Dear friend,
Good day,
I want to ask a question about MAN B&W engine.
Some engineers do not take out telescope pipe, when they overhaul the piston, what you think about it, why should it be taken out?
Thank you in advance!
best regards

Re: telescope pipe
Hi.
I work with a plant of 2 - 7S50MC B&W, Korean-built, engines and the manual states to always hang the telescopic pipe prior to turning the engine with a piston removed. The only reason I can see is to prevent any damage in case the crosshead inadvertantly rotates when the engine is turned. It`s only 4 bolts, so not a big deal anyway, unless you drop the spacer in the sump and have to go look for it!!
Hope this helps.
All the best.

Re: telescope pipe
Hi,
carbob is perfectly correct; if the Telescopic Pipe is left in situ & the engine is turned then there is a possibility that the Crosshead will try to turn & will bend the pipe. In a worse-case scenario this can cause local overheating & crankcase explosion if it is not rectified.
I hope this helps

Re: telescope pipe
true ,telescopic pipe needs to be suspended with piston out...but other way to go about it is by not turning engine post lifting piston...possible cos i hav a done a decab that way
