Verifying actual engine

[rat4spd]

Here are the pics of the tags on my engine. The serial numbers match, the date on the IP, and turbo, and engine match. How can I know if this engine is an LDS-1A?

The tag ...under model no. says LDS-465-1A Rat.

Maybe I misunderstood the question?

Long drive to find out. There must be a way. I understand parts can be mixed and matched, but all my dates are the same. Could it really be an LDS?

What side of the truck is the starter on? LDS would be on the driver's side - don't think it will fit in a deuce that way. The army ran out of replacement LDT's and used LDS's in their place, with the pump settings changed, oil pan reversed, dipstick moved, bellhousing changed, etc.

So....you probably have a LDS turned down to LDT settings - it'll probably run a long, long time that way. If you are tempted to turn the pump back up to the LDS settings (and timing) make darn sure your cooling system is in top shape.

Hope this helps,
David Doyle

I'm just curious as to whether it is in 5 ton form, or mixed and matched to make regular duece power. How can I tell?

I have a deuce here w/a regular LDT engine that I GUARANTEE will beat him! It throws you back & spins all its wheels.

What do you shots of? From what I've read, it looks the same. I just verified my IP does say LDS also.

Here's a couple of the engine and tach. GPS said about 56 MPH at 2500. I had plenty of pedal left.

interesting they have the danger arrow so far up the rpms .

 

[rat4spd]

Red line on the LDS is higher.

 

[tm america]

i know .at least they did it right i would think it to be to lds spec.or they wouldnt need to change the red line on the tach.

Concensus seems to be that it's running at the LDS power level. I'll find out when I get some seat time later and put it under a load. I do remember when driving it home, on the small inclines we had, it never slowed down.

Look under the left front fender on the frame and there should be a number stamped into the frame and the axles and transfer and tranny case should be dated with a tag(Metal) They will be dated . I might be wrong but that is my 2 cents worth from Montana

 

[rat4spd]

This was a repower. The engine is 1981, the truck is 1971
