Oil screen

#1

Post by StueyC »

The right case on my motor is 1949 and has no tappet oil screen but there is a hole that is blanked off by a welch plug. All the manuals I have show generator cases from 1949-1966 have a screen. Is it usual for someone the block this hole or were there any motors released by HD that didn't have the screen?

Stuey!

First,
Get a real Service Manual!

Attempting to remember off the top of my head,..
The overhead oilscreen was introduced late in '52, for the '53 hydraulics.
This shot of the '49 prototype shows no boss for a screen well.

The well for the screen was welch-plugged for nearly all 5-digit VIN '65s, and some early '66s.

Can you see your production numbers on the belly of the cases?

Thanks for the reply Cotten. My case numbers start with 249 so it would appear to have no screen although the Clymer manual shows 1948 onwards as having one? I found it difficult getting the lower screen to secure in the case. Did early cases have this screen too?

What would you recommend as a real manual?

Oh, THAT welch plug:

That's not the same gallery as the later overhead oil screen well.

Thanks for clearing that up Cotten. Any ideas on the lower screen and recommendations on the manual?

StueyC!

Uh, "lower" screen?

The only screen that comes to mind in your '49 case would be the bubble-buster inside the cam chest.

And if you are still referring to a Clymer "manual",
Uncle Floyd rolls over in his grave with laughter every time they confuse some one.
He was quite an "entrepreneur", and his successors carry on his tradition. (Anybody know where I can get some late-'60s International Scout light truck emblems?)

There is no substitute for the genuine Service Manual, widely available in re-print. If your machines are a '60 and a '67, I would suggest the later '58-'69 manual, which adds valuable insights for the earlier models as well. Together with the Parts Book, most questions are answered.
The problem is that one never finds the answers until after making a mistake.

And of course, Bruce Palmer III's "How to Restore Your Harley-Davidson" (Motorbooks International) fleshes out the skeleton outline of the Service Manuals with a lifetime of information. Even the bobber-chopper enthusiast will find it valuable, unless his whole chassis is a catalog kit.

The crowning resource you need is this web community itself.
For example, your original valve pushrods most likely have been replaced, and the Service Manual does not address modern "solids".
But a search of this forum for things like "pushrod adjustment" will bring up a wealth of tips and opinions.

Good luck!

Thanks again for the advise Cotten. This site is without doubt a vast source of information and has helped me many times. I usually try to work through problems myself as a sense of self satifaction prior to posting a question but if I'm unsure I will always ask.

I haven't seen reprints of genuine service manuals before so will take a better look for one.

On another topic, do you use gasket sealer on your tappet block gaskets?

StueyC!

Most modern quality gaskets have an adhesive pre-applied.

When I suspect that the assembly may need to be broken back into soon, I use Gasgacinch to defeat the adhesive.

With vintage paper or home-cut butcher-paper gaskets, I use (non-discbrake) grease.
Or sometimes different paints.

I only avoid silicone, or anything that looks modern.

Is that a trick question? Studebaker did not make a pick-up in '39, what they offered was the forerunner to an El Camino; half car/half truck, called it a Coupe Express. And there were no badges on the hood, just some stainless trim strips.

But, they did have an oil screen! :lol:

Happy New Year everyone!!
