Hi Shane I now know why the leaver and dirt cover is missing from my 996. It came with a pair of pliers pushed in behind the circlip what you call a snap ring. I pull it out with vice grips and slide the pliers in from right hand side. They sit on the pto housing. Good vid M
Justt like to say I read in one of your past comments considering your a computer/programming nerd your doing very well fair play for you for having a go and sharing your experiences on video. Can I ask you changed the o ring then changed it again for a different one where did you get the one you settled for was it david brown parts or somewhere else. Keep em videos coming but are ill you didn't mention Barry lol 😆
Thanks a bunch Jon! I've had this one in the works for a bit and was delayed to get that new bigger oring delivered and put in. Initially when doing it, I was so focused on the snap ring going well that I didn't notice the proper spec'd oring was that loose on the shaft. I was editing the video together and noticed it. Glad I did. I don't want that part leaking again. I've been ordering o-rings from The O-Ring Store online. www.theoringstore.com/store/ I've got to order minimum quantities but in many cases I'm getting whole packs of sizes for cheaper than 'kits' and they're here in a couple of days. I'm also sure of the hardness and quality. Ordering stuff from the suppliers like David Brown Parts in England can take a couple of weeks to get shipped here. I'm keeping a spreadsheet with the description of the part, oring descriptions from parts catalog, and the oring dimensions in both metric/imperial units. Makes comparison and looking to get a 'bumped up' size relatively easy. I'm using an Oring Size Chart from Seal & Design's website for the AS568 standard: www.sealanddesign.com/technical/o-ring-sizes/ Most of the CaseIH parts catalog descriptions now contain the AS568 dash number for reference. Lol, I thought I'd had a Barry mention in there, but must've cut it! I cut out LARGE sections of rants, dead air, mistakes, my sons bickering with each other, and wife hollering that dinner's ready.
I've never seen a David Brown 990 so I have no clue what that handle does. I assume it is something on the 3 point hitch cylinder, but how does the handle do anything, it looks like it doesn't turn the shaft, in fact what does the shaft do? Does the handle pull the shaft out as it turns maybe?
Good feedback on that, I need to introduce what I'm doing and what it does better for viewers. This video is a continuation of a series I'm doing on refurbishing my old David Brown 990 tractor. It's English made from the late 1960's. Yes, this is the latch that's used to hold the lift arms up at their highest point to lock them in place for maintenance needs or whatever. The shaft just slides in and out of the bore and acts like a shelf that keeps the arms from dropping. The handle has sloped areas inside that 'cam' against the shaft/spring pulling it out. Thanks for watching and thanks for the feedback!

Thanks Barry! I'm still jealous about how yours went together the first time 🤣😁

Yeah, I can imagine a few of these have fell off during the years from lots of tractors! Not the best design in my opinion.
