Hello Listeroid members,

I'm a newbie here looking for some advice & guidance.
I've been given an HRS6 to rebuild by my employer, the engine overhaul kit, main & big end bearings all arrived in our workshop yesterday along with a brand new workshop manual.

I remember some 25yrs or so ago assisting a very well experienced diesel engineer with setting the bump clearance, but my memory is cloudy, hence, I approach the sage ones of this forum to refresh my memory.

While measuring the "bump clearance" (using 1.5mm lead wire), the manual says torque down the cyl head and rotate the engine twice, remove cyl head and measure lead wire. Should a gasket & any shimming be fitted to the head for checking purposes, or is the figure (0.042"- 0.045") for absolutely nothing fitted between the head & barrel?

One more thing, I'm finding it impossible to source 1.5mm solder wire by Monday afternoon, the best I can do is 2mm or 3mm, will this do?
I hope the above all makes sense.

Thanks in advance for any help you may offer.

Regards,
Richard.
