N.A. Diesel in North American Series Trucks?

[David Harris]

Be careful what you are reading, imperial MPG is very different.

Those old indirect injection naturally aspirated diesels arent that efficient. A 200Tdi in a properly geared Series will brush up against the upper 20's but that is a whole different animal.

Could have been the 2.5L they were quoting, which shares the design with the 200 Tdi doesn't it? Good point on the imperial conversion. That would drop the mpg down to the 22-23 mpg range. Doesn't the petrol get in the teens? If so there is still some economy advantage to the diesel.

I've owned a 1966 diesel 109 station wagon since 1978 - it has over 375,000 miles on it. I rebuilt the engine at around 200,000. It has the original 2.25 liter diesel engine and a Fairey overdrive.
Max speed is around 68 mph but its a LOT more comfortable at 55-60. It will get around 25 mpg at that speed. I did balance and blueprint the engine when I rebuilt it. Its slow but usually dead reliable and great off road (if a little smoky).

I would guess that the overdrive makes a big difference

Searched around a bit and can't find a definitive answer to this: Did original North American export Series trucks come with the normally aspirated diesel as an option? And secondly, if so, could it be had in an 88? Anyone here ever drive a stock 88 with the N.A. diesel? Impressions?

Thanks,

David

A Friend in Colorado will have a great little 88 for sale in Colorado. Wonderful patina and diesel - before he got it was a 1 owner truck.

On road MPG or off? On road carefully driven a well tuned 2.25 petrol can get high teens sometimes even higher. Go offroad all day at low speeds and the diesel's advantage widens.

I don't know anybody who knows a whole lot about the old CAV rotary injection system but single barrel carbs and points are pretty easy to figure out.

They were used on a lot of diesels. Any good injection shop shouldn't have any issues servicing them.

X2. Find a diesel shop that tunes injection pumps all day. They should have someone there that knows what they are doing. In fact, just about ANY diesel should be taken to such a shop to be tuned every once in a while.

I 100% agree with you guys in theory, but have you ever actually taken a 1960 Land Rover diesel to an injection shop and they were able to successfully work on it at a reasonable rate? I have not but admittedly have not tried either, I suspect it could be more difficult finding a willing shop (regardless if they had the knowledge) than just opening up the phone book.

Nope. 200tdi was a redesign. Turbo killed the 2.5 motor more or less. Changed and upgraded the block and pretty much everything else...

Yep. Club member back in the day brought one to a specialist and gave him a parts source. No issues.

2.5 and 200Tdi share the same block design but the 200 has an added aluminum girdle bolted on at the oil pan.

They also share the same timing case and belt setup.
The biggest difference from 2.5 turbo to 200Tdi is the alloy head (all-new casting design but carried over the same cam, and intake/exhaust setup), and direct injection system.
Really the 200Tdi is just another evolution of the 2.5 which was an evolution of the 2.25. Its amazing how many components are shared (and interchangable)

Yes.
If you can't find a place call a MF dealer, many of the MF's used Perkins engines that used the same pump design. Or just call a Perkins dealer.
If you mean the pumps and injectors. For setting the timing you can always buy the tools, Dingocroft sells them.

If you actually found a running 1960 diesel, I would be seriously impressed. The 2.0 litre diesel is extremely rare in running condition. I have seen one (which then promptly died and was replaced with a 2.5 NA diesel) and know of one other. 2.25 diesel is a completely different story.

As far as having the pump serviced, I club member had his done at a local diesel place without issue and the UK places have rebuilt/exchange units.

 

[Antichrist]

Yeah, not a pump for a 2.0, a 2.25.
I have a 2.25 in my lightweight and two more 2.25 diesels in my garage, one with a Zeus timing set.
