Default What else would you check with Hydro fluid out?
Hi guys new member here. Just picked up a 1974 149 couple weeks ago for couple hundred bucks. Had an older IH Cub many years ago, regret selling it. Anyways, back to the 149 and a question. The tractor is in reasonable good condition. Koehler fires right up and seems to run well. Hydraulic lift operates properly, not sure yet on the condition of the PTO, as the tractor came with a 44" deck, but was not on. After moving the tractor into the shop, and suffering from a slight case of whiplash, the next day I noticed the puddle on the floor under the tractor.

After doing some research, I first checked the check valves on top of the pump. They are the manuals and seem to be fine- no leak here! The pump is pretty clean,and free of dirt and crud. Checked the lines into pump- nothing. Nothing under the rear gasket, or from the filter.

Can't seem to isolate exactly where this leak is!

I'm going to replace the rear axle seals. Is there anything else you guys would recommend checking before putting the new fluid in? Really like to fix this thing now before moving on. It's not a really bad leak, but still annoying!

Thanks!

Places where it can leak would be the cork gasket between the pump and gear case, the trunnion shaft seals, the input and output shaft seals, the axle seals, suction tube connections, filter, internal brake plunger if it has one, and the rear cover gasket.

Thanks guys. Looks like I'm going to have to get more 'educated' with this pump than I originally intended. Might as well replace the cork gasket, do the repair on the tunnion and check out all the seals too. Has disk brakes on the back.

That would leave just the suction tube connections and the bullet holes, hopefully those are in the service manual.

He didn't say that the tractor came from Chicago.

Some info you may find helpful on replacing all the seals and gaskets on a Cub rear.

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.
