mazfg Posted April 16, 2016 Share Posted April 16, 2016 Well, I've spent the morning with my veyr helpful garage man changing my clutch. Bought a new overdrive mount to fit as the other was like marshmallow. Fitted it, went to drive off and the propshaft was rubbing inside the tunnel.....the new mount is too high. Comparing them both anyway..seems to show that they are a little different in makeup? The new one didn't actually line up with the plate underneath and so I had to initally space is to the gearbox face. Anyway...bottom line is, I had to put the old squidgy one back in because of the rubbing propshaft...Anyone have any ideas if there are different types? As far as I can see there's only one Part no.: 159656 The original looks more like this:This German one from http://www.bastuck.com looks better and slightly different?Cheers Quote Link to comment Share on other sites More sharing options...
John Kipping Posted April 17, 2016 Share Posted April 17, 2016 I wonder if you have the correct diameter propshaft - or possibly some screws into the tunnel are too long.Not really sure why Bastuck would have the reproduced the original mounting rubber with unnecessary holes and welding - a simplified repro part was made some years ago.159656 is backwards compatible with all overdrive units (the holes onto the od unit are 3/8" rather than 1/2" to fit a J type) Quote Link to comment Share on other sites More sharing options...
mazfg Posted October 5, 2016 Author Share Posted October 5, 2016 Just resurrecting this thread as I have both the original mount and the replacement here together for comaprison. As you can see..they are different and the fixing holes to the O/D are definitely different in height but also the mount is offset. Which shows that I'd need some sort of spacers to accommodate this when fixing to the O/D.....? Not sure what's going on here..? As I mentiones, when this was fitted (with spacers), it was too high casuing th propshaft to foul on the top of the tunnel...(Apologies for the last one, it's meant to show height difference but not too clear unless you look very closely 😀 ) Quote Link to comment Share on other sites More sharing options...
JohnD Posted October 5, 2016 Share Posted October 5, 2016 Having had two of the left hand type, modern copies, seperate the rubber from the lower metal mount. I now drill straight through the lower, rubber and upper parts and place two bolts in there. Does't stop separation , but at least limits movement.

Clive Posted October 5, 2016 Share Posted October 5, 2016 I have seen lots of the RH type. All earlier, d type. Even got a NOS years ago.I gave up with the repro type, end welded the OD bit to a NOS GT6 engine mount (that was submerged in water) That seemed rather better!

Pete Lewis Posted October 7, 2016 Share Posted October 7, 2016 The mount with the bracketry attached is not normal ??(my veiw), I wonder why this has been made upone thing that I dreamt of was there are a variety of mounting plates that bridge the chassis rails For 4 cyl, and 6cyl etcjust a thoughtedit just realised you have a viteese with a J type that means nothing is standard So the mountt has to be made to fit No parts diagrams will show that configuartion for a 6clypetepete Quote Link to comment Share on other sites More sharing options...
mazfg Posted October 7, 2016 Author Share Posted October 7, 2016 Sorry Pete the above diagram is misleading. ..I have a D type overdrive. ..the pic was just to show the mount Quote Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 8, 2016 Share Posted October 8, 2016 Ahh ha .. dump that idea then ..Ha ! still dont see what all the plates are for on the big version,, its semmingly been modified to align something ...but what ??Pete Quote Link to comment Share on other sites More sharing options...
mazfg Posted October 8, 2016 Author Share Posted October 8, 2016 Maybe the plate on the chassis it attaches too isn't correct, hence why it's been offset..because the new one will need spacers to marry up to the overdrive as well as holes slightly lower..else it snags on the prop tunnel. Will have a look today at the chassis plate and take some pics of that. Quote Link to comment Share on other sites More sharing options...

RobPearce Posted October 11, 2016 Share Posted October 11, 2016 That looks like a correct plate for a D-type, with the three holes for access to the various plugs on the bottom of the O/D unit.Is your engine mounted normally, or has it been shifted back half an inch?

Jonny-Jimbo Posted October 11, 2016 Share Posted October 11, 2016 Weren't there different length adaptor castings that join the main gearbox case and overdrive case? Quote Link to comment Share on other sites More sharing options...

Engine mounted normally. Standard engine mounts in the front to the turrets.... Quote Link to comment Share on other sites More sharing options...
