Case material

Hey Y'all,
What are the main cases made of, I.e. the cases that hold the transmission gears? May need to fix them or buy a new one. Thanks, Tony

Thanks. At least I can try or have someone else fix my accident. Tony

The cases (an aluminium alloy) can be welded. The (some a magnesium ally) covers too but this is more tricky compared to the cases. Find an aluminium/TIG welder who's worth his salt, and I would torque both halves together during any welding so as to minimize warping, ditto (if possible) when machining any bores (like lineboring holes).

Now tell us: what did you stuff up?

Not on mine, the bolt goes all the way through and no threads in the subframe. Perhaps I eliminated them some years ago.


I had to check this, and yeah, threaded. A nut on it, ie a hole drilled-through on either side, is probably better in any case, as this way both tubing-sides on each side is clamped - contrary to only one now on the lhs, never mind the welding.
I'll see if I can find some plated ht bolts for you, should be easy here.

My mistake picture

So her is the part I may have welded up. The cam chain goes on the counter balancer next to this guard. I'm debating fixing it since the chain should be tight all the time??? What would y'all do? Buy another case, get it welded or leave it as is?

I did buy the throttle body boot off of a trx700xx to see if it will mate up to the xr650r head without too many mods. I bought the throttle body off of eBay. Now I just need to get the engine back together.
Thanks, Tony

Does anyone know if the Fluidyne rads have the mounts on the left side for the factory smog gear ( AKA fan mount )??

The smog stuff is on the right, but I am not familiar with the Fluidyne rads.

Also need help: who has the Jetting Tables (sizes, altitude etc) saved in some form (excel, picture or why) which were on Borynack's site (xr650r.com, now dysfunct) ??
I had it but lost it, and someone asked me for this this info.
If anyone has this pls pm me, I'll send you an email addy.


Wtt, you sure about that? Can't remember ever seeing anything like that, although Ohlins did supply shocks for the Pig.

Thouk, I'd have it welded up. Ask the welder to partially submerge it in water when he's welding, should help prevent warpage. Know that after welding you'll need to fashion the 'blob' into shape, a dremel would be handy to have for this.
If you want a 'perfect' shape make an imprint of clay or plaster-of-paris/gypsum beforehand, and use this to fit when you get busy shaping. Oh, of course remove the seal(s) close to it.

That sounds like fun when using a 220V arc welder. Any alum welder worth his salt will be able to do it without warpage. They just have to take their time. Every aluminum peice being welded/heated wants to warp. Its the nature of the beast.

STS,
you have not welded much I take it? Ali is welded by TIG, not arc - but even if so then such would work well, even if it would be a 380 or 520V machine. The submerging is to keep the heat localised, away from the bearing bores etc, which in this case (pun obvious) is easy too.


Babuja,
know Langewand, or the Doodsakker / Death Acre? It's the piece of carnivorous "beach" South of you, there were the dunes meet the sea, where one can only pass at low tide, springtide being best. I want to send my pig through that alley, and hopefully some others will join me.
IF this materializes then you ma bru will be high on the list to visit before we travel further, East to be precise, to the Indian Ocean. So, you may just get what you wish for, just closer to home
