Default Oil feed and Webco Oil Fin

I had the motor down (71 650 T120R) to the barrels, got 'er all back together and she ran like a champ. I'm currently going through a few heat cycles and head re-torques to seat the new head gasket and other new goodies.

Not sure why I didn't check before, but today I was looking at how the oil gets from the Webco oil cooler to the oil feed tubes. On each tube there is a tiny hole and on each side of the Webco (inboard) there are holes for the oil discharge. Well, currently those holes don't match up. I never had the feed tubes out, so this is the way they have been for a while.

I'm using engineering logical sense here and am guessing that these holes need to line up in order for the oil from the oil fin to discharge into the rocker feed tubes. If so, I'm not sure how to rotate the tubes without pulling them, rotating, and re-seating.

Appreciate info to set me straight, tips and tricks, etc.

Thanks

They have a clearance between them so the oil surrounds the rocker shaft . You would never be able to make a feed tube with the holes lining since the rocker shaftes can spin while the end nuts are tightened so you would never know were the holes are .

I use those big brass capped nuts with my webco, and I sometimes change the tightness on them to change the flow. I used a clear tube to check if tis works and it does. Looser the nuts the moe oil gets into the head, tigter, less.

And like Trumpnut said, there has to be enough clearance to allow the rocker arms to rock.

Also 750cc trumps use a larger oil feed pipe fitting to Webco manifolds. Just in case someone fits one from a 650.

Can someone please tell me how to stop my webco from piss'n oil?? I have copper washers between the webco and the rockers as well as behind the feed tube nuts….not sure what else to do?

Loosen the rockers, tighten the webco than re-tighten the rockers? I want to use these cooler but don't want it leaking this badly….all else looks perfect on the T140 engine and the webco, no blockages…etc.

Searching and searching, found this…

""As it turns out, I didn't shave enough of the fins off the head when I originally fit the Webco. As a result it was about .020 short from seating flush. After I fixed that, (and annealed the copper gaskets, and put a little yamabond, and loosened the rocker boxes) and put it all back together, presto! no more oil leaks. At least from the top end.""

Will give that a shot.

Try annealing the washers or there is a like hollow type that crush (you can only use once) otherwise its sealant but use sparingly.

Thanks. Sorry for my ignorance, but use sealant where exactly? I imagine just on the threads? Does the webco need a copper washer against the rockers themselves or does the oil cooler just butt up against that bareback? I have new copper washers I can use so no problem there.

I would not use sealant. Use copper washers on the front and back of the oil feed

Ok, I did do this initially but it was still leaking, more than is acceptable anyway. So I will try the loosening of the rockers, install webco (with new copper washers), tighten webco, then re-tighten rockers. Hope that works. Thanks.

I use the little paper? insert crush style washer that MAP sells and smear a bit of Honda bond on those making sure none can get into the holes..another trick i"ve used with copper ones is rub the washers on some sand paper in a circular motion= scrathes around the washer..that helps em seat good and not leek..of course wash em off first..

and.. I punch a dot on the non feed end of the rocker shafts at 12 oclock with the oil holes up..this way when I torque the feed down I can make sure the shaft don"t turn on me..keeping it on top so the oil can run down the shafts..and I also own a Lion Head Rabbit..

the secret is,
to loosen up the rocker boxes on the head.
then tighten up the Webco oil block using it to square up the fitment seals to the loose rocker boxes.
Then you tighten the rocker boxes back down on to the head..

when using new copper washers straight from the packet anneal them before using, i've also used the thinnest wipe of loctite on the washer faces. be mindful that this stuff will bung up oil ways like silicone if it gets a chance.

Tony is smart.
I've also read to not put on the head steady until the head doesn't need torqued anymore. Opinions?

Tighten head steady bolt up to the frame last. Not to tight as you will be retorquing after your run in period

i'd tighten down the head steady fromthe off, then ease and re tighten after each cycle of torquing head/barrels.
If the head steady ain't tight then it aint a steady anything and may as well not be there.
