These are measuring up from the top of the frame cross member to the bottom of the pan that was on the tractor when I got it.  Not sure if it is the right one or not.

This one is looking between the pan and frame.

Sounds like fun! On that JD oil pan, what is the distance from where it mounts to the engine down to the frame mounts?

 

 

Checked JDparts and this appears to be the correct pan, at least according to the pictures of the replacement part # M47054 that I can find online.

Thanks! That tells me I would need a JD pan for an engine I have here.

Making my list of used parts needed for the 312 before it goes back together:

  • K301 blower shroud
  • Dash (might have a lead on this)
  • Steering wheel (might have a lead on this)
  • Hood (Need to make a trip to Lyall's place)
  • Narrow rims (to replace my crusty factory pieces)
  • Hour meter (might as well install one with the new engine)
  • Volt Meter (because I can  LOL)

Travis

what size of rims do you need?  Front or back?

I do have a steering wheel that has a less dish than my 212.

Narrow rears for the 23-8.50x12 tires I believe the measurement is 6"x12"- Like the back of my 120.

I picked this one up just over a year ago. Like the 120 was to the 140, the 312 is a Cheap version of the 300/316. Found t with a broken rod and now you see where this is going.

Carved some time out of the morning to work on the 312.  Some call it tinkering but I call it Easter sermon prep.  :smilewink:

 

Removed the drive shaft from the pump and my suspicions were confirmed - the hole in the input shaft has worn with time.  I am not sure if it will need replaced or not.  I will get pics of for reference in a bit.  Also played around with the hard hydro lines I have from a 316k I was going to use for the left front hydraulic ports and I think they are actually for the right side.  The other side might be somewhere but after the two moves I am not exactly sure where that it.  

I also worked on the engine a bit since the valve spring compressor arrived.  Pulled the valves and springs out of the new K301 and the old K301 block.  Grabbed the dremel and worked on the intake ports a bit beginning with the old block and using what I learned on the new one.  I was able to smooth out the rough edges on the castings but want to polish them smooth before I move over to the exhaust side.  I cleaned up and polished a 2.2 Turbo II Chrysler before sem but that was an aluminum head.  This cast iron is an entirely different beast.  Also worth noting that the NOS k301 destined for the 312 has hardened valve seats and the old k301 does not.  Watch for pics in a bit.

Pics of the pump input shaft and you can see the hole is worn so there is slop.  The yoke looks newer as does many parts of the driveshaft.
