Crankcase oil distribution pipe inspection (Listeroid DES 18/1)

(1/3) > >>

rp928:
Hello everyone and and thank you for accepting my membership request. I am new to this forum and to Lister engines in general. I have a DES 18/1 (Listeroid) I am assembling from a kit and noticed something odd with the oiling system. I (hopefully) uploaded some pics to help ask my question.

I removed the crankcase door to view the internals of the engine. I followed the oil distribution lines to understand how the lubrication system works.

The line on the left appears to dump oil directly onto a roller bearing.


The right side is similar but has what appears to have a flow restrictor of some sort. Notice that it points away from the roller bearing.


The center connecting pipe appears to be split in the middle.


I have not been able to find any pics of the lubrication system online so unfortunately I have no example to reference.

Does anyone know:
 
1) Should the left line have a flow restrictor?
2) Should the right line be pointing toward the bearing and should it have a flow restrictor?
3) Is it unusual for the center connecting pipe to look like that? (Could it be two pieces and what I see is a seem that should be there)

Any help you can provide would be appreciated!

Regards,
Rich

Hi Rich and welcome to the Forum and all the fun.
It doesn't appear to be right does it! Can you contact your supplier and ask him. I haven't seen one of these as yet but believe that they are not a bad engine. You would think that if a restrictor was required it would be on both sides and that both lines would be directed at the bearings to ensure lubrication and what appears to be a fracture or a split in the oil line isn't correct.

Hopefully someone can come along and help you but also have a look back on the home page there is a tittle just for Listeroids that also may be able to help you out quickly. Well done on the uploading of the pics.

Not sure where abouts you are in the world but here in Australia there is a company that specialises in selling Listeroid engines and that is the sort of place to go looking for specs and manuals.

Thanks Cobbadog for the reply. I took your advice and so far have read thru page 16 of the listeroid threads.

This is what I found:
https://listerengine.com/smf/index.php?topic=7319.0

The pic in that thread shows the left and right oil tubes configured the same way mine is. The right side is closer to the roller bearing and like mine is not directing oil toward it. I suppose spraying a spinning crankshaft could fling oil onto the bearing but it seems odd to do it that way. I will continue to search the listeroid thread. Thanks again!

Apparently the connecting rod struck the center distribution pipe during "quality control testing". I found a ding in the tube where it hit and caused the tube to split. When I tried to rotate the tube to inspect it, it literally fell out of the right side oil pipe. There was no resistance to turning so it would have fallen out or continued to be hit until it broke if I ran it as is.

cobbadog:
that is an odd way of lubricating a bearing, run a pressure line to it but don't allow it to spray onto the bearing. Glad you picked up on the split tube and that it can easily be fixed. What do the guys in the Listeroid section say about directing the RHS towards the bearing, I would unless there is another reason not to.
