Default 1975 dt175 flywheel puller

I went to pull the flywheel off this dt175 and the puller I have for the 70 models seems one size too big. I dont see one specific for this bike although I think it might be 27mm. The one that fits my ct1 is a motion pro but no size stamped on it but its too big.... Anybody know?????????????????????????????

thanks rick I think just about any off them at 27mm probably will work. The ct1 puller must be a 28mm.

The CT1 is the same as the DT175.

A trick. Grind the puller down to the start of the threads so it will go in deeper and get more threads.

Not that it helps here... just thought I'd mention the "cheap" pullers all over ebay are sometimes not a bargain.

Stripping threads is one danger... If you've ever had a flywheel really stuck you'll see another difference... the cheap pullers feel like you're tightening and the bolt turns but nothing happens.. like it's starting to strip or something? Switch to a good puller and *pow* it feels solid and the flywheel, gear, or sprocket comes right off the taper.

One of the BEST brands I've found for oddball sizes is Dennis Stubblefield. Great stuff. Could not get the sprocket off my Allstate 250 with a no-name puller... the Stubblefield worked like a charm.

As mentioned, Motion Pro is also a good one for the 27 x 1 LH most of these bikes use and can be had for a good price.

What the cheap ones are good for is welding to the flywheel if you ever comes across one where the internal threads are hopelessly stripped.

OK, Here is a hint for those that strip puller threads.

I never use the "twist" of the threads to do the work for the puller. That's what will strip the threads every time.

Insert the puller,
Tighten it down solid,
now, wrap it with a steel hammer (not mallet)

the shock will bust the taper seal much faster than brute force of the threads pulling.

I'm just the opposite. I use a quality puller with good threads, make sure it is engaged in the flywheel as far as possible, and let the puller do the work it was designed to do... I've never stripped threads doing it this way.

Why don't I rap the end? Crankshafts are pressed together and trued to very fine tolerances.. it doesn't take a whole lot of banging with a lead hammer to move things a few thousandths when truing up a rebuilt crank.

I'm concerned a good rap on the end could knock the crank out of alignment... not sure it would... I just prefer not to tempt fate.
