Drilling holes can definitely be a pain when the sizes are close together. I often use a product called “Trefolex the magic cutting compound “, always a big help for that sort of thing. Don’t think you’d be able to buy it in your country, I think it’s an Aussie made thing, looks like green tooth paste but it’s great for cutting threads etc. Regards from Down Under.
i did think of something else. Drilling out that hanger beam to a thru hole now means there is nothing to retain those 2 dowell pins from vibrating out since neither side now seems to be a press fit and the hole is not a counter bore like it may have been before. Might be a good idea to strategically ching some of that casting with a center punch to purposely create some metal burrs if there is any material proud of the pin on the hanger support bracket? The burrs would create a stop to keep the pin from falling out. A real small strategic tack weld would likely do it also. Loctite on the tractor side might work too, but I would hate to pull it back off to do that unless you get lucky and the pins can be pulled with a magnet? Then simply loctite them back in.
They are tight enough. I had to draw it on the tractor ove the dowels with the bolts. Probably because the holes aren't exactly true because of hand drilling.
I would set that tractor drawbar such that the the distance from the very rearmost tip of 540 shaft on the tractor to the center of the drawbar hitch pin hole on the tractor is 14 inches in length. My most common drawbar style implements that use 540 PTO, which are my Hesston sickle style mower conditioner (aka commonly called a haybine) and my New Holland square baler, both recommend this same 14" dimension for the tractor drawbar length setting. I believe this to be a common standard in order to reduce driveline chatter by keeping the implement u-joint geometries all within tolerances during turns. Feel free to reference your manuals to verify my memory is correct though.
You are braver than me. I would have to ratchet strap the cast piece to a tree, fence post, tractor wheel, farm implement, trailer tongue, or anything solid so it did not wanna spin on me. I could better control the drill torque that way. Having to deal with the drill wrap as swell as piece spinning would be too much for me.
So….. what’s happening on River Valley Farm these days? Missing your great video updates, hope you and your family are all well. Regards from Down Under.
