ahhh yes.. the shim.... that is true. the snout of the crank shaft protrudes an extra .100 ish out of the block. so if MMR supplied you with a crank gear, you will see that the back side of it has a relief machined into it. so your crank timing gear will sit in it's normal position.
if a crank gear is not with your setup. contact MMR for it or machine the resess on a large. if you don't your timing wheel will rub and or fly cut into your timing case.
thanks everyone. the issue in question is the 2 shims for the thrust bearing. I understand the shims fit on each side of the thrust. My concern is the shims still move after in place. I am afraid they will rotate out and destroy my engine.
yes. I spoke to MMR and they said to use a punch to set them. Issue is now since a used a set punch to take up the small difference so they would lock down, the thrust is now a tad wider and fitting to tight in the journal. Now I have to use a emery cloth to remove metal on this internal side of the thrust walls to reduce the difference the punch tabs made.
now I see why building your fist engine is not for a beginner.
I have a fully built from mmr teksid 1000se, built for boost with piston notching, I have had it sitting since May, I bought it in may off a fella who had a eBay post trying to sell poor guy forgot to put a reserve so I won he auction at 2k. It costed me 2500 shipped to me he had it sitting in a climate controlled room for 2 years. The paper work shows he paid close to 9k usd for this set up as is, mmr knowing the engine is for a 2v did t even drill the water passage hole for a 2v head. I’m having the pistons and rods changed out on the block since I want higher compression and I’m now debating just taking everything out and selling the parts for what ever I can get and build fresh through my builder, every mustang builder in Canada where I am from hates mmr and won’t touch there engines due to nothing but trash engine builds. I am using the best engine builder in Canada and I’m scared what he is Going to say about the whole shim thing lol, don’t really want to buy a new assembly unless I can get my money’s back for what i spent
