New AC Compressor Belts

Posting a photo of the 2 new belts I installed. No more slipping and squealing, not even when wet. It blows colder air but still need the rear AC for the really hot days.


Thinking of saving up for 2 new systems that use a air channel that runs the length of the bus below the rear of the condensers. Either that or get newer versions of what I already have.

Brakes serviced on all 4 corners

Here I am, back at Alignment Right to get the bus brakes serviced. I have about 30 to 40 percent shoe life left on the front. The rear is a mystery as the hub needs to come off before the drum. Axle seal is leaking on the right rear so those will be replaced as well.


Updates to follow as I get them.

Rear brakes

A few pictures of the rear bus brake shoes and drums. Looks like the shoes are all due for replacement. New rear hub seals as well. Front hubs are dry, no signs of leaking.

A quick note. When replacing hub seals, always remember to seat the hub completely before putting on the preload and lock nuts.

My trip home with new brake shoes almost ended in disaster. I was able to get the bus on the shoulder without swapping paint with another vehicle. I called the shop and they sent out a mechanic who checked the hubs. One was fine the other one had not been put on all the way so the bearings were trashed. He offered me a ride home while the shop dispatched a tow truck to bring my bus back to their shop to fix it tomorrow. I will give an update when I have more information.

Good Morning you fine folks! I have updated news.

I got a call from Alignment Right regarding damage done. The outer bearing was trashed. The spindle got so hot it bent. Looking at a couple options. #1 is have a axle surgeon cut off bad spindle and weld on new/good one. #2 is find replacement axle housing and swap everything over which could lead to more problems as the original one is disassembled AND the used one could also have issues. So, I'm going to leave it in the capable hands of the shop.

Time frame of all this has extended out to next week thursday / friday for completion.
Problem is, I will have a renewed MT643 from LKQ to pick up in a few days. I was planning on using the bus for that but it will likely still be in the shop.

I, for one, and very glad you had a shop doing the work. They will be on the hook for a whole lot more than y'all originally bargained for. It does sound like they have a handle on it though.

Comfort Bus is back home

This morning I was picked up and taken to Alignment Right to retrieve the bus. They explained they even disassembled the passenger side rear hub to make sure it had plenty of lube. The axle surgeon did a great job replacing the driver's side spindle.



First trip was to pick up the MT643 from Santex in San Antonio. I delivered it to Alignment Right to store until the end of the month. I have no forklift at my house and the transmission was blocking access to the wheelchair lift. All I have left to buy is the transmission fluid, Deliver that, the flex plate, shorter flywheel bolts and a new rear main seal AND a week later. . . I go pick up the bus again.



Picture of the transmission in the bus still in it's crate.

oh cool!! you are doing the 643 swap!.. I did this in my DTA360. as most here know.. and Ive been driving it and enjoying it greatly..



the ONE piece im missing that you shoul;d have checked,, is whether the new trans has a speedometer gear or a tone ring.. many of the navistar ReNewed units apparently come with speedo gears.. and 1990 and newer Busses use electronic gauge clusters and therefore need a tone ring..



the tone ring can be retrieved from an AT545.. but as im finding out it can be difficult.. ReNewed has you make a bearing puller of sorts by grinding down some bolts and yanking the tailshaft bearing.. then the tone ring is supposed to slide out..



before that new trans goes up in the bus, pull off the plug for the speedometer in the tailshaft and verify it has a tone ring .. if its got a gear, it will need swapped.
