Pneumatic Hammer

[bc.gold 3,406]

A neighbor had replaced a worn engine in his Mazda pick up truck with another then let the truck sit idle foe a few years and during this time the clutch disk had rusted itself to the flywheel. He now wanted to use the truck but it would not go into gear with the engine running.

 

He had acquired a few estimates from transmission shops to remedy the problem, I'm guessing with the estimate and cost of the tow it was to much to swallow then one day approached me with an offer of $100.00. I gladly accepted the offer telling him that I would be over later in the day.

 

Jacked the truck up then removed the dust cover, had the wife depress the clutch peddle while I placed a large chunk of brass against the flywheel to hammer on with a broken chisel with a blunted end. Turned he flywheel a third repeating the procedure then another third.

 

Climbed out from user the truck then started the engine, the transmission slipped nicely into gear at this time gave a momentary slip to polish to rust free.

 

The job took less than 20 minutes, I'm now asking to be paid and the look on the neighbors face was priceless.

 

I used a 20 lb propane tank filled with propane as my propellent, those rattle cans of paint you use in most cases use the same propellent.

 

Another buddy had purchased a K car that had the same problem, when Ross phoned me I told him that I got $100.00 for the last one I did, on his I accessed the rim of the flywheel via the timing hole located near the top of the bellhousing. Ross had an air compressor we completed the job n less than 10 minutes.

 

I once bought a John Deere model 70 that sat in a field for years and the multi plated clutch disk had rusted solidly into place and would not move, air chisel to the rescue. Unfortunately non of the parts were salvageable and had to be replaced with new. 

 

In my tool box you'll find a short and long stroke pneumatic chisel.

 

The short stroke works good for seized parts, lots of vibration while applying penetrating oil.

I use my pneumatic hammer often.  Having different chisels and such is a must.  I have a good flat blade that will take down a brick wall in a few minutes.  I also made one that is a punch I use for tapping out pins.  Also have a few that are made for cutting metal...great for making lead sleeves.
