We have incorporated every improvement and modification that we know of, to build this unit to be the strongest possible for field use.
Many of these improvements were direct results and carry over's from the tractor pulling world. This along with a little ingenuity and some modern technology
 has allowed us to put together what we think is the strongest TA you can buy anywhere for field use.   There have been several company's that through the years and by
trial and testing have pretty much taken the factory units and turned them around from a barely capable of 120HP TA to something that will stand a tremendous amount of 
power and abuse. We have combined into this unit  the best of those various improvements. 
 This unit will fit any of the "large frame" IH tractors from the early 706 all the way up through the 1206, 1456, 1066, 1586 and 3688
These are a great upgrade for the 2+2 tractors such as the 3388, 3588, 3788, 6388, 6588, 6788 and many of the IH tractors with Front wheel drive attachments.

 This vastly improved unit features a Renold sprag, the widest (1.200 inch's) and strongest sprag clutch available (see comparison photo,s). The Renold
sprag is the main item that separates our TA's from the competition. It is the strongest built that will fit into the IH application at this time and is the single most
important part in the rebuilding process.  It is the reason we are able to sell TA's all over the nation and a few to other country's around the world,
We use the same sprag from the 8 disc pulling TA all the way down to our lowest priced unit and we rarely have a failure!!
 
This TA has 1 extra clutch disc on the direct drive side (4 total) to increase the load pulling capacity by almost 35%.
It also has an extra clutch disc on the lo side pac which increases hold back ability.
 The factory had two discs on the lo side to hold back the tractor from freewheeling when in the lo side or "TA" position.
 By installing a third we have effectively brought the hold back ability up by 50%.
THE LO SIDE CLUTCH PAC HAS NOTHING TO DO WITH THE ABILITY TO PULL A LOAD!!!
But it has everything to do with holding a load on a hill or keeping a tractor from running off down hill when the lever is pulled back into the lo side.

The unit is built with the large 13 spline input shaft (Factory used this in the 1566) and features a load carrying bearing just in front of the oil supply bushing and ring area.
This provides a tremendous improvement in life of the oil supply rings and oil supply bushing. This is important in that it keeps the pressure to the clutch pacs consistent for a longer life.

A billet steel input shaft with larger pilot bearing and longer splines in the clutch area is available for $200 additional. The longer splines are a good option
 if you plan to, or even think you may wish to upgrade your tractor to a double disc clutch n the future.  We have several tractors out there running double disc clutches in
 the field with fully functioning pto's and clutch controls.

THIS UNIT IS BUILT TO OPERATE WITH PRESSURES AROUND THE 310 PSI AREA.
THIS REQUIRES A NEW HYDRAULIC PUMP AND A GASKET, SEAL AND SPRING KIT  IN  THE MCV BODY.
 Factory settings range from 260 to 280 PSI depending on model and many tractors are operating at less pressure than that.
We recommend that  you check your pressure before you dismantle the tractor to give yourself a base line to compare to.

These units are sold with 5 yrs warranty on components against mechanical failure.

THE NEXT FEW PARAGRAPHS HAVE TO DO WITH OTHER IMPROVEMENTS YOU SHOULD USE TO FURTHER IMPROVE YOUR DRIVE LINE!!  

BUYERS ARE WELCOME TO  CONTACT US FOR  ADVICE AND INFO

There are a couple of other parts that need to be changed out in order to run this TA in your tractor. The IPTO shaft will need to be replaced with a customized but factory built 18 spline shaft  which has a modified gear to clear the front carrier bearing and the larger 13 spline TA shaft,  See three pics above of the ipto, we don't just cut the gear off to clear the bearing, we back cut it so the extra strength of the wider teeth on the 15 series ipto shaft is use able. Note the difference in width in the one photo. We need your tractor model and serial number to supply the correct tooth count (either 26 or 28) and they sell for $195. This also requires part number 67837N which is the cast nose cone / tube that supports the ipto bearing and seal and provides the slide for the throw out bearing carrier, to be changed out as well.This item costs $75. To prevent gear damage and premature oil seal failure in the IPTO shaft area we have available an extra Heavy Duty Ball bearing built here in the USA. Costs approx $99.00 We have found this to be a great bearing for any of the large frame IH tractors that spend hours on heavy power takeoff duty!!   We use these instead of the roller bearings that the factory supply's. In our opinion the roller bearings tend to allow oil seal leakage into the clutch area. These HD ball bearings can be used in any of the IPTO housings from 706 to a 3688. E/mail or call with questions

 YOU WILL ALSO NEED TO UPGRADE THE CLUTCH  TO FIT THE 13 SPLINE TA SHAFT AND THE PRESSURE PLATE TO FIT THE 18 SPLINES USED ON THE NEW IPTO SHAFT.
If you are running a 14" flywheel this will only cost a few more dollars than a direct replacement for what you are now operating with. These are factory built IH original equipment items.
 You will be buying a clutch kit for a 1566 or 1586. If you are running a 12 inch flywheel clutch and go with this TA setup you will need to buy a
 flywheel and upgrade to a 14 inch clutch kit.  We sell new flywheels for most of these applications for $495.
THIS  IS ALSO A GOOD WAY TO EXTEND THE LIFE OF THE SPLINES IN THE PRESSURE PLATE HUB THAT DRIVES THE IPTO!
WE  LIKE TO USE 8 LARGE PADS ON THE CLUTCH DISC AND 21 OR 30 SPRINGS IN THE PRESSURE PLATE
We do make this ta available with the stock dimension 11 spline input shaft by special order if you don't want to upgrade your clutch but want the benefits of this unit.

We stock and sell all the related parts to go along with this install into your tractor such as gasket kit, with seal and springs, MCV 12 GPM hydraulic pumps (NEW ONLY), @$465;
 upgraded clutches,  IPTO drives and rear engine seals and some custom gear ratios for speed transmissions.
