I'll be working tonight but I'm sure my mind will be trying to visualize how to drill the caps to install these dippers tomorrow.
I saw some videos and have had some very good advice so far from many of you. Thank you
One question that keeps me wondering, however, is whether or not to drill the holes in the center of the rod Or if offsetting them would be worth the trouble for any kind of benefit.
When all else fails, read the directions! Mine are and all the ones I've seen are on center.
Suggestion; fit the dippers to the rod cap. May need a little fitting to the edges to fit down and tight.
I tried to post a picture of the directions but the file was too large. It does not mention offset holes.
Centered holes seem good enough to be unless someone has better advice.
Bear in mind you are putting Chevrolet parts on your Ford!!
(For those who don't know, these are Ch**t 216 and early 235 dippers--or at least replicas of them, hence the fitting needed)
Some swear by these, others swear at them. I have no real opinion either way! (disclaimer!)
Dippers seem logical to me here in hilly TN. I'm asjusting the rods and will also add a front oiler. The plan is to make this a wedding car and hopefully puts lots of billable hours on it.
I drill the holes off center so the oil has a continuous path from the dipper scoop into the bearing. I then carve a small reservoir (1/4" wide)in the Babbitt between the oil hole and the center of the bearing for allow additional oil to enter the bearing. If the bearings have X grooves in them the reservoir is cut to the grooves.
The sides of the dippers between the bolt holes need to trimmed slightly so the dippers can be reworked to mate against the rod cap to minimize oil leakage. Don't take too much off the sides or the dipper scoop can come loose.
Thank You, Art
I always re-bend the "ears" on the dippers to accentuate the "Z" shape. Otherwise it's difficult to get the nuts on them. They'll pull down into the cap without having to trim anything.
Mike Bender talks about rod dippers in this video (about 10:30 in):
As Mike says, you don't have to trim anything.
Bend the bolt hole ends, just enough to start the nuts, and tighten them, and they will pull the dipper into shape.
Oil the top of the dipper at the bolt hole so the nut doesn't mar the dipper as bad as if it were dry.
I drill mine off center towards the back remember there is write and wrong way on the dippers for install
Correct me if wrong by the dipper opening is on the cam side drill the cap on the drivers side
Thank You, Bob
