Older MC grain dryers 400, 600, 800 etc
I'm sure there are a bunch of these older dryers out and about... in our area they are getting pulled out and having the cobwebs brushed off and being put into use.
Perhaps a thread where owners could share tips and tricks that we have amassed over time could be beneficial to the community.
Even pictures of your set up could be useful on triggering ideas in new setups.
So here is my story.... we were sitting around feeling defeated by the weather.. days short day time temp low most of crops in the field still. A MC400 came up on kijiji and I made a deal and snapped it up... I think it's mid 1970's unit (no circuit boards) I am completely new to grain drying so in buying an older unit, I may have jumped in the deep end.
Here are my experiences.
I easily found owners manual to download and print online.
I needed to replace all belts (my wife will babysit it and I don't want an preventable problems) the owners manual actually lists all the actual belt sizes... this means i wad able to get all, even the wide 8 and 4 groove drive belts ftom Commercial Bearing (Motion Canada i believe) in Nisku the same day. The lady was very helpful in roundimg up what i needed from various warehouses. The belts fit perfectly
Directions for belt install and the important tensioning in the manual. I used a luggage scale and a welding rod bent in a triangle as a makeshift tension indicator.
The dryer is PTO driven I'm using a case 2090 with a 1000 to 540 adaptor so the tractor can run slower.
I replaced the igniter spark plug... could not find one in stock around town (Westlock) but found a BR8ES the same but just longer threads, so I installed a few washers to get it approximately the same depth, about 1/2" into pilot burner pipe. Also gapped to approximately 1/8"
It is best to start the PTO with a speed just high enough that the plenum pressure light come on.
I had problems at first with the pilot burner going out, and hard starting, and when I did get the main burner to ignite, it would go out after 2 to 3 min. Turns out the pilot orfice was partially plugged, it should be removed as there is a kind of copper tube inside with small holes to prevent clogging. I cleaned and slightly wallowed out the small holes on the copper tubing attached to the brass orfice and ever so slightly used a small drill bit to enlarge the pilot orfice BY HAND... I did not power drill it..
After cleaning the pilot orfice, the dryer pilot lit easily and quickly heated the thermocouple slowing the main burner to light and operate flawlessly.
I should mention that I blew out the main burner as there was a small accumulation of debris from rust and what not... I didn't remove it, just blew it out in place.
I just ran it successfully for the first time today... recycled the first bit of the grain that dosn't dry with this style of dryer, so tomorrow hopefully I can get it running in the automatic mode.
I will try to keep my findings posted as i go along....
What plenum temps do you guys run your continuous dryers at?
Keep calm and combine on....
