What is it?

Picked it up yesterday. I have no idea.

The wrench appears to have been adapted by welding a socket on it that way you could use a breaker bar or ratchet to apply more torque. I assume the fastener was in a low clearance location so a regular socket would not work. I have no Idea why the plate has been attached to the spinner, some close up photos might help to identify its purpose.

Oh ****... I've SEEN something like this, both the plate with its weird little protrusions (to catch either the folds of the paper or the pins on something) and the way it's riveted/pinned to the speed wrench handle... It's like to remove... damn... I am thinking a filter (conical air filter, maybe a water filter or hydraulic water separator filter element wrench??)... if you'd asked me 20 years ago I might have remembered, because I'mm almost positive it was something to do with systems maintenance on a bridge or a building.

I know - no help - but damnit, I've SEEN this before. Damn, that's frustrating!

I'm guessing;
The wrench is a torque wrench extension.

The speeder is for is removing caps with pin holes. Similar to a pin spanner.

 

[frakas]

is the speeder for lapping in valves ?

is the speeder for lapping in valves ?

I'd concur, it looks like it would be intended for valve lapping on large truck, and medium size stationary, engines The valve heads were provided with a pair of shallow holes to be driven by such a tool. Alternatively, some valve makers provided a slot to be driven with a tool resembling a large screw driver.

I'd suspect that small wrench to be a 'special', for two specific uses, possibly on some variety of small engine.

I'll third that. Looks very similar to the lapping adaptors that came with old 1/2-inch drive socket sets. Those got pinned to a special socket that you could put on any handle, including a speeder.

Thanks, That make sense. Thinking back there were two "flathead" style valve spring compressors on a nearby shelf. The dollar was a little wrinkled. The small wrench was there to keep it flat. It does have a 7/16 socket very nicely welded to a goex 100 wrench. The square side faces out.It has a 1982 date code. It has an additional number of gtla1103 stamped into it. I assumed someone made it for a special purpose. Maybe not?

Forgive the naïve question (only on second cup of coffee)... so the adapter was used to thread in a valve seat... ? I'm trying to picture how the adapter would assist in lapping the valves themselves...

As Carla pointed out above, in an earlier time many valves had two pockets drilled in the top of the head. These pockets provided spots for the tabs of the tool to engage the valve to turn it while lapping it in.

This has nothing to do with installing or removing valve guides.

It is possible that the tool in question was used to turn something else, like a flush screw-in cap, but the same process is involved - pockets to provide a grip on the part and protrusions on the tool to engage those pockets.

Elidas,

It was going to bother me until I found it, and I finally did. I think the valve grinding attachment permanently attached to that speeder looks a lot like this SK jobbie...

I'm not saying that SK made it, only that it reminds me of the SK.

I used to have an old Husky set that had a valve grinding attachment that adjusted like this Indestro 642

Alternatively, some valve makers provided a slot to be driven with a tool resembling a large screw driver.

Or an alternative 1/2-inch drive attachment. Here's a Blackhawk T-11 (neither photo very good, sorry) of that type originally provided with several Q.D. wrench sets...

Thanks.. I reread Carla's post and now it makes sense. This morning I read it as the head (not the head of the valve) had the pockets/recesses, so that led me to assume it had to do with the seats (thread-in instead of press-in) and was trying to figure out how the youknowwhat that would assist with lapping the valves.
