[attachment=35062]933 pin.JPG[/attachment]Is that pin to hard to drill and tap install a round cap?
What normally holds the pin in position?
Jake: Page 8 of the Trackson HT4 Traxcavator Shovel Parts Catalog for serial numbers HT4 101 to HT4 2800 35C1 and up shows the following:
2 - Bushings (In EACH link assembly) Item IK6678 - the illustration from which this is referenced is titled " Bucket Control Linkage.
If the bushings and note Collar are worn, and under a repeated pivoting movement, the pin can walk out of the bore. Recommend you secure a Bunting Bushing Catalog - go to your local bearing supply house ~ Kaman bearing could help ~ and secure bronze bushing material to replace the worn bushing.
The book also shows 6- collars attached to the pins that secure the loader linkages to comprise the entire loader linkage assembly. If you need a scan of the parts illustration send me a PM with your address and will send one to you in the mail.
For repair, recommend you block the loader linkage with a stout piece of wood, remove any load from the bucket. Working safely use a bronze drift or better yet a piece or ironwood that is smaller than the hole the pin resides in ~ progress to tap out the pin.
It might be the case that both the pin and the bushings are worn ~hopefully only the bushing. Use a good digital micrometer and mic the pin and bushings and see if the mating surfaces are worn.
In close, always enjoyed your HT4 vids that you had posted. Keep up the good work!

Restore49, I did not think of that option. So you think it may be too hard to drill and tap. Now when I strike the edge with a punch its seems soft
What normally holds the pin in position?
When I first noticed the problem I thought maybe the pin had a slight overall taper and only installed one way. Then the collar was bolted to inserted end. So I assumed that maybe the pin or socket worn from a lack of greasing.
Om., I like your idea of welding it up to stop further wear. Dont think she will ever be a workhorse or showpiece haha.
RPeck, thanks for the info. You may have me confused with Jaker65 (jake). Ive enjoyed the same videos many a time haha. Sounds like a task of a repair and may take you up on the offer of some parts diagrams. ..Richard
