Deuce up date (what I did on my Deuce today)

[CHIEFSONN]

Yesterday was a good day up here in New York, I had plans to go out a change my fuel and air filter and to see if my fuel pick up / transfer pump sitting on top of the fuel tank was working on account i could not here it the other day. as I had just purchased this vehicle last weekend. I was able to do so. first i changed out the air filter with the correct 400 cfm air filter as required. then it was climbing under the truck to start the replacements of the fuel filters.I removed the primary that had been changed over to a spin on, filter was showing signs of rust having been in there for the period. as i moved to the secondary and tertiary filter this showed me how well maintained the fuel filters had been maintained. these filters were of the stock type. my first attempt was to drain some of the fuel from both but no fuel was to be drained. so i then removed the top nut securing the fuel filter to it housing, and lowered it into the bucket under it. dumped the fuel and pulled out the filter yikes, looking inside the empty canister was about 1" of mud. with that canister marked I removed the third and that one was not as bad,maybe 3/4 1/2 " of mud. I then removed all the scale and mud build up from inside the canisters ,also removing the drain valves and cleaning them removing the build up from inside.I then installed the filters into the canisters.the gaskets that came with the fuel filters i placed around the canister and hit it with some heat from a blow dryer,I found them to be a little on the smaller side before stretching them with the us of heat. I then coated the gaskets with grease and placed them in there grove followed by each filter being installed an secured.I then had my son listen for the fuel transfer pump,no sound but the sound of fuel coming out from the drains on the second and third fuel canisters.once tightened there was no more signs of fuel leaking. I then opened the bleeder valve on the top of the fuel filter housing and bleed out the air. so now I know the fuel pick up pump is working my filters are clean along with my air filter.

G'day everyone,....


Sounds like a job well done!

At least you have the satisfaction of knowing that portion of your Deuce is sorted out and working.

I guess your next job will be an oil/oil filter change?

Yes that is on the to do list for sure,I want to do a maximum no load test to see where I stand with my fuel pressures, and then go over my oil pressures,it remained low when driving @35 psi.maybe restricted oil filters or restricted oil pump screen ? any suggestions on what to do in this situation.

G'day everyone,.....


You can check your oil pressure sender to see if it matches the gauge, I know there are 2 types of gauges and if you have the higher pressure gauge it may read low.
You can also check the condition of your oil, if its at the end of its life when t get hot it thins out too much and that can result in low pressure.

Other than what you have mentioned you'd be looking at worn out bearings,.... and I am sure you don't want to go there.

You can also do a oil analysis. Most truck shops can supply the test kit and have the test done or you can use a mail in service like this. FYI I have no interest either financial or otherwise in this company.

G'day Aussie with my never owning a deuce before what do you mean and how do I go about checking it out. DieselBob sent me a link to have my oil tested at a lab.
(1) you had mentioned to check my oil sender, is that what is called oil sending unit?
(2) how do i know weather I have the Higher or the lower oil pressure gauge.

 

[CHIEFSONN]

Have you used Blackstone-labs DieselBob I just sent for there free kit.

G'day everyone,....

G'day Aussie
(1) you had mentioned to check my oil sender, is that what is called oil sending unit?

Yes.

(2) how do i know weather I have the Higher or the lower oil pressure gauge.

I believe it should be marked on the unit the pressure range, you just need to make sure your gauge matches that.

G day Aussie thank you for your knowledge information and direction, I will give them a look over when it stops raining,That should be Wednesday,Thursday ? what will i be looking for that is going to match and where is the oil sending unit located.

You could always replace the sending unit on the side of the motor, above the stater with a pressure gauge. That will tell you the correct numbers.

 

[CHIEFSONN]

ok thanks

 

[Aussie Bloke]

G'day everyone,....



The oil pressure sender is on the rear right hand side just rear of the turbo.

It will have the either 60 or 120lb stamped into it, I was looking at pictures of them last night to confirm.



Aussie.

 

[CHIEFSONN]

thank you all for you time and I will give it a look at tomorrow on the account of the weather.

Today's update is I was able to get out and remove the oil sending unit,and found it to be 120 lbs part # ms 24539-1. and on the face of oil pressure gauge it reads 0-60 and in small print is marked as part #ms 24541-2 and the motor I have is a LDT 654-1D so my question is this gauge and oil pressure sensing unit capabale for each other and for this motor.

eastern supplies & equipment co. have oil pressure sending units part # ms 50040-2 for the m35a2 & m54.

1. The in-tank fuel pump is available on a popular auction site for 50 bucks, assure you put a new hose on it too. I bought so many have spares, write if you need one.
2. Take the three piece tunnel covers off then you can see and work on lots more stuff. The oil pressure gauge is right in there. Also lots more stuff you have to check.
3. Don't guess, just read the pressure. Install a fuel pump out-put pressure gauge right at the tank.
If necessary I will go search all about that in the posts. Knowing the pump actual output pressure at all times makes life easier, cost about 5 bucks.

pictures are where to put a fuel pressure gauge

G'day everyone,.....

Today..... I was able to get out and remove the oil sending unit,and found it to be 120 lbs part # ms 24539-1. and on the face of oil pressure gauge it reads 0-60 ...........so my question is this gauge and oil pressure sensing unit capabale for each other and for this motor.

You need a gauge that reads up to 120lb to match the sender unit or replace the sender unit with a 60lb marked to match your gauge.

Easy.

G'Day Aussie you are correct the pressure range is stamped in at the top just under the rubber seal. so what I have is a 120 sending unit with a 0-60 oil pressure gauge, I will be picking up a 60 psi sending unit to match.

For anyone interested the part # for the oil pressure sending units are rated @ 60 psi is # MS 24538-1 and the one rated for 120 psi is #MS 50040-2

Today I tried to install a pressure gauge in to the in tank fuel pump as shown in post 15 by frank8003,but I had the Allen key brake in the plug that I was trying to remove so that I could install the 1/8 elbow to mount the gauge. so after that had happened I decided to remove the pump and work on it in my shop, so I disconnected the electric connection and fuel lines, wiped the tank clean and removed the screws but to no avail I can't pull her out.It is a very tight fit with the hose that I also disconnected at the top. what I had plans to do was once I had the pump removed I would drill and tap a new hole into the top and then install my gauge...? is there a trick to this (removal of the pump from the tank). with the time I had left after not being able to install the gauge I decided to remove the batteries from the truck,cleaned all the post and have them charging out side. I will next I make sure I have a nice clean ground on the frame. any tips on pulling the fuel pump out of the tank will be greatly appreciated.

 

[frank8003]

Got all the screws out, electric disconnected, and if it is stock pump then the hose is holding you up.
picture is it as mine came out and (all new, 60 bucks) is what went back in.

Use hose that can remain immersed in fuels!

That painted over and in there for like forever, hex female 1/8" NPT that one must remove to install a gauge some find to be a pain. Use the very best steel hex wrench and soak the thing in Kroil or your favorite mix. Disassembling stuff is an art at times, sometimes a one time deal. Grind the really good steel hex wrench a bit so end is dead flat and clean out the driven point and assure you have positive lock. Stuff has to be cajoled sometimes, be one with it.
