Anyone know the mystery torque spec on these three camshaft flange screws? The line is blank in the manual and on all sites that I can find that post it as well.

You do not want to know. Just nip em up, they'll be fine.  :smiley:
FWIW.. I've seen torque specs where I just said, "No. Not going to do that.." (shrug)

If you are really worried, give them a little blue loc-tite, before you "nip" them up as Chuck suggests.

Anyone have a couple oil pump shaft woodruff keys lying around? I lost then one I popped out of my old pump. I'd gladly pay a few bucks and for the stamps. MGCycle has a minimum order of $10 plus $9 shipping. I've spent a thousand dollars there in the past few months but need nothing else right now, lol.

Thanks either way and have an amazing holiday season!!

It may not help this time.  but Iíve found that when I drop and lose something on the floor, if I can lay my head on the floor so my eye can look straight across/along the surface plane of the floor that I can see & find things that I would have never found otherwise. Add a flashlight to point where my eye is looking and it adds shadows to help things be even more visible. 

Sometimes you get a dirty cheek, but itís worth it to find that one off washer or piece of unobtaniumÖ

Should I use any high temp silicone gasket on the rear main flange surface where it slides into the case, and in the gasket and bolts?

Thanks again!!

While waiting on a brand spanking new rear Main Iím resealing the rear end and the tranny. Before I ruin and have to order more parts, any tricks on getting this seal out?





And anyone know where there's a diagram, instructions, etc on reassembly of the rear drive? Don't want to miss anything.

For example I think this spring ring came out of the spot in the following pic and the third pic is with in in there. Fits but is that where it goes? I believe I have another larger one of these from somewhere else as well.







Shop manual is not much help.

To remove that seal, I insert a wide, flat blade screwdriver (not too far in so that it doesn't gouge the alloy casting) and twist. The spring came from that seal.

How far apart is your rear drive - stripped completely to a bare housing? Or?

Thanks again CharlieÖ doh! Yeah I noticed those in the seals but thought this was something else. Promise Iím a bright guy, just a few feet out of my depth. Be better once I get this and the bottom end of the motor done. Hereís where Iím atÖ it was all working well so probably shoulda left it but forum kept saying might as well check everything. Gonna get far enough into the tranny to replace the return spring and whichever seals I ruin long the way but thatís it.

If you're on Facebook, I have lots of assembly photos on my business page, including nearly step-by-step of the rear drive. Starts here: https://www.facebook.com/photo/?fbid=4525474664241296&set=a.4310288142426617

The small seal of the rear drive is a little harder to replace than the large one, but since you already have the 'drive apart, it would be best to replace it now.

If I'm understanding the pictures of where you found the spring, it's the swing arm drive shaft bearing area.

That spring, looks to me like the spring used on an oil seal. No oil seal where you found that.

There is a seal on the output shaft of the trans, but I'm pretty sure that spring is too big for that seal.

Hi all!!!

Sorry for lack of posts... Charlie has been assisting via email and is a super hero. Making progress. Transmission and rear drive are reassembled after checking, replacing seals, shift return spring, gaskets. All brake cables, etc changed out. Still waiting on a brand new Rear Main after not being satisfied with the used one I had. Hoping it'll be here within the next few weeks as I'm running out of other stuff to do, lol. Have everything for the motor prepped and ready of the day that puppy arrives.

I'll grease wheel and rear end bearings and replace seals today. I have the bottom frame rails, rear end and center stand cleaned up and gonna hit them with some semi gloss black later int he week. Main frame is pretty clean, and seemingly somewhat painted by previous owner...  so I'll just touch it up a bit. Might clean up and spray the underside of the seat too.

Thank you all so much for the time and support... I'll try to keep this more updated... especially once I get back on the motor.

I cannot wait to ride again!!

Ok so since I was read the riot act(with the best of intentions and probably saved me a lot of trouble), going to bite the bullet and get the cylinders replated my Millennium. Got a quote for $600 including sending the pistons and them checking the piston fitting afterward and ring spacing... so not bad.

Will post every step, screw up, bungle and win here for reference for those that come after.

Got the pan off to check for chrome. Doesn't look like much of anything but a few tiny bits. Anyone with better eyes please take a look... anything I should be worried about?

Working on valve covers an beyond now... so we'll see how the cyls look inside.

+1 Kudos to Charlie.  I have to imagine heís broken a lot of motorcycles in order to know so much.

I sent my v7 Sport cylinders and pistons off to Millenium a week or so ago.  They called with a price almost immediately.  About $570.00 to plate both.  Very reasonable considering Gilardonis are more if you can get them and the bike keeps its original jugs. I canít wait to get them back.

That really is a fair price. When I was looking at a T3 a few years ago all I was seeing for replacements was about a grand by the time I got them to my door. Also as you said, you get to keep the stock jugs.

Finally got a NOS rear main... and about to put the motor back together... until!

So I spoke with someone that had worked on my bike back bafiore I had it.. went thru three rear main seals. He told me to double check the crank for pitting where the seal rides.. and it has some. Spoke to the machine shop that "checked and polished it" and he claimed he was surprised his guy let it go like this and advised me to being it to a crankshaft specialist they send them to for grinding... if they need it. So that guy, who really seems to know... measures the ring bearing area as out of round... showed me. Also the timing side is out of spec. So both of those need to be taken one undersize, and now I need a front bearing and new rod bearings(anyone need a brand new standard set?). Regarding where the seal rides... three options. Install the seal just a 16th inward our outward so it rides elsewhere, or get a sleeve/bad for the crank and he'll install it. He also says he's not sure that the way it is actually would have hurt the seal.. it was probably one of the other issues causing the leak. Anyone know where I can get a band/sleeve for that part of the crank? Also... for what its worth, probably going to get a partial refund form the machine shop... owner seems decent and they had a good rep... maybe the tech looked at mine on a Friday afternoon, lol. But either way, so thankful I caught it now! They guy that had worked on my bike before said it was mean to be that we crossed paths that day... and I can't disagree.

Gotcha... yeah found SKF and Sturdy sleeves so far but none in the right size. Assumedly they come in fairly common sizes and the MG is not.

If anyone knows of a manufacturer that does... Mine is 52.91mm or 2.083 inches in diameter where the seal rides. That portion of the shaft is about 10mm wide.
