Over the Holiday break I promised a fellow weasel owner (on this forum or over on the FB weasel group) that I would post some photos of my Wiper Motor rebuild.
Anyway please find the photos below. Cheers John

Here's the VWM booklet for reference. There is a typo on the starter solenoid to regulator wire termination.

I can post a copy of the VWM handbook if needs be. Has all the colour codes and wire gauge sizes.

Just off topic but still relevant to this thread. David Welch on the old weasel forum posted an excellent article on how he adapted a modern in tank electric fuel pump into his weasel fuel tank. I am sure that if you contact David, he would still have the information and photos to share.

My weasel has been laid up too long waiting for the transmission to be repaired. I found our chooks (chickens) had laid some eggs in it😄. Anyway today I wrapped up the transmission repairs so the first task after Xmas will be to replace the transmission and get the weasel mobile.

Ah, good to know! I soaked the screwheads in paint stripper to help unstick them, cleaned, and soaked in wd40 overnight. No go. Used an impact screwdriver and twisted off 4 heads and tore up the slots on the remaining 2. Now that I see what's there, I can punch out the remains and construct new ones on the lathe. I will be pulling it apart, cleaning, oriming, and painting before the glass guy puts in fresh glass. Thanks very much for the pictures! Big help.

@Idaho Jim I will look tomorrow on my work PC as I am sure that I made some drawings on those screws.

@Idaho JimAt the centre of the windscreen frame where it pushes into the hinge frame you will find a small round head screw (photo 1) and on the side frames you will find 6 special special screws (photo 2), three per side. Getting the frame to separate can be a character building task. Good luck.

Great stuff Fred. I think your observation about the center bands being really important is spot on. These tracks need to be very tight to run well. If the center bands aren't doing part of the work, there is a lot of leverage/stress on the center of the grousers. If the grousers have not been too abused, they appear to hold up OK with this stress and the outer bands doing the work...but if the grousers have been weakened by rust....good chance of breaking them.
@Patrick TiptonIf you go to the trouble of replacing the outer bands, then it would be time well spent to replace the inner bands as seen on the Snake River tracks.

That is a great solution John! I have a couple of pretty rough main shafts that have out of spec needle bearing ends.....
@Patrick Tipton Please be aware that this is a compromise repair solution. The end of my transmission main shaft had been machined down to 15.02mm (0.5913"Inches). As you can see in the link, the ID of the collar is 15.00mm (0.5905"Inches). Those dimensions provide a good interference fit to retain the collar on the shaft with a loctite super retaining compound. I measured the collar OD after it had been pressed onto the shaft and it measured 15.03mm (0.5917"Inches). I also measured the end of an MB/GPW Jeep transmission mainshaft as a comparison and came up with 15.11mm (0.595"Inches). That works out to an additional running clearance of 0.083mm (0.003"Inches). For the amount of miles this weasel transmission will do I am more that happy to live with the OD of the repaired shaft being 3 thou undersize. Having said that I took the liberty of fitting a NOS set of pilot rollers and now the pilot roller assembly is the best it will ever be. I will post a road test report.

Following on from my initial launching I had a catastrophic transmission failure which brought a premature end to my weasel activities. After I had removed the transmission to investigate the problem, I found that the bronze bushing I had initially machined and installed between the transmission main drive gear and the main shaft had almost disintegrated. See photo 1 showing the bronze bushing prior to assembly. I had initially fitted the bronze bushing as I discovered that the main shaft had been machined down to 15.02mm on the end and at that time I could not ascertain why??? Anyway after only 16miles of use the bronze bushing had completely worn away which in turn had damaged the brass synchroniser rings and the synchroniser hub not to mention contaminating the oil. The transmission would only shift into 1st and reverse. 2nd and 3rd synchroniser was locked solid. After doing some reverse engineering, I guessed (correctly) that a hardened steel collar had been pressed onto the end of the main shaft to restore the shaft back to spec. After a long wait, the replacement hardened steel shaft collar finally arrived yesterday. I press fitted the new collar onto the end of my transmission main shaft and in turn the collar was retained by Loctite Super bearing mount. Using a set of NOS pilot rollers, I test assembled the pilot roller bearing assembly. Very happy with the repair. Now to get the transmission assembled and back into the weasel. Sounds like a good job for the Christmas break.

To help with the job of resetting the final drive rotation, I would heartedly recommend familiarising yourself with TM-9-1772B that details the inspection, assembly and adjustment procedure for the final drive. Our forum host @Patrick Tiptonwould have a copy of this valuable resource. Keep the posts coming👍

Just off topic, Here is a photo of another reverse drive weasel from my Weasel photo archive. I have no idea who owns the weasel and what the inspiration was to reverse the driving position. Each to their own I guess.

I took the opportunity to fit an access plate to make life easy when draining the final drive. Might be worth considering for the future. Gary Szecy's excellent article on how to remove the final drive is worth a read as well. Be very particular on what grade of SAE 30 oil you use when refilling the final drive. Using the correct grade of SAE 30 makes a big difference on your steering response. I have attached the spec sheet for the oil I used. Take note of the API rating.

Here is another track system that has been adapted to the weasel. Tracks from an M114. Photos below show the system. I have had these photos in my archive for over 20
years so I am not sure who to acknowledge the photos from.

Here is another track to add to this thread. The Consolidated Industries extra heavy duty track. I apologise for the poor scan quality.

@Patrick TiptonWhat a great idea Patrick. Here is what I have on the Ambillary track. I don't quite know if that is the correct spelling. Also I am not an authority on the history of this particular track. The photos below show the track fitted to an EPF weasel that operated in Antarctica. You can see the similarity to the LAR track. Drawing and photos courtesy of Steve M.
