Well, we have discovered low compression on 3 cylinders... about 50 psi and think it is a ring/cyl problem. The main symptom is a rough idle. 87,000 original miles
We are making room in the barn to park it and would like the membership's input on how to remove the engine.
1) The side door is only wide enough to maybe move the block thru.
2) The front opening is too small.
3) Remove the entire front fiberglass piece!
4) Remove the engine from the bottom
5) Remove one of the front windscreens
My soon to be ex-husband and I have looked at these chassis and have come to the conclusion that there is no way to get them out without taking the fiberglass front off. I am not sure but you might be able to remove the heads and then take it out from the bottom if you remove the exhaust. Either way it is going to be a pain. Do a leakdown test to make sure wether you need to just remove the heads or if the compression loss is coming out of the bottom end. Compression tests only tell you that you have loss not where it is coming from. There is no point in removing the engine if you have a burnt valve.
Thanks for your reply.
I will post the results of the comp check in feb.
My two cents worth here. If you run your normal comp check and then squirt some motor oil in the spark plug hole then run it again. If the comp comes up....rings ect. If no diff.... valves ect. The oil will seal the rings. If you have valve/top end trouble oil makes no diff. "see Martys advice" leak down test.
As far as engine removal, Strip it to a short block. And out into the coach and out the entry door. I work on a lot of boats and face simular issues. Not being able to see your setup/challenge. I would guess. 1. Remove front seats and block up a cross bar to hoist short block up out of the hole. 2. Lay a long 2x12 or so from front of engine to door your going out. Lay out 3 or 4 pieces of pipe cross ways and a piece of plywood on top of pipe. 3. Lower engine onto plywood and roll on pipe to your door. As the pipe comes out just add to other end. I have moved some very big heavy stuff this way. 4. Reach thru the door with a cherry picker and take out short block. Hope this helps, Fair winds and good luck. Tony and Joy
The folks at Tiffin replied and said they pull the heads first and then remove the engine through the Driver Door with a frame.
This sounds good to me.
Ok. great to see "step-by-step" pictures of the "experience" when you do it.
(grumble, grumble... they should make the folks who design things like this do the work. No fixin stupid)
Do a -leak down test- on the engine, you may find that it only needs a valve job.
Sorry for resurrecting an old thread, but I'm looking at an '84 Allegro this weekend. It's either a 27 or a 30 - can't tell from the pics. It has 2 ACs which makes me think it's a 30 but I don't know.
In any event, I can get this thing for next to nothing. Owner (which is the company that towed it when the engine failed) claims everything works - both ACs, fridge, all gas appliances. Generator "needs carb work". Looking at the pics, it seems someone set out to go camping and experienced an unfortunate engine failure. It looks really well maintained.
The 454 threw a rod and needs to come out. I've taken engines out of lots of things. But how do I get it out of this one. Is there a follow-up to this story? How hard is it to remove the fiberglass nose? Should I take the short block out the driver's door?
Any advice would be appreciated.
After reading the following post, I need to add my 2 1/2 cents. Its a pain, but like the recommendation below says,, remove the heads, Acc.,(alt,p.s. pump, a/c unit etc) from the block. Have some plywood along the path to the door, moving out of the way,anything that will hinder the moving process.
I talked to good friend of mine and he took the nose off and still ended up going thru the cabin to remove the engine.
So, taking off the nose is basically adding MORE time to the swap. He said, 2 people can manuver the block to the side door and then hooking up the cherry picker and finishing the removal,, the reverse the process,,, sliding in a short block (block with heads removed) then installing and finishing up with the heads installed.
