Grease ?'s

[jellyghost 378]

I am new at this, but I am getting to know my C 101 a little better.  Here are a few questions/problems:

 

What are the square head bolts on different parts of the back axel. They look like they are places that need grease, but they are not zerk fittings.  Am I supposed to do some maintenance related to these bolts?

 

Two of my mower deck spindles are not accepting grease.  I know the gun and my technique are fine because all the other zerk fittings are working.  What should I do about this?

 

There are a variety of metal on metal parts on the machine.  For example, the place where the steering rods (?) engage the front axel and the steering column interacts with the a large gear.  Should these metal on metal parts be lubricated?

 

Thanks!

  I think you are referring to the set screws that lock the hubs to the axles.     No lube required.

 Remove and replace the zerks .  They are probably clogged with hardened grease.

 Steering rods?   I assume you are talking about the spindles.  There is a grease zerk in each side of the axle that lubes the spindles.  If you are talking about the tie rods, they do not have zerks, but you could squirt some oil up in them.      There is a zerk on the steering block that should lube the sector gear.  There is also a zerk under the center of the axle that lubes the pivot pin .

 

Thanks!

Good answers from Ed, I'm just going to add a couple of extra comments to his, mine in red.

  I think you are referring to the set screws that lock the hubs to the axles.     No lube required.     You should make sure they're tight to the axle.

 Remove and replace the zerks .  They are probably clogged with hardened grease.     Replacing the zerks is probably the easiest thing to try first.  If that doesn't work, there's a procedure somewhere here on RedSquare (maybe a service bulletin, I'd have to look) that describes how to loosen up the passages inside the spindle to allow the old grease to exit more easily.  Which deck do you have?

Everything that tunahead72 notes.

 

A few points. If lifting, using a jack, the front axle, careful of the pivot grease fitting. I've seen too many broken front axle Zerk fittings.

I always use Never-Seez thread protection when assembling any bolted hardware.

 

Lowes is a good place for new hardware. I try to always use stainless hardware and Never-Seez if replacing hardware.

I like PB Blaster if just spraying, part of my PM (preventative maintenance) routine.

Just download, then read the manual for your tractor...  

it will reveal every specific thing you need to maintain on your tractor.

Thanks everyone!  

I looked at the manual before posting, and I noted 6 zerk fittings (excluding the mower deck).

I didn't see anything about greasing other friction points, but it seems like a good idea.  I probably shouldn't use a grease gun for this.  Do I need an old fashioned can of oil?  The type that oils the tin man in the Wizard of Oz?

Why doesn't the back axle need grease like the front axle?

Rear axle is lubricated by the transmission fluid.  As to oiling rub points you have 30w for the engine also works for the oil can.

A needle point adapter for your grease gun will work well for injecting some grease into those areas on moving parts that do not have zerks....ie foot pedals, tie rod socket ends ,bushings,  and even sealed bearings by lifting up the seal.
