Help Identifying 3QM30 motor mounts

Postby warmrain » Tue Nov 03, 2009 4:24 pm

I'm looking to carry a spare motor mount and I am having trouble identifying with one to purchase (and the dealer is not very helpful). The motor mounts are supposed to have an indentifying number cast into the side of the rubber (50, 75 or 100). I can't find any numbers on mine...

I am assuming that this is weight and that it is in kilos, so that is a clue for me, but I am not sure which to order or even if the ones in front are the same as the rear ones.

Can anyone offer assistance?!

Thanks, Cars

I did change the four of them this last summer. My old mounts (I think they were originals) had a 150 on the rubber part and it took a lot of research to finally find the part number. I sent a picture to Torresen (they are great) and they came up with the right number. Their price was also great compare to what I could get in Montréal.

The good thing is that the old ones had a 1/2" stud while the new ones are 5/8" and in fact the hole in my motor brackets is actually 5/8". This makes things a little tighter to adjust but they do fit very well. The bigger stud was good news for me because two of my old mounts had a broken stud!

Thanks Ricardo, We just decided to carry a spare. We are 23 years old with only 1300 hours but you never really know when one might let loose, esp the one under the exhaust that has had some salt water spilled on it when the exhaust elbow started to corrode through.

Mine appear to have 5/8" studs on them...

Best, Cars

You'd be far better looking at the mounts made by Polyflex not only are they better made, they do not rust & are a lot cheaper than genuine Yanmar. They have a distributor in the USA

Try: www.polyflex.com.au
