Rod Bearings?

[ckhorne]

I see on the compatible parts list that the compatible part for rod bearings are Clevite 77 CB-811G.

Amazon sells them here, but I don't know which size (or even what that size measures.

Does anyone know specifically which one I need?

That's something that your machine shop would tell you. It depends on the wear on the crank journals, or if the crank gets turned.

I checked the Amazon site, and depending the size, Standard, 0.25mm undersize (0.010"), 0.50mm (0.020") and 0.75mm (0.030") and so on, are marked in the description, like the following:

Clevite 77 CB811G.50MM Auto Part will correspond to 0.50mm undersize, or 0.020"

What size are you looking for?

Ahhh.. it all makes sense now - I didn't think about the different sizes being dependent upon wear or being machined.

I'm having the head machine now. I'll contact my machine shop guy and ask for his input.

Thanks for the help, and pardon my ignorance.

Thanks to you for finding those connecting rod bearings. Always good to have another source.

I saved some time ago the following information from an Australian manufacturer, ACL. The link corresponds to the P engine

http://catalog.acl.com.au/aclwebcatalog ... e=0&pg=all

Searching some of the individual part numbers, I was able to locate some of them here in the States, in case you need some other items as well.

Post some pictures of the parts at the machine shop, if feasible.

I can't help you with specific part number, but I can share a tiny bit of what I know about the P engine and where I found parts. Simply put, it's messy -- In my experience, engine internals are hard to come by. The P matches the P40 forklift engine for all but main bearings. The mains match the PPU forklift engine. Standard mains seem to be non existent -- I just had to have my crank turned to match the 0.010 bearings I could find! Anyway, I'm happy with Motor Power Inc. --

Here's the link to what I bought the first time (and more importantly, I followed Bosque's post about engine internals. I refer to it in the post so you can get there):

The gasket set from Motor Power, Inc. works except for the side cover (tappet cover) and the timing case to block gaskets and both the front and rear seals. The rear main seal was so tight it could not be forced it at all. We used a chevy 292 seal for the rear main. I bought a second full gasket set from datsun311parts on ebay for the incorrect gaskets -- very expensive! For my second engine, I used the first set and cut my own gasket for the timing case. I'll probably do the same for the side cover as well as the side cover gasket in the datsun311parts set was cut slightly too small and was a pain) As for the front main seal... I'll likely do the match up at my local parts store. In other words, I'd buy the forklift gasket set from Motor Power and then cut my own gaskets for those that don't fit... Now that I've strayed far, far away from rod bearings...

Good luck! Let me know if you need any specific part numbers from my sets (there are pictures of most of the PNs. in my family patrol thread).

John-

I've been reading, re-reading, and taking notes from that thread - it's been hugely helpful!

I bought this set off ebay before I read about your problems with matching the gaskets up. At this point, I'm going to use as many of the gaskets in the kit as I can, but my fallback is to use your gasket pictures to cut my own for the ones that don't fit.

As for the rod bearings, I'm only having the heads machined, so I think I'm safe with going with the standard size, but I'll ask my guy. Sorry- I can't provide any pictures from the machine shop. I'm doing this myself, and guy doing the machining work is slipping it in "on the side" with his machine shop... it sounds more sketchy than it actually is ... in either case, there won't be any pictures except the ones from my garage. And since I've been meaning to start my own project thread, I'll do that now.

You'll be fine with the standard rod bearings, knowing how long these engines last. Regarding the gasket set, that's all that you need. Either go the route with the scanned gaskets from John, or do the way I've been doing for over 20 years: use any silicone gasket maker, like Permatex High-Temp Red RTV Silicone Gasket. I had even use it for the oil pan.

Good luck with you rebuild.

Thanks for the insight. I have a large tube of high-temp RTV on the ready when I start the rebuild.

An odd thing my machinist said was to use the gasket and/or 100% silicone. Yes, the clear stuff - pure silicone used to seal windows and stuff. I questioned him, and he said it just worked more consistently and gave a better seal than RTV. Still.... I have my tube of RTV ready...

Difficult to argue with him about the rationale to use the clear one. I personally will only use the ones for the intended use, either the red, black or gray. I definitely will not use the combination of silicone and gasket. The too will argue with each other on whom is at blame for the leak.
