The second issue is that hole on the right also feeds the top end which then drains down and oils the piston skirts. I plan on running exposed valvetrain which is an issue for another post but for the sake of this post I could probably just T off another external line to the top end and bypass the passages in the stock cam cover all together? External copper lines = awesome anyway so win win.

From what I can tell all the cam bushings all get splash oiled so the only real oiling issues are listed above.... I think.
Would this give you enough to lube the wrist pins?

I'm with Jaw's, this is going to be an epic build, please include it all in here so it doesn't get lost.

I'm thinking the external lines would basically just be replacing the internal passages in the stock cover so it should still oil what it's supposed to oil as long as I use the correct size tubing.

Question for you Magnum 45 guys. You use an Ironhead crank in a Magnum 45 correct? so does that mean the pinion end that goes into the cam cover is the same or does it need to be modified?

although the pinion shaft is not the same overall i believe the end into the cam cover is the same diameter.... someone here with a 45 crank out will be able to measure it to be sure....I didn't use an Ironhead crank in my MAgnum I used a brand new 45 crank....

IF you are doing external lines, why not add piston squirters to help with lubing the wrist pins? Would this not work with case scavenging? Probably not even an issue really, just kicking this around in my head outloud er...typing.

would it help to make a aluminium template of the XL cover then screw it to the WL cover , you have inside view of the differences

cool thread

Few things I learned tonight....

I was able to take the #1 cam bushing out of the XL cover and put it into the WL cover. problem solved.

New probl.... I mean solutions...
The pinion shaft on the XL is about 1/4" longer and is a smaller diameter than the WL so hopefully I can do the bushing swap like on cam 1 and taking 1/4" off the end shouldn't be a big deal.

I'll need to machine the WL cover to fit this bushing for the idler gear.


Cam 2 bushing is set in about 3/16" on the XL so I'll have to mill down the WL cover to match. This will also align the gear in the mag hole.

XL


WL


I think that's it for now. I'm sure there will be more "solutions" tomorrow.

If the sportster has its own oil pump separate from the timing cover then why not take the oil from that 1st hole and run it thru a proper remote mounted oil filter and then back to the engine via the second hole !

A plate to accomplish this shouldn't be too hard to create !

I think the remote oil filter goes in-line in a different part of the oiling system. Probably a few of those lines coming out of the pump that I can't remember where they go.

the other MAGNUM!... I like that.

It probably would have in the beginning but I'm past needing that at this point. I also have an early and a late model XL cover to look at and measure.

FWIW...My XLCH has never had a Filter...certainly Not a Proper one.
I have only ever had Poblems with external filters excepting on O.E. Applications...Hate to see something like a Cheap ass spin on filter affect this project.

damn, you're making a sportster look a hell of a lot cooler. Is there no room to make an internal oilway instead of running an external line?

We have met at the AMCA meets before, If you need any help with the exposed valve set up, let me know.

Yeah, your Mag 45 inspired me to give it a try. I've been meaning to contact you to see how yours is holding up. Any problems with rocker tip or push rod tip wear? If I recall you only had grease fittings for the rocker shaft.

Last night I machined down the cam 3 hole in the WL cover to match the XL dimensions. All 4 cams and the idler gear fit great now.



My next issue and possibly the biggest one is the pinion ends are totally different.

Here's the XL pinion. It's got a smaller diameter and the threads for the retainer nut are right were the bushing needs to be.



Here's the WL pinion. No threads, shorter and larger diameter.



I'm thinkin' maybe turn the threads off and press a sleeve over the end to make it the correct OD. The WL didn't run a retainer nut so I'm guessing it would work here too as long as the end of the gear is smooth enough to run against the cover bushing.

Anyone have any other ideas?

How about an earlier XL pinion shaft? No threads, but I can't say I know the difference in taper or length.

Here's a '57-76 pinion. Looks like they used a smaller case bearing. It's worth looking into though. Maybe the old case bearing will fit the newer case.... EDIT... Early models had cage bearing, not needle bearings.
