Question the 440 without upper idlers

[samuelellis]

Hello I'm a newbie 440 owner,

Question received the 440 without upper idlers. No idea why they were removed and crawler ran without them. I have access to some upper idlers from a 350, are they the same? Appearance wise seem inter changable but I'm not sure height wise from mounting bracket if one is taller then the other as I do not have the original 440 idlers.

Thanks in advance for any advice.

Look at photos of a 440 with the idlers and see it they would hold the track close to the same level.

I have a set of 440 tracks and the chains are the same size as my 420 (pads 2 bolt vs 4 bolt however). I'm not sure if the gap where the idler runs would be the same on 350 chains.
