Mower deck Stuck Bearing

cfmechanics said:
I just quickly went out to my workshop to take a couple of pictures. One is from above with the bearing stuck on the shaft. Another is from the side with a line pointing to where the bearing keeps getting stuck.

Hope this makes sense to someone... :laughing:

That lip isnt meant to be there.
Its been damaged probably by being hit by a hammer getting the pulley off.
Emery paper, file or grind it to get the lip off for easier removal.

I would say the same thing if I was just looking at the picture, you may be totally right but there is a perfectly round lip all the way round about 5-10mm down the shaft. Before I grind it off are you totally sure it isn't suppose to be there?

I really appreciate the help, I just don't want to do something and then regret it :laughing:

Just grind till lip is same thickness as rest of shaft.
 
Like he said... likely from someone beating the end with a hammer...
A flat file will make removal easy ... :smile:KennyV
 
The lip you are talking about I see it is where the pulley or a flange has been. What has happened is that the pulley has worked loose causing the ridge on the shaft. To remove the ridge take a peace of fine emery and rip it into about a 1 in. wide strip and 1/2 rap it around the shaft shaft and sand down the shaft. You still want that press fit so don't over do it. When you reinstall your pulley if it is loose on the shaft use something like JB weld to tighen it. If anything is loose it will just get worst with use.

It looks to me as if someone at some time has used a hammer on the shaft end and mushroomed it. That can be fixed to precision in about 5 minutes with a good bench grinder and emery tape. Some skill will be involved too.:biggrin:

If you don't have a micrometer to measure with use an adjustable wrench (Crescent) to compare diameters of the normal and swollen area and to check for round or out of round.
 
Yes, the pulley has been off previously because someone has drilled puller holes so that could explain the lip which is on the shaft.

Thanks to everyone for explaining the best ways of removing this lip from the shaft, hopefully this time tomorrow I will finally have that bearing off and a nice smooth shaft.

I agree with you sandburranch, it has been mushroomed but I must admit I did add to it in a despirate attempt to get the bearing off. I will defiantly use my bench grinder to get it back to the right size and shape.

Big hammer, bench grinder, and a smooth shaft, boy you sure got a different idea then I do as to what is smooth. If it was my job and needed a bench grinder it would be going to the recycle pile and get a new shaft. If the shaft is that bad turn it in a metal lath if you want to save it. Everyone has there own way of doing things. Sounds to me you can do the job over in about a years time because you are doing very poor workman ship.

The bearing are a light press fit on to the shafts and housings. The proper way would be to use a press with adapters to fit the bearings. Seeing I don't have this in my shop I use a large hammer and brass rod to take it apart in a mechanics vice. Once I have everything apart I clean every thing with sand paper. To put it back together I use a hammer and the vice as a press where I can. I use sockets to push on so when installing the bearing I am pushing on the bearing races and not the bearing balls.

Why would a light press fit, bearing to shaft, be needed?
