Nearly fell out of the chair.....

Since the tracks (pins and bushings) are 110% worn, I am planning on turning them. But... also thought about new pins and bushings. Seems no after market types are avilable so I called good old JD. $2100 in parts plus installation.

I did order one set. I have a good friend with a large CNC lathe. I have a manual one. Heat treating is available........... We shall see. If material can be bought that is very close in size and doesn't require a ton of machining

Might be in for another shock

We'll see what happens, but I have pins and bushings on order, potential delivery time of October.

Okay, I now DON"T have pins and bushings on order. As if my PISSMEOFF quotient was not already high enough for the week, they have cancelled my order for pins and bushings. They have also cancelled all pending orders for all stocking warehouses in the US.

Well, I got one set from JD to take a look.

Looks like a bit out of my ability/equipment.

For those intested:

Pins: heat treated/hardened and ground to size. Approx 50-55 or so hardness. .004 or so over 1"

Bushings: heat treated/hardened and ground to size (outside only on grinding). Approz 60-65 hardness


Lavoy, question (again), What if only the pins are changed to new? It MIGHT be possible to heat treat and polish 1" 4140 steel to make the new pins. If used with old bushing, it would not require quite the close tolerance.
