Today's tool quiz - what are they and what do they do?

[Packard V8]

I've been around tools and automotive for fifty years and a machinist friend for forty. We can't say what these do. Can you?

There is a numbered set of six in a plastic box, plus one un-numbered with a different finish. They are from 7/8" to 1-1/8" in diameter and from 1-7/8" to 2-1/8" tall, but not in order. Some larger are shorter, some smaller diameter are taller. There are two opposing slots cut in one end.

Any and all ideas appreciated.

I give up :confused:

Just a wild guess but they kinda remind me of rear wheel drive transmission output shaft bushing drivers.If the other end from what is shown is capped they may be plugs to put in place when a driveshaft or fwd axle is removed from a tranny.

core drill bits!!:thumbup:

If all else fails i would stick them in the press and use them to push pins out with :lol_hitti

They look like the kind of tool that when you need one nothing else will do. I bet someone out there is working on something, scratching their head - "if I just had a _____"

That was my thought, sort of - I'd guess they are some kind of spacers/adapters for a larger specialty auto/machine tool.

We Used Air pumps to pump fluids at work and those look like the pump foot (filter screen fits inside). ours are held in place with 2 set screws.
At least they look just like them anyway.

Maybe they are drivers, and you put a piece of key stock across the slot.

[PistolWhip]

I think they're either core bits or spacers of some sort for a machining tool.

[bgott]

Show the other end.

They could be valve stem height gauges. This was a quick way to check to see if the valve stems were to long after a valve job. Simply dress the tips of the valves in the valve grinder to get the valves to the proper height. Could be, maybe! :confused:

[dledinger]

I wouldn't rule out gauges of some sort.....but what would the slots be for in regards to measuring valves?

[mrb]

I dont think those do anything that cant be accomplished with a big enough hammer :D

[Stephenw]

My guess...

They look like the nose of a torque converter. The nose of the torque converter drives the transmission oil pump. Perhaps those are made to turn transmission pumps. There may be assorted sizes in the set to fit different makes and models of transmissions?

I was thinking either a seal driver or guide. Is the bottom side open or capped, any wear marks, hammer marks, or residual stuff from use?

C'mon guys, I told my machinist friend we'd get the answer from this group within an hour. It's going on the third day and nothing even close. I'm aware of my limitations, but I was banking on a million monkeys on a million typewriters would come up with what we have here. Don't give up. Ask the smartest guys you know!

thnx, jack vines

[Moose-LandTran]

So you don't know what they are either?

[volvo420coupe]

Ummmmmm....... More pictures. Until then I refuse to contact old mentors and professors.

Back to the valve stem issue; the slots are a go-no go gauge. The height of the valve stem had to be above the lowest point and no higher than the tallest point. If the valve stem was above the tallest point the valves would not close completely when the rocker arm was bolted down. They even made a tool to dress the valve stem shorter after the head was installed on the engine in case the machinest did not set the height correctly. Many of the rocker arms were not adjustable, just bolt them down and let the hydraulic lifter take up the slack. :headscrat

Hi, longstroke,

Your idea of a valve stem gauge is a good one, but why are there six units with only 1/4" variation in length? Also, if they are used before the spring is in place, why are there different diameters? I want to know what these are as much as anyone!
