Combines 1994 R72 more

get some prices on the repairs. If you are a good mechanic, may be worth your time. I would look around some. Also, consider the good deal price into the whole thing.

Tack module must of failed around 400 hours and only available replacement has hourmeters. Had one running around hear like that also for years until I found module w_o hourmeters that I had repaired and switched with it. I use the newer module to switch with guys if they should have a problem. Newer module will work on all machines including electronic liquid R72, unsure about R62 with electonic Cummins. Then we can send there module in for repair and switch them back ASAP. That way they keep very close to original hours. Some guys have added boost pressure gauges and you may be able to wire in 300 RPM tack that R50 uses but I think you will become comfortable watching engine RPM that is continuously displayed on the R72. Sounds like you did your job looking this machine over and I'm sure it helped to have been around the miniature R72 (R50). The '94 is a very solid machine and I think your right on getting the wore idems taken care of rather than worrying a bunch about changes from year to year. Don't forget to be sure extended cylinder bars and feeder shocks are in on quote. Every year we get a couple two three machines from who knows where show up in our area without either. I feel sorry for the guys that had them. I guess it all boils down to how good of shape you want it in and if you want to justify trade $$$$$$. Good luck

G'Day Gerald I have a 94 R62 with 530 flex If it's the right price for you and you reckon you can do most of the repairs your self, I'd go for it!! Couple of thing I would look out for, and try to get the dealer to cough up for, would be the main machine drive shaft that runs from the clutch on the left hand side to the varispeed on the right hand side! get he dealers mechanics to replace the bearings on both the shaft and the clutches! and I think their may be a upgraded shaft and bearing kit for that!!! NDDan or Tbran might be know more on thatIJ I had one of my neighbours with a R52, machine out the bearing mount on the clutch and installed a double race bearing (slightly wider than standard bearing) in there so as to help with the loads that are normally on the single race bearing. You can speed up the fan by 5 to 10% (Slow the sieves back down) check the spinner spreader gears to make sure that they are not worn, also check the radiator spinner has got all it's cut off plates nice and close to the rotating spinner so as to make straw and chaff fall off better, get the radiator pressure washed and get them to do it over a few days! as this will soften up crud in the fins and it will come out better after a couple of washes! ( be Gentle!!!!!) don't be discouraged with thing's you might have to do to it! as it's really a lot easy than it looks to pull apart and fix or replace. good luck and have fun!!! Rolf PS: I have a 30 psi boost gauge in our 62 and have it mounted just above the pacer gauge and it makes it so much nicer to set the machine up and know how hard your running the engine!!!! plus you can tell the next driver to run at X boost and know it's been looked after!!!!

Just a few monthes ago there was big discusion on mainshaft and bearings. Still to this date we haven't pulled a mainshaft from R62-72. We have failed a couple left hand bearings and a few more right hand bearings but never had one spin on shaft. We learned many years ago to torque up nuts that hold drives on at predelivery and double check them after use when ever posible. If inner race of bearing is crimped tight to shaft it will not turn on shaft and cause damage if machine is stopped anywhere close to time of failure. The large nut on end of that shaft not only crimps bearing to shaft but it crimps the rest of drive to shaft also. The changes the company has made to that area not only included a slightly larger bearing but design of drive was fine tuned to help reduce importantance of torque (not to be misunderstood the importance of getting this stuff tight). I think drive only improved with time but original was just fine if torqued up properly. If things were ever allowed to run loose there could be erosion on surfaces which could prevent bearing from crimping up tight no matter what the torque so you got to pay attention when rebuilding. Rather than just change out these bearings I will listen to them closely. With extreme caution one can listen to them with scope with probe (very dangerous even for the experienced so don't try at home). Sometimes I think it better leaving a quite bearing alone rather than have someone damage a new one putting it on which fails shortly. I've never machined clutch pulley for a wider bearing but would like to see better life. The newer machines seem to be better with the wave washer next to outer race of one of the bearings. I had been tempted to mill out housing to double up ball bearings for I don't know if they would ever get noisy then. Just not enough trouble there to monkey around with things. Got to be careful not to make this nearly ten year old to good or dealer will need new price. Are you getting ready to harvest down there RolfIJ Best of luck and keep us posted with your refinements.

In addition to the accelerator roll bearings going at 600 hours, my '92 R52 had the left hand bearing spin on the main shaft when it had approx. 800 hours on it. Had to have it machined I guess it didn't get the type of pre-delivery inspection that you give to your machines Dan. Seems that more of this stuff needs to get fed back to AGCO so that the reliability of the machine doesn't totally depend on having a dealer that knows all of the tricks for each machine. This is similar to the hyper improvements that you guys do. From the day I got my R52 it always had a tendancy to overthresh and break up the cob too much in corn some of these hyper mods should come as standard equipment..sorry for the venting but it's little things like this that give Gleaners a bad name sometimes.

Nothing wrong with venting but hopefully it is in as constructive way as possible. The bolt that was loose enough to allow that left hand mainshaft bearing to turn on shaft is one of the retainers that we check torque on during predelivery. I don't think we have found one loose in maybe ten years but we still check. We also check PTO pulley nut, hydro pulley nut, corn varible nut, right mainshaft nut, RR accelerator roll pulley nut, seperator fan pulley nut, cylinder torque sensor bolt, and clean grain headshaft pulley nut. We have very rarely found any of these retainers loose from factory in recent years but still check them. Gleaner has maintained simplicity of these drives while making changes to try allow for a retainer that isn't quite up to torque specs. That is why I keep stessing tightness for I have seen to many times where a drive was removed and replaced but not brought back up to specs. If you want to check bolt on your C62 that was loose enough to allow shaft damage on your 52 then just remove brushholder and torque that bolt up to 350ftlbs. AGCO Gleaner has paid attention to this stuff over time and I think it is rather evident. They have adapted to failure areas as well as crop flow problems allthough not as fast or complete as we would like at times. We're not done pushing the company to get these machines to better handle the hybred crops were seeing today. I'll mention just a few so called hyper idems we got in just a few years: Feeder shocks, rock door hump, high wide wire rear half of thresher concave along with front also on corn soybean machine, high wide wire seperator grate, extended cylinder bars to discharge, and very large cleaning shoe. Don't think for a second that Gleaner has plans to stand still with their design for the flames are still burning. Your comments are much appreciated and this dealer will keep pushing for you but I will also stand up for company if they have corrected problem that is being complaned about. You see generally were talking about so many years of combine production (80 years for Gleaner) and there has been lots of ups and downs. Gleaner didn't allways have control of the ups and downs but I think they stand stronger now with more potential than ever before. Thanks for letting me vent this time. Take care.

Thanks Dan for the followup you've also given me a good list of shafts to check on the C62 over the winter months. Despite a bit of frustration once in a while we are still very loyal Allis_Gleaner folks. We go way back with these machines with my Dad having one of the first Allis All Crop 60's then 2 C2's and between my brother and I we have had 2 l's, 2 l2's, a R52 and now the C62. Having you guys available thru this forum is an incredible additional resource and is greatly appreciated.
