Got the farm work caught up till feeding time, so I went down to the shop to see if the HD-12 diesel would fire.  It's 23F, and I didn't have a trickle charger on the GT sized battery.  Gave the glow plugs about 30 seconds, then hit the key....instantly fired up!  Much better than most any of my other diesels actually.  The JD's have the glow plug timer, which is kind of lame, as they never stay on long enough.  Changed the JD 430 over to momentary switch, and need to do every one of them that way.  

  Drove the HD around a little bit, then moved one of my trailers to it's parking spot with it.  She's running sweet!  Was a short but nice therapy drive.

I think part of my starting problems before were due to having things temporarily wired instead of firm connections.  I had large clamps on the end of short cables that were bolted to the battery.  It takes a high dollar clamp to truly get the amperage through the connection, and these aren't high dollar clamps.  Now all is properly bolted in place & the starting issues are gone.

Sounds like a good therapy ride for you. That engine is a sweet little diesel to be able to start that easily.

Where's the video of you working her?

Nobody else was here to do video.  I'll do my best to get some video soon.  I'll put a hitch onto the sleeve lift & pull a load when I do.

Been working some on the HD-12D today.  Scott told me the right axle had a damaged keyway, so I did a decent repair. Not perfect by any means, but it should hold fine, as the tapered axle itself does a lot of the holding.  Used a brass bar machined to fit the key slot, then clamp it in & weld the axle up.  The weld will not stick to the brass & leaves the brass undamaged to use again.

Now the next pic shows I have installed a 5 lug hub to the axle, which the HD series used 6 lug hubs.  I am swapping to 5 lug due to I am going to 26x12x12 rear ags, and the only rims I have that will fit are 5 bolt rims.

I ordered the tires today.  They are Duro brand, which are decent tires that I have bought in the past.  Just $189.98 to my door for a pair.

I'll try to get the other hub swapped tomorrow.  While waiting for the tires, I'll have to put some 23x10.50x12's on it so I can move it out of the shop.

 

  The front 12" rims will be swapped to 8" rims with 18x8.50/8 turfs.  Using as much of what I already have as possible.

Nice repair. What offset did the 6 bolt wheels have from the rear? Might be the same as the FF's & Others!

I didn't check the offset measurements.  Those 6 lug wheel/tire assemblies are in behind some GT's and my knees don't wanna go back in there to see.  I'm pretty sure the rims are identical to what the FF uses.  They need to come out of the shed though, as they will go onto the Massey 2055 once I get the 6 bolt hubs installed that Brian (TD&H) sent me.

Nice repair job on the axle Daniel, I have square sticks of carbon different sizes for the sane thing on shafts.

I once made a similar repair to a piece of steel.  Had a piece break out of the side of a hole so a pin wouldn't stay in it.  I used a piece of aluminum round stock that matched the hole diameter, and about 1" longer, and welded over the top of the aluminum.  Took my time and didn't get it too hot so the aluminum melted... had to drive it out but it worked.

Nice to see you back at this Hog Daniel. Nice repair too.

What where those 5 bolt tapered hubs, that Brian sent you, off of

originally?

These aren't tapered axles on the "2055".  That tractor is a modified MF1650, so it has straight axles.  The straight axled 6 bolt hubs were off a Wheel Horse.  Which model I don't know.  But I do know the same taper is on both the MF 1655/1855 as on the JB & HD series Hogs.  My JB with the TJD twin engine has MF1655 hubs on it.  I just had to grind off the lip on the back side of the hubs for axle tube clearance.
