Oil Filter Inlet Tube; Group 10-17, Part 647585

I find myself stumped with a puzzle.

It started when I looked up an oil line from Walck’s. This oil line runs from a 90* fitting, under the fuel pump, up to the ‘inlet’ for the oil filter canister. Walck’s website description states for an F-head it is 29.5” long. The L-head version is only 23” long.

I checked the distance from my ‘inlet’ to the 90* fitting under the fuel pump and the distance is between 22-24” and knowing that both engines have the filter in about the same location, I wondered if the longer oil line was correct.

I then looked at some of the available images on the 3B Page. Granted not ALL of the images but some that might help me see this oil line – for verification. I noticed something that didn’t really stand out before. It seems that many images show the oil line run from the fitting under the fuel pump REARWARD then loop up and pass next to the fuel pump and engine as it is routed to the front of the engine. It then turns up and passes by the water pump and water outlet fitting (thermostat housing) before attaching to the canister. It’s been too long since I’ve disconnected everything on mine and back then, I didn’t do a good job of documenting everything with a camera. Here’s some of what I saw:

Piet’s ‘56:

Were all of the F-head engines routed this way or were some early engines routed straight up the front plate (between the fuel pump and front plate)?

There’s a cut-out on the front plate to clear the fuel pump but I see enough space where an oil line could fit. However, perhaps the thought was this tight squeeze would result in chaffing and result in failure with the rubber line.

Any insight or possible reason?

i would be very wary about the repop rubber lines, i ordered that one you are describing from kaiser willys.
it worked great until one day i was doing a check for leaks, and or any rub throughs on my oil lines. i had gently pulled on the line to take a look and the rubber hose slipped right off the hard steel part of the line.
the line under the crimped sheet metal part was not barbed at all, it was simply a straight piece of line under the crimped portion.

now granted it did not leak, even though i could easily slip it on and off very easily.
i ended up bending up a piece of 1/4" brake line and getting rid of the rubber altogether.

the short line from the bottom of the filter seemed ok so i kept it.
if you get a new rubber line i would definitely keep a good eye on it, mine did not become really loose until about 2000 miles of use.

Bob,
I read about this over on the 2A Forum. A lot of owners had catastrophic line failure where the line would just "disassemble" on its own. They stated that the ends on some even required a metric wrench!! Several said they learned that Walck's version was redesigned - due to early over seas versions failing - and now come from a state side manufacturer, and report no problems so far (some running for over a year). I did notice on their website a statement about this quality issue.

I'm very concerned about quality and am wary of any import parts - one troubling fact nowadays. Hopefully, our trusted vendors will continue to filter out the garbage.

I ran the Walck's oil line in question since about 2008 until I put the new engine in this past November with no problems. I did notice both times (I bought the same line for the new engine) that the line appeared to be too long.

Here is a topic that briefly addresses which way that oil fitting below the fuel pump points: http://z4.invisionfree.com/CJ3B_Bulletin_B...?showtopic=4278

I've considered getting the shorter line.

I have a steel line that runs from behind the fuel pump to the oil canister see pictures. I would think that you could get a steel line made or bend your own. Steve

I ran the lines from Walcks and they seem to work fine. I installed them after the metal line fractured after years of engine vibration.

Doug,
Thanks for posting that link. Unfortunately, it contradicts what I’m seeing. To muddy the issue further, I notice from the PM an image of the oil filter shows a clip and sleeve around the inlet hose:

Plus, the more I study the images I’ve got I looked closer at one of Lawrence’s and notice that very clip holding the inlet tube up against the front plate:

I do notice your fuel pump looks different (perhaps single pump with no vacuum?) which may give you more room where your line is running.

BTW, I’m seriously digging that 45* bend fitting on your water pump!


Steve,
That’s some serious line work! I’m trying to go for the original look so I need to confirm the inlet tube's location. Interesting you chose to run the hard line along the same path vs. straight up.

Dave,
How long have you been running the Walck’s tube?

Rus, I thought that my set up was original as I bought this jeep in 1976. I changed the line which comes out of the bottom and goes to timing gear cover,and never did anything except remove the lines and clean and paint them.The only line which I changed was the fuel line which rotted out and I replaced it with rubber fuel line which I plan to replace with steel when I get to it.

No its hose # 647585 @ 27-1/2" long.
The inlet hose uses 2 clips to attach it to the engine.
One clip is located at the front engine plate and the other hose clip is just under the front most bolt of the water outlet.

Rus,

I installed the rubber lines from Walcks 1 year ago and have driven about 1200 miles. They are holding up real good.

Ken,
The Oil Inlet Tube part number is the one I referenced in my topic title – so that checks. Unfortunately, my PM doesn't give dimensions so I'll definitely want to measure out 27.5 and compare to how it lays using the documented routing as compared to Walck's 29.5.

I also cannot find reference to 2 clips. I can only find reference to one clip that could possibly be for the oil inlet line.

GM-128302 Clip, 1/2", for 3/8" bolt.........1

The 1/2" measurement I assume is for the tube (hose) outside diameter. The 3/8" bolt matches the Gear Cover mounting bolts this clip is attached with on the back side of the front plate (see image above).

What water outlet are you referring to for the second clip location?

Measured from end to end the correct hose is right at 27-1/2" long.
The other clip was referred to as a "fastener".
The Jeep part number is #645539 also GM 128302.

It only shows in the 1953 CJ-3B and the 1955 CJ-5 parts lists.
It does not show up in the 11/1956 CJ-3B parts list.
That implies that it was deleted sometime in 1955 or early 1956.

It was attached to the foreward uppermost oil filter bracket bolt.
It's function is was to keep the hose away from the fan blade.
Personally I prefer to attach a clip under the foreward bolt of the thermostat housing.
A standard clip actually fits better at the thermostat location.
Willys SW and PU with Super Hurricane engines used a similar clip located under the foreward thermostat housing bolt.
