Experimental chain tensioners

The goal with these tensioners was first to have tensioners that did not have to be re-adjusted every time I rode the Hustler, and to eliminate a lot of driveline shock created by a static chain tensioner.

In the picture where the tensioner is already installed, we welded additional cross bracing due to the factory welds coming loose, and attached the tensioner to the square tubing that we welded in. This tensioner will push up on the chain by simply loosening the bolts from the top. We welded nuts on the bottom of the tubing so that a backup will not be needed.

The tensioner that is just sitting on the trailer, will be bolted to the frame in back and will pull up on the chain by tightening the bolts, again, no back-up will be necessary.

I am pretty excited about all the changes I have made this time around....red clutch spring, correct belt tension, chain tensioners, and re-sealed T-20. A little cleaning up and painting on the frame, and I am ready to re-assemble.

BTW, I HATE the keyed axles on the center drive axle where there are three sprockets. They tend to get stuck, and I broke my hand two weeks ago by accidentally hitting it with a hammer when beating on them (It's ok to make fun of me, everybody else has!). I did find that on the axles with only one sprocket it is very easy to remove the outer flange bolts, all set-screws, pull out the axle until the sprocket is close to the frame, and use an air hammer through the outer bearing hole to remove sprocket!

Here's the pics..

bone a little antiseze goes a long way

Hey Rdr,

Great minds think alike! You and Meinfeld that is...

Me and Meinfeld talked about this very thing...we were doing an experiment, he used anti-seize, and I used dry lube (on the recommendations of a machinist). I just got both of my center axles out again last night and I will say it was much easier this time.

But, in retrospect, I think my difficulty last time was due to my frame cross-support failure+premature bearing failure on one side. The center axle on that side appeared chattered on the undersurface of the sprockets....

I am gearing my Hustler down 30% to compensate for the bigger tires....should be interesting. Me and Mudbug are gonna thrash it next weekend. I went from a 30 tooth center drive sprocket to a 40 tooth...

what ever i put togather has antiseze on it if it has to come back apart .i learned that from my flats boat in salt water . jack plat bolts do not like to come out after salt water and crossion . i put the axels in my max II in with them when i changed bearings went bad i beat them and my self to death trying to get them off befor i antisezed them not it takes a bout.30 min to pull the axels out works great robbie .

max antisezes them now from the factory , robbie .

Hey Robbie,

I am definitely going to anti-seize them this time. But I have decided that the best fix would be to get Whipper to make up some splined center axles and sprockets for the Hustler, I could even upgrade from 1 3/16" to 1.25". I will leave the keyed axles front and rear, as they are easy to get off.

JPSwift was telling me that the splined axles are much easier to remove?? Has that been your experience??

Splined with snap rings are...a snap!

Boncrshr- I can't wait to see how that Hustler performs with the new gearing.Make sure you get lot's of video when you go out with mudbug. The Vampires seem to be a perfect fit for your machine, now you just have to get everything in order to get the best use out of those tires and make everything work in harmony.

mine are but there antiseized to death . onily time i have had problems was when the end was bulges out . doin't know how tha happon. love my splined axels

Hey rdr,

Thanks..and you are exactly right...it is definitely a trial and error process to get things exactly how you want them! The bigger tires really sapped some power, and I may have been over geared to begin with because there were times with the 22" tires that I smoked the belt. So I am kinda curious too...I plan to drive it like I rented it this weekend!

My main goal for this weekend is I want to find a nasty mud pit and make a slow, deliberate pass...then make a Meinfeld full throttle pass and see what happens with the lower gearing. Mudbug thinks I'm gonna get stuck...but hey, he has a winch!

Make sure its a hardened sprocket , or it will wear out a lot sooner. I,m sure thats why it was so cheap
