Front axle Trunnion

[henk]

Hello,

What is the correct way to secure the trunnion through the front axle?
The New Major is different from the Super Major. I can't put a clevis through the crossmember.





I now have put trough a secure clip on both sides

Hello Henk,

Originally a very large split pin with a washer is fitted on both ends.

Best regards

I have noticed that the trunnion hole in my front end is worn egg shaped. Can I ream and bush it or would an oversized pin be better? Thanks.

[John]

Got the same problem, and with the radius rod pin.

[Frans]

I reamed it and made some new bushes.

Thanks Emiel,

How do you think about the use of the clip I have used? Would it be save? I could put a split pin at the front and a clip on the back. This way I can remove the trunnion easily to grease is.

Kim and John,

Mine are worn to, and welded. They have not made a nice job of it. The front hole fits but the back one is still egg shaped.
The problem starts because you can not grease the trunnions. I have made a small hole through the radius rod en and put a grease nipple in it. I think it can’t be done at the front axle, because it would weaken the part and it could crack.
I know Pascal has had the same problem with the crossmember.
The only way to fix it good would be drilling out on a machine and put bushes in it. They could be pressed in or welded tight. Fixing the hole at the sump for the radius rod is a bigger problem. You could do it the same way, but that means a lot of work. You have to remove the sump.
The bush and trunnion through the front axle and radius rod are available.

Thanks for the info, henk. More work coming up!

Hello Henk,

According to the manuals, the system is not to be greased. I can understand that, grease takes dust and soil and make wear going faster.

Safety is not an problem imho, when the pin falls out, the tractor falls down on the axle. Won't be nice, but nothing serious can happen as long as the tractor is stabilised with the a frame.

The system Frans shows, is Super Major, where the fitting is tighter and a grease niple is standard equipment. The complete design is different on a super major.

Best regards

Frans,

Nice solution. Is the trunnion self made or from another tractor type?

Emiel,

As far as I can see, Frans his crossmember is the same as mine. The one from Pascal looks different and has a hole trough to secure the trunnion. He also has a trunnion with a grease nipple.



I have read somewhere on the board and found in the parts list, that there should be a sort of washer behind the radius rod connection to the sump. Mine fit's without it. That's a problem when you want to remove the radius rod without removing the front axle. Was it only done on later models?

[Frans]

Emiel,

The crossmember on the pics is from a Power so the same a Henk's

Henk,

yes its all self made.

and here some more Pics from my Super

Say Frans, Do you have your own machine tools? Or did you have them made? I have two South bend Lathes. A 13" x 6' bed, and a 16" X 12' bed. Also a 9 X 42 Brigeport with a J2 head and a Newall Digital read out. Seems like I always need to machine something while doing repairs on older equipment. Dandy Dave!

[Frans]

Yes, I do have a Lathe (emco 10) and a milling (Freesbank) machine (dont know the right word) and iff I need to do some big work I can always take it to the workshop at my work that one is a bit bigger.

I dont use them often but I am happy to have to make some axels and bolds
