Hi, new member here.  I need some help.  The left outer spindle assembly on my Honda MM52 mid mount mower deck (part # is Honda 72701-769-M01) has seized and the local machine shop can't get it apart to rebuild it.  10,000 psi wasn't enough to do the job.  Honda discontinued the part in 2008.

 

I hope (unrealistically) hopeful that someone here may be or know a dealer with an old one in stock, or may have an old and unused mower deck.  The only other alternative is to get a spindle assembly from some other deck and try to make it work.  Any advice or assistance will be gratefully appreciated.

 

Thanks in advance.

 

Bill

Welcome to GTT. Post some pics of the spindle to give us an idea of what you are working with. Check with our sponsors. Joe was able to help me about 4 months ago with some obsolete parts. Let us know how you are making out in afew days. Good Luck, Rick

It stinks to have a perfectly good piece of equipment be made obsolete by something as simple as a bearing.

Back out the grease zerk and start loading it with penetrating oil. I've had some success by clamping the housing in my vise and working at the spindle with a pipe wrench until it broke loose.

Did you put any heat on it while in the press? That may help. Obviously you don't want to damage it any, but you are out of business now anyway so you may as well give it a try. You don't really have anything to lose.

Just be patient. And gentle. More pressure in a press can be dangerous. Too much force can turn things into shrapnel. I know that first hand. A grad student in my materials lab in college decided it would be cool to compress a piece of one inch diameter cast iron to failure. We are lucky we didn't lose somebody in the process much less a body part. I didn't see it happen. I left when the dumb a came up with the plan.

Worst case you replace all the spindles with something different and you will be back in business.

Good luck.

Boats.net has NOS parts for all Honda tractors. I bought all the parts for a complete motor rebuild from them for my H4514. I could not find parts anywhere else.
