Small petrol engine - cylinder head bolt torque?
I forgot when I posted some days back about my elderly cultivator
engine that I would need to know approximately what torque to tighten the head bolts to. It's a Briggs and Stratton single cylinder, side valve petrol engine, 3.5 hp, possibly 1960's vintage. The block is aluminium. Thanks Rob |

GIFFS. -- Dave Baker Well OK - but if you search on "torque aluminum steel" for instance, there are a large number of hits and they aren't really supplying the information in a way that I can understand. Perhaps you could be helpful and do a little bit of explanation for me please. I ended up on this website http://www.thelenchannel.com/1torque.php In the first table, are the materials quoted there that of the bolt or the threaded body ? A bolt if over torqued breaks due to the twisting, whereas an over torqued threaded hole will strip out the threads and these, I would have thought, will not be the same for similar materials, so I'm not sure how to interpret this table. Thanks Rob |

Why on earth would you not google for 'Briggs Stratton head bolt torque'. Rob -- Clint Sharp Because I did so and couldn't make sense of the engine type numbering system, and reckoned that someone here would know the typical torque for steel bolts ( ~5/16") in Aluminium. In fact for once this forum has not been as helpful as usual, and the answer hasn't been as rapidly forthcoming as I expected. It seems that the current attendees are all involved in house building and not the broader aspects of DIY. Anyway with a lot of hunting around on the B & S website I found how to read the engine number, but that wouldn't produce a manual. An email query found another FAQ which showed torques for all engines, which I could then interpret having the engine number. In the end the torque is the same as that shown on thelenchannel website for steel in aluminium, so it is a standard figure, which I had hoped someone here would have known. Considering how many queries come up on this site which are a good deal less complex than this one, and never get told to go and hunt for yourself, I find it somewhat offensive that I got that answer. It would seem the answer is if the question is easy, then answer it and get your name in print, otherwise tell the OP to go and hunt himself. Rob |

My engine was made in April 1967 I learnt from these numbers which in my case are stamped on the carburetor side of the fan housing. If you search the B & S website diligently enough all the info is there - having said that I did find a number for the manual for mine but couldn't get a download. In the end I emailed B & S UK - and of course immediately found the info for myself - and they came back impressively quickly with the head torque I was after.

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Rob G saying something like: Considering how many queries come up on this site which are a good deal less complex than this one, and never get told to go and hunt for yourself, I find it somewhat offensive that I got that answer. It would seem the answer is if the question is easy, then answer it and get your name in print, otherwise tell the OP to go and hunt himself. Yes, but Clint is an arsehole. |

Small petrol engine - cylinder head bolt torque?
We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Rob G saying something like: Interestingly all the B & S tables are in in-lbs (rather than lb- ins!!), so that must be a 'Merican thing. It was common enough here too, for values under 15~20ft/lbs, depending on the specifier's whims. Round about that kind of figure you'd be on a smaller torque wrench because the larger ones wouldn't be accurate enough. |

I've never seem lb.in used for engine stuff though - although my experience is only really with older UK cars. Lb.in is used in auto boxes for some things - I've got a torque screwdriver specifically for this. -- *Artificial Intelligence is no match for Natural Stupidity * Dave Plowman London SW To e-mail, change noise into sound. |

Hours of fun can be had when Haynes mis-appropriately use the wrong units (fairly obvious) or even just give the wrong figures in the right units (not so obvious, but explains why so many cam holders on older Suzukis are stripped), especially on alloy castings. |
