4x4 Australia article on CRD problems incl TD5!

[PhilipA]

Well the, what is the word morons? have a special feature on CRD problems in the latest issue.
They include TD5s in the list of CRD engines.

At least they didn't show the TD5 as having any common CRD problems.

I wonder why?

Could just be that TD5 is not a CRD engine. They say it has a Delphi system, when only the injectors are Delphi AFAIK.

Wait till they do a write up on independent suspension. The D2 is terrible in that department [emoji33][emoji12][emoji2]

I thought it was a LUCAS developed fuel injection system.
I've just had mine out and I could have sworn they were marked LUCAS.
I've heard many people call it the first CRD. I think it's easy to to confuse a common fuel gallery as a CRD.
So what if the article got it wrong. Those that know, know! Generally a very reliable engine. As with any older motor, have to keep on top of servicing.
Best oil, best filters, best chance of a long life.

to any 4x4 action journos reading this .... when are you going to do a write up on td5's real bugbears you know .....snapped timing belts, problems with having to shim the valves ( all 20 of them), not to mention the balance shaft issue.
Contact me here and I'll tell all;)

last time I checked td5s don't have belts !!!!!

[Graeme]

Nor shims for 20 valves nor a balance shaft....

your right, it doesn't have belts, its only got the one.

you have no idea how frustrating it is trying to install a balance shaft, its bearings then timing it in properly and that's assuming you can get your hands on one.

I've still never managed to get the common rail-injector line union nuts to seat correctly.

as far as engine goes its probably about on par with a 4bd1-t no wonder ford discontinued it.

excellent I should've known you would have these bits in stock,along with humour bags .....apparently some vendors are nil stock atm:angel:

Despite all of this, they don't use much petrol.

Hi Guys, am I missing something? ( I like to keep abreast even though I drive a tdi, :D) A Td-5 is common rail diesel or not? My understanding is "CRD" is a generic term for diesels that used a common very high pressure "rail" , and the fuel injectors connected to it are "fired" electronically. can you explain ?,
Common fuel gallery ? cheers simmo
PS I think the TD-5 is fine engine

[sierrafery]

IMO there's a quite big difference between a CRD and a EUI(PD) engine like the Td5 is, especially in the fuel delivery system and management area where they are completely different... mechanically i'm too dumb to make statements

[Graeme]

The TD5 has a low pressure fuel feed to its 5 unit injectors. Each unit injector has an internal pump driven from the camshaft to produce its own very high pressure. The engine does not have a high pressure fuel pump supplying high pressure to a common rail to each injector.

Does it start with E and end in G?

After PhilipA correction, I removed the word 'other'.
I used to enjoy reading the publication for their inaccuracies and assumptions (which is more of a reflection on me I guess). Booster leaks on the clutch system was a classic; how to adjust points on your vehicle just reflected what old vehicles they thought everyone drove. They struggled to spell electronics let alone explain them; I think they were afraid of them....

[PhilipA]

BTW I quoted the wrong magazine. It is 4WD Action which is even more predictable.

Why read about nasty td5s when you can read about hektik 200 series croozas with triple chips and 35s.
**** yeah bro.

Most of the posts in this thread are posted with a fair deal of sarcasm, jest humour or all of the above

I'll take the funny hat off for a bit and put the greasemonkey hat on for a minute

Common Rail Diesels work on the same principle as older petrol injectors they are fed fuel at injection pressure and then electronically opened/closed

The TD5 is a unit injector system, all of the injectors are fed fuel at a much lower pressure and then each injector has its own integral "high pressure pump" that raises the fuel to injection pressure. the TD5 is electronically controlled by means of a solenoid operated spill valve and the older school version of it is done with an old school mechanical rack operated spill sleeve.

As its not a CRD the TD5 doesnt have common rail to injector unions, because its a very well made engine it uses a dual mass flywheel and cylinder balancing from the ECU to smooth out the crank vibrations along with the harmonic balancer on the front of the crank so also doesnt have balance shafts or bearings, hence being a real pain to try and fit and impossible to get. It does have a belt but its the serpentine belt up the front it uses a timing chain for the valve gear for a few reasons
The not insignificant torque loadings the injector lobes exert against the timing setup. would have eaten a belt
The impulse loading that would have put onto helical cut gears and subsequently the thrust bearings for the camshaft
The distance from crank to cam would have involved multiple gear steps compounding the above problems.
Square cut gears would have reduced impulse but would still need multiple steps and would have been very noisey.

It is my very favorite electronic engine to work on as you can diagnose the engine without a computer in the defender guise and still get it right about 70% o the time in the discovery manual version and have a near enough 50/50 shot in the auto disco.

In my book if asked if I wanted a suzi 4bd1-t or a td5 as the power plant it'd near enough be a coin flip as to preference.

heres a quite word on the 4bd1 so you can have a fair comarison (http://www.aulro.com/afvb/general-chat/59740-word-isuzu-3-9l-4bd1-4bd1t.html)

...you forgot to add because they are both such terrible engines......love it! (-:

[Jazzman]

I still found it ironic they published this issue the month after my engine decided it needed rebuilding.
