Cummins Engine Model: 6BTA 5.9 M3 year 2000

[Latestarter1]

Hi Latestarter1, are you also saying to stay away from aftermarket parts for the tier 3 qsb 6.7 425?
I’m not in the marker for parts because it’s still under guarantee (so still paying through the nose) but just for future reference.

Bouba,

Not at all Cummins is not ainal about non genuine filters and third party servicing during the warranty period but having said that I would not stray from Fleetgurd filters. Cannot think what service parts you would be paying through the nose for Fleetguard are as cheap as anything else on the market. Sherwood pumps can be an arse however ASAP Supplier Sherwood parts far cheaper than Cummins the are alternatives to the stupidly priced stretchy belt. I have new QSB Sherwood pumps old stock for £350. CAC Zincs are far less expensive from AH Latham as they sell the zinc only whout the brass nut. IF the motor in question IS a QSB5.9 and CAC wrecked by neglect blaming it on defective core then replacing first class Serck unit with Bowman rather than repair the original unit leaves me uneasy not to mention Bowman Delta T will be far less than the Serck unit.

Helloooo P, welcome back!
Where have you been hiding lately? We missed your contributions!
For instance, I'm sure you could enlighten us on a hearsay about a MAN/Cummins partnership, which we debated in the last posts of this thread. :encouragement:

Mapis, Never is a dangerous word let's say unlikely.

MAN and Scania both have VW parentage howver the two engine divisions share little, add to that Cummins have had a working relationship with Scania for over 25 years though Holset and development of the HPI and later XPI fuel system and I remember that a legal agreement was put in place to prevent sharing of HPI/XPI with MAN.

I cannot share any more detail but Scania have been jointly working with Cummins on a new engine for some time after rejecting a similar program in partnership with MAN.

Cummins QSB/QSC/QSL marine line is in good shape, QSM11 requires replacement, X12 would be perfect, super light platform good for 700 hp, QSX 15 marine is almost ready however somebody decided that commercial market was a priority making it a lighter less expensive alternative to QSK 19. QSX15 should have been QSX 16 harware has existed for years when I saw marinisation was based around a dry exhust manifold with commercial ratings between 450/700 I told people they were nuts. QSX16 could have been 700/1,150 Hp leisure rated motor with wet turbo, lighter more compact package than CAT C18, but no marketing folks got cold feet. When QSX15 is released I will not be interested, Tony Athens has already told Cummins he will stick with CAT C18 do not bother offering me a field trial unit..

If Cummins ever gets around to doing X12 as a marine engine could be absolute winner, do they have the will, I doubt it..

Thanks for that, I’m about to have a stupidly priced 200 hour service here in the South of France. After that I’m hoping to do the Cummins course (as recommended by Piers) and then do my own service and source my own parts. If you could do us a favor and stay on the forum for the next ten years, I’d appreciate it

Thanks P, interesting overview as always.
Considering that the MAN V8/V12 blocks with the "old" 128mm bore but the newer longer stroke have been around for some 8 years now, I take it from what you are saying that Cummins block they actually aren't...

This may be the "communal engines" they are hoping to develop as world engines, basically there are a number of interested parties and not just Scania, MAN, and Cummins who are looking to develop a platform for future engines which will be core engines and standardised so any of the partner companies can use the core engine and manufacture it anywhere in the world, with this platform engine they are hoping to reduce engine manufacturing costs by a claimed 25% by having the flexibility to produce engines and engine components in the cheapest parts of the world and have the flexibility to switch production between these areas within a month if another part of the world can do them cheaper.

Sisu, John Deere, Volvo, and MTU have also been linked to this project as well as others.

I was party to all that, however we could not get past the first hurdle, to agree an optimal bore/stroke ratio which suited each parties emmisions solution. Once discussion bogged down in intellectual design rights and other legal issues everything fell apart ..

Now China is proliferating engine designs all spinning out of control..

Good to see you back on here Paul .

How true, but it also depended which side you were on and what interests you had for your particular agenda.

Issues arising were to be discussed and solutions found, but instead there were just several parties looking at their own benefits, usually to the detriment of everyone else.

Positively +1.

Land Rovers with 6BTA's dead common now....But getting popular in Madza drift cars..

I have a very early 6bta 5.9 rated at 180hp at 2500 rpm which was a full recon done at Thurrock and it has been in my boat for 14 years now and has never let me down.
the only slight problem in the early years was the governor sticking in the bosch pump
which was cured by adding 2 stroke oil in the diesel.

Your thoughts please.[/QUOTE]

Guys under Steve Moss at Cummins Thrurrock were spot on, did not know of them rebuilding any 6BT180 CPL742 marine engines. Think Steve sold an automotive 6BTA 180 CPL 834 with a Bosch VE fuel pump however that engine was marinised with bits from Lancing Marine with their topsy turvey turbo arrangement and they must have been having a particularly bad brainfart day when they did that one, so doubt if that engine is still around..

As to fuel adulteration I do not condone it and the engine in question has the Bosch VE fuel pump whose governor is geared up to engine speed and governor 'sticking' is not a known failure, only time VE governor goes unstable is when you push it to high delivery rates, in fact hot rodders can often loose high idle governing completely with their screw twiddling.
