1995 MAX IV Rebuild Thread (Gary's)

[kghills]

The installation of the center support bar on my Max was the turning point in it's existence. It makes it a completely different machine. Passengers are more comfortable, it drives better with a more rigid feel, body sag is eliminated, tire/track clearance is gained. Heck I even use it to sit my butt on when I go to get out. And mine only ties the cage into the front seat. You will have to let us know how it drives when completed. I always wonder how flex plays into handling and performance.

Was wondering the best way to run very low air pressure and not spin the tires.

Thanks

Bead locks



These will weld to Hustler or Max K lock wheels.

In my max 4 conversion I supported the rear of the roll cage with 2 up rights to the frame and the lower tub from a cross bar welded to the seat frame.

What would be the steel thickness on the DIY bead lock plates? Now see you used 3/16". Anyone already have a CAD file?

Shoot me a PM with your email address and I will send you the IGES files. I nest rings to build 8 inch beadlocks inside of them so there is not so much wasted material.

Whipper has finished the axles (look great) and will be shipping shortly. Roll cage is coming along nicely.

My two idler sprockets on the main drives have sloppy bearings and need replacing. What is the best option for new idler sprockets. Just buy new ones from RI?

Thanks

I just ordered a pair from RI at $30 each, and they're heavy steel with replaceable bearings not stamped like the originals. They can be had at some other places a bit cheaper but I just ordered them from RI to be done with it.

[2gnospam]

Will order a complete set to be done with it. Thanks.

For the wheel drive chains running front to back I was considering getting rid of the stock adjustment system (to make a flatter floor) and going with a different system. Does anyone have any experience using a chain adjuster like the
"Floating-Style Self-Adjusting Roller Chain Tensioners"

Never mind Found the old thread talking about them.

Was just starting to work on installing the new axles (from Whipper) and noticed that RI sent me inner bearings for 1 1/4" splined axles that have a two bolt bearing block. It appears from the current photos on the RI site that some splined axle max IV's use the old style, two piece, 4 bolt bearing holders. So thus I am assuming that the MAX IV came with four bolt inner bearing holders on the smooth axles (early), on some splined versions and went (or is going to) a two bolt block. My concern is that the inner frame will not contact the bearing block as well and could result, during use, in bending of the inner frame rails around the bearings. Does any forum members have experience with these two bolt inner bearings?

Thanks, Gary

Gary,

To the best of my knowledge, Recreatives always, and still does use the 4 bolt 2 piece flangettes for the inner bearings on the Max IV. They use the pillow block two bolt style on the Max II......this started in the late 90's I believe, maybe 1998 I'm guessing.

[2gnospam]

Good catch. I now see that on the website for the MAX II. Thanks. Have left them a message.
