1929 verses 1930 frame and 4 cyl engine

[1929luv]

Does any one know the differences between the 30 and 29 frames and Engines?  Do they use the same wood wheel and drums I have found the 28 drums are diff from 29 but have never compaired the 30 to 29 I have a 29 and have an opportunity to buy a 30 rolling chassis for parts and just wanted to  know if and how many differences thanks Craig

29 and early 30 used the same wheels and drums. I don't know of any diffrenc in the frame. Later 30s went to a 5 bolt hub you could get wood or wire spoke.

The Plymouth parts manual shows a different part number for the 30U frame.  I know the 30U boasted a welded frame.  The 28 & 29 frames were bolted together.  Whether the frames are interchangeable I couldn't tell you.  You might have to look at them.  There were two distinct styles.  Double Drop Straight Frame & The Rigid.X Double Drop Frame.  I believe the straight frame was used for the 28 & 29 I am not sure about the 30U.  The rigid X frame had an X cross member.   I believe the 28 & 29 has a straight cross member.   I don't know when the X frame was cut into production.

My 2 cents,  Chet...

Thanks Dan,

Everything was fabricated from standard stuff you can purchase at Lowes.  The only exception was the V Rubber, which came from an industrial floor-covering store.

Total cost for both was under $100.00 bucks.  Here again not original.., but practical.  I am still looking for the original metal running boards but these will work until I find them.

Welcome Aboard,  Chet...

I been meaning to tell you also that on the early 30 frame is straight cross members, riveted together. What I can tell from pictures looks just like a 29.

Doug,

You are probably correct.  I have not seen the 30U frame.  I was just reporting on what the parts manual stated.  The difference in part numbers may account for the welding only.  Another guess is that the X frame was probably employed with the new model transmission and bell housing in that it employed different rear mounts.  Possibly cut in toward the end of the 30U run but definitely for the 31.

Thanks Doug,  Chet...

My 30U has the stright cross members, but they aren't welded. They are rivited in place.

I thought mine was a later model as it has fuel pump, water pump and oval rear widow, but the production record show it built between May 25 and June 15 of 1930. They build 30U until June of 1931 so may have had welded or x frmes sometime later.

Just some info.

I'm thinking that the hot rivet was considered a welded frame.  Just my thoughts I have nothing to support that view.
