How do I switch a crankshaft

Disconnect the battery. Remove the spark plugs. You will need to remove the engine and transmission from the vehicle (unless you have a lift, in which case you only need to remove the transmission.). Separate the engine and transmission. Remove the flex plate (flywheel). Remove the serpentine belt and crankshaft pulley. Remove the timing cover, timing chain, and crankshaft timing gear. Remove the oil pan. You may have to remove the oil pump for clearance. Remove the rod bearing caps. Keep them in proper sequence. Remove the main bearing caps. Keep them in proper sequence. Remove the crankshaft.

You will need new rod and main bearings to replace those already in the vehicle. You will need a new oil pan gasket and timing cover gasket set. Depending upon mileage and age, you may want to replace the timing gears, chain and guides. You must know all proper torque values for the crank and rod bearing caps, flex plate, and timing cover.

As you can well see, this is not a job for the auto DIY novice.

My Honda 2004 CR-V develops a howling noise from the rear of the car after about 20 miles of driving. I have changed the rear differential fluid, and burnished the differential clutches per Honda Service...

A howling noise from a diff is an indication of the gear mesh( pinion to crown wheel) is not correct. Several reasons being worn pinion bearings--loss of preload on the pinion bearings --- crown wheel carrier bearings failing ---not sufficient preload on the bearings---wear on the teeth from incorrect diff oil in use. or simply wrong diff oil. The grade should be 80w90 OEP for normal or special oil for limited slip diffs.

Spun bearing

You are up for an engine rebuild. Remove the engine and turn up side down in a stand. Remove the sump and find the failed bearing by taking off the big end caps. If you find a con rod damaged you will have to remove the head and that piston and replace the con rod. If it is a main bearing that has spun you should only have to replace the crank shaft and fit new bearing shells Either way you will need another crank shaft. Check the price of a low mileage engine from a wrecker as it will be quicker and possible cheaper in the long run

Was told that my lower end is junk. Seams fine to me but not sure on how to check with out splitting the Case. Is there any little tips or tricks. The rod has alittle side to side play but not...

Hi, spin the engine, with the piston removed hold onto the top of the con rod and start to turn it keep spining it and listen how quiet and smooth it is, the main bearings when worn will sound noisy and feel rough, the big end may lock up when worn,bring the con rod to the top, in the middle of the big end where the pin holds it to the crankshaft, you will see a cut through the rod where the bearing is visible inspect the bearing for condition, the bearings are held in a cage which when worn breaks and the rolers become loose, this may cause the bearing to lock, also check for up and down movement, at all parts of the stroke

How can i tell if my crankshaft bearing is going out

Hi, if the big end bearing fitted within the con rod on the crankshaft fails it is accompanied by a knocking noise when the engine is running, when the engine is striped and the crankshaft is out, movment of the con rod in an up and down direction while grasping the conrod between finger and thumb indicates big end failure, youmay also notice while rotating the con rod that it locks up, more so in 1 direction. Visual damage bearing cage failure visible from within the oil cut out on the big end of the conrod,
Crankshaft main bearing failure, the main bearings are fitted within the engine cases 1 left and 1 right, failure of this bearing would be movment of the crankshaft ends within the cases, accompanied by a rough vibrating sound.when running,
Hope this helps paul

How to remove lower bearing on connecting rod in a yamaha yz125.

I'm not 100% sure because I have'nt had much dealings with yamaha dirtbikes but I do know that on Hondas and Kawasakis there are no rod caps to remove the rod from the crank, the crankshaft actually splits and the rod slips off. They are a very tight press fit and have to be reassemled perfectly or it will throw the whole balance of the engine off. I recommend taking it to the dealer and letting them do it. I know that on my Honda CR 125 instead of trying to replace the lower rod bearing I was able to purchase a crankshaft with a new rod already attached. Hope this was helpful.
