But I thought if they had plastic cages, all the bearings are plastic cage bearings. At least the engines I've taken apart so far were like that. But they did make lots of changes as they went along
Interesting, I’ve never seen a cage with the connecting rod bearings. Seems all the engines I’ve done just have rollers that fit inside the open ends of the rod.
All the other bearings on this engine are the plastic cage type.
Hey now, I’ve actually never lost any rollers, just thought I did on this one because if the deceptive spacing. I’m certain now that this particular rod has the 13 roller set up, no plastic cage involved. The plastic cage I was referring to was for the crankshaft bearing that had a crack in it.
This roller situation may have just gotten a little more weird. Big thanks to JustO&R for providing the spare bearing rollers and plastic bearing cage! Good news is the plastic cage fit great. What is strange is when I started putting the connecting rod bearings back together I tried to use one of the spare rollers and there is absolutely no way to get 14 rollers in there. Everything measures out to be the right size
It seems odd to have almost a full roller gap in there but maybe it’s only suppose to have 13. That matches the set that JustO&R reference only having 13 as well. I put it all back together with just 13, guess we will see what happens.
I can send these spare spare rollers back to you JustO&R so you’ll have them when you need them in the future.
Ha, I saw that as well and was baffled. There have been quite a few Tiny Tigers on eBay lately I’m varying condition but they still seem to hover around $125-175.
Wow, very nice!
Do you think that is an original product or a custom use of an engine? It looks kind of like an O&R bicycle engine applied to a pumper cycle.
Hmmmm, very interesting. Let me take another close look at it tonight but I’m almost certain there is no way to get 16 in there. I wonder if they changed the ID of the connecting rod opening or went to slightly smaller OD rollers at some point. This 117 definitely looks like an earlier engine since it has the steel baffles, old style coil, etc.
Thanks David- I was starting to get confused as well between the versions. This Type 117 only has room for 14 (at least for the size rollers it came with).
Does anyone by chance have a couple spare, used bearing rollers that go to the bottom (large) end of the connecting rod? I was thinking there may have been one missing when I took this engine apart and now that I’m reassembling it I’m certain once is missing. I think there are supposed to be 14 of these rollers and there are only 13.
