There used to be a thread by Steve Brotherton entitled Odometer Malfunction which I reference in the link above. The thread was from 01 and described the repair in detail. I can't locate the thread any longer. Maybe someone else can.

Ooops. Here it is:

So Steve Brotherton is the first (for now until someone else comes along to claim earlier) with the idea of knurling the shaft. I can honestly say I never saw his post from 2001 and came up the idea on my own in 2006, using wire cutters (dikes) as the knurling tool, after looking at Diesel Giant's tutorial and deciding it cannot possibly work.

Kinda makes you wonder why D G does not change their tutorial. Knurling is clearly the best way to do it. I have also found that removing the collar opposite the pot metal gear, you only need to slide out the shaft far enough (about 3/4") to knurl the shaft inside the area of the gear.

Well my bolt cutter is only qualified for tiny bolts, kind of a mini bolt cutter, the handles are about 14 niches, What ever works to notch that shaft, I helped a friend do it in his shop and we used side cutters, worked fine.

I am really disappointed with mine. I had it all apart last fall, had it working well, and then it quit. It turns about 25% (roughly) as I see it. So when the weather cools, I will go through it again. I think I just did not knurl the shaft enough.

the best tool to knurl the shaft with is vice grips. they perform a uniform knurl evenly across the entire shaft surface, not just a few nicks here and there.

I think I'm the one who discovered the shaft does not need to be removed, just pushed out a tad from the other side, and knurled...
I claim first dibs on that bit of the repair!

Stevo · #22 08-13-2012, 11:18 PM

Vice grips..Nah, the nicest knurl is preformed by the mini bolt cutters, maybe we need a "knurl off"

My odo knurled with cutters in 2006 is working fine still. I also pulled the shaft out just enough to get the cutters on it.

How can you do this when the end of the shaft must rotate in the bracket right next to the gear?????

Doktor Bert · #25 06-05-2013, 03:18 PM

My R107 unit has no pressed on retainer. The metal drive gear is pressed onto the shaft from one side and the other end of the shaft just hangs out. Prying off the metal drive gear will no doubt destroy it.

I can push the shaft out of the pot metal gear with my fingers with no resistance whatsoever....

The 'stars' that hold the number wheels in place ride on an .080" shaft. easy to duplicate a new one from welding rod...

I have asked the same question. This is NOT the way to do it in my opinion. Using any type of glue is not very easy to apply in the correct spot, knurling the shaft works the best.

Doktor Bert · #27 06-05-2013, 05:57 PM

Knurling is great, until you have to push the knurl through the wheel and into the bracket.

Green Loctite will hold it, but applying it is not easy....
