Hi all
Just motored a round trip of around 60 hours and my
yanmar could do with some new front mounts. They were due last season but did not get around to doing them. The
engine is around 12 years old and done approx 1800 hours. They looked quite corroded and flaky so thought replacing would do!
I have purchased the r&d ones and they are actually like for like so all the holes match up and pretty much the same to look at. I know they are not genuine but the
reviews were excellent and they were quite a lot cheaper,
When I removed the old ones I was surprised to see that both the front ones were rated at 200 when normally one side would be 200 and the other side should be 150. The new ones that I have purchased are based on 200 and 150 as per
yanmar specification.
They were mounted and the alignment checked but now when I idle the
engine I get small vibration but when running the engine up the vibration goes away and the engine runs smoother than ever.
I have tried tweaking the adjustment and it seems to improve when I loosen the top nut on the mount so it is not so tight! Is there any tips that anyone can shed.
The height of the engine is the same as before! So no change there
I believe it is something to do with the tightness of the top nut and maybe the way the bottom nut that the engine sits on is also too tight.
Has anyone got any
advice or had similar issues???
Thanks
