New billet G JD crank pictures

Some pictures of the new 10.25" billet crankshaft that Brian is currently running in his G JD. Email him for more information on them or call him at 605-359-2043.

Is it drilled for oiling?

What rod bearing diameter ?
There must have been something ground or moved out of the way for the entire 360 degrees of rotation.

Yes,, oil passages are drilled just like an original. We installed it right in the tractor after cleaning the cosmoltien (SP) off it. Mains are standard just like an original new JD one. Splines were tight on the clutch driver and the flywheel snugged up with no problems. Talk to Brian for more details on it. His number is 605-359-2043.

Brian would have the specs for the rod journals on it. I know he picked them up at the local IH dealer here in town when we did the install. As far as making it fit the crankcase,
it took some cutting and grinding to get it in. We have used pans on other cranks before to get clearance in the back. You cut a roughly 4" x 7" hole in the rear of the crankcase
for each journal to clear and then bolt the pans up to the case. Murphy's has rods that give more clearance also that were used. You have to cut part of the top of the crankcase
out and the cam needs to have a proper grind on it to clear the crank. Josh Blackburn does the cams and has worked with us to get the proper clearance where needed. We use
a plate to cover the top of the crankcase where it was cut out for more strength. This plate goes under the governor housing also so it needs to be planed off the thickness of the
plate. The back of the block needs to be grooved out at the top and bottom also for clearance. Not a job for a novice but once you have done a few it goes pretty good. We do
the same procedure for a smaller crank also, not just this 10.25 one. Brian can give you the specs on the rods journals if your interested yet. His number is 605-359-2043.

Who is making billet crankshafts? And can they make one for a John deere A. please email me the info on who is building them.

You will have to go through Brian to get them. We have one for an A blueprinted and are working on different strokes for the G also. The one's for the A should be out a little later. Brian's number is 605-359-2043.
