Safe Polyurethane re: Bogie Wheels

Bruce,

Thank you for your wise words of advice regarding polyurethane. I had considered doing a "pour" but I have now opted for purchasing a 20" OD by 15" ID by 8" wide polyurethane forklift tire and I will have a local machine shop machine the OD/ID and slit it to width to fit on the bogie rim. Much safer! I hope to have the shop start on it next week.
I will post pictures and an update on MLU under a new thread.
Many regards, Richard.

Rich I would be interested to see how successful it is using off the shelf forklift tyres and modifying them to fit

Cheers

All steel bogie wheels

Here is an image of the aft mounted single bogie without rubber, but all steel. The pair are mounted on a Mk. I*.

polyurethane

Well, I poured one wheel today with poly and it turned out OK. I got a small bubble at the filler hole,but nothing to worry about. I will pour the 2nd one tomorrow.Should be able to do a nicer job the 2nd time around. :) The cost is about $170 per wheel. Now to see how long they last.....

I have a pair of them on one of my carriers and they are the worst thing possible to have. The track guides are worn out to the point where I don't think they would last much longer, without rubber wheels being put on in place of the steel ones.

Rubber is measured in SHORE ratings. Standard O rings are 70 Shore and harder ones are 90 shore. 60 shore would be very soft, too soft in my opinion! Would 90 shore be too hard tho and cause premature breakup? :confused Im a hydraulics engineer so I only understand seals...!!! :thup2:

Rubber Rating

Over here in Oz the rubber rating is in Duros. My wheels use rubber rated at 75 Duros which is more than adequate fir Carrier wheels.
