School me on Oil injection delete.

[lshobie]

I'd like to remove the oil injection on my xlt, i need to make room for new cooler hoses for a tunnel cooler I am installing - the oil bottle is in the way. So the 98XLT has 4 injection lines, 3 to the cyls and one to the pto crank bearing.

So I am wondering what my options are:

1. leave pump on motor and use a small coolant bottle, remove and plump the lines back in to the bottle, or can I just cap the lines - seems like breassure would build up.

2. remove the pump and cap the inlets, then run a gravity feed to the pto bearing - but not sure if that would supply enough oil.

And what premix would I run, I read somewhere that SLP recommends 32:1 after their mod, I was thinking 40:1

Help appreciated.

Polaris sleds run happy at 40:1 (nice & easy to mix too, 1/2 quart per 5 gal of gas).

Premix is going to lube the bottom end for you, the PTO direct feed was just a little bit of extra insurance from Polaris/Fuji (after years of requests they finally relented and did it). Little gravity feed setup probably wouldn't hurt, but to be honest I wouldn't worry too much about it running premix.

The true key to PTO end bearing life on the monoblocks is making sure that the holes in the case halves are properly drilled and not obstructed when assembled. Fuji had a problem with this back in the late 1980s with the original Indy 500 liquids (service bulletin back then detailed the fix) and it reared it's ugly head again with the monoblock triples (especially the HO engines from late 1995 through early 1997). Although there was no official service bulletin/recall from Polaris on the monoblocks, enough of them spit cranks that it wasn't long before you could see the casting issue present and what needed to be done to fix them properly.
