I am an avid reader of CM and al­ways turn to Steve Roth­well’s Tales from the Work­shop first. For the July 2018 is­sue, I was pleased to find that, for the first time, I out­per­formed him! An al­ter­na­tive to Steve’s fix for the thrown drive­belt on the Skoda Oc­tavia is to re­place the clutch, bear­ing and/or elec­tro­mag­net on the com­pres­sor. Ob­tain­ing th­ese com­po­nents is pos­si­ble by mak­ing a note of the man­u­fac­turer’s name and the model num­ber of the com­pres­sor – the sticker on the com­pres­sor will al­low you to iden­tify th­ese (see photo). An in­ter­net search will lo­cate a suit­able sup­plier, then it’s sim­ply a case of wait­ing for the bits to ar­rive. The clutch com­po­nents are gen­er­ally held on by a sin­gle nut and two cir­clips.

I have just re­placed the clutch on a San­den PXV16 com­pres­sor on a Volvo V50 1.6 D2 in this way. The re­pair meant that I did not need to vac­uum out the sys­tem, re­place the drier or re­gas the sys­tem, sav­ing a con­sid­er­able amount of time and money.

Re­mov­ing the aux­il­iary belt and un­bolt­ing the com­pres­sor al­lowed just enough room to com­plete the oper­a­tion. The washer/spacer in the clutch hub needs to be used again and the cir­clips needed to be re­cy­cled, so don’t dis­card any­thing un­til the job is com­plete.
