OZM29C Posted November 16 Share Posted November 16 @Patrick Tipton@M29C3284 Patrick, This topic is reason enough to start a new thread so we don't hijack @darth_kitten's thread. I initially set my weasel up with one thick and one thin shim per bogey arm, similar to what M29C3284 had installed on his weasel. I found that after some testing (Both land and water) that the bogey wheels were pushing the track guides to the outside which in turn was hammering the track guide tops into the track sprocket guide plates. I then fitted 10mm (Approx 3/8"Inch), see attached photo, shims to the bogey arms and this had the reverse effect by pushing the track/guides back to the inside and chaffing the outer side of the track guides. So in my case the sweet spot lies somewhere in between. All of the adjustments were made with the suspension unloaded (weasel lifted off the ground) however the next adjustment I make will be with the suspension under load. Unfortunately I could find little information on this subject in the TM's but hopefully Patrick you may have access to more documentation. I did find a photo in the attached weasel brochure that shows some special tooling/jigs to set the suspension up in the factory. Interesting subject. 3 Quote Link to comment Share on other sites More sharing options...
Patrick Tipton Posted November 16 Share Posted November 16 Great idea John. There is a lot of lost "art" in getting these machines to operate correctly. Hopefully we can figure this piece out and get it documented so the process is easier for the next guy. My LAR tracks on the unrestored M29 are running pretty well. I would say the bogies are perpendicular under load (basic empty weight of Weasel without passengers/cargo). I will put it on my list to remove one of them and measure the thickness of the shims.

Regards, Patrick @Patrick Tipton Bizarre as it might sound, I am going to use a small spirit level and then lay against the outside of the bogey wheels to ensure that the bogey wheels are correctly orientated vertically after I make my shim adjustments. BTW I too am running the LAR tracks. 1 Quote Link to comment Share on other sites More sharing options...
M29C3284 Posted November 18 Share Posted November 18 @OZM29CAre all the suspension bushings and bolts on your weasel in as new condition? Just wondering if having too much play/wear in the support arm bolts and bushings would cause the angle of the bogie wheels to shift regardless of how many shims are installed. I noticed on mine, when I started installing the yokes and support arms, that there was a terrible amount of play in the whole assembly. So right now I'm making new bolts and bushings for the ones that are not avaliable. 2 Quote Link to comment Share on other sites More sharing options...
OZM29C Posted November 18 Author Share Posted November 18 @M29C3284Thanks for your valuable suggestion. I can confidently say that all suspension bolts and bushings were replaced with NOS parts. I had to replace them all due to severe wear from lack of lubrication. That’s the Achilles heel of a weasel, the constant need to keep the suspension regularly greased. 4 Quote Link to comment Share on other sites More sharing options...
DonM Posted Tuesday at 02:02 AM Share Posted Tuesday at 02:02 AM We have started removal of the bogies and suspension arms from our hull and one side is done. We found that the suspension arms were shimmed differently for each bogey set. Going from forward to aft, the shims were 1 thick + 1 thin for the first set, 1 thin for the second and third sets, and 1 thick + 1 thin for the rearmost set.

DonM Posted 14 hours ago Share Posted 14 hours ago Correction for my previous post........there is 1 thick and 1 thin shim on each of the 4 support arm mounts. Quote Link to comment Share on other sites More sharing options...
