1959 955 26a96 will 955k tracks fit

I think the chains will be diferent ,But if you adapt the sprockets and maybe the rollers they should work .Check the number of links in the chains .I think a 955K will have more links .

I believe your 26A is equivalent to our 12A and they all came with oil clutch.

Track pitch on the 12A/26A is 6.75 in.
Track pitch on the 955H is 6.91 in.

Tracks can be upgraded to 6.91 in. if you change to matching sprocket pitch. Grouser mounting bolt size may not match.

Pretty good chance the tensioners will interchange.

Thanks for the info it might be worth a look a this 955k wreck then it is ex army and has a backhoe on it.
My machine has two different sprockets on the back so I better check both mine are standard.

OM do you know if that forward dipstick near the right pedal is the clutch oil and is 16 quarts correct . I saw a thread on here that was saying don't use engine oil in there and use instead TO4 ?

Thanks heaps for the info hopefully my manuals will arrive soon.

Yes on the dip stick and fill capacity.
Originally used SAE 30 same as engine oil
TDTO/TO-4 is the current modern application/designation.

If you have mix-n-match undercarriage, see if you can get the link numbers.

I don't know where you're located, but the trans oil will differ according to climate. Here in central Texas where it gets really hot, I have to run 85W-140 in my transmission on my 955 12A. The dipstick closest to the right brake pedal is flywheel clutch oil (TO4) and the one closer to the gear shifter is transmission compartment, which also supplies/adjusts the level of the bevel gear compartment. The transmission and the bevel gear compartment have two different drain plugs though.

Here's some scans from the operator's manual:

Thanks for the scans d9gdon appreciate it.
I am in Queensland Australia so it is usually pretty hot up this way as well so I'll go with the heavier oil for the transmission then.
