When I rebuilt my 1916 engine and put the fan back on, I noticed that I had a tight fit between the grease fitting and the engine block. It is near impossible to get the grease fitting off and on due to the lack of room. Should there be a washer between the timing gear cover and the fan arm bracket?

Sorry, I will try to add a photo that actually looks like a photo.

OK, obviously I cannot post a photo. Any help with the fan problem will be appreciated.
Here is 2 photos of my fan mounting (1915). please excuse the mess but I am dealing with a upper hose leak right now.
I usually have to loosen the mounting bolt and back off on the adjustment bolt to allow the fan to swivel down enough to grease it thru the zerk fitting.
Does that help? If not maybe you can use my pics to describe your problem.
Bud ,the grease zerk does not belong there. You must have a ;special grease cup that also acts as a lock nut for the fan shaft. it has female threads.
It should look like this.
The 1914 - 17 used an unusual aluminum grease cup originally. I don't think any of the grease cups would have been brass in 1915 on the entire car.
Bud's grease fitting is a later addition. are you having trouble getting the grease cup apart or do you have a grease fitting similar to Bud's.
OK, I'm going to try one more time to display a photo of my grease fitting. If it shows up OK, you will notice it almost hits the block. If I add a washer behind the fan support arm, it will move the whole thing forward slightly and should give me the added room I need. Hopefully it will not affect the belt alignment that much.
Let's see if the photo shows up this time.
If you look at Royce's grease cup (and mine without the added zerk fitting), you can see that they are shorter than yours. Perhaps you can find a similar one.
Any washers you add should be with the intention of lining up the fan belt with the pulley as perfectly as you can.
I would solve the clearance problem with a different grease cup.
I think your grease cup is cross threaded and not screwed all the way down. You need to take the fan and fan arm loose and fix it.
Two things I would address. One is if you add a washer it will also move the fan pulley forward. You need to keep the pulley in line with the crankshaft pulley, or the belt will run off. Do not add any washer unless the fan pulley is now too far back.
Other thing. Can you remove the cup when you take off the belt and move the arm? If you can do so, that would be one way to grease that bushing. If you can find a shorter grease fitting like the one posted by Royce, do so.
