 |

Gidday,
I have just reamed out the undercarriage frame tubes that support the welded engine mounts attachments. I'm not convinced this is a good mod, at all. If the premise is to stop flexing of the attachment frame top tubes, I see the load now being focused on an area of circumferential stress, created by the end of the reamed tube and the closely proximated vertical bolt that holds the frame into the tunnel. The metal tubular inserts apply all the load on their ends, which is where this transition of internal diameters occurs, right up agains the bolt attachment. I am lucky as I have not yet installed the bolts. If I had, I would be very concerned. I personally reckon for anyone who hasn't done this mod to extend the inserts the entire length, and then drill through both tube and insert for attachment. This will obviously mean reaming out the entire length too, which can be easily done by welding an extension on the reamer. So, in anticipation of "doing it my way", I am interested in advice on what type of metal the insert would be please, for ordering purposes. For those wanting to consider this option, the longer inserts require 2 x 200 mm long x 16.5 mm dia x 2 mm wall thickness. In anticipation.
