250-2v aussie heade rockers lubrication

[dawnovsky]

HI,

I was wondering how were the rockers lubricated on stock 250-2v head.
on stock 200 rocker arms are cup type and have a lubrication hole. Oil was coming from the shaft to the rocker to push rock contact zone zone to cool it down and reduce wear.
I 've swap my stock 200 log head for a 250-2v recently. I have used the 250-2v rockers arm shaft (adjustable) and there is no hole for lubrication.
Are this assembly supposed to be lubricated by oiling type pushrods and lifters ??

thanks for the answer

my stock adjustable rockers had the same oil holes as the stock non-adjustable rockers. My pedastal mounted rollers need oil-through-pushrod lubrication and matching oil through lifters.which do you have again?

i have used an adjustable rockers arm from an australian 250-2v (ARD10E). No provision for lubrication of pushrod heads on the adjuster.

Isn't there a special rocker bolt that's necked down to let oil up to the shaft?

These is the rockers shaft installed. second picture from mustangmonthly, but similar to what i have.
It does look stock to me. oil is travelling up throught the cyl #6 pedestal to the shaft, then throught the saft from rear to front of the engine, lubricating rockers
As far as i rememeber, there is a hole on the top right of the rocker on the valve side design to spill oil that might flow down on the rocker/valve contact area. there might be a similar one on the pushrod side, but i dont remerber it. the adjuster screw don't have oil galerry on the ball side.

stock 200 rockers are cup non ajustable type and have an oil gallery to lubricates pushrod/rocker contact area.when doing the swap i choose to use the adjustable rockers coming with the head.

Same as my 1967 XR Falcon 200 engine...they came stock with them from 1960 to late 1967, even though they already had hydraulic lifters by then.




The rule is that if you use a Yella Terra roller rocker, or those that Classic Inlines sell, you have to use the right rocker tube (there was a small and large diameter version) and the correct kind of Small Block Ford Windsor 302 non roller hydraulic edge oriface lifter, the right length oil through push rods after trail fitting using an adjustable pushrod, and the right diameter oil through rocker ball.

1.I think the Aussie 250 reverses the stock US 200/250 rocker cup and push ball to another type.
2.The ball has to be the right diameter, measured with a micrometer, to suit the cups. Since pushrods varry so much, you have to be really sure the metal rod and the cups are compatable
3.Custom pushrods are best, but the ones you get can sometimes:-
4. get the wrongly matched rocker ball and cups, and grind the living daylights out of the rockers ball. Two instances of this on Ford Six, RickSmoll and another person.
5. You must check that the upper roller tip rubs the recommended part of the valve tip, not the middle third, but what Yella Terra recommends
6. The mid lift rocker angle has to be 90 degrees to the pushrod, or what Yella Terra recommend

Roller rockers, set up right, just require very carefull checking becasue the bits you get, might not be what you thought you ordered.

hi, thank you xtasy for your answer. still i m a bit confuse .
i assume i m using all stock part as the rocker shaft and rockers came came with the head. Those are not oil through ball neighter are the pushrod and lifters.
I have never read about oil through pushrod on the 250-2v or about the mechanical lifter type 144/170 who were using similar type of adjustable rockers.
am I wrong ?
What would you recommend according that everything is install now and i don't feel like remove head and gasket to change lifter of oiling type.
I have an extra non adjustable rockers shaft i decide not to use to ease valve adjustment.


regards

ps : my us mustang with stock 200 came with non adjustable rockers shaft
ps : do you have oiling type rocker ball ?? did you use oiling pushrod ?

on a stock adjustable rocker, there are holes on the rocker on both both sides, one squirts oil on the valve contact point, the other on the pushrod contact point.

only aftermarket setups AFAIK use oil through rods.

Any time roller rockers are used, you have to change to non standard oil through push rods and hydraulic lifters. Because of the need to elimate poor roller life, you must allow the rockers to be covered in oil due to the roller tip and shaft mounting. Oil allows valve spring life to improve. Stock, the valve springs need a good amount of oil. With roller rockers, everything needs proper extra coverage.

Stick with the stock 200 stuff, and when you get more info and the situation allows, move on with the roller rockers.

Make sure there is no spring bind or inteferance and use the stock Mustang stuff mean time. As long as the pushrods and assembled heights are similar, the standard two clicks on the rocker shaft at Fords recommended pre load should allow the hydraulic lifters to bleed out and eventually quieten down after an hours operation.

thanks for all your answers. It does help to understand. I ll stick to the stock confirguration for the moment.

so accordingwhat i ve red here and to the research i ve made over the internet there nothing to worry about using adjustable rockers with non oiling pushrod and lifters as this is the original setup.

now what about the oil outlet in #1 rocker arm shaft support ?
I ve got one on both mines, butaftermarket or recond model proposed by CI doesn 't.
Is it advisable ? as i understand it it allow oil excess to flow out of the shatf.
it sound like a good idea, but if none installed, it would create and extra oil pressure on the shaft and a more powerfull oil splash on rockers .

I use stock 1967 Ford 200 pushrods and 1963 200 adjustable rockers, no problems with them. They are not oil through.

Use whats there on the later XY/XA/XB rocker gear, it should be okay. I'm not sure what the differences are on that particular version; all my stuff is either 1963 log or 1972 log or 1981 log. Each rocker has a hole. The reson is that there is plenty of oil, and the rocker cover often needs a baffle becuase there is so much oil up there.

Just what you've got.
