How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
With the engine cold, tighten the cylinder head bolts, in sequence in 2–3 steps. Final torque on bolts 1–10 should be 65–72 ft. lbs. (88–98 Nm) and on bolts 11 and 12, 11–16 ft.
Yes, only hand tight for head studs. Just your fingers or an Allen wrench (when there`s a hex broached into the end of the stud). You also want to make sure the studs are completely bottomed out in the hole and not hung up on some debris or a burr.
We recommend you use torque values specified below: For bolts with a 6mm Thread Diameter: 20Nm. For bolts with a 8mm Thread Diameter: 22Nm.
DETERMINING TORQUE
The general equation for bolt load based on applied torque is T = KFiDb where K = torque coefficient. K is a function of the coefficients of friction and collar friction in the joint, and these are based on variables such as surface finish, coatings, and so on.
Engines in mainstream cars and trucks typically generate 100 to 400 lb. -ft of torque. That torque is created by the pistons within an engine as they reciprocate up and down on the engine`s crankshaft, causing it to rotate (or twist), continuously.
That`s why most owner`s manuals have a torque specification for lug nuts. If you plan to do any major work on your engine or on some major powertrain components, you absolutely need a torque wrench. Overtightening cylinder-head bolts, for instance, can easily cause expensive damage and catastrophic coolant loss.
If the head isn`t torqued down properly, then the most likely failure is of the head gasket, which could lead to loss of compression, the mixing of oil and coolant, exhaust gases getting into the oil ways or cooling channels, erosion of the cylinder head, overheating and warping of the cylinder head.
The number markings are engraved on the top or side of the bolt head. Common metric classes are 5.8, 8.8, 10.9, and 12.9. The higher the numbers are, the stronger the material of the fastener is.
Too much force can cause a technician to strip threaded fasteners or stretch bolts beyond their limits, which can result in loose nuts or cause the bolt to crack and break.
To tighten the bolt or nut use a torque wrench and tighten it to proper torque specification. Walk behind mower blades should be installed between 38 and 50 foot pounds of torque. Riding mower blades should be installed between 70 and 90 foot pounds of torque.
Briggs & Stratton Metric engines require metric fasteners and drivers for the assembly and disassembly of engine components. Unless specified, the crankshaft features and crankcase cover mounting flange remain as SAE threads.
Tighten them to 10 ft. lbs. If it leaks, try 13. Factory specs are for factory gaskets.
