| Post subject: | Pinning engine mounts !!! |
Ok this is another question that has me a touch baffled at the moment. Now I have seen plenty of places where people are pinning the mounts to stiffen them up instead of having full solids. I can understand this as its cheaper easier and you know the mount will definitely fit as per original. BUT it seems that most people are using stainless pins/ bolts or rod in the aluminium mounts !!! now I thought that stainless against aluminium is not a good idea due to corrosion problems. stainless and alloy touching causing a reaction etc ? would it not be better to use steel and then cover any exposed areas with a rubber solution ? or would this be ok to use stainless and cover with a solution ? |

If you're pinning them you can use whatever...because you're not trying to undo a bolt. |

Thanks DoctorC So its not going to cause any corrosion too fast then. I wasn't sure if the stainless against the alloy would cause a anode type reaction and eat away at the alloy pretty fast. I think the alloy used will be of very low grade, as the top mount alloy casting is very poor quality. Although the bottom mounts were made by a different company for OMC so might be better quality alloy ? the rubber part in between the alloy parts is terribly weak and soft. probably ok for a slow pleasure cruiser where the vibration would be more of a pain for passengers. But what you say now makes sense, as its not nuts and bolts. I shall pin a old set of mounts and see how I get on. just got to set up the bench drill now and see what happens. |
