Jim, Welcome to the Forum. The Cubs don't have a water pump, they cool on a thermosyphon system. A 50/50 mix of water and antifreeze is recommended. The rear wheels have their oil in the bull gear pan. There is a plug for adding oil, but if you don't know the maintenance history of your Cub you should probably remove the pans, clean and refill. For the front bearings, I'd suggest unscrewing one of the hub caps and seeing what the condition of the grease inside is. Stan's link to the manual will give you info on other places that need oil/grease that are often neglected. There is also a Blue Ribbon service manual that gives more details on Cub repair, etc. Let us know when you have more questions.

thanks for the info. Next ? on the rear wheels I filled up with 90 wt. oil on each side do I need to do anything else there? Also had to remove old bowl for gas tank and put in a filter 3/8 line is this ok? thanksjt

No.

Had to remove old bowl for gas tank and put in a filter 3/8 line is this ok?

This is a topic for discussion. A lot of folks disapprove of using "rubber" fuel line. Stating that "rubber could be source of a fire. Others have use the "rubber" fuel line for years with no problem.

I strongly suggest that you download and read an operator's manual from cover to cover to get to know your tractor. They cover all the lubrication points and there are probably a few that you will never be aware of until it is too late. Like your fan hub, for example, which you may have mistaken for a water pump. It has a very specific procedure that needs to be followed to keep it from slinging oil all over the place. Follow the link and pick one that is close to the year you have, although they are all basically the same. The files with "OCR" in the name means they were scanned with a optical character recognition option that allows keyword searching and in general they would be better quality scans with smaller file sizes.

sorry to get back so late ? from anyone who wants to send it on radiator. I have antifreeze in the it. when I run the tractor for 30 minutes it starts to come out of top and settle on the steering housing? is the cap bad? or do I need to drain and clean radiator?liquid is about 2 inches from top at fins? thanks for anyone's info? iimt /jptpope......

These are non pressurized systems. They will find their own level, usually at about the top of the fins. I'd continue to run and watch it, will probably stay about where it is now. As Bob suggested, the manuals are a valuable resource, either the PDF Version or printed copies from TM Tractor or other sources. I use both. I read your post about working on this with your Grandson. I have three Cub Buddies, aged 10 mos. to 11 years. You're gonna have a great time making memories for both of you. John

The radiator should be filled so that the fluid touches the tube that you see when looking into the top. Any more will get spit out of the overflow tube and will pool around the steering gear. It will stop ejecting the fluid once the proper level is reached. Look in the top and if you can see the fluid below the top of the big tube you are probably okay.

[jptpope]

should the radiator be drained and refilled and is the drain threaded at the bottom? thanks jt

There is a radiator drain on the bottom of the bolster/lower radiator housing. It's suppose to unbolt. If it doesn't you can remove the coolant manifold on the lower right side of the engine block.

If you decide to replace the antifreeze, it's a good idea to flush the engine block and bolster/lower radiator housing.

When to replace coolant/antifreeze. Some vehicle manufacturers recommend a cooling system drain every 2 to 3 years. Some go as long as 10 years before replacing. Check the recommendation by the manufacturer of the antifreeze you purchase.
