THE BOTTOM LINE
THOUGHT your readers might like some advice on putting together a bottom end. There are lots of articles out there, but they’re mostly aimed more at the credit card-wielding horsepower junkies. Our engine build, by contrast, is on a dollar diet. Enjoy.
Firstly, before starting any work on the bottom end of an engine, whack a couple of sangas into your brother (ham/cheese/tomato).
In our engines we don’t run any thrust washers. They are money-hungry little buggers and a total waste of time. Why would anyone run brass in an engine, unless it was the bloody Queen’s Rolls-royce? By leaving the thrusts out it solves cooling issues too. When sitting at traffic lights with your foot on the clutch, the snout of the crank moves closer to the cooling fan. Better cooling.
To mount the crank in the block, many city types and pretty-boy race teams use expensive assembly paste. They probably brush their teeth with Colgate toothpaste and drink Earl Grey with Prince Charles too. None of that wastage out here at Dunedoo. When I take Tanya out to dinner at Micky D’s, I pocket all the tomato sauce sachets, and dead-set, they work a treat. We lay the sauce down on the shells and the crank goes in as slippery as Clive Palmer’s thumb at a KFC buffet.
Once the crank is in place, we tighten up the main bolts, using a good shifter and a 100kg fella. Then we zip through and write red ‘X’ marks on each of the main bolts. That is a trick I learnt from years of spinning spanners in dealerships, workshops and shitshows. That guarantees the tension on each one is exact and true. Makes the warranty department at the dealership happy, too.
