Default Monarch 30-20 and 30-18

A couple years ago I bought a 30-20 Monarch off of Stak and yesterday I had a chance to get the remains of a 30-18. My hope is to find a Beaver engine or a Lauson tractor thats in tuff shape to sacrifice for an engine. The biggest changes that I found so far between the two is 30-20 had a 7" frame, steering wheel and the gas tank mounted the long way and the 30-18 had a 5" frame, steering levers and cross mounted tank.

You could always use it to make a reproduction of the Rumely crawler Rumely definitely used a Monarch undercarriage on that prototype crawler.

I had that thought as well and that was my plan actualy till I got to see it and found the dive train complete. Also now that I know its different then the one I have I have more motivation to put it back the way it was. I got a couple leads on engines that I hope work out and maybe I can talk someone into casting a few pcs for me and it will be back to original.

D'you know which Beaver/LeRoi you're looking for??
My old parts catalogs are all over the map on both Monarch and Lauson..
"C" 20-30---JB; 20-32 "C"--JC, JD (no yrs shown) (30 McCord)
"C" 24-29---JM (33 Perfect Circle)
"C" 20-30 1923-24---JB
"C" 20-30 1925-26 JC, JD (38 Victor)
"C" 20-32 1923-24---JA, JB
"C" 20-30 1925-26 JC, JMS (50 Fitzgld)
None I checked listed a 30-18.
Bvr/LeRoi JA/B/C and the JM are 4s; the JD and JMS are 6s.
The 30 McCord shows the JA and JB cast en bloc--one headgasket--and the JA, JB, JC, JD all cast in pairs--two head gaskets...it's no error as both gaskets are illus in both the McCord and the Vic.
The 38 Vic shows the JA/B/C/D all cast en bloc and the JB/C/D also cast in pairs (JA not in the 38 Vic)..
My Lauson listings aren't any better--Bvr/Lerois listed are JA,JA1,JAS and JS...JAS and JS are 6's per those catalogs.
Some of the confusion could be that a 4 and a 6 were offered for the same tractor models.
Thre were larger LeRoi RXs and RYs in the bigger Monarchs.
With sympathy, Bud

Bud the 30-18 in 1921 would have the 4.75" x 6" JB motor cast in pairs with open flywheel and my 30-20 has the JB with the solid block and open flywheel but I did some measuring and I cant see why the one pc block wont fit on the old style crankcase. Best I can tell is if you put the later block on the early crankcase you would only have a small gap in the middle of where it bolts down that wouldnt effect anything.

What does the 30-20 need to be a runner next year?
