Difference between Volvo Penta TMD22L & TMD22P

[superboots]

I am looking at collecting some spare parts for my engine a TMD22P - There seem to be plenty of parts for 22L versions - which ones are compatible with the 22P or what are the major differences. I know the 22P is the same as the engine fitted to the montego car but havn't tried getting spares that way. Don't I need an engine number or registration number for a motor factor to follow up?

Can't answer your question but you might find the full parts lists at http://www.marinepartseurope.com/en/volvo-penta-cat-7744150.aspx and http://www.marinepartseurope.com/en/volvo-penta-cat-7746710.aspx as they will enable you to compare part numbers to detemine compatibility, or otherwise.

I dnot think I can find any reference to TMD22L . MD22L but not TMD22L

Maybe there is only a MD22L -which would the version without the turbo, so I wonder what parts would be different between turbo and non- turbo versions. Looking up part numbers is baffling to me and many VP parts are listed as discontinued - which is another point I grant.

I suggest you contact (pm) skipper stu of this parish. He has become something of a MD22 expert. He wrote the recent boating magazine article about reconditioning an engine as a spare.

The L&P versions only apply to the non turbo engines and designate different HP versions

The basic block is exactly the same as the Maestro, Montego, early LDV 200 van. The horsepower is governed by the injector pump setup. The injectors had the pipe connection on the top or on the side. The ones on the side are allegedly two stage. The engine bits can be bought from www.parts4engines.com. There were various compression ratios but the pistons available now are 17:1.
The fresh water pumps on the Volvo are different to the cars but the same as the LDV one. The starter on the car is on the opposite side to the Vp. The early VP engines had a heat exchanger with top hat rubber ends on, the later ones had a square exchanger with add on oil coolers and intake air coolers piggy backed on. Hence TAMD22 was turbo, air intercooled, whilst the TMD22 didnt have the air inter cooler. All this was to alter the power output quoted.
Basically, the cam belt kit, a montego or maestro one is good, an early LDV 200 water pump is good. Be careful on alternators and starter motors, the VP engine is isolated earth from the block.
Bottom line, because the car bits are becoming very scarce now, better to buy from parts4engines.com or Asap are starting to stock bits for them now. Alot cheaper than VP

Thanks skipper_stu,
just what I needed to know, can I assume lift pump is the same? There was an accessory for top mounted 2nd alternator bracket on the L which was discontinued and never available on the P. I'd like to fir a second alternator above the rocker cover as I have no space on starboard side - can you suggest anything?

The two stud lift pump is exactly the same, loads on ebay. Second alternator? No idea on that BUT I have fitted a Sterling booster to my alternator, works great.
I will look up the toothed alternator belt I use, it beats the std VP hands down.

Looks like generic parts not available - tried all the links. So hope my water pump does not misbehave. Had to change timing belt and tensioners with VP parts - but what would a broken engine cost!

Is it possible then to turn my tmd22 -78hp into a tamd22-105hp by changing the injector set up and fitting a aftercooler ?

 

[superboots]

seems someone did and offered the almost complete engine on ebay for 750 - it was snapped up in no time . How it was working was another matter.

The MG Maestro TDI scrapper engine I bought had the same injectors as the ones in my MD22, this confirmed by Dr Diesel in Oswestry. I believe the extra HP is achieved by using the extra revs that the car was designed to go to. Ours usually max out at around 3000, the car does as below:

"The Maestro's 1994 cc (121.6 ci) engine reaches its peak power of 115 bhp (85 kW) @ 5600 rpm. MG Maestro Torque: The MG Maestro produces torque measuring 134 lb-ft (155.9 Nm) @ 2800 ..."

So, the pump would have to be tweaked, any good diesel shop could do it, a forumite bought my car one off ebay!

VP put an intercooler on the end of the heat exchanger, they just bolt on the end of the existing one.

The car also had an oil cooler, a very crude device, I have that in the garage.
If you did go down this route, dont forget, gearbox ratios? prop?

That's brilliant thank you ! Really thinking about it because I just can't find a tamd22 for sale any where ? Trying to find a second hand aftercooler if you have any ideas,
Thanks for all your info ??
