Radiator is 1 1/4", but engine 1", so I will be adding reducers between.

I was able to use 1" to 3/4" copper reducers from lowes on my yanmar.

I did take a half hour or so before milking to remove the top radiator mount.  I used a cutoff wheel to slice the centered bracket off at the base of the weld.  Bolted the cross bracket into place, got radiator pulled snug to the bottom rubber mounts, covered the radiator top with steel, then tack welded the center bracket into the correct spot.  Got it right this time.  Tomorrow sometime I'll unbolt the top mount so I can place it on the welding table to finish welding.

Bought a Stewart Warner mechanical water temp gauge off ebay this morning for the diesel HD.  NOS, and matches the OE amp gauge, and I also bought a matching SW oil pressure gauge for it a while back.  Since Bush Hog exclusively used Stewart Warner, I wanted all to match.  May go to the shop for a little while before heading out to check on Dad & do some errands in town.

I also ordered some bushings for my steering box, and they arrived today.  Most places wanted $7 to $12 each (need 2), then shipping.  I got 10 bushings DELIVERED for $19.75  It's a common size too, so I'll likely use the rest on other things.

Didn't get anywhere with the steering bushings.  I got the engine mount holes drilled & bolted, but they will have to come out later when I go to install a remote oil filter adapter.  That is where I got sidetracked.  I can't machine the adapter until I get my lathe drive belt installed.  I took the headstock apart so I could put on a serpentine belt...not a cut & clipped belt.  Man was that a frustrating job.  But I got the headstock back together, then had to drive the shaft out of the drive pulley to put the other end of over the pulleys on that end.  All is back together & working again.  I did manage to scar the bushing surface in the headstock to where it is just a little snug, but It will loosen up with a little time running.  Does perfectly fine at lower speeds, which is almost all I use anyway.

  Still good to have shop time, even if slightly frustrating.  The results were a lathe working again, and that sets me up so I can machine the remote oil filter adapter when I get the time.

I got the lathe bushings set right, and now it's working great.  So time to make my remote oil filter adapter to screw onto the the engine block where the oil filter normally screws on.  Started with a section of 3" aluminum round bar.  Turned it down to 2 7/8" wide, as that's all the room there is due to the flywheel backer plate.  Got the required machining done, and holes tapped for the fittings.  I pulled the rubber seal from the Perkins oil filter & machined the groove in the adapter for a tight fit, with the rubber protruding enough to make for a good tight seal.

 I am using a hydro remote oil filter mount off a 990 MTD to hold the oil filter.

I already had the hoses, fittings, and even a new engine oil filter in my stash of "stuff", so not a dime had to be spent, or even a trip to town.  The hoses are the perfect length to sit the remote filter inside the frame on the left, just behind the flywheel.  Easy access underneath for changing the filter out.

Looks good Daniel, that will make an oil change very easy and no frame cutting. Very nice looking adapter you machined, should do just fine. :thumbs:

Once I get time to lift the engine out of the frame, I can install the remote filter adapter, then the engine can be lowered & bolted in & stay there for good.  The engine won't have to be pulled when painting, as it will be the same red color as the rest of the tractor.  

   Gotta go start chores now.

Nice adapter Daniel. Inside threads are always fun. Did you use a tap or turn them?

Tapped them.  Never gotten the hang for cutting threads on my lathe.

I've done it a few times but only when I have no other choice. Takes me too long to set up the tool.  :mad2:
