While changing timing belt (TB) on 1993 LS400, had difficulty keeping crankshaft (CS) pulley from moving while torqueing CS pulley bolt to 181 ft lbs. Ended up rotating CS around 1 rev by accident w TB attached to CS timing pulley only (TB was not yet connected to either camshaft timing pulley). The TB bunched up on left side (driver side) of CS timing pulley (inside pulley w teeth) and broke the left tab/guide on front of oil pump body.
Looks like this tab/guide (its shaped like half circle) on lower left of oil pump just outside of CS timing pulley/helps keep TB positioned against CS timing pulley at start when attaching TB to CS timing pulley.
With this damaged tab/guide on the oil pump, will the TB stay aligned and properly tensioned and function OK? Do I need to replace the oil pump? Can I do this w/o removing engine?
Also, how do you keep CS pulley from moving while tightening crankshaft pulley bolt? Do you need a specail tool? If so, where can you get this tool?
Appreciate your reply/comments...THANKS! :)
