Needless to say after 29 years and 57k miles the brake pedal bushing (part no. 90386-20130-00) is long gone. It appears to have been made out of a plastic material.
Finding one is impossible online as they are no longer available.
Has anyone dealt with this part or found a way to eliminate the play in the brake pedal with a substitute?
Thanks in advance.
I realise it's a bit of a kop out but....... Maybe someone on here has a spare right side footrest plate they don't need?
Or have you thought about having a brass insert/bush made by a local engineer that you could fit? Take them your brake lever and plate and I'm sure they could make up an insert in short order.
Thank you Dean. Going to the machine shop was my last resort. Around here, unless you know someone, there are minimums, set-up fees, yada yada yada. It needs to be done because the pedal will rub the side cover if I don't press outward and down at the same time.

Reloader,
If you have a great hobby shop or craft store handy, you may be able to find brass tubing which just fits over the shifter shaft, and a larger tube that just fits into the frame hole. Cut a piece of each tube to the length of the bushing needed. Cut several "extra" pieces of the smaller tubing to the same lengths. Cut a slit down the side of these "extra" pieces to make them a "C" shape. Open out the "extra" pieces to fit into the space in between the outer tubing and inner tubing. You may need several pieces of the "extra" tubing to fill the gap. When you have the right number of parts, dis-assemble your brass "bushing." Coat the inside and outside of each "extra" piece with JB-Weld (or similar epoxy), then reassemble your bushing. Tap the "extras" into place with a small hammer. Wipe away any excess epoxy. When finished, and the epoxy has cured, you will have a brass bushing to replace the worn part. Grease the metal bushing generously during installation.
Alternately, you may be able to find a hard "plastic" block such as Delrin. Cut, file and drill the plastic to fit as needed, and replace the old bushing. Cut the outside diameter of the bushing just slightly too large, to make a "press-fit" of the bushing into the frame hole. The inside hole will be drilled round. The outside diameter can be somewhat faceted; there is no need for a perfectly round exterior on the bushing. No lathe needed.
Maybe get some thin brass shim stock, cut a strip of the desired bushing length, and roll it up until you have a tube of the desired OD/ID. Hit it with some solder if you want to stop it unravelling.

Cool.
I suppose I'm lucky having a pal with an engineering business who will do stuff like this for me for pennies, but we have half a dozen small engineering workshops in town and they'll all do this type of basic thing for just a few £'s (a couple of minutes on an old manual lathe). Plus, we've this place only 15 minutes away - I haven't checked it out yet, but am doing so next week - it could be fun !!!

Red,
That is pure genius with the brass tubing, but as it turns out I have some Delrin stock that can be used. Just didn't think about it because it was out of sight, and therefore, at my age, out of memory!!
Pict,
Another great idea using the shim material, might use that if the Delrin proves to be a problem.
Thanks to all.
A farm type store in my area has quite a selection of bronze bushes in fact there is another one like Harbour Freight in the US that has quite a selection as well
If I can get a good sample or drawing I can make some on a lathe I have access too.
You can bend the pedal out a little, but be careful so nothing brakes.I did that on the fj100 i had before after it had fallen over and the pedal made a hole in the clutch cover pouring oil out.
Had a look on the pic of you bike in the other post and it seems the pedal is bent it also looks to be sitting to high .I like to have the pedal lower because of a injury in leg but that also lessens the chance that it will punch a hole in clutchcover if bike fall over

You might find shim material not particularly suitable for that application. If you're really limited for options, you can use your drill press like a lathe. I use an engineers drill vice bolted to the press table as a solid point from which to rest/pivot the tools used to form the outside and secure the job in the chuck with an adjustable ream, the inside is just drilled.
I had a small lathe for decades that was used almost entirely for making bushes and cleaning up shafts but sold it a few years back. I've since made some bushes on the drill press
but the best advice is to take up the offer of anyone you know with a lathe. A hobby lathe owner will leap at the chance to show off his skills, a shop owner would make one so fast he's unlikely to have the heart to charge you and hope you return sometime with a job that he can.

The shop owner is now my pal who makes little things for me - and I've put other people his way with bigger better paying jobs.

I will have to take a close look at the side plate on my bike to see exactly what your dealing with. When I install a bushing to repair a worn bore I open the bore up a little. 2 reasons, 1- it makes the bore uniform and round 2 - i y allows for a little thicker material on the bushing so it doesn't wear through as fast. You might consider using bronze instead of brass, it has a better wear quality.
I have a small lath and would be happy to do this for you. It would be best if you sent me the side cover so I could do a proper repair. Again, let me look at my bike to see what I will be dealing with first.
He is in Nova Scotia, Paul. At least I presume, that is what Nova means.
Anyways, shipping the rear set over would cost an arm and a leg. Unfortunately, it would likely be cheaper for him to just pay the set up fee and have it made locally.

I didn't even look to see where he was... Thanks Robert.

Robert, got an extra side plate? Send it to Paul, he can make a bushing to send Reloader to press into his side plate, maybe even a couple extra to keep on your shelves in Oakdale.
My vote is for Delrin, never needs lube.
Possibly, I'll make sure all the year bushings are the same and try and find a good brake lever too.

Never thought about that. I live in Northern Virginia so I will change the location to avoid that confusion.
My bad. :dash2:
Ok, here is a new twist. I looked closely at the side plate and there is a bronze colored bushing in the hole with remnants of the plastic (probably nylon) bushing that is listed in the parts catalog.
So it appears as if the aluminum side plate is bushed (no part number so I assume it is considered as one with the side plate) and then the plastic part listed by Yamaha is the insulator/friction reducer.
The plastic bushing would have to be about .007" thick if my measurements are close.
Probably better to press out the original bronze colored bushing and make one delrin bushing to press into the side plate with an inner diameter of about .785" for the pedal shaft.
Just rambling here.

Paul,
Thank you for the offer.
Please check out my last post about the bushing that is pressed into the side plate.

No worries. It's a worldwide forum. Sometimes the acronyms don't translate. Shipping to Paul in Nevada wouldn't be too bad then. Likely 30-40$
Thank you Robert.
BTW, just placed my third order with RPM, great inventory and great prices on unobtainable parts.
Best,

Glad we can keep your FJ going strong. No mail today with veteran's day but I will get it out first thing tomorrow and you should have it in hand early next week.
