Vt190 Cummins diesel in sump

[1950d owner]

Hello im Dave just joined here.

Ive got a 1950d acco truck with a vt190 Cummins engine. It's getting diesel in the sump.

Any ideas or hints tips would be good thanks

Is the lift pump leaking? It could have a hole in the diaphragm.

Gday mate not sure

I think these have 'in board' injectors like the Td5's.. (Can you see the injectors ore are they under the rocker covers?). If this is the case, the O rings around the injectors need changing as they leak after a while..

[1950d owner]

Gday mate gonna replace injector o rings first see how it goes

Gday just wondering does anyone know if the cab on an acco 1950d will go over further for engine removal

[oldyella 76]

You should be able to get the engine out without removing the cab. We did ours a few years ago without pulling the cab off , just forget now but if you take the retaining strut off you may get it up a bit further but be careful it does not go right over. I would put a bit of rope or wire on it to prevent the cab from going over too far. Altough it will take pressure off the springs, as the cab goes over so will the centre of gravity change. I have the problem of a leaking oil cooler letting oil into the coolant and it appears that I can't buy a new one, so looking at pulling it out and trying to repair it. Not looking forward to it. The VT 190 must have been the worst engine Cummins ever made and you have to drive them like you hate them. Best of luck.

Thanks mate do you know if anyone has ever changed out a vt190 for a 555 or a 903

[Homestar]

Both the 555 and 903 will fit, but they are old engines as well. Finding one that doesn't need work may be tricky. What sort of HP are you needing out of the old girl?

[1950d owner]

Would like around 250 300hp if possible do you know of anyone i can talk to about converting

[Homestar]

Not up your way sorry, I know a guy in Melbourne that could do it, but it wouldn't be a cheap excersize unless you had a good condition engine ready to go - the guy I know is very particular about how he does his work - no shortcuts, so he would be reluctant to bung in an unknown condition engine but could probably source something or rebuild something - a rebuild on one of these old V8 diesels is VERY expensive - around the same price as doing a C15 or Signature. Is retiring the old truck an option and buying a half decent second hand one that is in good running order? Would be far cheaper to do this if you can't swing the spanners yourself.

[1950d owner]

Does anyone knows if i did away with the vt 190 will a turboed Perkins fit in without any modifications

[Homestar]

Most conversions (assuming the engine will bolt up to the existing gearbox - probably easy enough to find the right engine adaptor) are going to require new engine mounts, radiator inlet and outlets may be different, if you aren't currently running an after cooler, then that will need to go in, etc. wiring loom to the engine will be different, sump clearance over the front axle will need to be looked at, length of the engine to the radiator - gearbox may need moving, so new gearbox mounts, tail shafts, etc. No conversion will be a straight forward bolt in, there will always be something to do. The bonus of doing one to a truck is that there is generally always a way of sorting things out, but again, if you aren't swinging the spanners it's going to cost you.

Easiest way of checking is to find another Acco of similar vintage already running the engine you have in mind, then going from there.

[Sitec]

Have you looked at/considered a 6Bt? 5.9litre, and anywhere from 130hp to 350hp reliably.. Maybe too small but worth a look.. :)

[Homestar]

Good thought, but it's bigger brother - the 8.3 litre 6CT would Probably be better suited - they were used in the ACCO's for years up until the ISC - the electronic version - was introduced back in 2000 and something - 06 maybe, can't remember exactly.

What's your budget for a replacement?

I hadn't realised Cummins had built a V6.. It'd be a similar size to the V6 Merc engine in my truck.

I hadn't realised Cummins had built a V6.. It'd be a similar size to the V6 Merc engine in my truck.

The VT190 is a V8, similar in design to the 555 and 903.

Short stroke - 3.75" and a bore of 4.625". The 555 took the stroke to 4.125" while keeping the same bore size. The 903 has a larger bore and stroke at 5.5 x 4.75"

All very old engines now, depending on budget there are much better alternatives unless the owner wants to keep it original for some reason. Back in the late 90's the upfit bay at Cummins in Campbellfield was humming to the sound of those old V8's being dropped in the scrap bin for more modern variants. Those days are long gone now, but it used to be commonplace to upgrade the engine your truck.

Just another sign of our throwaway society. Some modern trucks are absolute travesties and start to fall apart only a few years after purchase. Did someone say 'Argosy'...? ;)

Don't bother with the Perkins. Go the 6CT8.3 if you have to repower it. 10spd box and your almost done.
Personally I don't think it's financially viable and would suggest you buy an Account E or G model 2350 if you like the Acco.
