Motor Rebuild

Postby Mr. Recovery » May 23rd, 2010, 7:08 pm

As some of you know, I pulled and disassembled the motor from "Betty Mutt" about 4 years ago :shock: After moving to Florida and working on the body for a year I decided to work on the motor again, I took it to a local Machine Shop and had it cleaned, bored .020 over, new pistons fitted and all moving parts balanced, I picked it up about 2 weeks ago, sinch then I have been recleaning all the parts and getting ready to reassamble it.

Camshaft and Crankshaft installed

I'll give the cam lobes a good coat befor the pan is put on.

Pistons and rods ready to put together.

Lookin good Mr. R! Good luck with the lock-rings. We've all been in your boat at some point and Im positive you will find or get replacement retainers. Keep us updated.

Huge thanks for the detailed info as well :!: :!: :D :D

Thanks! :D I have sent out some e-mails to parts suppliers that have them listed but don't show a price, so far, Blake Callaway of Red River Parts & Equipment has had every part I needed except 1, they are very nice people to deal with and I got everything i ordered in 3 days. :D
I have an open motor at work that I can pop a piston out of if I must. I'll keep the photos coming as the work progresses.

Hi, I was able to "liberate" 2 lock rings from the motor at work, sure is nice to have a scrap pile to pick throught. 8) Yesterday I put the last piston pin in place and started on putting them back in the block,

first I had to put the expansion plugs in the rear of the block.
Image

Image

Image

Image

then I put the block on the engine stand.
Image

Image

put the other 2 expansion plugs in.
Image

pistons ready to go.
Image

a dip in a 50/50 mix of motor oil and assembly oil.
Image

Image

swab the cylinder with the same oil mix.
Image

install pistons with the bearing in the rod. #2 and #3
Image

Image

Image

Image

install and torque rod caps.
Image

Image

rotate crankshaft and install #1 and #4
Image

Image

torque #1 and #4 then recheck all.
Image

Image

Image

Image

My nephew came over to tell me that dinner was ready and took the last 4 photos to hurry me up. :D

Looks great Dan, what did you use to soak the block in (green stuff?) How much is reasonable to have an engine balanced?

The cleaner in the tub is a biodegradable machinery cleaner that you dilute with water, I picked it up at Harbor Freight.
The machine shop charged $150.00 to balance the engine. The total to bore and hone the cyl's to .020 over, remove and replace the cam bearings, polish the crank, check and clean out all oil holes, hot tank the block and the balance job was $365.00

Thanks!
