Hi guys,
I have roughly 75% of my D4-7s transaxle torn apart. I've come down to the bearings and they need to come out. What do you all use to get them out? Thank you very much.

I would imagine most people use a press to get them in and out.

How about a slide hammer? If you have an Auto Zone near you, they loan out things like that for free.

You are speaking of the bearings inside the transmission? They make bearing pullers for blind holes that expand right behind the bearing through the center hole. Both in slide hammer type, & puller type.

Here is the better style for blind holes: http://www.harborfre...ller-95987.html

Daniel would you use these to pull the axle bearings and seals too?? So far I have been using a steel rod and knocking them out. Would rather come up with a easier way....with less potential for damage.

Yes those bearings. For example, my rear pto has that bearing behind the rubber seal/plug. The pto is still there and the bearing is stuck. I need something to pull that bearing out while there is still something in the middle. The blind hole puller with the slide hammer looks like a winner for bearings with nothing in the middle though.

I saw this from NAPA

I just don't know if that would work for me or not.

Titus, if you look close, that puller requires maybe 3/16" clearance behind the bearing to use. I have one similar to it, and it's not good for a lot of bearings in blind holes because there's little to no room behind.

Thank you Daniel. Glad I didn't order it then. What kind of puller would I use for these bearing where something is taking up space in the center? Like the PTO for example.

Daniel, I have something similar to that HF, except mine is Snap-on and has about 15 or more different sized bushing pullers in it. Has two different slide hammers. Maybe I could sell that and buy another GT?

I would remove the woodruff key from the pto shaft, then pull the seal/bearing retainer plate. Then put the key back in the shaft. Then go to TSC & buy a sprocket hub (weld-a-hub) that fits the pto shaft. Slide this up over the key far enough that they new hub's allen set screw just passes the key, then screw it down. This will lock the hub behind the keyway. Then you can either buy or build a slide hammer to attach behind this hub to pull the entire shaft along with the bearing out.

Sadly the key is MIA, was since I bought it. Plate is out.

A hub like this for example?
http://www.tractorsu...in-bore-1170662

But one that fits the pto. I have a slide hammer I use for rear axles pulling the axles out of club cars, etc. I would just now have to find a photo of the exact part I need to make it all work.

The key is a std woodruff type key. Measure the width of the slot, then TSC should have it. Yes, that type hub is what I spoke of. You could just drill a divet into the pto shaft less than 1/8" deep with a 5/16" drill bit for the allen set screw to seat into.
