Makita DCS520, bar studs loose

[NickJW66]

Hi everyone, have a poorly Makita DCS 520 with both stud bolts that hold the bar on loose in the crankcase. The metal is cracked around the hole edges and won't allow the nuts to tighten up to hold the bar. Can it be fixed, or do I replace the crankcase?

 

Thanks for any hep.

Alloy crankcase ideally would need replacing. Repairing cracks around the mount holes is nigh on impossible, and something like a bar stud needs to be 100% secure before you use it.

Get some pics up. The bar studs would be typically thread locked in place but if the thread is really bad you may be able to helicoil them but depends on how bad the cracks are.
