DETAILS ABOUT OUR THREE PIECE KIT LISTED ABOVE
Adapter plate kit to re-power the small frame IH tractors with Cummins 5.9 / 6-BT or 3.9 / 4BT engines.
This listing is for an adapter plate, a new 11" flywheel and front mounts to fit the 460, 504, 544, 656, 666 and 686 gear drive in gas or diesel.
IF YOU ARE PLANNING TO REPOWER WITH A 4B BE CERTAIN IT IS AN INTERNALLY BALANCED ENGINE,
WITHOUT A BALANCER THEY SHAKE AND VIBRATE AT AN UNCOMFORTABLE LEVEL AND ARE NOT RECCOMENDED
Our plate is a precision built piece that fits the profile of the bell housing properly and looks like an original part. You can be assured the alignment is correct,
They are built on a 2015 model CNC machine and designed to use the original dial pins on the bell housing side and the Cummins style on the engine side so that everything runs true. This kit is built with pride here in the US and is designed for appearance as well as strength. Will be a re-power that you can be proud of and that will pay for itself in fuel savingsand added value to the tractor. Makes a pretty good conversation piece as well!
THESE ADAPTER PLATES ARE BUILT TO WORK WITH FRAME RAILS THAT ATTACH TO THE SIDE OF THE BELL HOUSING, (SEE PICS)
IF YOURS MOUNT ON THE FRONT FACE OF THE BELL HOUSING LIKE A 460 OR 656 USUALLY DID, YOU WILL NEED TO FIND THE
LATER STYLE FRAME RAIL MENTIONED ABOVE. OR AT LEAST YOU WILL NEED TO BUY THE ENDS OFF OF THE LATER STYLE AND WELD THEM TO YOUR EXISTING RAILS. WE CAN SUPPLY THE ENDS THAT ARE NEEDED.
To ensure the right length is achieved, we often have the customer buy the rear section of the side mounted rails, then cut and weld them to the original rails. This of course requiressome accurate measuring and a good welder to make them look like an original rail. This frame rail issue is generally found only on the 460 and 656 tractors and a few 656's have the outside rails.You should be able to buy them at your local IH salvage yard for a reasonable price. Frame rails in general do not sell fast or often. $75 to $175 per side seems to be the market. We have them access to them if you can't find them and may be building them to the correct length for the 656's if time allows.
The plate is built of Aluminum alloy or steel (by special order), comes with a new 11 inch flywheel and front mounts, This flywheel is built so that you can run a starter from the diesel version of your tractor in most all applications named here. Our ring gear has 134 teeth and measures 13.560 outside diameter, this is a common size and tooth count even on some of the gas versions of the models mentioned here. This means your gas starter may fit and work, count teeth and measure your existing flywheel gear. This flywheel will allow you to use factory 11inch IH clutch parts including the throw out and pilot bearing etc.. These are common over the counter parts from your local dealer or at any number of aftermarket parts yards and clutch rebuilders. We sell the 11 inch clutch kit for a 686 except we like heavier springs in the PP and 6 pad discs with the bigger pads.for $295 plus core.charge.
ALL ORIGINAL ADJUSTMENTS AND CLUTCH CONTROLS ARE RETAINED. THIS MEANS OUR HIGH PERFORMANCE TA'S AND CLUTCHES AND STRAIGHT DRIVES
FOR THESE MODEL TRACTORS ARE USABLE AS WELL!!
This adapter kit (plate, mounts and the 11 inch wheel) fits ALL of the models as detailed and listed below.
Row crop and hi utility 460, 504, 606, 544, 664, 656, 666, 686 in Gear drive whether Gas or Diesel
We have had one utility version of the 656 done with a 6 cylinder and it went well for the guy, can see no major trouble with any of the utility's. Although oil pan clearance around the wishbone of the axle may require a front sump and clearance for length will be an issue with the four cylinder tractors depending on which engine you are installing.
WE ALSO SELL GOOD QUALITY NEW RADIATORS WITH THE LOWER RETURN OUTLET ON THE CORRECT (RIGHT) SIDE. THIS SAVES TIME AND MAKES SENSE AS IT ELIMINATES THE NEED FOR A HOME MADE CROSS TUBE AND ENSURES THAT YOUR ENGINE WILL STAY PROPERLY COOLED. THESE WILL BOLT IN THE SAME AS YOUR ORIGINAL RADIATOR ON MOST OF THE MODELS MENTIONED AND IN MOST CASES YOUR SHROUD WILL BE A DIRECT BOLT ON AS WELL, SPECIAL PRICE OF $500 WHEN BOUGHT WITH A KIT.
THE 666, 686 IN DIESEL ALREADY HAVE A RADIATOR THAT HAS A RIGHT SIDE OUTLET
SEE OUR OTHER LISTINGS AND OUR WEBSITE FOR INFO ABOUT MORE UPGRADES FOR IH TRACTORS
THE PLATE THAT IS IN THIS KIT WILL BOLT ONTO AN H, SH, 300, 350, 460 AND 606 , 664, AND POSSIBLY SOME OTHERS
THE FLYWHEEL WE HAVE WILL WORK IN SOME OF THOSE APPLICATION AS WELL BUT THE RING GEAR MAY BE AN ISSUE DEPENDING ON YOUR STARTER.
MAY REQUIRE DIFFERENT STARTER OR MAY REQUIRE A DIFFERENT RING GEAR INSTALLED ON THE FLYWHEEL. WE DO NOT HAVE ANY HISTORY TO DRAW ON FOR THE SMALLER
VERSIONS OF THESE TRACTORS, JUST KNOW THAT A 4BT WOULD BE A REAL IMPROVEMENT OVER THE ORIGINAL ENGINES. WE CAN DO THE WORK HERE BUT IT WILL EFFECT THE PRICE A BIT.
IF YOU USE THIS PLATE FOR A 5.9 INTO A H, SH, 300, 350, 460 OR A 606 ETC, YOU MAY NEED TO BUILD OR SOURCE FRAME RAILS FROM A 666 OR 686
TO ADDRESS CLEARANCE AT BELL HOUSING AND TO ADDRESS THE LENGTH ISSUES, AND THIS MAY BE TRUE TO USE THE 4BT IN SOME APPLICATIONS !!
WHETHER ITS THE COST OF REPAIRS, NEED FOR FUEL EFFICIENCY OR JUST PLAIN FOR FUN AND CONVENIENCE THAT HAS YOU LOOKING
HERE IS THE BEST BUILT ADAPTER KIT AND THE MOST VALUE WE THINK YOU WILL FIND ANYWHERE!!
PLEASE ADVISE US OF YOUR MODEL AND SERIAL NUMBER AND IF YOUR TRACTOR HAS FRAME RAILS MOUNT THAT GO TO
FRONT FACE OF BELL HOUSING INSTEAD OF BACK ALONG THE SIDE OF THE BELL
WE TRY TO KEEP THESE PARTS AVAILABLE FOR SHIPPING WITHIN 3 DAYS
