Could someone tell me the bolt pattern differences. Ive heard of 201's in vac's and 300 round nose. I've got a 350 utility. Does the 201 bolt in or are big modifications involved. My tractor has the g-164 now. I had a. 351 puller. Put orchard intake on and was pullin 55 hp. I'm a John Deere guy also but these triple range tractors are pretty sweet. Is a 300 round nose chassis the same or is it lighter.

We have a combine conversion in a 411b, It's some work to do it especially to a round nose 300. for that tractor you would need the torque tube from a tractor with a 2 bolt block mounted starter, a flywheel from a tractor with a 188 gas engine. as for front covers etc they all will work. The 201 will have a 3 bolt starter an one of the holes on the block will need a heli coil to be useable. The tin will need an extra inch and a half... on a round nose 300 that might take some extra body work, also if its a wide front you need to lengthen that to. I'm sure there's more I'm missing if you need more info you can email me if it's open or call me at 651 491 5411.

I should have told you that a 300 round nose has a smaller bell housing than a 500b, 600b or a 530 or 630. You could use the bell housing and torque tube from the 500b, 530 or 630 on the 300 round nose then install the 201 engine.

I went out and took pictures of my 500b with a 201 out of a 660 combine. Added a inch to side rails and hood. Made a hole in hood for exhaust. Used the three bolt starter. I used the 164 timing cover and it had the smaller impeller on the water pump. I should have used a 188 timing cover with the larger impeller because on a hot day it will run about 220 degrees and kick out some coolant. The radiator has had some cooling tubes blocked for repairs. A easy conversion. I have used this tractor for several years and it is a power house. Will pull my M&W 10 wheel high capacity rake in 4th direct but will heat like it is. Need to replace radiator. I have put a electric fan pusher on the front of radiator but didn't really help much. I hope this helps.

The 201 is 1 3/4 longer block than 159 and 164. If remember right 164 has 2 bolt starter while 159 and 201 has 3,
