My JD400 has a new sibling a 1993 455 with 1000 hrs, 50" blower, 48" deck, 50" 450 tiller, Hard cab, 3pt, 540 pto, quick hitch and around 10 other attachments.
The first this I noticed is the 93 model year only came with 16 inch front tires and 23 inch rear tires. When you have the 400 and 455 next to each other is there a noticeable difference between the two in tires sizes.
The first thing I want to do is change to 18x8.5-8 wheels on 5 bolt hubs in the front and 26x12-12 HDAP or lugs in the rear.
I was looking through the post but wasn’t able to find the answer to my upgrades.
I know you have the answer and look forward to the responses, so here goes:
1. With a 48 inch deck (have the optional power flow) will these larger tires work. That is will there be enough clearance between the deck and tires in both the raised and lowered positions.
2. Will these tires clear the fenders.
3. How would you prevent the hubs from sliding inwards on the existing spindle in order to preload the roller bearings. If you do this then the seal on the back side will press up against the stopper and rub away on it. I thought about a small sleeve or shim over the spindle that could be used to shoulder the inner bearing against, but then the sleeve would spin since the seal was wrapped tight around it.
Looking forward to the solutions.
Thanks, Robert
