82 Mugen 360 build

Look at the 3rd gear shift fork and I bet you will see wear or excessive play . Also the mating gears related to 3 gear will need replaced .

I tore it down today and didn't see anything wrong with the gears and it shifted perfect on the bench again.

That is the absolute worst feeling when something isn't working and when you get it apart everything looks fine.

I did more investigating and I did find the left fork was gaulded up and the gear it slide into was also messed up. I was looking for a missing tooth on a gear. I hope this is the problem. I've got another left fork but I need the gear that the left fork goes in if anyone has one let me know.

Make sure you replace both gears that mesh together not just the one connected to the worn fork .

If the sliding gear only moves to one side with dogs/slots/holes engage into one freewheeling gear that means 2 gears to inspect closely, if the sliding gear goes both L and R you may have 3 total gears on one shaft that may be suspect (like yours). after you fix 3rd gear problem 23471-961-010 2nd c/s slider gear slides into 23451-961-010 3 c/s freewheeler and locks it to shaft get you 3rd gear. and now it jumps out of 1st gear c/s 23410-467-010 the other way under load. Shan keep looking close at dogs/slots/holes close. also the other end of shift fork (pin) goes into drum groove... recreate problem by slowly shifting and look for damage to shift drum groove at each of the 5 gear points. widened or damaged groove. damn... i tossed a couple fooler bottoms when i talked to you last. dont know if they were good tho..
Oh and ck each and every shim, washer, snap ring and interlocking device (two tabbed washers that slip together) to make sure they are there. In my years of fixin Jap trans the forks gears and drums can fail but the damn washers snap rings keep workin fine as long as they are in the right spots.
Goes without saying but.. these gears and 23441-961-010 3rd m/s as wells as ALL gears have be faced the correct way on shaft also.

Sir. You are simply amazing.

Do all mugen heads have that mounting hole over the intake side?

I'm wanting to get the 360 back on the to do list. It's been on the back burner for awhile since 3rd gear was out of it. If anyone has any 1st or 2nd gen gears laying around let me know. I've looked on ebay and all of them have these gears confused with 3rd gen r gears meaning they want major money for them.

I've got a 83-84 lower end, but I have no idea what the condition of the transmission is. I know its missing the counter shaft so hard telling what else isn't in there.

[stroberts22]

The gears that are messed up are on the counter shaft but thanks for looking. I got all the parts to finish it up on the way. Been working on cleaning everything up and ready to put it back together. Can't wait.

[stroberts22]

All the parts are in to finish the mugen. I got the transmission shifting good on the bench. I got to go to the honda shop tomorrow to get some hondabond and some gear oil. Then after that I'm going to put it together for good. I can't wait to hear again and actually get it to shift into 3rd gear. The gears I got look to be in good shape.

Excellent Shannon.....and per usual, I would like to see a video of this beast

Hopefully it all comes together for you! Happy New Year!

[stroberts22]

I finally got it put together. I had a hard time getting it to seal up. It wouldn't hold 6psi for 6 minutes and the leak was coming for the left side crank seal. the actual seal wasn't leaking it was the o ring that goes on the crank. I had another one and installed it this morning and it fixed it. It's held all morning and it's only lost .5 psi. I've took some pictures of it together again and some of the head that I had to clearence for the pipe. I hate that I had to do that.

[redsox]

that thing is AWESOME!!!

I put it in the bike this afternoon and got it running. It cranked on the 3rd kick. I putted it around and it went in every gear good. It amazing on how fast it revs.
