Oil Dipper Orientation

[Crumpite]

We really need to get all of this info in one place where a newcomer like me can find it all !!!
I know there's been some effort on that line already...

So, OK - I need a 3" dipper since my Metro doesn't have an oil pump.
And given the reasonable price of the new dipper, I'll take an offset idler bolt too, if they're still available.

And where do you get the solid upper bearing set ?
(Daryl waves his pitiful supply of cash in the air...)

Thanks !

Daryl, send a personal message to JohnF for the bearings. he's listed in the members section.

guys, If I remember correctly you will also need the un-groved rod bearings from JohnF to make these work, but very worth the effort !

Not true....This design engine has been pounding dirt for a long time with no dipper or solid upper bearing. The dipper with either tupe bearing will enhance the oil supply to the rod bearing. Add an upper solid bearing and maybe more life.

Now if I had 40 or so 2" made! But alas I have six 3" dippers here. If you want one follow the instruction in the picture I posted. A possable offset Idler and 2" dipper may happen soon.

Can someone verify this please, its no use ordering the one without the other then.

XYZER, I've got a Dursley Lister and it does have a pump, I'll have to open to see what type of bearing is in it though, but I don't understand why that would be an issue, I would've thought that the grooved on would work better
I remember seeing hollow dippers on the Petter A&AP's, but not on any Lister's yet.

Seems like everyone is on the same thread at the same time posting! Got my answer while I posted, thanks!

The plain upper bearing shuts off the lube holes on the top of the rod and I dont think that combination would fly without either the hollow dipper or the centrifugal slinger with drilled crank. I cant see any harm though in using the hollow dipper together with the original upper. The plain upper though, like John sells, with more bearing area intact should last longer .

I had the experience once of absentmindedly installing a pair of main bearing shells without the oil hole to the supply it wiped the babbit in a few minutes. Got lucky and didnt ruin the crank. The replacement bearings had both shell drilled! They sure got wise to me quick!

I agree...........
Ideally I would drill the solid upper so the oil supply holes were still functional. That is just me....on a oil slinger engine with a solid upper bearing if the oil pump fails with no hollow dipper you die! With the oil supply holes on type you survive, add the dipper and it is like nothing happened!

So when I buy a new engine, (metro 6/1) it comes with a solid dipper, and what sort of upper bearing  bushing ? 

IS it something that has to be replaced immediately, or replace with a hollow dipper somewhere down the line?   

If the Metro does not have an oil pump, how does oil get to the upper part of the engine & cam, or is that all hand oil 2x daily? 

Does the spray from the solid factory dipper get any oil to the upper rod bearing? How can a hollow dipper get more oil to the upper rod ?

Lets see if I can help Mike......

So when I buy a new engine, (metro 6/1) it comes with a solid dipper, and what sort of upper bearing  bushing ?

It will come with oil groves and open lube holes on the upper bearing shells, and most likely a solid splash type dipper.

IS it something that has to be replaced immediately, or replace with a hollow dipper somewhere down the line?

At the minimum clean the crankcase and get rid of all signs of sand. Check the rod bearing for dirty oil test run, check rod clearance If it looks good you are ready to go. The hollow dipper is not a must have I believe most rod bearing failures are due to an Indian supplied dirty enviroment. The hollow dipper adds a little more oil to an already proven method on true Listers (some Listers had a hollow dipper).

If the Metro does not have an oil pump, how does oil get to the upper part of the engine & cam, or is that all hand oil 2x daily?

Splash....unless the 6/1 has a slinger (rare) to lube the rod bearing all 6/1's engines are splash even if it has a pump. The pump on the 6/1 without the slinger is only good for allowing you to filter the oil. They do supply oil to the TRB's but they really don't need it. The bushing type mains did!

Does the spray from the solid factory dipper get any oil to the upper rod bearing? How can a hollow dipper get more oil to the upper rod ?

The hollow dipper adds oil to the bottom of the bearing to enhance the oil supply from the top. Oil anywhere in the rod bearing is a good thing IMO!

Thanks Dave,
I thought that this was a "both or neither" situation. Nice to know I don't need the solid upper shell (in case of a failure & not having them on hand), but I still think I want them.
