Only last week I think - it pays to read the forum, even if you don't have a query.

"ardox dypenatran"? Now we're really getting scientific. Looks a pretty neat job already to me..... Interesting option, Les

Re, Dye Penetrant Non-Destructive Welding Test.

You can also use cellulose thinners and french chalk. Rub french chalk into one side of your crank case, where you suspect there may be a crack. Next brush over the opposite side of the crank case with cellulose thinners, the thinners will be drawn into the crack by capillary action. if there is a crack right through the crank case, the french chalk will go a bit darker. The area to be tested has to be very clean and dry before testing.

In the early 80's I worked at a company that made oil coolers and radiators for large diesel engines. The top and bottom tanks on some radiators and oil coolers were made from sand-casted Aluminium. Any imperfections were ground out and welded back up, using the TIG welding process, before going into the machine shop for machining. This was common practice for  most companies in engineering that used a foundry. I guess BSA was no different.

Your cranks do look like they have been welded and ground but I would reckon, the welding and grinding was done prior to machining at the BSA factory. I would say your crank cases will be fine.

Hi Niel,

Good luck with your engine strip down. I will be starting my D7 engine strip soon, as it has developed a gearbox problem and a strange rattle.

I had a pair of D3 crank cases that had been used on a trials bike and had been heavily welded after the case was damaged. Unfortunately the welding contracted and distorted the case out of shape and it wouldn't seal correctly when the 2 halves were brought together.The cases ended up being scrapped. I used them for a time in the college I worked at, teaching welding apprentices.

Hi bantammad ere l nowt that the crown of the weld had not been dressed back so retaining its structure. Maybe if the weld had been cleaned up the joint may have given a little just a through , but point taken regards LES
