 Topic: 8070 FWA yoke loose on pinion shaft
Posted: 31 Jan 2024 at 4:40pm |

I know this has been discussed many times and I tried searching with no luck. I need to tackle this project before planting season.
I have read that welding additional length of female splines onto the existing splined yoke helps. Is it best to buy a new yoke ($800) and weld the old on for additional length, or have a new splined blank welded onto the existing yoke that is loose. Or get all new. Also, does anyone know if it is an industry standard spline or was it unique to the axles requiring custom machining. I want to do it right and don’t mind spending the money, but I’m also not trying to make it a competition to spend as much as I can either. Any advice is appreciated. Derek in Mo

How is the shaft splines? I had a loose one a long time ago and bought a new yolk. No problem since, took out all the slack.

Same here, I replaced the yolk 2 years ago on my 8050. It was very loose before but the new yolk went on very snug and is still tight. I did keep the old yolk just in case I ever need to weld a piece on the end but my guess is 98% of the wear was on the yolk.

Thanks for the replies everyone. I’ll get a new yoke and see how it fits.

Cut 3/4 of an inch off of the nose of the old yoke and weld it on the nose of the new one. That's how I did mine.
