I am planning to replace the trans mount and fuel filter on my 87 240 with the M47 tranny tomorrow. The car will be on a lift. Can I just support the tranny, unbolt the mount and slip the new one in, or am I in for a PITA job? I've never done this with the trans in the car before. Same thing with the fuel filter. I got a new filter and copper washers. Is this just an R and R operation? Should I be looking out for anything? Thanks.

Thanks for all of the replies. Your help made the job go pretty quickly. The hint about using the impact wrench to loosen the banjo bolts was great! I wouldn't have thought of that, and really needed the extra punch. The trans mount popped right in. The only trouble I had (believe it or not), and kind of embarassing for a veteran shade tree guy, is that I messed up the ignition wires when I swapped out the distributor cap while doing a minor tune up. It shows how great you folks really are. Luckily for me I had my trusty Bently's in the trunk. Thanks again!

Straight forward..both jobs.

Take the motornmount nut off, then teh four Crossmember bolts. Teh rubber grommets on the Crossmember may be Undercoated on so they will stay put, if not, pay attention not to lose them.

GAs filter: sometime they don't want to let go. You will need a wrench thin enough to hold te Hex shape on the filter as you loosen the Banjo bolt.
Teh hard plastic line from teh Fuel Pump tends to move as you tighten on te hnew Filter, you might want to have it less then horizontal with te Pump so when you snug it up it shifts into position. you'll see.
Depressurizing: I never do, Just have pan that you use for oil changes, once you Crack one of teh banjo bolts loose, you will get a very small spritz and then teh Filter will drain.

I recently did my 86's fuel filter and was getting no where at all real fast.

Put the wrenches on and trying not to snap a fuel line tried in vain to break those banjo nuts. I was out there under the car in the heat for 20 minutes or so trying all sorts of ways to get those nuts off that filter. The bulb went on and I plugged in the air compressor and pulled on the impact wrench.

Both banjo nuts came right off with a single pull of the trigger. Had a new little line and copper washers ready. Put the impact awy an used wrenches to snug up the banjo nuts. No leaks when started so its all good. If you have access to an impact I would try that first to get that filter off is the point.

Never seen an M47 up close but if that sucker is rubber make it last longer if you have any oily fluids that could reach it. Take a good brand of electrial tape and give it a couple of good wraps before you install it. The tape will prevent oil from reaching the rubber. That will extend the life of your part, have it on both motor mounts for going on two years. Tape is still in place and the rubber is still dry. Cheap way to extent your mount life IMOH.

Good Luck,

Paul

I haven't done an M47, but have done fuel filters. Be careful not to tweak the small fuel line with the banjo bolt. I don't remember where it goes to, the accumulator (?). Anyway, handle all that stuff with care, and has been previously posted, check for leaks. Perhaps a pair of safety glasses might be in order as well. I've heard of disconnecting the fuse that runs the fuel pump, then starting the car, and that way you don't have fuel pressure issues when you open the line. Just a thought.

"I've heard of disconnecting the fuse that runs the fuel pump, then starting the car, and that way you don't have fuel pressure issues when you open the line. Just a thought."

Please don't pass that myth around. It doesn't work. Think about it: How will you start the car with no fuel pump?

There's no fuse you can pull without stopping the engine and leaving residual pressure in the lines. Just loosen a fitting and wrap with a rag to catch the small amount of fuel expelled.

Well, I guess what I've heard has been incorrect. I usually disconnect the battery and break out a couple of shop rags around the fuel fittings when I change filters out, so I won't propogate that myth further. Thanks for the correction.

Have never done tranny mounts but have done fuel filters. Filter has a direction of flow so look for the arrow. Catch about 1/2 cup of fuel when you loosen the lines. Don't tighten fittings more than needed to get a tight fit. Use two wrenches, one on the filter and one on the fitting. I use some plumbers grease sparingly on the threads. Start car and watch for leaks, tighten if needed.
