Welcome !!
How the guide shoe will rest against the crosshead guide when the crankpin position is 45 degree after BDC, turning in astern direction ?
@@najinkunnath6009
45' after TDC. (Not BDC.)
Depends upon maker and model, crank angle may differ.
In this engine, maker said guide shoes rest on guide @ 45 degrees after TDC.
Thanks.
@@CHiEF_MOEMYiNTSHEiN Thanks.
@@CHiEF_MOEMYiNTSHEiN Is the main engine rotation clockwise or counterclockwise from flywheel end for ahead command ?
@najinkunnath6009
Clockwise for this engine, 6UEC42LSH-Eco-D3
@@CHiEF_MOEMYiNTSHEiN ok
05:52 wont the oil under the depth gauge be a problem
Good Question !
We have stopped main line oil pump and cooled down for a while before entering crankcase and take measurement.
Can assume crankshaft isn’t afloat due to lube oil pressure.
How many total Readings we take on guide and guide shoe ?
Manual says 16 clearances we take you have shown only 4
Depends on maker and model, clearances measuring method and times may differ.
@@CHiEF_MOEMYiNTSHEiN ok
Excellent
Thank you.
