Crankshaft repairs

[Boats&Outboards]

Just removed a crank from a poorly Mercruiser 4.3 ltr V6 (year 2000) which had its main bearings fail, in turn it's lightly marked the crank to a point which it will require grinding back, with the then new correctly sized shells being needed.

Luckily the pistons, bores etc are all spotless so it's worth re-building. Provided the crank can be done of course!

So my question is who do or you used and who would you recommend ? Ideally local to Plymouth or at least Devon/Cornwall.

it's not something we would normally get involved with, normally they just go the the relevant dealer for repair but this one owes us too much to do so.

Hi Peter

Not quite down your way i know (near Dorset/Hampshire border) but we use these guys for all kinds of precition engineering work.

Engine Machining Specialist in Southampton : Saunders Motor Works Ltd

They have recently re-ground the crank of a Volvo Penta D7 for us which decided to ingest it's own sump oil through the turbo seals.....wasn't pretty

They do very good work at a sensible price.

These guys also have done an aircraft engine ( lycoming 0-200) crank for me in the past .....i'd trust them again like a shot .

Update

Spoke with the guys at Paul Inch and been quoted £150 for the re-grind plus bearings. Does that sound reasonable ? It does to me ?

I did my range rover 3.9 v8 crank and that cost arround £100 about 6 years ago so £150 with new bearings sounds good to me

[Boats&Outboards]

That's plus bearings.

We've just been onto another (Yeo & Smith) in Plymouth who has quoted us £80 + bearings. We're going to take it down to them and see what they can do.
