d7 sprocket pressing

I checked my 17A service manual and "Cat Master Specs" and can not find the specs for the 17A.
I did find for the 47/48A dimension "A" being 0.440" to .0560"
Also the D6C 10K at 0.281" +/- 0.060"
I'd guess the 17A should be somewhere in between, important that there be overlap and sprocket splines flush with hub splines would not be acceptable.

If your Sprocket was running loose on the Hub this near always means 2 things, firstly that the assembly was not done correctly before, secondly the Hub and Sprocket are not fit to re-use, it might be worth trying the sprocket on another hub but there should be a margin after pressing up together between the 2 items, the standard found in the Service Manual is for good as New components, it can be a lot smaller depth without causing any trouble, but flush or past the splines is to far in that will cause trouble with the seals, the Dead Shaft also needs looking at to check the Key is in the 12 O'clock position and not loose in the taper. tctractors

OK, found the spec under the 977H (53A) loader.
Dimension "A" should be 0.220" to 0.300"

Thank you guys for the help. My splined shaft and possibly sprocket are toast. I'm glad I consulted with you all before I put this thing back together.
So the next question, does anyone close to central Indiana have a sprocket/ sprocket shaft that they are willing to part with? I am fine with going somewhere and removing said parts from a parts/junkyard machine, I have access to a sprocket puller.
The number on the sprocket is 4M4859 and the sprocket shaft is 6B5031.

P.S. I checked the dead axle and the key way is in the 12oclock position and the axle never appears to have worked loose.

Thanks,
Jim

About those part numbers?
I show a 4F6069 sprocket fitting the 6B5031 hub for the 17A plus a 4M4858 weld on rim.
Couldn't find an interchange for the 4M4859 sprocket you state.

Latest part numbers would be a 2M3504 hub, a 3S7092 sprocket assy. and a 3S7090 weld on rim.

Plug your part numbers in to a parts search on www.machinerytrader.com

I may have mistaken the 8 for a 9 on the 4m4858. I'll see what I can find with the numbers you gave me.

Thanks,
Jim

That Machinery Trader part number search is neat.
So is there a difference between old number 6b5031 and new number 2m3504 hubs for example? What all does the 2m number fit? A friend of mine had a hub off of a 977h that I looked at, but it didn't measure quite the same as my old one. The splines and threads looked the same, but it was about an inch shorter if I'm not mistaken?
Sorry for all the dumb questions, I'm new to this old cat equipment!
Thanks
Jim

The 2M3504 fits 17A, 7M, 3T, 4T and 6T. The 977H is a different number.
The 9S7092 fits D7, 977E, H
