Imp Restoration

anthonydoldd · Nov 29, 2012

I am starting a new link to try to get the information a little more organized. This Feb. I bought a 1404 from the electrical coop I work for. It was pretty straight but ran really poorly and was rattling. Bought the imp for 800.00 it came with removable rear cab and was overall pretty straight.

Snowtrac Nome · Nov 29, 2012

i'd have given 800 for that one than tried to shoe horn a little 2300 cc pinto motor or even a 2.9 efi bronco motor

I took it home and pulled the engine out the next day. The oil pump driveshaft was sheared off. I started talking to our shop mechanic and he told me that one of our lineman had flooded it on a 0 degree day they needed if for some winter storm work. He finally got it firing and mashed it to the floor. Obviously thick oil and high rpms the shaft sheared. They loaded it on the trailer ignoring the oil press guage and when they got where they were going it was rattling pretty badly. The rod and main bearings were sharp as razors when we tore it down and the 1 + 2 cylinders were pretty scored.

anthonydoldd · Nov 29, 2012

At this point the quick fix was out so I decided to redo the whole thing. Pulled the cab drilled all of the rivets and stripped it all of the way down. Decided to paint the frame and clean and paint everything else.

quite possibly the worst job in the world drilling all of those rivets! :ermm:

anthonydoldd · Nov 29, 2012

Parts were hard to come by and real expensive so we did some measuring and chose the 2.3 out of a little mustang to be our new powerplant. The efi is relatively simple, and its compact enough. We found and Automatic trans for it went with the ford A4LD which would have been the factory trans for the engine in the mustang.

When I got the engine here I cut the transaxle shifter out and one brace and gave the engine a test fit.

Every thing cleared the cowl but it was obvious that the factory cowl would not work again...

anthonydoldd · Nov 29, 2012

Now that we knew we had some clearance we cut out the factory mounts and made some of out own. The engine sits nice and low in the frame and has good clearance all around. It took a little while but we got it all centered up and welded in the new mounts.

anthonydoldd · Nov 29, 2012

Now that the mounts were in I attempted to sand blast the fram with a small shop sand blaster. :glare:

Waste of time I will tell you that old undercoating is a real nasty concauction. I finally just called a comercial blaster and for 130 bucks and an hr of dinking around the frame was ready to go.

At which point I realized that I had forgotten to make a trans mount so we welded one in.

Its a pretty heavy box steel, our thinking is that if we ever do run up on a rock it should protect the pan pretty well.

anthonydoldd · Nov 29, 2012

I decided to make it a full cab so we welded some gussets made of 1 x 2" box steel to the bed. They line up with the angle of the engine compartment in the front so we shouldnt have any clearance issues.

We added four to each side but I cant seem to find a pic that shows them all..

anthonydoldd · Nov 29, 2012

We did a final mock up of engine trans and made sure they would line up nicely with the rear transaxle. Everything is pretty much dead on with almost no angle through the driveshaft!

Ok so now we are ready to paint the frame. I ordered POR-15 chassis black. Its not the cheapest but its suppose to be very durable and its really pretty easy to use. It is a little thick though!

We got a few runs in it but it has a nice coat on it now and its all the same color so it looks a lot better!

anthonydoldd · Nov 29, 2012

While all of this is going on I was also getting the engine ready. Rolled mains and rod bearings in. The cylinders looked great but the engine was only suppose to have about 40,000 on it so no real suprise. The bearings looked good but we figured we could get to it easy enough so why not. Cleaned everything up really well and painted the engine.

Snowtrac Nome · Nov 29, 2012

i knew i'd seen a 2.3 in an imp somewhere before good work you should have lots of fun when it's done

anthonydoldd · Nov 29, 2012

Thanks dds

Its been a fun project so far. The auto will be nice and the range and less effect on power at elevation will be great. I think we might wide track it but I want to see how it goes on original tracks first. I am a little concerned that its top speed will be a little hairy. Its an O/D trans and all but thats where the oc-4 will be nice.

Snowtrac Nome · Nov 29, 2012

well if you wide track it maybe a good time to upgrade to torsion axles and lift it abit

anthonydoldd · Nov 29, 2012

I agree I want to do a torsion axle suspension... I have been thinking about a couple of different ways of doing it. I want to wait a year though and see how the flotation is with the 24" tracks. I am sure I will wide track it but I dont want to get so wide that it starts burning up my hp without a large improvement in floatation.

anthonydoldd · Nov 29, 2012

So now we have the engine and trans back in and all bolted up and am really happy with the way everything is going together.

anthonydoldd · Nov 29, 2012

My plan is to polish the aluminum on the tunnel sides and bottom. I dont want to have the paint start coming off due to being drug through snow or a tree branch peeling my paint. I scraped all of the undercoating off the panels which was also a bit of a chore.

I will polish them right before I reattach them. I am planning to cut new pieces for the sides up in the front. The old ones were pretty beat up so i am thinking I will use some diamond plate.

anthonydoldd · Nov 29, 2012

I thought I was going to have to relocate my radiator but after we got everything in and mounted I realized that if I mount my radiator on the front side of the supports I have plenty of room. So I did that and then mounted the shroud on the front of the radiator. I bought an electric fan that will work as either a pull type or a push type (can reverse the polarity to change the direction of rotation) and mounted it up.

I took these pics before I mounted the shroud on the front side. The last pic is before I cleaned and pressure tested the radiator. Top 2 are after the repaint.

AAUTOFAB1 · Nov 29, 2012

sweet ! i would love a IMP to cat around in.i get to drive a Tucker every winter,but IMP's seem better for cruzeing the trails.

anthonydoldd · Nov 29, 2012

Ive ridden in a couple of tuckers and really liked the ride. I have never riden in an imp but hear the can be a little rough. The thing I like about the imp is that they are a little smaller and seems to me like they might be a little better in wooded areas due to their size. Im looking forward to getting it out though I wont likely be done in time for snow this year. :doh:

anthonydoldd · Nov 29, 2012

I am looking for some input on a driveshaft brake. We have to build a new shaft anyway so I was thinking about adding a rotor to the shaft and mounting a hydraulic caliper for a parking brake. Please let me know your thoughts...

In the mean time I rebuilt the brake master cylinders this cat had some crappy carpet for floor mats, problem was that the carpet was damp for some time and kept alot of moisture around the master cylinders. The master cylinders were pretty rusty inside. I honed them out and got a Napa kit. Luckily i saw BD PEEKS post on building his brakes so it was no problem coming up with a part number.

CRockett · Dec 24, 2012

Have you gotten any further on this project and if so can you update with more pics and info.

anthonydoldd · Dec 26, 2012

A few small things. I haven't been around much and will be doing a lot of work on it in jan. I will post pics then.. I have ordered and gathered up most of the parts I need and will likely have it together with the original rear cab next month.

anthonydoldd · Dec 29, 2012

Linkage for original ford shifter was going to be a lot of extra work so I ordered a cable shifter. I went with a B&M rachet shifter. Should be a
good solution.

Also ordered the seats, going to go with a race style bucket..

Nikson · Dec 31, 2012

Cool... moving along...

0.02cents on the seats...

I've been regretting a bit on going with larger bucket seats vs "farm style" out of a lawnmower or a tractor, since they just take up too much useful space...

and cat does not really need to have all that Cadi comfort...

anthonydoldd · Jan 4, 2013

Nikson,

I thought about that too and agree. The dog house I will have to build will make that decision for me. I ordered one of the plastic race buckets also that have a removable slip cover. If the big ones are cramped I will use these. I will have the terminal blocks and everything mounted under the counsel and the dog house and the computers and relays will be mounted either behind the seat or under it. We are wiring with enough slack to accomodate both.

Well, only time will show whats better/worse...

Little comfort never hurt anyone I guess...

anthonydoldd · Feb 17, 2013

Well I made a trip home and we got some of the wiring done... We got all of the wiring figured out and now are waiting on the fuse panels and relays that we ordered. I thought I would post a couple of the pictures of the progress we made. I got a new job close to home so I will be working on the machine a lot more now!! :brows:

Here is the harness we started with

anthonydoldd · Feb 17, 2013

We Stripped it all down and are making one harness out of two. There is not much left after we weeded out all of the unnecessary wires.

anthonydoldd · Feb 17, 2013

Lots of Notes!!!

I think I still see diagrams when I close my eyes!!! This could possibly make you go blind after a while.... Or at least crazy :w00t2:

anthonydoldd · Feb 17, 2013

Boy it can be a lot of work to get pictures on this website!!! sorry no more big pics they wont post...

Got the end complete the harness comes out in two place because one will go to the rack of relays under the drivers seat and the other will go to the engine harness and dash..

Just beginning to make two harnesses from one. we are staggering the cuts and then shrink tube and soldering the two harnesses together..

Engine control harness nearly complete.

This is the slowest part of the project with out a question. Progress is slow but sure!! We also have wired the harness for the transmission and have all of the dash instrumention leads ready so we are moving along.
