Exhaust manifold Volvo BM4200

[Cruiser_79]

I have an old Volvo loader for around the farm. The exhaust manifold was cracked and the gaskets were gone. There is a Perkins D39L in it, and I thought I purchased a new manifold. Apparently the manifold of a MF168 looks exactly the same, but is mirrored I checked several wreck yards and the internet but can't find it anywhere.. Does anyone know what type tractor/machines have the same engines and where to find a manifold and probably 90deg elbow?

The MF168 manifold has the holes in the flanges mirrored, and when I place it upside down the outgoing flange is at the wrong side.
The outgoing flange has to be on the left side of this picture.

I ordered this one.

can you post a photo of the broken parts please ?

Make 2 adapter plates with studs in the right place for the manifold - and use the block studs to attach it? Would need 4 exhaust gaskets.

our Volvo L30 is a 236t engine, which is the same as a 390t. Had to do the gasket exercise last Christmas, and all the gaskets were from a 390t.

Used to make manifolds out of steel round or just square box it isn't rocket science and often made quickly and easy with no gas flows to worry about, often altering there position, last more or less for ever.photo is only one of three in existence made to special order for the UK so not down to the pet shop for one of those.

Maybe this is the right one? Getting it might be a different matter although having the part number should help...

I have in the last few years been getting Can't again and again, obsolete, but not across the pond, here in mid Norfolk one machinery dealer for ground care large and small finds the parts others can't, It takes lots of time it seems few others will take as it costs them, then huge amount of knowledge as often other manufacturers may have used that part, then theres engines and the like made under license far east, so a compact tractor may have differing names and engines but the same back end, I feel its getting worse electronic displays and there boards fail, I sat in a tractor the other day and it took a little while clearing stuff off the screen before he could start it, won't be long? before they come obsolete so 4 ton of metal being thrown away because of a fraction of a gram of electronic chip has failed, New headlight light failed on my car, nearly £400 worth, think there are twelve leds so controlling those are twelve voltage control units, they cost nothing to produce in large numbers, most likely obsolete in ten years, find any one to repair it? I haven't yet.

A friend of my works in marine engines and stuff, and he knew a guy in the UK that is doing lots of perkins engines. So he got a original Perkins manifold, that fits like a glove fortunately It was approximately 3 times more expensive than the after market version from the MF168, but at least it fits.
Strange that it is quite difficult to get original Perkins parts apparently...

Often parts from original manufacturer over years run down or price goes up according to supply need, the part is used in another application and that manufacturer keeps spare parts on the shelf at cost, years later supplying them still at the same price, again have come across those people finding the spares for a particular machine they supplied being costly got them made far east at a fraction of the cost so hurrah for them looking after there customer.
