This is the extra thick washer that goes between the brake and clutch pedal on the pivot bolt. I am missing mine. I posted a request in the For Sale section in case someone had one laying around but maybe someone can measure theirs and I can kludge one together.

Part AAA4133

Nobody stateside seems to carry it.

I ended up stacking some washers to approximate the appropriate thickness. After two years, they seem to be still holding up fine.



Do you know why chicken coops have two doors? Because if they had four, they'd be chicken sedans!

Sounds like a plan!

I did the washer stack also.. You might find something at a hardware store in the little spacer box.

You need a lathe. Everyone needs a lathe.
Shall I tell your wife?

Rich,

The OEM pedal spacer measures:

1.00" outside diameter

.253 thickness of washer

.382" inside diameter

If you want, I can provide a picture of the entire assembly that takes a special Rubery Owens shoulder bolt.

Don,

Thanks for posting the measurements and please tell Andrew I have a lathe (bought it for my wife for her anniversary present).

Could you post the pic of the assembly?

Thanks,

John

John and Rich,

Here is a picture of the assembly. Three things to keep in mind when you are restoring/building the pedal assembly:

* Restore the running clearance between the M/C push-rod hole on the respective pedal and clevis pin. Note the clevis pin is .312 diameter
* Fit the bushing to the pedals so that the running clearance between the assembly spacer OD and ID of the bushing does not exceed .003" per side with a goal of .0015" per side.
* Make sure that the stack up of the assembly is such that the three spacers are clamped from rotation once the thru bolt is tightened so that each pedal if free to pivot between the ID of the bronze bushing and the OD of the clamped spacer.

With that said, it is a shame that so many other nicely restored MGA's lack the above detail during the restoration with the resultant are floppy pedals. My best recommendation if you do not have to tools or skill is to visit your local tool and die shop-not a shop that works on engines. A lot of these guys are car guys and often they will do this work for little or nothing since it is a break from their daily duties.

The OEM pedal spacer measures:

* 1.00" outside diameter
* .253 thickness of washer
* .382" inside diameter

The tubular spacers (X2) on either side measure:

* .752 long
* .375 ID
* .569 OD

The Rubert Owens bolt measures:

* 2.98 OAL
* 1" thread length
* 1.7" long unthreaded shank length
* .370 diameter of shank

I hope the above helps. Don
