perators, nothing shuts down
grader operations like the loss of
engine power. But, before you take
your grader back to the shop,
check its turbocharger for a cou-
pling leak. You might be right back
in business.
If the coupling is misaligned or if
seal rings are missing or damaged,
your grader will lose some turbo
boost and it will seem sluggish.
So eyeball the coupling for a
crooked connection to the muffler.
Look for signs of leakage like car-
bon stains. Eyeball the seal ring to
see if it’s missing, cracked, split or
torn.
130G Grader . . .
If you find any of these problems, tell
your mechanic.
He’ll loosen the muffler-to-turbo con-
nection and align the muffler with the
coupling.
While he does that, he can look at the
seal rings. If they’re damaged, he’ll re-
place them, the packings and the gaskets.
Once everything’s OK, he’ll tighten the
connection and you’re back in business.
