wedges up to split two sets of D3 cases and tapped those in too from the other end.

Be very careful and work slowly, try to keep the split in the cases the same all around.

Saw this on here about a year or more ago and have used this method many times since, it does no damage and it works I promise you. M.

Door stoper, base for umbrella for the beach, stand for shop sign, cylinder can become pot for flowers, piston can be used for braking nuts, and also paper weight (as told)..

Those are some of my additions for the "one thousand uses of -non working- B. Engines".. 
I am thinking of one new use, every time i have a fail with it...ranting

YOU WIN.. Dimitrisy, I think I will climb into the dishwasher myself, If both of us don't get our engines split apart and running properly soon, I think we are catching a touch of Bantamitis (effects the brain, something about sparks and rust apperently) and, We both really have to try harder and put in a effort to turn this forum post, back into a serious discussion. LOL.....Hansout-a-here

Yes you are right :) we may kindly request one good moderator/administrator to remove all out of topic posts, and then go back to serious business...thumbs-up
It's just good to laugh some times, instead of hitting our heads on the walls
