450c Complete overhaul
450c Complete overhaul
So I found a 77 450c from a childhood friend that has been parked for 10 years. (not inside or with a cover over the muffler). The plan was to see if motor was locked up or not, well long story short the motor was locked up. After dissassembling and sending to a machine shop, found out the block was cracked in the sleeve. After adding up what it would cost to rebuild I just went and bought a re-manufactered 4039t. WAAAAYYYY cheaper than rebuilding old motor. This one came with all new JD OEM parts and was dyno tested. Heres some pics of how I found it. Progress pics to come!
I have receipts from right when he parked it in 06, Basically all new undercarriage with new trans. So i knew after a good motor she would be ok...
Engine removal!
Frame rail repair on both sides and gusseted for strength
Off to get Sandblasted! Stay tuned

I got the motor off of ebay from government liquidation, it is not a re-furb its a re-manufactured which means basically they change all parts out with OEM john deere parts. Motor Is brand new from starter to turbo. Its rated i think right at 100 hp. But way better fuel system and 24v starter and alternator should make it easier to start. Wanting to build a foresty Cab and put limb risers and muffler riser.

Since no one else has chimed in, I'd think that if no water got in, the transmission should be fine. I'd check the accumulator though. Being high on the machine it may have some rust from condensation in it. It acts like a shock absorber during forward/reverse shifts and the adjustments can be finicky. Best wishes. Paul

Re: 450c Complete overhaul
