This is the list from partzilla. I don’t know that it’s correct or not. Also cross referenced the hub and is the same for the 92 rt180d. Spoke set# 401-25304-20-00. Shows available for $92 on sale. :S

Thanks Kev,
After much research I will use the spoke set you mentioned.
It is the same as what's used on 78DT175E.
Time to get my order together for rear wheel rebuild, more on this later as it comes together.

Hope they turn out! I would think so. Seems like finding OEM spokes requires a bit of sleuthing.

I scored another small victory today. If you go back to post #12, you will see that the rear axle was stuck in two places so was pretty much convinced that I wouldn't be able to salvage any of the spacers, but after looking at the prices of things I decided to do an experiment. I have alot of spare time & this project is not a priority to be finished any time soon. Long story short, I put the completely rusted axle ass'y in raw apple cider vinegar for a long bath/soak. I was able to remove most of the parts after cutting the end off a couple of weeks ago, but the spacer I need was still stuck. More soaking........:Coffee. So today while looking for some other parts to repair a mower deck I thought,"wonder how that's doing":?: I grabbed a couple of old bushings, a BFH, some WD & headed for the brick pile I use as a solid backer to hammer things out... To my amazement I got the thing to move 1st wack..:woohoo: so applied a little lube & continued to work back and forth till it came free...This will save me $22.00+shipping to use somewhere else..:woohoo: :woohoo: One other thing to mention, the junk parts, swing arm bushings & cut axle are now tools to use on something else.

So while I'm waiting on parts a deep clean was performed on the engine in preparation for a more in depth inspection of things like the bore which requires a top off look. Seals will all be replaced, etc. Anywho, what I've discovered so far. A repaired/broken left case. Your thoughts are considered a valuable tool as I decide what direction to go on this. Run it or replace it.



The flywheel puller I have used on all of my projects does not seem to want to work on this one. Seems a bit weird.
Thoughts,, Is the 77 IT175D diff from all others to follow? I'll be looking at bike spec's on this...

Cann't wait to see what lurks inside the clutch side as this is way out of adjustment.

Flywheel threads are the same. It's a super fine left hand thread (I forget that sometimes and try to turn the puller the wrong way) :Ugh

Sometimes a small wire brush will clean up the threads enough... worst case is someone used a cheap puller and when the threads failed on the puller, it damaged the threads in the flywheel... That's why I cringe when I see people buying the cheapest puller on ebay... The good Motion Pro like you have is only like $4 more.

Sometimes it takes a little file or dremel work to clean up the starting thread a little... I've even had to grind out the first thread or two in the flywheel... use a magnifying glass and patience. Make sure you thread the puller in as far as you can even though it might take some time/work... I think it was RT325 that posted a pic of his puller where he ground out a relief to make it sort of a "thread chaser"... I've never had to do that but looks like it would work.

Thanks Mark, yes it is the same according to the manual.
Correct me if I'm wrong, it's the only left hand thread I have to deal with to get at the crank seals too?
After looking closer at it, I have some rust to deal with in the threads.
Will try getting a wire brush in there with my dremal for starters.

Good news. Wire brush might be all you need.

And yes, only LH thread that I can think of on the whole bike is the puller recess in the flywheel...

If it was a DT with mirrors, the RH mirror would be LH thread too... but that's it.

You got me watching. The tension mounts.

Did you get those spokes yet?

Been side tracked, anywho I have started the motor tear down.
Appears we are on st'd bore: piston rough measurement is top @ 65.5mm bottom at skirts measures 65.6
No numbers stamped in top to indicate otherwise.

Bore rough measurement top 65.9 & bott. @ 66.0mm. Nice & clean....:)


Seems to be a lot of side play & angularity movement on con-rod, a .025" feeler fits snuggly in the gap. Need to look at specs.

wrist pin & bearing have blemishes.

Guess we'll send the top end off to Enduronut when I have a minute for evaluation and repairs.
I'm not sure on crank until I look at some specs, Who can service if it needs it?
EDIT: 14JUN am specs show AXIAL PLAY =.031/.079" (0.8/2.0mm) side clearance = .008/.028" (0.2/0.7mm)
thinking it needs to be serviced as side spec is very close to max ?
Will be hunting another set of engine cases with good bearing inserts. Thanks MarkT for your input & help on this.
Will be getting back to the wheels as this stuff is being planned & put in Que.
