IH 684 Valve adjustment

[Riversea]

Hi Everyone. Just finished rolling the tractor together after replacing the rear seal, clutch, flywheel resurface, etc. Before I install the engine shroud, I thought it would be prudent to check / adjust the valve clearances. The factory spec is .012 for intake and exhaust respectively, with engine hot. Seems like a step (warming up and polluting the shop air) could be saved if the factory published a cold setting. Has anyone bothered to measure the difference(s) between a hot (.012) and a cold measurement on a 684? If so, what was the cold measurement? Thank you for your reply(s).

Just open the door or run it out the door for a bit till it warms up then check it inside. Could also put a pipe or hose to it to exit the building during running.

Some Perkins use .010 hot, OR .012 cold.

Does it have a block heater? If so, just plug it in.

Suggest !:Check the surface condition of contact at each valve , if worn wont get accurate set. Up .

With I H and many others what they say is HOT is room temp of 70 Plus degrees and to get to Operating HOT this takes a good deal of Working time to get everything up to working temp and on a diesel ya got to work them to get there just setting running they COOL DOWN .
