If anyone needs a random RD or some R5 parts, I have odds & ends for both. Some RD125 / RD350 / RD400C & '71 R5 parts. All reasonable, thought I'd offer stuff here first before putting anything online FS.

I have a bro that needs a useable crank/rod assembly for an RD250. I don't know if the 350 uses the same...

Yes they are the same.
That's why you see people putting RD350 top ends on RD250s, making "sleeper" bikes.

I know I have at least one or two bottom ends still in engine cases.
I have no idea how close to being "in spec" they might be.
With any old Crank that's sat an indeterminate time, the outer seals will need replaced; but labyrinth seal normally don't. If it was me, I'd find a trusted wrencher who really know his stuff to check the dimensions VERY carefully before even thinking about putting an old one in w/o a rebuild. I do have a Factory manual which gives the tolerances, but you better have some very precise measurement tools and ability to use 'em...but I'm sure you know that.

If he wants one, I can check into what, or how many I have, but chances are they probably need rebuilt.

Have any RD400 transmissions? Countershaft sprockets? Clutch baskets?
Interested only in 400 stuff. I have way too much 350 stuff.

Thanks

Yeah, it's a funny thing, I'm guessing rebuilding that crank w/new seals and bearings is probably gonna cost more than the bike is worth. And I have no idea whether the rods are good. And I honestly don't know anybody in his area.
But thanks for the info, i'll see what happens with it...

Unga, I'll have to check on the 400 stuff...I know there's a clutch basket stashed somewhere, but I'm not sure I have any 1A1 bottom end cases. I'll do some looking in the next couple of days.

Yo, go digging around in the parts bin yet?

Not a immediate need for me, mostly curious.

Have any spoked rear wheels with disk brakes for a RD?

Sorry it took so freakin' long for me to get back to you. I've been busting knuckles trying to fabricate a new fairing bracket. On my second try now....sigh.

Anyway to my surprise I found a complete RD400 bottom end with pistons still attached (no jugs or heads) stashed with some other cases. I thought they were all 350s. But it's clearly stamped 1A1-XXXXX. The clutch is still attached. I forgot to check for a countershaft sprocket, but they're still available from many sources.

Anyway, since like everyone else, I have more projects than time, $$$ or space, if you want the entire thing, let me know what you think is fair. With everything I have going right now, working on both RD350s, plus I'm overdue on oil changes for both the Ninja 250 & Z, it'll be a little while before I want to deal with taking apart something else. If you only want the clutch basket & tranny, and don't mind waiting awhile also please let me know.

Again, sorry for the delay. It always sucks that I don't have the $$$ to buy the winter project parts stuff I need 'til March (tax return). Then the last couple of rainy months before summer are spent trying to catch up with what I wished was done by about January...

Add the fact I'm likely way slower and less proficient than most of you here, well I don't let that bother me...stubborn as hell :)

I have several bottom ends, I found one case tonight in particular, when I was checking on 400 stuff for Unga Wunga; the prefix was 352, which I think is a RD250, but I have more at least a couple more that are 351; being an RD350 it would work too.

Nearly any used Crankshaft you buy will probably need some work, unless you watch a friend take it out of a bike that ran an hour before; and if that isn't the case, I don't have the precision measurement tools needed to ensure how close to being in spec any of them might be. I would consider these suitable for rebuilding only, having sat in my garage for many years.

Quick, I thought I was the only one that had the time but not the money...never seems to change.

And as for slow work, unless somebody's payin' I tend to take my own sweet time unless I know exactly what I'm doing, which is rare.

I'll ask my bro if he's ready to spend some jag on a crank rebuild, and I'll let you know.

Thanks
