Default Bombardier Bombi Restoration

I recently purchased a starter through Boggie at MN Outdoors (thank you!) and after looking at how I was going to replace it......made the decision to start on a full refurbishment (will need to pull the engine). I finished the SW-48 last year and figured why not.....it’s a journey worth doing again!

Hi Bob
There fun projects
I completely took apart 5 Bombis and restored them over the last few years
I always put all new bearing in the complete machine and new bushings in the diff
One thing I learned is if your going to foam the tires get the rims sand blasted and either powder coated with epoxy paint .i found after a bit the tires start to move a bit on the rims
Water gets in and the rims rot and there’s nothing you can do
I had 3 disintegrated on me in the last 2 years the tires were filled when I got the machine
Have fun

Bombi is officially apart and ready for a “back to new” rebuild. I pulled the engine to redo the clutch and did a compression test while I had it out......and found a bad cylinder ....#2. Decided to mount the engine , pull the head.......and #2 cylinder has a “leak”. Not sure if it’s coolant or oil.....but taking the block/head in for a cleaning/pressure test. I’ll likely get a rebuild kit and make her like new. Luckily, the cylinder walls looked brand new....along with the cam and crank (I’ll have them checked for cracks as well). Oh.....didn’t notice a rear main seal leak until I pulled the transmission....40 year old machine, it was ready for some attention.











Having fun!

Bob

ÖÖÖ. by the ''dark'' color, oil soaked would be a good guess,... did it smoke ''blue'' when it first started. looks like a badly worn piston ring/cracked/broken,... plenty of carbon ''build-up'',... other cyls. not as bad. did you by chance perform a compression test. shine a light into the intake ports , to see if leakage was present; valve guide seal. a lot of engines don't use a guide seal on the exhaust, plus the heat & outlet flow ''wisk'' most evidence away. if you were ''passing'' coolant out of the engine, usually you would smell a ''sweet'' odor, or ''grey-ish / white'' smoke could be present sometimes, if no visible leak is obvious,... and lots of other things also,... to be continued,...

It sure did......lots of blue smoke. If itís a broken ring, the walls show no wear (cross hatch looks like itís a new engine).....making me think itís the head. There was quite a bit of carbon build up (on the valves too). Iíll follow up soon (engine went to the machine shop today)......pressure test will be key.

I rebuilt a Detroit diesel a few years ago due to a sweet smelling exhaust (head was cracked, fouled up a cylinder/piston.....walls were scored). Making me think (hoping)....its a stuck valve or the like on this Ford Industrial. Push rods, cam followers, crank.....they look perfect (fingers crossed).

Itís the journey.....having fun!
