DYT4000 Deck

One of the spindles broke 2 of the 3 mounting tabs.  Order 2 new ones.  Will keep the old good one for a spare.

Murray 18/46

The tractor would not start because of a non working starter.  The guys on M.O.W informed me that it would come off without pulling the flywheel.  It did.

The starter was in very good shape just dry and dirty. Starter gear looks good.

Fired the engine with carb cleaner and it sounded good.  Much better than the 18HP on the 14.5/42. Maybe it just has a better muffler?

Tomorrow I will take a look at the fuel system.  Maybe get it running.  Hope it does not need a motion belt too but I think that is the case.  Thinking about that I should take a look so I can get it ordered if need be.

Could not sleep so played from 4 to 6AM.   Could not find the electric impact so I pushed the tractor to the other shop and used air impact to tighten the flywheel nut.  Later I found the electric impact in the tool cabinet.  I don't normally store it there so..

Moved on to the carb.  This carb does not look like it is 18 years old.  Pulled the top which you can do with the base still on the tractor.  Some crud in the bow.  Needle valve seems gummy.  Cleaned the bowl with carb cleaner.

Given that it had carb problem I think I will take it all the way off and run it through the ultrasonic cleaner.






















Pulled the fuel pump.  One of the little springs is missing.  Time for a pump rebuild kit.

Sept 30

Adding the missing springs did not help either tractor.   So time to do a good carb clean.

JD 112 Gas Tank

Started on the gas tank.  Scrapped the JB Weld off and found a puncture rather than rust through.

Started reverse electrolysis,

That worked well.  Also soldered the tank with lead/tin solder.

Now it needs to be cleaned to get rid of the yuk for electrolysis and coated.

Hi-Run WD1138 ReplacementTire, 20X10.00-8 4PR have arrived

Ordered 3 of these tires from TSC.  Two for the DYT4000 and 1 to mate with the one from DYT that still holds air.  This mis matched pair may be used on the Murray 46/18 if it comes to life.

I was thinking they would have been a bit stiffer but they are as flabby as most 2 ply.  Having trouble getting them to inflate once mounted.

Cut sticks to hold the sidewalls out.  After resting this way for 2 days the can be mounted.  Tried twice at one day and it did not work.

Unfortunately they are smaller than the Carsile with the same size numbers.  But still good tires at under $50 and they do say they are 4 ply.

This is a comparison between the 20x10x8 Carsile Turf Master and the tires on the rear of the Murray 14.5/42.

14.5/42 with one new tire.  The other wheel got the 20x10x8 that came with the DYT4000.  A little mismatched but not bad.

But his rear end is now making noise.  I don't recall if it started with the tire change.  Should put the small ones back on to see some time.

The DYT4000 got 2 of these new   tires.

Murray 12.5/40 End of the trail ?

The 18 HP opposed twin has been moved to the the 14.5/42.  So has the seat.   The front tires went to the 14.5/42 and the rears to the 18/46.  The gas tank is temporally on the 14.5/42 but does not really fit.

The transaxle has a worn axle bushing.

The transaxle input pulley is wobbly. I don't know if it is the bearing that supports the input shaft or the splines on the pulley.

If it were not for the fact that this tractor has a hood I would junk it for sure.

Murray Madness and Deck Repair

Found a hornet/wasp nest behind the 18/46's gas tank yesterday.  We killed them with spray and today I took both the 14.5 and 18/46 to the car wash.  The looked much better when wet.  Maybe a wax job some time down the road.


The 14.5 goes to the shop shown above to have its engine removed.   The 18/46 goes to the other shop with the air compressor to continue trying to remove the flywheel.   The starter has failed and need to be removed and fixed.  One bolt is under the flywheel.

The axle bushing is shot on the 12.5/40 so I am going to move the 18HP twin from it to the 14.5/42.   I have the decks off both because I had intended to use the 42 inch deck on the 12.5/40.  In time I plan to fix the axle bushing and repower the 12.5/40 with a single cylinder engine so it can be used with its hood.

The 42 inch deck needed some welding.  Other than the damage to the edge the deck is in overall good condition including the spindles.

There was a break at the discharge chute .  A bit of hammer and dolly work put the metal back where it belonged so I could weld it.

I used the HF 90 Amp flux core for this.  Worked well considering I do not know how to weld.

Rode hard and put away wet.

I used rebar to reestablish the edge of the deck,  To weld this I used the HF welder and should have used the stick welder.

 Need to take more pictures.
