Massey 230 front pto shaft removal?

[shaeff]

Can't look it up now, but try the guest sign in at AGCO Parts Books and look at the parts breakdown. It should show what you need to know, but getting it out, that I do not know.

Thanks to the OP for starting this thread. I tried to replace the fan belt on my MF 261 with the 236 loader a while back and discovered the pump shaft in the way. Not being able to figure out how to get the shaft off, I finally put everything back together and made an extra long adjustment arm to compensate for the stretch in the belt. I've purchased a link belt to try if the solid one fails before I get the shaft removal thing figured out. Maybe this thread will show me the way.

stuck, if you look at my pictures you can see the shaft attached to the pulley adapter (mine was welded in but yours should be a left hand thread). I believe you would still have to pull the axle forward a bit to change the belt as there is no room to move the adapter plate foreword enough to change the belt any way. My findings...lol

scheaf, I did look at the parts book but I didn't know if there was a "trick" to getting it out. I'm hoping it's just threaded in.

UPDATE! I talked to a tech at the nearest MF dealer and he "thought" the stay pin got driven down and out, turns out he was correct. Other than the big burr inside the axle pin I didn't see anything wrong with the old axle pin but it has a new one in there now. We put some red grease on the new pin, tapped it in a bit pushing the old pin out and just kept greasing it every inch or so, it went in fairly easy. ymmv
I would like to thank everyone for their support and input and I hope this thread can help someone in the future.
I still have to either order a new adapter and shaft or weld this one back together which may happen....lol over $200 for the two parts

Davedj1,
Thank you. I'll be able to refer back to this thread when I get around to changing the belt.

stuck, one thing to keep in mind, you can slide the axle assemble forward without it falling, there are long studs you can slide it forward on, this gives you about 2.5". Unbolt your adapter, first though and it should make changing the belt a breeze. Good luck.
Also, unbolting the adapter plate off the pulley won't won't make the pulley loose, it has a center bolt.

Thanks again Davedj1. It's about time something I did was a breeze.

In your photos l see another attempted weld "repair" on the crankshaft pulley , might be worth while looking into a replacement for that while you have the whole front end separated.

Check it out - it might be quite reliable, although now is the time to determine so. The best idea may be to weld the replacement shaft in place, otherwise find another drive hub. Certainly renew the fan belt.

I went through some of these hassles when I reconditioned my engine. I didn't know if the shaft was either keyed with a grubscrew, or LH threaded to the drive plate but the engine was coming off, so I just removed the axle assembly then unbolted the shaft from the front pulley. The pulley had two large pieces broken out of the front sheave - but the belt could run in only the front groove. I could have obtained a used pulley quite easily, but I decided to repair mine with a sheave I machined off a 6cyl Ford car engine - they were the same diameter. The shaft was quite Ok, the drive bushes were tired, but I couldn't get replacement bushes quickly so I pressed them out, turned them 180 degrees and refitted them using two sockets and my vice. I also renewed the link-belt with a real V-belt.

Here's how I repaired my broken pulley:

It looked like this .....


And was repaired like this .....


I had to heat the replacement ring to fit it to the machined diameter. The brazed joint was where it cracked while cooling. After that little adventure, I reduced the diameter difference, hence the three grooves in the front, and braze to ensure it stayed in place - and it has. :thumbsup:

Patrick, thank you for adding your pictures and progress. I am hoping this thread will help future people in need of some help tackling the unknown.
Post up a picture of your tractor if you don't mine. It looks like you are doing a complete makeover, I am not, just getting it functional. The pulley on mine was welded but the inside is nice and smooth, I will install a new belt while I have it apart. I also found I can and did order a new adapter on Ebay as well as the shaft so I am on the road to recovery!
Would you mind getting me a picture of the adjuster on the bottom side of the alternator? Thank you. This one is another cob-job

So brown santa has been busy delivering to my shop! The shaft came in in record time (two days from time of order) ordered it wed at dinner time and it was here
friday, it was an Ebay find. The adapter took about a week (also ebay), it came in today. The tractor is all back together except for a new suction line which I will pick up in the morning, hopefully I can get the tractor back to my BIL tomorrow. I put a new belt on it and got rid of the tensioner that he had cobbed on there! LOL I hope he never finds this thread...lol
Thanks again for all the advice and help.
