Do you put assembly lube under main bearings?
Do you put assembly lube under main bearings?
No, only lube the bearings on the journal side (where they touch the crank). You do not want to lube the side that touch the rods, or where the mains fit into the block.
Where do main bearings go?
Main bearings are mounted in the crankcase. A main bearing consists of two parts: upper and lower. The upper part of a main bearing commonly has an oil groove on the inner surface. A main bearing has a hole for passing oil to the feed holes in the crankshaft.
Should I use assembly lube?
No! Assembly lube is a must for anything you are putting together in your car or bike. If your thinking “assembly lube is just for professionals”, or “assembly lube is just for brand new motors” chances are you’re in for some premature failures for components you’re putting together.
Can you use too much assembly lube?
It definitely will clog up an oil filter. Use STP, EOS, or the Lubriplate 105 on bearings. The grease is better if the engine is going to sit for a while before being started.
How long does assembly lube last?
If it was inside in a protected environment, then I would expect that the assembly lubricant would last at least six months – probably more. The main concern would be the tappets on the camshaft.
What kind of head does a Chrysler 318 use?
The wedge heads (first used by Chrysler on the B engines) were far smaller, and lighter, than the old Hemi and polyspherical heads (318s with the poly heads are still often called “wide blocks” though the block itself is about the same size as that of the LA 318).
What kind of engine does a Dodge 318 have?
Electronic fuel injection finally came to the 318 (and the 3.9 V6 based on it) in the 1988 Dodge trucks (bu tnot cars). This was, in contrast to the Imperial’s system, quite conventional, with a single dual-injector unit in the throttle body (one injector for each bank). Power output rose by a much-needed 20% to 170 hp and 280 lb-ft of torque.
Is the Mopar 318 cast crank externally balanced?
The 318 is not externally balanced in either A-engine or Magnum versions. The forged-crank 340 (1968–1971) is not externally balanced, but the cast-crank 340 (1972–1973) is externally balanced. When building an engine, consider your performance targets.
What’s the difference between a 340 and a 318?
There were many differences between the 340 and 318 apart from the bored, which made the 340 far more powerful than the everyday 318. The six-barrel version of the 340 had extra material in the bulkheads for strength, allowing the use of 4 bolt main caps; it also had a different cam and heads.
