...If you look closely at the picture of the stack of bogies, you can see that unfortunately one of six bolt heads sheared off leaving the bolt in the aluminum cross shaft. Bummer, but really glad there weren't more. I'd like to get that out of there and save $18 on a replacement. Anyone ever try? I assume drilling it out and re-tapping wouldn't be too difficult?
Did notice the broken bolt. If you have an "easy-out" there's a chance you could get it out and save the threads. Take the aluminum shaft out of the bogie set and get it in the vise but protect it between the shaft and the vise with something as a buffer if you can, like thin piece of aluminum on each side. Keeps from knurling up the shaft from the vise jaws. Then drill a small enough hole into the bolt, and try to get as close to center as possible. Then heat it up with a torch (not too hot). Add some fluids to help with the removal and go lightly on the extraction. Might work.... might not. If that fails then you can drill to fit what you want to replace with and tap. As long as you have the hole centered in the shaft its going to be easy. here's a link to just a generic set, no idea of they are any good.

Hey John (blizzardGR), glad to help. When you are ready, I can fix you up with a pair of Tillotson's for that Blizzard!!! And it's a good thing that I don't live any closer, or there would be two of us giving your poor brother advice!

Thanks Olyman for the welcome back after after being away trying to get myself fixed up - and the picture help. I will give that a try this weekend!
Doolittle, you and those darn Tillotsons!! Lol!

Had some fun today playing with a bogie truck cross shaft. See the "Tip of the Day" forum. Maybe this can help someone else sometime.

The fun continues with the 72 Nordic work. Bogies can be a real pain in the arse but this time I'm enjoying it. Its probably because I'm not trying to make a trailer queen. No blasting and painting. I'm just Dooing necessary routine maintenance. Before I install the "new" track and front drivers, I wanted to freshen up some of the bogies. Four out of twelve were grinding and wobbly. These were all the original bearings, so no wonder they were shot. Before...... After! New bearing slathered in low temp grease More progress to come...

Oh I can agree to the pain with the bogies for sure. I just did a round for the tnt myself. Those new tires look pretty nice!

Hi Olyman, believe it or not, the tires are the originals. They doo look to be in great condition, and technically they are for their age. Some cracks do show up when the tires are flexed, but they should last well into the future. I haven't been able to doo much lately due to work and other life issues and hope to get back to this soon. I'm somewhat regretting not installing double sealed (2RS) bearings but these are what I had on hand. These bearings came off my original 67 Oly, so they may be over 50 years old. They roll smooth, so I'm gonna run them. I figure I will never wear them out for how few miles I put on this sled in a year, maybe 50 total? They are 100% better than what was on there for sure. For the axle bearings, I plan to use new stuff since its obviously more of a chore to replace them. I've heard of some folks using the 6205-2RS that are packed with low-temp grease. In this case the chaincase oil does not provide the lube for the front bearings. What are you guys doing?

I did the exact same thing with my tnt. Cleaned up each bogie tire with wd40 and a clean rag. Nothing else. They came out great (InMyOpinion). I tried to reuse bearings and was able to on some. Some others that seemed okay out of the wheel got pretty rough when all of the bolts went back in and got tightened up. Lucked out and had just enough new bearings on hand to save the day. And ya those ones I was able to re-use all said NTN on the metal surfaces, but Bombardier on the seal. They must have spent a lot of $ getting rights to many things back in the day.
In the front axle I'm trying to keep oil in the case with good seals to allow the case oil to get to each axle bearing. I always wondered about drilling and tapping into the top of the case for a grease zerk but never done it. If that were the case I'd try to put good 2RS bearings on each side of the axle. Likely still need the seal, and would put a finger smear of grease around inside before assembly to keep the rust away.

I use the 2RS for all the bogies, pop a seal for the drive axle so the chain case oil can doo its job. Don't know if it's best but it seems to make sense.

Very cool. I would love to have a metal lathe at home.
And My son's 340
Very nice 340! Looks like it could be original too??
Btw - great to see you on here again crusher!

Btw - great to see you on here again crusher! It is mostly original, about 1400 on the odometer, seat cover needs recover again.
Thanks Olyman good to see you and all the rest of the gang.

Instead of watching the news yesterday evening after work, I decided to unplug by continuing on with my 72 Nordic project. The main objective was to get the replacement track as far on as I could. I had three used tracks to choose from. Two Ski Doo tracks that were not in the greatest shape, and one that I believed had come off a Harley Davidson. This is the one I went with and was purchased from someone on this site probably around 2006 or 2007? For sitting up on a shelf rolled-up in a box all these years, I was amazed at the condition it was in. I was also surprised at the brand name as I had never heard of it. The brand is INNOV. Ever heard of it??
The best part of the replacement is, unlike old ski doo tracks that seem to have a notorious reputation for shrinking, this INNOV track was not shrunk!! I was able to get it all mounted fairly easily all by myself, without any tricks like heating it up to soften it, soaking with tranny fluid, breaking out the come-a-long, etc. It went right on with only a few minor swearing fits. I filled the chaincase/gearbox with tranny fluid and this morning had no leaks. First time for this in about 7 years!. I'm happy as a clam.
So anyone else familiar with this INNOV track? Did it come off of a Harley? If you remember selling this to me, all I can say is thanks!! Best US$70 I spent so long ago! I thought I had spent $100, but it had a note on it that said $70. Win-win!
