Hi guys, can anyone tell me what the torque specs are for the eight connecting rod bolts on a 1953 JD 70? There seem to be no reprint shop manuals available anywhere,...[money making opportunity?]
thanks as always,
Andy

85 foot pounds if it's a gas burner, I don't have the specs for diesel

1-800-522-7448 for the service manual . There are other specs that are also important .

Before I retired, I spent five years locating most of JD two cylinder Tractor service Manuals ..as well as parts catalogues....$$$$$$$ well invested...
Each binder has at least four JD Manuals..

I believe a 1953 John Deere 70 would be a gas model, not diesel, and the nearest service manual for it is the spark ignition 720 service manual.

I'm sorry, I should have said it's a gas burner. I've heard both 85 ft/lbs and 100 ft/lbs. Thanks for responding.

720 gas calls for 80-90 ft. bs torque.

Book shows 208 for rod bolts. Seems kind of high.
I believe 208 would end up with broken/ twisted
off bolts/ nuts.

Believe I'd go along with 80- 90 on the torque.

Guess that was Diesel, not gas.
Still seems kind of high.
