I bought a couple of Gyrotech's (very cool) large frame fans, and I finally got around to getting my act together and rebuilding my driveshaft with this fan installed.

I bought a yoke from Northern Drivetrain that looked like this:


That was $35

These can be found here:
http://www.northerndrivetrain.com/product/SPI-10-3-33X.html

Then, I had a local machine shop cut it down and turn a step in it to accept the fan. (another $35) I asked for a "press-fit", and I got a VERY TIGHT fit. I froze the yoke in the freezer overnight, then heated the fan hub with a high-temp heat gun, and still had to drive it on with a brass drift.
I doubt it will go anywhere, but I'll put setscrews in anyway, since it is drilled and tapped for them.

Since I was swapping the yoke, I figured I might as well replace the u-joints (another $24 for both ends).

So, adding this to what I paid to get my driveshaft shortened originally, when I did the engine swap ($75), I now have a very cool, custom built, $169 driveline.



All ready to be re-installed in the 1886 when I get back up to Idaho.

Wow. That's a sweet set up. When I first started my onan install last year I dropped my OEM shaft to a reputable driveline specialist, to have it shortened 2 inchs- a Spicer dealer -and told me it could not be done. They said that style of tube was not availible anymore and it was allready to short to go in the lathe. When I asked what about the pto shafts that come off the tranfer cases on dump trucks ( I know there shorter than this) they were like oh yeah, be about $400.00.

I book marked that website so when I'm ready I'll look them up for parts.

I'm a grounds equipment mechanic for a large university so I have access to lots of junk. I got my shaft parts of an old Toro Groundsmaster broom front PTO.

How do you get a hold of Gyrotech?

Nice looking set up Steve. The 1886 will seem like a totally different tractor with cool tranny oil.

I just looked back at the math in my original post, and realized I forgot the cost of the fan ($115 with shipping), so I guess I now have $284 in my drive shaft.

Whoever it was that started that thread about how much a restored Bolens was worth, it would never sell for as much as it costs to restore it. I have over $2000 in the 1886 now, and it still needs new rear tires and a paint job, decals, etc.

Steve,
I am curious. Did you have your drive shaft redone before we discussed making 2 piece shafts?
Dave
Yes. At the time, it was much cheaper to just have mine shortened than to buy all new components and build a sliding shaft.

$2000 dont seem bad at all .. considering all you have done. :fing32:

Not that it matters .. but do you have a rough idea of the time you have in it ?

I can't wait to see it 100% complete .. paint .. decals and all .. I wish I had the needed desire and commitment to do what you, Deerlope, Ed and a few others here have done to your large frames..

I have gone so far to buy decals for a 1250 , HT-20 and a HT-23 .. they are still on the shelf :fing20:

Great job Steevo .. I really enjoy watching it come along :thanku: :thanku:for posting all the photos and details of the project

The only reason that these large frames wore out was that they were never maintained. All equipment is like that. Having a good preventive maintenence program and they will go forever. But so many times have have seen some little thing break that really does not impair the overall operation of the tractor. It is left to go by the wayside until it becomes a major problem. Then the machine is just parked out of sight and most often out of mind.

Your completely right. A "little thing" breaks and it turns into a bigger issue down the road.

Put me on the list for one fan when you run them again, or if you have any left send the invoivce for just one (1).

Really nice driveshaft! I will probably need to build one like that for a repower I am thinking of doing.

Steevo did you get dinged for a $30 border handling fee?

By the time you get around to use them you won't know where they are. The one on my 1455 is still good but loose on the PTO shaft. With a little work and a few dollars I can easily turn that into a nice large frame with front and rear remotes. 3PTH and FEL. But next comes the H-16.
