Base engine for volvo Tamd 41-p

Think 40 series and therefore all its descendants was designed as marine unit.
However suspect all the bolted on bits were sourced elsewhere and sprayed green.
Virtually everything except major components block, cylinder heads etc.should be available from after market suppliers.Even pistons and bearings.

I thought the 3.6 litre originated from a truck engine? our old TMD40A's were I think and our current also old TAMD41A's are the same basic block I believe. I think the manaufacturer does its best to disguise what can and can't be cross matched to after market and/or truck parts.

Do Volvo use other makers engine parts then?

30/31/32 and 40/41/42/43/44/300 Series were all Volvo designed and manufactured.
Some small diesel engines (e.g. saildrives) are rebadged Perkins.
Current D3 is based on a Volvo car block.
D4 / D6 were designed with help from Deutz, manufactured by Volvo.
Base engines for petrols are GM, these days, some older 4-cyl petrols were modified Volvo B-series car engines.
Not sure about the bigger stuff.

Wrong
If the part number is the same the part is the same equally if the part is the same so is the partnumber
The part number also incorporates a source e.g. Parts beginning 8 or 38 are first used in marine applications and if used later in truck applications may be available from trucks on a different pricing structure
When Volvo truck assembly used isolated return electrical senders for petroleum reg tanker chassis the had to buy them from the local marine dealer
 
Im not sure. I still remember the volvo trucks having this engine. Named F4. Quite small trucks. Extreme revs. Even remember Volvo had their first turbo and compressor version for trucks. This might have been the F6 with the lager 6 liter.

Even the prechamber engine was used.

The bore and stroke are the same.

But when it has different pistons, rings, cylinder heads, and indirect injection, I think any notion of it being “the same engine” is pretty much out of the window.

The leaflet attached refers to the D40 engine but the automotive engine derived from the marine
The 40 series was introduced to match the outdrives that had used the Peugeot 21/32 engines
The TD40 was sold as an industrial unit in relatively low numbers. One application was as a donkey engine in road sweepers but unfortunately the fan could end driving the engine breaking crankshafts it may also have been used in construction units.
Volvo at that time and may even now had truck cars construction aero and penta devisions along with corporate brand section that joined up the group strategy and marketing this ment that when the truck engines for example were designed they would take other possible uses into consideration for example the the front end was designed to allow more power to be taken for hydraulics than a truck might require but would be used to drive a winch for a trawler.
In this way trucks would want some input into a relatively light high speed unit such as the 40 series which was designed with an initial marine application
 
I recall some story about the head of Penta and the head of Volvo trucks living next door to one another, discussing over the hedge one Sunday afternoon, and agreeing to combine R&D investment to develop a base engine. The result being the MD40 and the D40. The D40 is a long out of support engine though - I recall trying to source truck parts in the past and gave up.

Maybe I'm getting confused, but I'd be surprised if they weren't sharing such R&D, especially when there were 2 x 6-cylinder 3.6l engines in production at the same time.
 
The td 41 was also used as truck engine. About 130 hp. Its more or less the same engine. TD40 prechamber and td41 direct injection.
They share a lot of parts like timing gear,crank shaft, pump drives etc. Td 41 was also used in some maskines.

It might be a original marine engine ,it was made in Vara Sweden. I still see these old engines operate in quite heavy aplicatinons still performing well. Last year i helped a friend with a td40 with 165 hp in a 21 fot boat doing 30 knots. The engine was running like new. No smoke, sweet sound, no leaks and after tighten up manifoild,full power. The engine must have been more than 30 years.

Had a 1980s Princess 33 with 135HP AQD 40A on outdrives.
The engines were showing over 4000 much abused hours when we sold it.
Only maintanance was fluids religiously changed each year and the odd alternator or start motor biting the dust.
The outdrives on the other hand might as well better be attached with zip fasteners. the number of times they were removed and put back on.
Remember going to look at a P33 with 40A boasting nearly 8000 hours on the clock.
Decided that was a bit much.
 
It seems I was after all on the right lines, the Volvo Marine engines 40 and 41 do share common parts and are in many ways the same base engine. Of course they have many altered parts though for different applications and power needs.
The importance of knowing this is that often more mundane parts such as filters, gaskets, lift pumps, etc cross match to auto/truck with inevitable pocket saving. If I recall correctly i bought 12 glow plugs for our previous 40 engine by cross matching to quality Champion Plugs in the auto/truck side for less than a single Penta one! 12 of theirs was eye watering:disgust:
I also recall in our earlier days of petrol penta inboards needing a water pump for a V8 raw water cooled engine (based on a Chevy motor) and a very honest dealer who knew I was also into classic cars saying the only difference between the marine pump and the auto one I could get from the american car place was perhaps a coat of paint on the inside and £200!
The difficulty is usually knowing what cross references!
