2nd Gear, cone type

Post by nick rogers »

I'm after a 2nd gear with PN 22A90 for a very early box. This is cone synchro type. Would really like NOS as I have 1st and laygear NOS but would settle for very good used.

Nick I might have one that is in an early 104 box. I will have to look and see. Only hang up would be getting the darn nut off to remove the gears, and that i am in California. Shipping from the States to England is not cheap.

Thanks Brian, I have already stripped one box down for a second gear but found it to be too worn. So please examine it carefully before going to any trouble.

Hi Nick. Been out of town all weekend and just now back. I actually have the box here at the house and won't have to go dig for it. I am not very knowledgeable with gearboxes even though for some reason I have a bunch of the darn things. As I understand it the cone gears have the synchro ring pressed onto the gear? Or the notched surface that is usually found on the synchro ring is pressed on the gear and the first gear has the smooth surface? Anyhow, what will I be looking for to see if its worth taking apart? Do I need to measure the distance between the gears to make sure its not too worn?

Just let me know what to look for and I will.

Cheers,

Brian

Brian, a few good photos when you have it stripped should be enough for me. The type has a brass ring pressed onto the gear. You can see that it is yellow so you can check its correct. Then we need to look at the little teeth beside the helical ones to see if they are still sharp. Thanks for this, I look forward too seeing what you find.

Nick I will get you some pictures when I get a chance to break the box down. I purchased an Austin 850 built in February 1960 about a year ago because it came with a couple 997 engines and some gearboxes along with crates and crates of parts. The mini and all the parts had been sitting since the early 1970's. The 104 box which I will try and take apart to look at the second gear for you came from this Mini and was already out of the car. Hopefully it's not in too bad of condition however the inside of the transmission is pretty dirty from sitting. I took a picture of the first motion shaft that came out of the box so I could ask you what the condition of it is. It's obviously worn but is it considered really bad or not too bad or "wow! that's like new!" Like I previously stated I am not very knowledgeable about gearboxes and figured I could learn something here. Hope you don't mind.

Brian

Ted, That's my old mate Keith Redwood selling the bush. Thanks for the tip but it's really the gear I need.

Thanks Brian, Those small teeth between the helical gear teeth and the cone are supposed to be pointed. I'll try to show what good ones look like. As the synchro starts to fail, the gears crunch when engaging and the points get rounded off or chipped away completely. This only gets worse as the synchro wears. The state of the synchro itself can also be assessed by looking at how smooth or sharp the grooves are. This is true for baulk ring synchros as well.
