B2620 not moving update and questions

[BWW]

Finally got around to messing with the little tractor. The ball coupling is defiantly stripped out! I got both roll pins out but does not appear there's enough splines to slide the coupling back to remove the shaft? So do i have to split the machine just to remove the shaft ? Where do i purchase the couplings since they are NLA? Thanks

Those couplers were used on 100 different models spanning decades. I would think theres plenty floating around.

You will need to split, sorry to say. I got some tall grass twisted around the shaft of my 2620 which tore up the shaft seals. Does the 2620 have a BH? Mine has the BH and the BH mounting brackets according to the WSM they need to come off, however I was able to split the tractor without taking them off. Had I known that the couplers were a weak spot, as mentioned, I would have replaced both them both even though they were ok.

Thanks for the info. Still trying to find the couplers!

@Mountainman might be a source for them.
Also send these guys a message and ask if they know if they will be getting more in, they are vendor members here and they supply great parts.

You can order parts for later-model tractors, such as the LX3310. Just don't try to mix parts from the early and latest designs of couplers.

Great info and makes perfect sense!! Is it just the inner and outer members that dont interchange or do you have to order all of the other bits as well?

They both use the same shaft & balls, but the latest version has added O-rings in the ball sockets.
The gaskets are the same, but the gasket supports are different.
I would not put used balls in the new couplers, plus I would use new gaskets and supports anyway.
There are no O-rings in the early couplers, so they would be a moot point.

The amount of work it takes to get the couplers off- why not use all new parts anyway?
