DEET wrote:How it is used:



Each end of the crankshaft is threaded.
Find the adapter that fits the threads. It should attach smoothly. Some of them have a 'fine' thread pitch, others have a 'superfine' pitch. Don't end up cross threading it. Use a thread pitch gage if you are not sure.


*******************************

USUALLY, you install the primary gear end first. It probably had a shim between the crank and the main bearing.

*******************************


Thread the puller shaft into the other end of the adapter. Lock it down with the jam nut.

Position the crank in and through the main bearing.

Slide the puller body over the puller shaft.

Place the washer over the shaft. Add some oil to the washer and shaft.
Screw on the puller nut while making sure everything stays centered.

Now you are ready to pull the crank through the bearing.

Slowly tighten the nut. It will draw the crank into the bearing.


The hardest part is knowing when it is completely through the bearing. Sometimes you can tell by looking at the gap between the crank and the case. Sometimes it pulls in smoothly and you reach the final restance.

If it is NOT pulling in smoothly but shuddering as you tighten it, you may have to apply a lot of force at the end and gently tap on the crank half that is being pulled in. This vibration can sometimes help overcome the friction. USE CAUTION.


When installing the case on the opposite side, the procedure is the same EXCEPT for the following: the magneto end of the crank usually 'floats' in and out of the bearing due to expansion and contraction.

So... you will be pulling in the crank until it stops AND it doesn't try to pull the other end out of the bearing.

During this procedure, you will also be busy aligning transmission shafts and tapping them (with a rubber/plastic hammer) through their bearings, making sure the case is going on squarely, aligning shifting fork shafts, etc.

The tool is applying the pressure and you are helping the other components as they slide into place.

This is why it's easier to just send the bottom end to Deet.

Deet, you never fail to impress me with your fabrications! Although they may not be the prettiest of tools, simplicity in both form and function is all that is required to get the job done...

Hee-Hee!!!! [LoL]

I've never used a tool and thought: "you know, this would work a whole lot better if it was pretty".


I have thought: "you know, this would work a whole lot better if it was clean".

DEET. You put the easy in crankshaft installation. How many of the non existant, expensive oem crank puller/installers does this heavy duty tool replace.
