The master kit on it's way, and while I don't know yet if I will need new steels or not here are few important questions I have:
Since the steels are considered “selective” and vary in thickness quite a bit:
1) What thickness steels are used at the factory at the time of assembly?
2) Can various thickness steels be use in the given assembly to achieve the proper clearance (for example, K1 x3 of 3mm and x1 of 3.5mm steels combo) or should the snap rings of the different thickness be consider for proper clearance and keeping ALL the steels at the same thickness if possible?
3) If (1) is not know, would measuring the thickness of the originals, the “tooth” portion (since it does not wear out in time) give me fairly accurate reading of what steels I need to order?
4) Some “ultimate” kits come with steels as well, and these kits have the following:
K1 5.0mm (x4)
K2 3.0mm (x4)
B3 2.8mm (x4)
Is this a good basic start for most 722.3? If not, what would you recommend if I do need the steels...?
5) If I did have to order steels separately (aftermarket), B3 part numbers seem to be good across the board:
Steel, 722.3 / 722.5 Reverse Clutch (B3) [36Tx2.80x147x177] (.110 ") 36 Teeth (5.787" ID) 1981-97
Part number 68130BA (factory reference 126-272-6826)
6) but, K1 and K2 part numbers seem to be “bleeding through” and are transposed at so many vendors, so if anyone could provide the accurate K1 and K2 part numbers for above, I would be regretful!
Here is an example missmatch:
Steel, 722.3 /722.5 Direct Clutch (K1) (6Tx5.00x104x144) (.197 ") 6 Teeth (4.094" ID) 1981-97
Part number 68126BD (factory reference 126-272-3326).
Steel, 722.3 /722.5 4th Clutch (K2) (6Tx3.00x88x134) (.118”) 6 Teeth (3.464”ID) 1981-97
Part number 68120BA (factory reference 126-272-3626)
My understanding from looking at JPAT catalog (UK manufacturer of transmission parts )
All K1 steels to have 68126
XX numbers, all K2 steels to have 68120
XX numbers... So, who is right? What numbers to use when ordering aftermarket steel in the US?
Transtar industries however, have it in reverse, K2 steels to have 68126XX all K1 steels to have 68120XX numbers...
WIT is the same as JPAT, uses 68126XX number for K1 steels, https://www.wittrans.com/parts?type=..._pump&part=126
and 68120XX for K2 steels
While Cobra transmission is allover the place online, 68126B should never be a B3 steel https://cobratransmission.com/index....keyword=68126b
Do you see my little frustration?
