wanted chev 216 20thou under main bearings

[Col Tigwell]

Egge have been around for a very long time. I purchased a set of light weight pistons and rings from them in the 70's for my model T. Top notch gear and have served well.

Thanks to all for the replies
I have sent them a email so will see how that goes

I found egges service and delivery to be quicker than Carters , they stocked u/sized bearings that were not available else where and in the case of bigend shells you could buy individual pairs at very reasonable prices.

UPTONS at Corowa had them ..030 and 040 undersize ..Australian made NASCO brand ( GMH ) . $5 a set . they sat for years along with the big crate of 040 216 pistons ..no-body wanted them year after year we went there during the 1980's and 90's. A case of you never need this stuff till its all gone !

The 216 engine that was used in the chev blitz was made in Canada from 1937 to 1945 and this can be identified by having a single hole from the waterpump to the block and having dome top pistons .

This same engine was produced in the USA from 1937 until 1940/41

In 1940/41 the engine underwent a change in the USA and came out with two holes going from the water pump to the block and flat top pistons plus other internal engine changes , this engine was produced until 1947.

Australia in 1942 received from the USA a considerable number of chev trucks Model M 160'' W/base for war support ( in Aust we call them Lend/Lease trucks ) .
It is possible over the years that these engines have become transplanted in blitz's or vice versa and this make ordering engine parts a bit tricky , when ordering parts on line from the USA keep in mind that blitz engines are the 1937 to 1940/41 engine .

Jim Sewell raises a very good point in his post about domed pistons and water pump changes, which fits right in to the thread http://www.mapleleafup.org/forums/sh...ad.php?t=12592 (I'll post the piston listing pages on that thread.)

As to the water pump the picture below shows a `41 style water pump single inlet and the later 2 inlet + vent of the second style as you can see these are not interchangeable. This becomes very evident in the second photo which shows the gasket for two hole on the `41 single hole, as you can see the inlets don't line up nor do the mounting bolts.

Has anyone got the original part numbers for the main bearings on the cmp 216 ?
Thanks

Yes on all of that Jim. And , on the 216, the push rod length and lifters changed at 1940 - push rods are shorter than 1939.

Another difference from 41 on, and this applies to the local GMH assembled 216 engines : the valve spring caps changed - from memory this affects the valve stem length. I've got a GMH notation somewhere , explaining it.

In an earlier post I listed std bearings from Nasco , here are the .020'' u/s

Front 3847200 37/47
F/Int 3847201
R/Int 3847202
Rear 3847204 40/47

Repco would have 020 tacked onto the existing number .
If you come across other brands of bearings I maybe able to cross referance.

The push rod part number for the 1940 chev is the same part number as the Blitz so these must be 1940 engines in blitz's, this push rod went from 1940 to 1952.
On the 235 chev motors ( 1946/52 ) fitted to Maple Leaf and 15 series spash feed , these push rods were about 3 mm longer and this is an easy way to tell if you have a 216 or a 235.
GMC have similar crankshaft journal sizes but differ in the locating tang / dowel arrangement.
