bbob61 Posted June 8, 2017 Share Posted June 8, 2017 What's the best way to support/lift the engine to replace the front engine mounts on an '88 RD688SX with an E6-350? I am concerned about supporting/lifting the engine by placing a hydraulic jack with cushioning under the oil pan; any suggestions? Do I have to lift the engine from the top with a hoist? That would be more difficult. Trans/rear mounts where relatively simpler comparatively speaking.

terry Posted June 8, 2017 Share Posted June 8, 2017 Just use the jack with a piece of 2X4 as long as the width of the pan and you will be fine. terry Quote Link to comment https://www.bigmacktrucks.com/topic/50120-front-engine-mount-replacement-88-r-model/#findComment-371833 Share on other sites More sharing options...
dogg rescue Posted June 9, 2017 Share Posted June 9, 2017 This post reminds me, on our '88 r model last fall I noticed a weird sound when turning a sharp corner. After investigation it turned out both front mount bolts were gone! The fan was hitting the shroud when the engine would move around. I stuck a couple of grade 5 bolts in it to get by and haven't given it much thought until now.

Lmackattack Posted June 9, 2017 Share Posted June 9, 2017 put a block of wood under it and it will be fine. wider the board the better but it will support the weight.
