Need torque specs for JD 316

DaveK(IN) · Nov 28, 2016

I am repowering my 316 with a Vangard from the small engine warehouse. The drive shaft connects to a 6 armed adapter on the end of the flywheel similar to the one on the original Onan. What should these bolts be torqued to? Any other advice for this project? The old engine is out awaiting chassis cleaning before installing the new one.
TIA- Dave K

NOT sure what you mean by "six-sided", as I believe those adapters have two separate FOUR bolt patterns, four to attach the adapter to the engine, and four to attach the driveshaft to the adapter.

ANYHOW, here's the original OEM torque "specs".

When in doubt and instructions for a specific joint aren't available you can use a bolt torque chart like the one at this link. There's a lot of variability in the resulting clamp load for a given torque - a hardened washer on the bearing surface or oil on the threads will result in a much higher clamp load than a dry connection on a softer bearing surface - but a chart like this at least gives you an idea.

Thanks Brendon and Bob. You were right, it is a 4 armed mount exactly as shown in your helpful post. Dave K
