I still can't get a straight answer on what he charges on the carb cleaning - let me know what carb, whether he disassembles/assembles & puts in the carb kit, etc. and I'll get a price from him.

Sam had to replace the sections of fuel line under the RV that had bends. The rest of the fuel line looks good, but it looks like the pump for the rear tank is leaking through the body (or under the hose clamps, but it's hard to tell right now).

Changed the oil and filter today and filled up the tires. Sam took it down and filled up the fuel tanks and put Sta-bil in the fuel.

I'd put seafoam in the crankcase a few months ago so it'd get run through and clean up some sludge. Two months of running in the driveway, then driving back and forth to the gas station, then change it while still warm. Came out pretty black, but not chunky. Haven't had the lifter tick on the driver's side since I added the seafoam.

Next is motor mounts, oil pan gaskets and oil filter mount gasket. We'll do that the next time we change the oil. I need to change the oil in the generator, as well.

Spring is coming, Lee Ann!  Time to coerce Sam into a garage for the tool box and place to work on smaller jobs.

I'm working on it Wink

Actually, we're talking about getting one of the bigger carport things, putting down pavers as the floor and, eventually, little by little, adding sheet metal to be sides and back.

Did some work on her tonight 'cause we wanted to take her for a (close) trip this weekend to a boat race - we wouldn't be racing, just spectating - plugs, pcv, air filter. I have wires, cap and rotor, donut gasket and valve cover gaskets as well.

Started her up. She idles real smooth now. Until you touch the brakes, that is....brake booster's bad. It is original (still has undercoating on it, sorta), but still. Also glad we didn't replace the passenger side donut gasket 'cause it's not leaking - the driver's side is (for the first time).

We're not going anywhere with a bad booster, which sucks. Now I've gotta find one...

Boosters for these are slightly harder than that to find Wink

I'll try my local parts house first, as my boss' brother works there and I can get his discount (ie for cost), plus they actually have parts books and know how to use them  Grin

If they don't have or can't find it, www.alrettatruckparts.com is next. They have brake stuff for our ancient rigs and Geoff, the owner, is quite knowledgeable on these systems (he posts on MH forums a lot).

1973 M300 w/Disc Brakes w/ Vacuum Booster -- CarQuest #50-9261

Might not be right ... I don't see a listing for Bendix Master-Vac and all the listing for booster that include slave cylinders have a footnote.

Get the (casting?) number off the booster and I'll try a cross reference.

It's an RM300, not M300.

We'll have to pull it for that - it is original, with undercoating and a ton of rust....

Catalog also lists the R series chassis ... same P/N for the R300.  (My RM350 is listed as a R400 and I back checked the caliper numbers to partially verify catalog's accuracy.)

Catalog's numerical listing shows that P/N fitting Dodge "M,R300" from 1972 through 1977.

Casting number will be necessary to make reasonably sure that's the right P/N ... I cross referenced my caliper casting number to make sure for my chassis ... and looked up a picture on the company's intranet.  (Catalog showed a single piston caliper for mine but I actually have dual piston calipers that catalog shows for later years ... maybe someone retrofitted the front brakes??)

Booster catalog heading is "M,R300/350/375/400/450/500/550/600/650" and covers model years 1970 through 1978.

Cool -thanks Wink

I have the Dodge p/n with me. We'll look up both to be sure.

The Carquest # is obsolete - that's the one that comes with the master cylinder, which apparently they don't do any more.

However, both it and the Dodge p/n both crossed to the same booster sans master cylinder. I'll have it Monday for $110....and I'll get the p/n then.

Got the booster off (took LOTS of patience and PB Blaster) only to discover the master cylinder is also bad. The seals were leaking fluid everywhere and it got sucked into the booster and killed it.

Just picked up the master cylinder (Bendix) yesterday and we'll install when the weather allows this weekend. It looks really nice and everything matches up, except the new one has 2 bails while the old one has 1.

Sam says he thinks it'd already been replaced once; there's a brake line repair kit spliced in a foot or so back from the master cylinder.

I'd say there is a good chance it's been replaced at least once, possibly more since 1973.
