Default 38 Inch deck spindles

I am starting to get into my 38 inch deck on my Model 70 and have some questions. The two outer pulleys really don't have much play in them. Can i get away with replacing the seals? One side had lot's of grease coming out. I think I need to rebuild the center spindle. It has a little wobble in it. Nothing bad, but too much for me. Should I replace the bearings and bushings, or do I need a whole new spindle?

I don't think the square end deck spindles are rebuildable. I believe you have to replace them. I think Diz cut one apart on here in a thread to show what they look like.

The cast end deck uses tapered roller bearings and is rebuildable. You are thinking of the ST-745 'water pump' bearings which are not.

Well, I have the pulleys off and spindles out but I can't remove the bearings. How do I remove the old grease seals without completely destroying them?

Are the bearings, races and seals available anywhere else but Cub Cadet? I thought I read something about NAPA parts being interchangeable.

Thanks,

Well, I had to pry the seals out, which didn't really matter because they were trashed.

Here is a picture of the seals that were on the deck. There were two different kinds. One is the IH seal and I am not sure where the other one came from. Someone put the IH seal in upside down.

Also have a picture of the bearing race. I cant get these out and I don't want to pound on them. How do you guys get these out? I don't have any kind of press to do it. The good thing is that the only pulley that was loose is the center one. All I have to do to the two end spindles is replace the seals. The races look pretty good on the center spindle, but the spindle has a lot of wear which was making it loose. Can I get away with replacing the spindle and not the bearings? The bearings are still nice and shiny.

I do it the old fashioned way with a hammer and a punch then press the new ones in.

I don't have a press, how did you do yours?

The seals go in up side down, it allows old grease to be pumped out and keeps dirt out. Like I said I hammer the old races out but I like to press the new ones in. I have a press. Maybe you can have a machine shop do it for you.

So on the seals, the rubber side faces up?

I went ahead and removed the races. I'm going to replace them with a new bearing and race set I have. They look pretty bad and aren't real smooth anymore.

You got all the good out of those. Yep the seal goes in with the lip to the outside. I know it seems odd compared to wheel bearings but it works. Just keep it greased. If you put them in like a wheel bearing when you grease them it pushes the seal out of the bore

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
