Hi All -

 

I am hunting for a conrod for my 1928 Senior Six (2251).    The engine is mid re-build and we discovered that one of the rods has a crack in it.  Any leads would be appreciated.  The photo shows the measurements of the current conrod.  Thank you.

 

Regards

 

Mike

May be able to help with this. Do you have a number that is on the side of the rod.

Just wondering how you went with the rear main oil seal carrier? 

They are made with pot metal and just fall apart!

The main number on each of the conrods is   200 002

 

But each rod seems to have a second number which differs eg. 11-2M, 24-0M etc

 

Does this help?

Our experience is the same.  The lower half crumbled to bits when it came off the engine.  A mate kindly spent an evening gluing it back together to get a reasonable proximation of what it looked like.  A local machine shop used the result to machine a new seal from a solid block of aluminum.  The test fit showed it needed a little modifcation, but now it seems to seal properly.  FYI, we were more careful removing the top half and it too was copied.  Good luck with yours!

The 200002 is what I think is needed. Headed to my shop a little later today and will see if I have matching number rods. Let you know tonight.

Do you know if 1930 or 1931 rods interchange?

Life got in the way of best plans today and did not make it to the shop. Tomorrow for sure.

Keiser - not sure about the interchangeabilty. I have a late 20s 6 cyl that is dismantled and have no plans to rebuild so hope the numbers line up.

Just looked up my parts book and it appears that the rods are only for the 2249,2251 and 2252 engines  Hope that this information has been helpful

I am led to believe that the Senior Series engine was designed by Dodge Brothers and was manufactured by Continental  The Chiltons Interchangerbitity book would soon clarify the problem

Hi Ron.    Hope you are well.  Thank you for the advice.  FYI,  the cylinder head that you kindly sourced for me many years ago was the only part of the engine that was in good shape when we took it apart!   We are hoping the conrod is the last missing piece so we can re-assemble the engine and get back on the road.  Regards  Mike

Here is what Chilton says.

The valves and guides were only used on the Senior. The camshaft and crankshaft gears or sprockets were only used on the Senior. The 1927-29 valve springs were used only on that engine. The 1929-30 springs were used on 7 models, four of them Dodges: Victory, Standard, DA and Senior.

Senior Six -  None of what I have is the 200002, also checked to your measurements and no matches. Sorry.

My thanks to everyone who responded.  I have located a pair of conrods in New York State and I will collect them at Christmas.  They are a bit of an unknown, but hopefully they will be crack free.

 

I am always impressed by the passion and generosity of the members of this forum.  Thank you again to all who responded.    Below is the last picture of the before the engine let go.  We were leading our class at the time.  Best regards, Mike

OK, I'll ask. Where is that and what was the event? Nice car, BTW!

Shamrock Challenge, southern Ireland.   It is a great event.

The goal for next year is the Land's End - John O'Groats Rally (LeJog).

That would be fun. But the first page of web sites for LeJog was for cycling!

Try:   heroevents.eu

This year's event just concluded, but none of the vintage entries survived to the finish.
