Good day!
We have recently acquired a 750 no-till drill (S/N 009393) & have just finished inspecting it for wear / issues.
Major items we noticed:
1/ Quadrant & lever spline wear - with the castle nut a bit more than hand tight we've measured up to 3/4" of up & down movement at the guage wheel bolt hole on certain openers. This is only the play in the splines & doesn't take into account the play that is in the spring loaded pins that adjust the gauge wheels / seeding depth. A visual inspection of the splines shows significant wear with the crest of some of the splines actually being sharp. Re-adjusting the bearing to specs seems like it would only be the most temporary of band-aids...... Looking at TM159219 there is no specification / tolerance for these components so I was curious what people use as a benchmark for replacement?
2/ Opener arm seed boot mounting holes worn - The center set of holes on almost all of the opener arms are quite elongated / egged-out(the seed boot themselves are relatively new & have little wear in their mounting holes). This allows for close to 1" of up and down movement of the seed boot. Seems a few of the after market companies make bushing kits to repair these but just wanted to get some feedback on their efficacy?
Any other suggestions or tips on what to look for on these drills would be greatly appreciated.
Thanks in advance!
