Dunedainranger 4 #1 Posted September 25, 2023 I was preparing to remove my drive belt on my '76 C120 Auto today, and after removing the clutch housing I looked inside and found a snap ring, multiple washers, and what appears to be some sort of lock washer. Thoughts on what I may have discovered? Share this post Link to post Share on other sites
wallfish 17,014 #2 Posted September 25, 2023 The washers are "races" that go with the trust bearing and the clip is what retains them on the shaft. Search the files / manual section for a parts diagram of the PTO so you know where they belong. I could probably find it and link it but it's kinda "Teach a man to fish" sorta thing. You'll need to find something else in the future so might as well get used to finding stuff. Top left of every page is the "Browse" It will drop down a menu for the different stuff. Click manuals and search away for your tractor and the associated IPL 2 Share this post Link to post Share on other sites
Dunedainranger 4 #3 Posted September 25, 2023 I appreciate the feedback. I have the manuals and associated IPL for my machine and implements. I just didn't find that component initially, so I asked for help. 1 Share this post Link to post Share on other sites

Ed Kennell 38,227 #5 Posted September 25, 2023 Search the manuals section for the IPL parts list for your tractor. .file:///C:/Users/ED/Downloads/Tractor%201973%208,%2010,%2012,%2014hp%208-spd%20IPL%20%23A-5343.pdf Share this post Link to post Share on other sites
Lee1977 6,670 #6 Posted September 25, 2023 It will work just fine with out them. My 1977 C-120 had them there was also a spring soposed and a 3/8"screw in the end of the crank shaft. You don't need any of that, all it was good for was to ware out the PTO brake. Share this post Link to post Share on other sites

Just like the park brake on the hydro- if it was necessary, later models would not have omitted them. Keep it simple. Many of the "improvements" that came on these tractors were items removed, not added. Share this post Link to post Share on other sites
Dunedainranger 4 #8 Posted September 25, 2023 Thank you everyone for the replies. I am just a bit confused where this is intended to be installed. Regardless, if you don't believe it is necessary and have omitted it without issue, then I will likely do the same. 7 hours ago, kpinnc said: Agreed.

A parking brake was always standard, but the previous monstrosity that activated it was replaced with a simpler system. The older hydros originally had no brakes except for a parking brake, and it locked the gears from turning internally. Really bad idea to set a lock on a hydraulic powered transmission, and they typically broke or wore down considerably. The system to lock it was also overly complicated, and wore out. Makes at best alot of noise, and makes keeping the drive belt tension "interesting". Later tractors had a functioning brake that simply locked the external brake drum for parking, and this carried on until production ended on hydros. Belt tension was maintained with a simple spring and swingarm. Edited September 25, 2023 by kpinnc 1 Share this post Link to post Share on other sites
