Title: Easist way to fit engine
Post by: Seamus on April 13, 2009, 06:38:55 PM

I have the frame back from coating and will have the engine finished in a week or so. Does anyonr have a good method for fitting the engine back into the frame?
Thought about laying the engine on its side and laying the frame over it. (Nothing attached to frame at the moment, so spomething like this could work.
Hopefully someone with experience could advise.

Cheers

Seamus

That's the way CMM's Rod Gibson did it with his resto as I recall, works well, easyer than lifting a full engine into a chasis

I've tried both ways, engine on floor and lower frame and engine into upright frame, got the engine lodged in the frame both ways.

For me the easiest method was to wrap strips of an old towel to the bits of the frame most likly to get damaged and tie them up with zip ties, get a friend to help me lift the engine in and resting on the lower tubes (protected by the towels).

I then used a car sissor jack to raise the engine at the back and fitted the mounting bolt then do the same for the front.

Be careful as it's dead easy to get the engine stuck at an angle.

Thanks for the replies.
One of my thoughts was to use some pipe insulation on the frame tubes prior to installing the engine. (like the towels idea).
I have not got any experience of this and I appreciate the views of folk that have done this job

Thanks Again

I fully agree that it is a pig of a job however you do it, but if you have a bare frame, I would get the engine on it's side and lower the frame over it. A 20 odd pound frame is easier to handle than a 170 pound engine.

Agree with all of the above, adding that whichever way you do the job, two sets of hands always makes it a whole lot easier.

I used strips of lino - that floor covering stuff - and zip ties bought in bulk from ScrewFix instead of towels.  Lino's cheap, easy to cut to size, doesn't snag and is tough enough not to tear if it gets clipped by the engine casing.  Cardboard works pretty well, too.

If you've got a bare frame, drop it over the engine.  But again, two sets of hands.

Thanks again people.
There was always going to be two pairs of hands as I needed help to get the motor out. I will use some of the above suggestions and see which method works for me.
Appreciate the input
