Primered the fel brackets last night and was able to get some IH white sprayed on today.

I picked up the driveshaft from the machinist today.   It's not totally complete yet.  I still have to determine how much driveshaft to cut off, have a hole drilled in the shaft to attach the yoke, and have a short shaft tig welded to the old driveshaft coupler.

 

Here are the parts laying in there proper sequence. 

20160420_161218.jpg 20160420_161241.jpg 20160420_161306.jpg 20160420_210316.jpg

This is the short shaft that still needs to be welded.  The second pulley drives the fel pump.

20160420_212551.jpg

I have about 1/3 in. between the rag joint edge and the steering gearbox.  There should be plenty of room once the hydraulic hoses are plumbed.

20160420_214700.jpg

I made 2 cuts to the length of the driveshaft.  The first was 3 in. so I could make a more accurate measurement for the final length.  The second cut was about 1 in. for a total of about 4 in..  This is a pic. of the second cut.

20160420_213503.jpg

I'm leaving .050 in. gap between the coupler and the pulley.  This will make it easier to pin the coupler onto the shaft once it is welded to the coupler

20160420_215610.jpg

It's going to be welded on the backside of the coupler.

20160420_221414.jpg

I used another bolt to mark the location to drill the remaining hole in the shaft.  I also used a silver sharpie to mark were the yoke ends and the driveshaft exits the yoke.  This will help the machinist locate and drill the hole.

20160420_215838.jpg

Here is what it looks like back out of the tractor.  I tried to align the yoke 90 degrees out of phase (correction: they need to be in-line not 90 degrees out of phase.  See post 262 for explanation) with driveshaft coupler to reduce vibrations.

20160420_221348.jpg 20160420_221401.jpg

 

 

We will see how it performs once I can figure out why the start isn't working.  I'm having the start tested tomorrow.

I looked at the pictures first and thought the driveshaft was out of phase and then read you did that on purpose , is that because the different type of yokes your using ?

How much clearance is there between the yoke and hydraulic lines at the pump? I had looked into replacing a rag joint with a u-joint. The yokes I found made it extremely tight there. I guess I need to search for smaller yokes, not just off the shelf stock at the hardware store.

Alc,

 

I looked into the phasing of a driveshaft after I made my post and I need to change what I'm going to do.  I need the yoke on the drive shaft to be in-line/parallel with the front driveshaft rag joint connection.  I'll have the machinist drill the hole 90 degrees from what I marked it. 

 

Here is a link to a very simple video that will help explain phasing and angle.

Shorty,

 

I have plenty of room between the yoke and hydraulic lines.  If you look at post #252 on pg 17 you'll see the part number for the yokes and u-joint.

If you get rid of the rag joint at the pump you still need something that will absorb the shock from the engine.  This is why I moved the rag joint to the engine.

That had been my thoughts too. I had broke the rear rag joint and the drive shaft bounced around tearing up everything it could touch until the front joint snapped. A quick ending to the fun that day. Right now it is sitting in the corner waiting.

I had the starter checked the other day and everything was working fine.  I looked as some of my disassembly pictures and I noticed that I had the starter wires on the wrong post.  I switched them around and this is what I got

The engine is running clean and smooth.  I had to tighten the valve spring cover because of a small oil leak.  It's still seeping a very small amount so we'll see if it's residual oil or if I have to take it apart to reseal the cover.  I also re-torqued the head bolt to 30 ft./lbs..  They turned about 180 degrees.  I hope to get the driveshaft back tomorrow so I can see how she will function.  I also started prepping the fel lift cylinders for paint.  I hope to have them painted and installed by Sunday.

Your engine sounds good Mark on the vid. Glad you got your gen/start wiring sorted out too. I can not express how much dedication you have done to you 149 and the FEL! We all have enjoyed your restoration thread for sure. Also thank you for your membership as a site supporter!

I just got done going for a ride on it.  It really moves when you put it in high!  I'll post some pictures in a bit.
