Draggin Wagon Posted September 12, 2021 Share Posted September 12, 2021 A friend is having hard time finding a flywheel for a late 1980 EM6-285R engine in a B Model. This flywheel is a pocket style for 15" single disc push clutch. When flywheel is laid front side down on flat surface, starter ring gear touches the flat surface - very different than 673s used in B Models. Any help would be appreciated.

mrsmackpaul Posted September 13, 2021 Share Posted September 13, 2021 Probably a dual plate flywheel machined out to take a single 15 inch clutch I have done this before on GMs to get things to match, I doubt a 285 was ever offered with a single plate clutch as I feel the torque would of been way to much for reliable service in a working truck Paul Quote Link to comment https://www.bigmacktrucks.com/topic/68086-fly-wheel-question-from-fuzzy-buzzard/#findComment-479842 Share on other sites More sharing options...
theakerstwo Posted September 13, 2021 Share Posted September 13, 2021 The B model never came with the 285 but could have been put in later.It has same bolt pattern as the 237 and old 673.Some one done what i did and install a latrer engine but used the push to release clutch.That way no problem with linkage.

Draggin Wagon Posted September 28, 2021 Author Share Posted September 28, 2021 Anybody have any gas engine flywheels that they could check the casing number? So far nothing is showing up on diesel flywheels.

theakerstwo Posted September 28, 2021 Share Posted September 28, 2021 Years ago i had a machine shop build a flywheel for me for some old engine and was simple for him to build.
