 Topic: 1952 WD oil bath air cleaner
Posted: 25 Mar 2023 at 10:10am |
|
I have thoroughly cleaned the inside (including the mesh screen and the outer/inner air passages) of the oil bath air cleaner. Some how oil is being pulled into the carburater. I only filled the bowl to the fill line with 10W-30 engine oil. Why is this happening is happening?

Use SAE 30 wt and make sure you are not over filling it. Stay below the line. The 10w-30 may be too light if you haven’t over filled it.

Straight 30 will not bubble thru as will the 10W30

i have never had a problem using 10w 30... are you SURE the inside screen is clean ? Not just the part you can see... you need to SOAK the air cleaner in a bucket of diesel / gas/ solvent ... then drain and blow out with air... If you plug up 30% of the air path, the remaining area has to pull MORE AIR thru a smaller section and the extra velocity can carry more oil thru.

Any chance it has a WD-45 engine, or has been rebuilt with WD-45 components? Not sure if the slightly bigger displacement would cause it to suck oil in (experts on here probably know if this happens), but I think the WD air cleaner was smaller than the WD-45. Just a thought for something else to check.

Probably not a bad idea, small restrictions in the air flow path could increase air velocity and vacuum.

Take the wire mash out, soak it in gas then set the mash on fire. When it cools, unroll it and knock the dirt out. Next, cut top of housing off just below where it starts to taper down. Use a wire to clean dirt out between inside and outside wall. When clean bronze top back on. You won't believe how it ever ran before. You will think the mash is going to burn up, but it won't. May have to burn it the second time to get clean. MACK

I dissembled the air cleaner and used degreaser on the interior mesh. I then soaked and "sloshed" the entire cleaner body in a 5 gallon bucket of hot water with Dawn. Did this several times over a couple of days. After that I sprayed degreaser in the air inlet between the outer shell and inner liner. Finally I used a compressed air wand to blow out the interior of the shell. Did a final soak/rinse with hot water and Dawn. This time the liquid was clear coming out of the air cleaner shell.

Engine straight WD except for manifold. It is from a D-17.

I'm going to do this for the Narrow Front 45. Have an extra one in the parts vault, just get it ready then swap it out. I did the first half to the one in the wide front when I put the power steering on. Wasn't aware of there being a second half! It blew my mind how much 'stuff' came off the mesh when I burned it!
I suppose once I get the NF done I could do the one that comes off and put it on the WF. Here I told myself I was going to try to slow down on the projects this year.

Mikey, if you want to run a TEST, pull the rubber hose off to the carb and run the tractor for 30 minutes and see if it runs different.. or take the oil bowl off the air cleaner and run it that way... of course your not going to get any oil in the carb during this test, but you might see a difference in throttle response or power ?
