Takeuchi bearing puller and setting tool

[thehomeengineer]

Hi All
Another one for Frank S

The quick hitch on my digger needed a bit of tlc so was removed. Luckily I decided to do this as the seals had disintegrated and the bearings hadn’t been fitted correctly by the previous owner. So first things first new seals, shims and o rings were ordered. The quick hitch was then overhauled. Attention to the bearings was next. Watching several Youtube videos of people removing these bearings was quite frightening. Oxy/Acetylene, die grinders and even sledgehammer. I thought there must be an easier solution.

I decided to make a purpose built puller and setting tool. Which took about an hour to make. Then outside to the digger to see if it would work. I was so relieved that it easily moved the bearings so they could be set correctly.

The puller was made from a piece of M16 (Approximately 5/8”) studding with a top hat bush thread the same size and turned with a slide fit in the bearings. The other end consisted of a piece of scaffold tube faced off each end and a thick 50mm diameter washer with a couple of M16 nuts to draw the bearings out.

The photos will hopefully show how the tool works.

I would normally chuck the used material back in the scrap box for the next project but as this worked so well it has made it into the tool box for future use.


Completed tool


Pulling bearing out


Puller being drawn through housing.


First bearing removed


Setting the bearing to correct depth


Ready for seal.


Seal in place ready for quick hitch to be re-fitted.

Not sure if I just got lucky not having to resort to burning, grinding or the good old sledgehammer method to get the bearings out.

Thanks, I can always use another puller pusher. Sometimes you get lucky pulling the old bearing out.
On some of the much larger equipment I have had to try using a 50 ton hollow bore hydraulic pullers with a 2" diameter threaded rod. At times that was not even enough so a couple passes with a stick weld to the bore will draw them up for easy removal. Re installing it is a good idea to drop the bearings in the deep freeze over night or quick cool them with dry Ice if you don't have that then a C02 fire extinguisher directed into the bore of the bearing will do the trick, of reducing the OD just enough to be pressed in easily
I usually keep these kinds of made tools and of late have started adding descriptions to them lest I forget what they were made for. Someone is going to have a blast at my estate auction after I am gone trying to figure out what everything is.

Frank S I always look forward to your posts as they are always on a different level. Normally cobbled up out of items to hand but always get the job done. I do sometimes have barn/space envy as the space you have is every boy’s dream. Looking forward to your next project
