Title: Crank starting....
Post by: 1955CJ-5 on February 27, 2015, 04:05:44 PM: When we put the engine together we installed a front crankshaft nut that would accept a hand crank..

I got a one piece hand crank off ebay about a year ago, but it is too short to reach through the bumper, but turns the engine fine if installed under the bumper..

So I need to lengthen it, and I'd like to make it two piece so I can stow it in the tool box...

I thought I'd cut it in two...find a 3/4" drive socket extension, 6" or 8", cut it in half or as needed, weld the ends on the crank sections and I could then fit the two pieces together when needed....

The crank is really handy for setting the timing and setting valves, and who knows I may even need it to start one day...

Ideas or better suggestions?

That is a 1/2" drive extension in the picture...the crank is 3/4" diameter....

These are not the right size but you get the idea....

How about cutting the original right after the handle bendsï¿½maybe at 20 to 21ï¿½.

Weld the extension to the handle portionï¿½then shape the straight piece to fit in the extension end of the handle.

This idea may not fit in the box though.

Edit::::: Never mind.ï¿½ Just measured to the pulley.ï¿½ 22" to the face.ï¿½ I get it now.

How about staying with the same idea, but picking up, then scabbing in a length of 3/4" round stock steel?

2nd Edit::::Never mind. Now it's probably too long to fit in the tool box. How about you stick with you idea and I shut my trap?
