73 charger - Oil and Temp Send unit location correct?

[rollo1504]

Hey guys!

Concerning location of oil and temp sending units on a 400 4bbl charger ....

Please have a look into the enclosed pictures and tell me if I am right...

a) is it correct that number 1 is the oil pressure send unit?
b) number 2 should be temp sending unit mount point right?

Questions:

1. Is the location of the oil pressure sending unit correct? should it not be underneath the motorblock close to the oilpan or somewhere like that?
2. Looks like the temp sending unit was not mounted to its "original" position? Is there an alternative location somewhere around the block?

Thank you guys

Roland

PS: Sorry for my bad english

1) Is the correct location for the oil pressure sender.

2) Is usually just a plug. On a 400 I would expect to see the temp sender threaded into the front of the water pump housing (see black circle in pic below. location obscured by the fan blade) Earlier housings have the temp sender located on the top left (area circled in red).

BTW, your alternator bracket is all wrong.

Thanks again John!

Will check that out...

For the alternator bracket I have to say thats how I got it.... haven't checked it until now....

So by the way :-) can you tell me what bracket I will have to order? Do you need further pictures for that?

I appreciate that... I owe you already plenty of beers

Cheers

I can take more pics of mine tomorrow if it will help you.

You're actually missing pieces

[rollo1504]

.... So just to be sure the temp sending plug is this one (red circle)...?

Will check that out very soon....

Thanks

Yes

Checked today the engine and luckily could find the temp sending unit.... :-)

By the way.... If anyone needs the 73 charger wiring diagram in colour and high resolution PM me :-)

Have also enclosed the wiring diagram so that you folks can see how it does look like...

I have a 73 400 so will this fit?...

Just want to be sure before placing an order...

Thanks!

It is noticeable you have an originally AC car, just removed

The alt bracket you have is used for AC cars. Its diff because compressor brackets uses the bolt locations used on non AC alt brackets, which is the one he shown on pic on orange engine. You can keep your alt bracket without problem since that won't change anything. Just need to mount the alt like ODZking posted. Using either bracket ( ac or non ac ) alt position will remain on the same position. Is the alt  bracket what changes in front on back of the front alt ear due the engine bolting locations.

The REAL problem you are getting is the water pump pulley which is TOTALLY DIFF between AC and non AC because the belts setup changes completelly. THATS WHY you had to move forward the alt to match it with water pump pulley, but the alt bracket is correctly set on engine.

On AC cars, alt is aligned with compressor and water pump pulley with power steering.

On non AC cars WATER PUMP PULLEY is aligned with alt pulley ( not backwards ), being alt in same location and steering pump runs by itself with his owm belt with crank, not shared

[Nacho-RT74]

Wondering what they did between steering pump and water pump to missmatch them

[rollo1504]

As... I live in central Europe there is no need for A/C in summer for me... We do have hot days as well but not most of the time its just a comfortable climate here so I want to run the car WITHOUT A/C installed....

Also want to remove the heaterbox but thats a thing to take care of later....

Ok I come to the point that many parts at my baby are missmatch or wrong... BUT nevertheless I think I was running.... so BEFORE I will think about correcting all these things I want to fire it up....
Once it runs... then I will take concern about fixing the other things to get it onto the road....

So... in my opinion the next 2 steps to be done are finishing wiring harness, test/replace temperature and oil pressure sending units, connect them to gauges and crank it up.....

By the way... another stupid question:

Is it harmful to fire it up without having the tp throttle linkage installed? I will not try to drive around unless it is installed... Only want to see if engine is running and check timing and carb...

Thank you all for your patience and help

Can anyone tell me exactly what/where to order a mechanical oil pressure gauge inkl. mounting "adapter" for the engine?

Reason: 1. Do not know if the oil pressure gauge in my dash works, 2. dash panel is removed and it will take a long time until it returns into the car... :-)
3. for test reasons I would really like to use a mechanical oil pressure gauge....

Thanks

Ok... everybody forgot one thing! You have an IDIOT light kind oil pressure sender, and you need a GAUGE kind oil sender for the oil pressure gauge the rallye cluster have

The block gets two provisions where the sender location is... one is 90 degrees off from thenother. You'll find a threated plug there what can be removed

THIS IS the correct sender kind ( ilustrated there also the secondary provision for oil already being used for the same you want to use )

About test the gauges on bench... use a cell phone charger and feed the gauges studs. They work with 5 volts and the cellphone chargers sources around that. No matter which lead to what stud.

Ok so I will try to repeat to ensure that I understood correctly 

On your provided picture the "big" device to the left is the CORRECT sender unit for my purposes and on the right side there is the secondary provision which is already linked to a mechanical pressure gauge right?

So then I have to do 2 things....

a) get the CORRECT oil pressure sending unit and
b) find the threaded plug at my engine remove it and install there the secondary mechanical pressure gauge



Concerning testing the gauges..... Thanks for the hint... I will try it soon....

[rollo1504]

... another question...

if I find the threaded nut and I have removed it... can anyone tell me please what kind of adapter/screw I need for installing a mechanical pressure gauge wire?

Just asking as it is very hard for me to understand the american screw dimension/sizes.... 

Thanks

The oil pressure passage in the block is threaded 1/8"-27 NPT (National Pipe Thread).

Thanks for the link.... Is the second adapter (I assume the bigger adapter will be needed to be screwed into the block) a 3/8" - 20 NPT?

Just asking as there is a possibilty to get a oil pressure tester set in europe with several adapters incl. gauge....

Roland

[John_Kunkel]

The 2nd adapter in the kit isn't needed.

[rollo1504]

Thanks, then I will get an oil pressure set here in Europe...
