Stuck Pulley

Recommended Posts

I'm currently performing a re-power on my 6212.5, going from the stock 12.5hp to an 18hp from an old (but good running) Murray. It's a drop in swap as I've already got it running in the tractor, but I can't get the old drive pulley off the original motor without ruining it. Would anyone be willing to share some tips with me on removing it unscathed? The motor is currently straddling a pair of saw horses.

With a puller attached with moderate tension applied, try a little heat directly on the pulley while also tapping on the end of the shaft witha ball pein hammer. All this is after a good soaking with a good penetrant. :)

If the pulley is steel you can really heat it if it's cast iron CAUTION. If you can get bars behind the pulley supporting it with the engine hanging down and the shaft straight up then use impact on the shaft end. You could also get 1 or more people to hold the pulley and tap the shaft. Patience! Penatrating oil can take day's or longer and every time you heat it you lose that.

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
