meadowfield 2,570 #1 Posted December 7, 2023 (edited) Hi all, I know hoods change, front axles goes cast and trans goes to 2 piece... (probably more things) a few questions if someone can help? Does the frame stay the same from RJ-58 to Suburban 400 - whats the wheelbase? Frame changes on 551 to accommodate the 2 piece trans, does wheelbase stay the same? planning another project that I may or may not finish reminder of things I have finished: http://wheel-horse.co.uk/images/C4/c4_a.jpg http://www.wheel-horse.co.uk/images/Bendy/bendy1.jpg no promises though!

wallfish 17,000 #3 Posted December 8, 2023 I believe all the wheel base lengths are the same and if not they are all very close 2 Share this post Link to post Share on other sites

clueless 2,993 #5 Posted January 11 (edited) I can get a photo of my 400 burb frame without the trans attached, but it will be sometime tomorrow (Thursday) before I can post it. Edited January 11 by clueless Share this post Link to post Share on other sites

oliver2-44 9,755 #8 Posted January 13 I made a new transmission attachment plate fro my 551 frame based on this drawing I found on Red Square. I made one change which was to make the 2.5" bottom angle dimension 2.75" and the top of that angle have a .250 flat section. If I had to do over I would make it 3" with a .500 flat at the top The original design did not have bushing on the clutch rod, but I'm adding them to compensate for wear on the clutch rod at the narrow angle side area. With the original dimension of 2.5" the (unshown) hole for the clutch idler rod is very close to the edge. I will get a dimension on the clutch rod hole in the next day or so. The back plate is 1/4" and the sides are 1/8" The original frame design did not have these bushing on the clutch rod. I'm adding them to compensate for a worn area on the clutch rod where it went through the thin frame side angle 7 Share this post Link to post Share on other sites

meadowfield 2,570 #14 Posted January 23 (edited) have you any side on pictures of each side? - sorry to keep asking.... this is where I’m at Edited January 23 by meadowfield 2 1 Share this post Link to post Share on other sites
wallfish 17,000 #15 Posted January 23 2 hours ago, meadowfield said: perfect! I didn't know there was a plate too! There were 2 different styles of frames they made. You don't need to add that plate in the front if you add the sides like oliver posted in his pics. I was just trying to show you the clutch bar as it's the same place for both syles. 2 Share this post Link to post Share on other sites
