Model T Ford Forum: Forum 2012: What does the dipper dip ?
Top of pagePrevious messageNext messageBottom of page Link to this message  By Bud Holzschuh - Panama City, FL on Monday, November 26, 2012 - 10:00 am:

I am installing a set of dippers on the connecting rods of my 1915 T. It has the 3 dip inspection plate/crankcase.

Question is: on the #4 connecting rod, where does the dipper dip from? There is no dip in the pan on #4. So is the dipper worthless on #4 ?

Thanks in advance
schuh

On the three dip pans there is actually a small dip in the pan where the fourth one can dip some oil, but it will probably just pick it up from all the oil that is flying around back there.

The movements of oil inside a running engine is likely more like a hurricane or tornado than like an orderly scooping of one scoopful of oil per dip of the rod. In a stovebolt chxxy there were pipes directing oil towards the general direction of the scoop - in the Ford the main oiling of the rod bearings comes from the beveled parting line where the upper and lower bearing halves meet. A chxxvy dipper helps churning the oil into a fog so the air is dense with drops where the rods moves. I'd guess a smaller amount comes in through the little hole in the bottom of the scoop, most of the oil to the rod bearings may still come through the parting line as Ford designed them?

The #4 rod is close to the flywheel - the oil fog may be so thick there so the dip in the oil pan isn't as needed there as it is further forward. #1 is usually the one that starves for oil - when driving up long steep hills and when the flow in the oil pipe is restricted.

The early one piece pans had a dip for the rear rod in 1909, but somehow Ford didn't think it was a good idea and dropped it. Much later in 1924, the four dip pan was introduced, so there may be some benefit after all. Terry Horlick has made a mountain pan with increased capacity dips that holds more oil for uphill driving.

I think the best help for the engine is a high flow oil pipe tapping oil from the hogshead in line with the flywheel & distributing the oil to the front of the engine. Lots of oil flowing all the time from the front to the rear & no rod will starve, even if it hasn't got any dip close below.

Schuh,

I brazed an extra well for No4 in one of my pans however the transmission shaft broke in that engine due (I think) to the pan being out of line by 3/16". I suspect that the misalignment may have been caused by the heat of the brazing.

Bud, I like Gavin, braze in a dam behind #4 in my pan (also on the access plate behind #1,2,and 3... part of the "Horlick Oiling system". The important thing is to finish all your pan modification or repair work before having it straightened on a KW pan jig.

If you don't put a dam behind #4 on a 3 dip pan then the dipper on #4 rod is no ("expletive" deleted) use.

Here is how I did it on my 1927. On the '13 I just did the rear dam on the pan (the cover doesn't go back far enough to put it there)
