Combines l3 fines and pods in clean grain can we HYPER an l3

[John_W]

I have heard an enclosed cylinder from St John welding will perk up this old dude.

 

[marshall]

I have the St Johns enclosed cylinder and concave. It was the best money I ever spent on the l3. 25% increase in capacity. I have never choked the enclosed cylinder down. Very clean sample.

What will this cylinder do and how is it betterIJ also what or how do we know when the concave is wore ourIJ Have you used one of theseIJ Is there others that are as good or betterIJ

 

[farmerfire]

Well that sounds good. what else did you look at before you bought the st johns cylinderIJ What did this do to your height and speed of the clylinderIJ

 

[tbran]

Yes, hard surfaced wide spaced bars will be a noticable improvment, level the cyl and check the concave channel bars. Add a 25Tooth sprocket to drive the thresher beater unless you have a belt drive. The kit to open the front 5 louvers of the sieve about 1_8 inch over the rest will allow, usually, a cleaner shample. The feeder beater should be shimmed BEHIND the sprocket, raised to its full height level on both sides and most important make sure the feed is even. Junk in - junky stuff in the bin - junk out.

We" hotted up" an l2 [ Can't call it "Hypered". That honor belongs to Hyper, tbran, NDBran and Co. ] in the late 70's. Small grains, ie. wheat etc. Flat section on the rear of the concave, below the beater was cut out and a cell-grate made from 1_8 x1" flat, running across the concave on 1" spacings, installed in place of the flat section. Filler bars were made to close off the cell-grate if it did not work. Did a couple hours of work. No problems. Installed filler bars, ie.returned to standard, and got an immediate {approx.} 15% drop in capacity. Filler bars were removed and never used again. The grate allowed a much larger proportion of the grain to be beaten out of the straw onto the raddle before being thrown back to the walkers.

What do you know about sunny brook concaves and cyliinder barsIJ

 

[farmerfire]

We are in corn and soybeans not small grains will tis work the sameIJ

 

[tbran]

I have heard nothing bad, all good. There are many good aftermarket specialty mfgs that improve over the oem design for certain applications. Make sure if you change the grate and bars you get one designed for your application. There are some grates which handle corn better, some wheat better. I am a fan of hardsurfaced wide spaced bars. The only thing I find from suppliers is that they do not hard surface the vertical surface leading to the top of the bar whic they do hard surface. After a few hundred hours the leading edge wears away leaving a 'tit' of hardsurface material in the leading edges and this 'spears' kernals of corn resulting in more fines. This can be eliminated by popping the top cover and using a small side grinder and removing the tits or reversing the bars. On wheat and soybeans it doesn't lead to damage that I have found. If one takes their bars to these jobbers such as Trimpe in Seymour Ind they will on request do this complete hard surface. I am sure others will as well.

I run the cylinder slower and opened up a little more than stock. I really don't have to do much adjusting on cylinder hieght. The cylinder runs quiet and smooth. It does not get out of balance like the stock setup after unloading. I would usually choke the cylinder a couple of times a day in soybeans. I have not choked it one time in 3 seasons with the enclosed cylinder. I did all the research I could on the internet and by phone. Give St Johns a call and talk to them.
