What was the process involving rotating a batch inside an enclosure? I thought it looked like some form of heat treatment.

I assumed it was shot blasting given the surface finish that came out.

You saw the shot being poured in when the bag was cut open.

Curses beaten to it

Yes MichaelG, of course I saw 'Belarus' on the box, but your post doesn't answer the question

Does this help explain things further?

It is possible these three throw crankshafts are for a 3 cylinder tractor engine, they seem quite common in some places.

My farmer friend has one.

It looks like the old Brit stuff is still popular in some places because it's relatively simple and easy to fix/maintain

edit: and it has a deluxe seat too

"The Company has formed joint ventures in several companies to facilitate local manufacture, often to get round import restrictions and or rules on local content. "

So if your stuff is simple enough you can build it in-country with basic industrial tooling and take a cut

Sorry, John … I didn’t realise that your comment “Not sure what the Belarus connection is“ was an actual question.

Being the first person to mention Belarus on the thread … I assumed you just wondered where I got it from.

I think Bill Phinn as given you the information that you actually wanted.

Despite all the modern manufacturing tecniques ,L/R Discovery 6 cylinder diesel crankshafts break all to often , new engines are well over £10k,

[Ady1Participant @ady1]

Old Discoverys sound like a bag of spanners jumping about

Yes Andy, hammers and bench press. many years ago watched in horror as a "technician" inserted the outer race into my wheel hub with a hammer. He was standing next to the bench press. Back street garage? No, VW main agent. This was fourty five years ago, when WE did it properly.

Regards Ian.

Probably 1970 … we toured the BSA motorcycle factory, where they were building the ‘triples’

I watched in amazement as the chap installed the crankcase main-bearing with one deft blow !

Sounds like 1950s piecework

Why take 60 seconds to press one in when you can whack 3 in at 20 seconds a pop

[Howard LewisParticipant @howardlewis46836]

Unfortunately, the back street manufacturers, do not have the drawings, or technical knowledge and Engineer back up to make the part correct to spec. When the thing fails early, the engine OEM gets the blame for some substandard part!

The quantity being produced suggests a steady market for replacements.

We found some "Replacement" lift pumps that had carefully copied a defect that we spotted early on and eliminated from genuine spares. Often these pirates do not really understand what they are making, and so proper heat treatment or exact material composition tends to be ignored.

In a market with no previous experience, an engine that wears out or fails after 500 hours is thought to be the norm, rather than 5 or 6,000, hours before needing even a minor overhaul for a genuine article.

In such an area, anything that is more powerful than a donkey, and can carry 3 people, and their goods, to and from market without getting tired, is considered to be an improvement..

I have seen a pick up so overloaded.that the front wheels left the road at every slight bump!

Remember the single cylinder tricycle truck being loaded to take away the finished product, in the video!

A VW Beetle started from cold by lighting a fire under the sump!

A tractor, power tested by counting how many bricks, on a pallet, it can pull up a hill.

Parts joined using different threads, "But, it's got a thread on it" (1/4 BSP onto M12! )

Different worlds from ours.
