Lynx II, hull # 4225

[Peter Duggan]

Guys,

Christmas came in a plain crate. Thanks to the great workmanship of Dave Good aka Super Dave, I now have a reconditioned 239 for the Lynx. Dave even ran up the engine as part of the rebuild.

Now to finish a few items in the engine compartment and the engine itself and I will move on to a major milestone.

OK - all well and good - but I've been losing sleep over the pulley problem..

Hi Peter,

Your engine looks pretty good to me, but do you have the correct intake manifold? According to the Canadian Lynx I Mk.III and III* (SC F1 and F2) from hull number 1069 the carburetor was reversed so the the fuel bowl faced the front of the vehicle not the rear. From your photos it looks to me that the carby is facing the front of the motor not the rear as it should be. (Of course they may have changed it around further down the production run, but I don't think so.)

Here is a copy of the relevent bit from the manual on page Q-8.

Charlie,

Welcome to the club. I have decided to defer installing the engine until I can sort out the issue with the pulleys. I did temporarily install the generator to see how those pulleys lined up with the others. Seems to line up better with the crank pulleys. Both seem to stick out further than the water pump pulleys.

My original engine was stamped C81T-LH on the LH head while the rebuilt engine has C7RA-A cast on the LH head. I have yet to find any differences between the two engines. The shaft from the crank is 3 1/16" from the edge of the block to the end on both engines.

I brought the Lynx home to keep me challenged both mentally and physically. She's doing a great job. Tomorrow is another day.

Rick,

Sharp eyes. I didn't pick that up until I went to install the generator. Wish all fixes were that easy.

Guys,

I welcome all and any suggestions.

Peter

From looking at your pictures I would say you need different water pump pulleys as shown in this picture which stick out further as you can see the pulley groove is almost flush with the end of the shaft compared with the offset ones you have now.

[Wayne Hingley]

I think you are right Dave. Can the current pulleys be flipped around, so the offset is toward the end of the shaft?

[Wayne Hingley]

I think if the pulley in the top of this photo was flipped around (so the cone-shaped portion is close to the engine), the belt would be more aligned with the crank pulley and generator.

The C81T heads are "handed" left (6049) and right (6050) These are for pre 42 engines.
while the later C7RA heads fit on either side. The early heads fit the early blocks, but need to be relieved at the valve chamber to fit on the later blocks.(the valve line was moved up hill in the 42 engines)
The C7RA heads come in either Iron or Aluminium. The Ali is higher compression than the cast. Both types of C7RA heads are Higher comp. than the C81T heads.
The manifold required has the facility to fit two sets of 3 carb mounting studs.
on its carb mounting face.
