Engine oil strainer stud bolts?

Do these 6 bolts go all the way thru the case mounting area? Can they be replaced with a bolt with a cap from the inside the case out, so the strainer and plate can mount?

Got an oil leakage problem and there are regular 10mm & 11 mm bolts holding the plate on. One of the bolts holding the plate on, not bolt studs, appears to have stripped the case screw hole and won't tighten up. Any suggestions would be welcome.

Thanx

Most are held on by studs with a nut on the inside. Double lock the stud, take a magnet and get the nut out then replace with new ones. I use locking nuts on the inside. Hope this helps

Yep, they are usually just M6 studs. One of these is a little longer than the others. It goes all the way through the case and holds the oil pickup tube in place. That one will definitely have a nut on the backside. If the threads in the case are stripped, you can drill out the holes and use a M6xM8 step-stud. You drill out and tap the case to M8x1.25 and the put the larger end of the step stud into the case. That leaves the M6 half sticking out to secure the screen and drain plate as usual. Better Ace Hardware stores usually sell these step studs.

Good info there Eric. I just pulled one of those step studs out of an old 40 horse case. Another tip for you is when you put the studs back in, you should use some locktite or thread sealer that can also be purchased at your local hardware or parts store. This will insure no oil leakage from the threads of the stud.

You guys are awesome. Thank you all for the info, especially Eric and the photo. Once I get it started, hopefully today with a new (number 3) fuel pump will check the leak further.

Be safe.
