    Oil filter cap - studs/bolts

    When changing the oil filter on my gs750e, the threads were worn and wouldn't hold the nut. I took out the studs and fitted ss allen head bolts instead.
    Will this be a problem?

    I believe it is not recommended to use bolts because it makes you have to screw in and out of the threads more often.

      It won't be a problem in the short-term, but, as stated, everytime the oil is changed, the bolts have to go into and out of the block and could, over time wear out the threads.

      I'd just get some new studs and nuts. Heck, they're really cheap.

        Yes ok, I'll get studs and nuts instead then. I'll reuse the engine oil since the bike hasnt moved since I changed it.
        Thank you for your swift help, both.

          Save yourself the trouble and just change them back to studs at the next oil change, when you take the filter out again.

            as long as you use copper anti seize compound, bolts will not give you any problems

              It took many years for me to finally work out why the threads on those oil filter studs strip. I always changed the oil when the engine was hot, so found it difficult to work inbetween the exhausts. My theory is that tightening the nuts against the considerable spring pressure of the cap results in too much force being put onto that small size fastener.

              I now wait until the engine is much cooler and use a glove on one hand to push the cap right up against the oil filter housing, then turn the nuts on all the way by hand (there is no more spring pressure, so it is easy), and use a wrench just for final tightening.

                I think it's more that Suzuki made these studs out of pressed sawdust and cheddar cheese. They wear out and strip unbelievably easily.

                Also, don't forget the tender loving care of so many POs, who like to snug things like this down with a 1/2" breaker bar.


                Anyway, yeah, just get some studs and replace at the next oil change. No need to take it apart again. And yes, bolts will eventually wear out the soft aluminum threads in the block, even with antiseize. Why risk this at all?
