New Old stock

[Tomk 1]

So questions 

I found a new old stock 42 Rear discharge stamping.

I'm going to switch everything over from my old deck that I need to convert this to what I need. 

The difficulty I see right now is I will have to get out the welder to attach the new rollers from my old unit.

Anybody got any suggestions I'm open.

 

My question is before I start I've already ordered a new spindle for the one that's missing. 

What can I do to make this last forever? What can I paint on the inside of it? What can I do to the spindles? Anyone have any suggestion? Changes blah blah blah?

If you want it to last forever, build a ramp and run the tractor up so you can clean the deck completely after every mowing.  Coat it with oil for long periods of storage.

Tom - I do not see the area where to rollers are missing....

Preserving the underside - there are several methods. Some spray it with POR-15, some use spray-on truck bed liner, some do the used motor oil rub down & hot sun soak-in.

I prefer to wash out the underside with a blast of the garden hose, run the deck after to move the water out, & let it sit in the sun to dry ANY time the grass is even the slightest bit wet. Keeping the blades sharp & the spindles greased is the key.

Welcome to Red Square.

If I see your model number 05-42RY01 correctly it is for the 600-Series Zero-Turn mowers.

In case you need it click on the image of the mower deck.

@Tomk  picked up a very similar  one year's ago , close to new , first thing i did ?  clean out and  re grease  every related bearing  with  lucas , x tra hd green chassis grease  , guess what ?  never had  any bearing  whine / noise or failure , also did my  mule drive bearings , and pto cone inner needle bearing . spin up is smooth  quiet easy . if you  don't do this now  , rest assured , it will  come back at you  , have a regular  usage  / maintenance  that  has been bombproof , also  zero deck  rot , pete

I have a zero turn with a standup deck that I clean every time.  The ONLY time I had no significant buildup on the deck underside was the time I mowed with the grass sopping wet.  Usually I need to do considerable scraping with a sharp putty knife and mowing when very dry doesn't have a lot of buildup but it takes more effort to remove the hardened stuff.

Thank you very much. I think I'm going to follow that advice.

@Tomk  thanks for the shout , all those bearings have , easily  removable  grease side shields , small flat pocket  screwdriver  , or  smallest flat  putty knife , they are always  reusable . be delicate , wipe out original , lube, carb cleaner flush, then hand pack every related bearing ,replace shields , reinstall. its the hi stress / heat rating  that insures bearing life , when a bearing  starts to WHYINE , WITH  DRAG NOISE , its telling you its LUBRICATION is  failing , none of my tractors do that  . that  pto  inner needle bearing , also needs a careful clean out , same lubrication failure , VEY LIGHT  AMMOUNT OF  LUCAS GREEN , excess flings to clutch facing , want to avoid that  , spin that up by hand to verify  , total ease of movement , we are at opposite  ends of the maintenance  zone , so we both see , something different , I also picked up a very low hr , deck years ago , did the very thing  I am suggesting  , never had  any related  failure on it , glad for you , pete

What wheel horse do you plan on putting that on?

I know it's not the proper one for my wheel horse but the stamping is the same the pressed metal.

Thank you so very much. You seem to be very knowledgeable so I'm going to ask you another question. 

So I know YouTube isn't always my friend. 

However, I was watching a video the other day and they removed and left off The inside dust cover from the bearings so that when grease was pumped into the fitting it could enter the bearings. 

 

Do you think this is a good idea or is it just some kind of disaster waiting to happen. 

 

My opinion is they're sealed bearings so there's no need to grease them. It would never get to them unless you do what this gentleman said? 

 

Anyway, I would love to hear your two cents.

 

So I haven't started the process yet.

There are valid arguments for and against this. I fall in the “get good sealed bearings, confirm good grease is in there, and leave them sealed” group. This might involve injecting a known quality grease myself before installation. Keep in mind that a good bearing does not have to be packed solid with grease, in fact solid packing is not advisable since it can obstruct the bearing carriage. 

My objections, to the “leave one side unsealed”  option are that it is hard to know if grease is really reaching the bearings, Interior voids in the fixture may need a LOT of grease, there may be openings where grease can escape and cause a mess, and does “old” grease actually leave the bearings to be replaced by “new” grease (and where does the old grease go, anyway?).

I applied truck bed liner on my deck about nine or ten years ago and it is holding up well.

Thank you very much. That's what I'm thinking about using.

I can see all of your points. 

The guy in the video his theory was that the grease warmed up during operation and would flow around

I agree with many of the prior comments which are more about deck maintenance after use rather then some type pre-use preparation -- Yes, you can use various underneath shell surface treatments but i believe its the underneath maintenance over the years that is more important -- i see photos of decks for sale that have had almost NO grass cleaning --- thick buildup to make me wonder sometimes how the blades even spin or how grass gets discharged ??

i suggest sharp blades - don't mow wet grass which sticks to shell - run throttle at top rpms - and clean underneath regularly -- either pressure wash, hose - putty knife etc --- and routinely rub or spray on some type non stick treatment - Fluid Film spray, WD 40, or some people just use motor oil - new or used? ( see photo )

Also clean loose grass debris off top of deck cleaned from pulley covers and around pulleys and belts - reduces friction wear and tear and rot - and don't leave tractor/deck outside to prevent water rotting top of deck --

Lastly, if you do not have deflector flange for rear discharge - suggest, you get some vinyl base cove molding and attach with carriage bolts - that will help keep rear underneath of tractor cleaner

good luck
